New Report Suggests Distributed Ledger Architecture for UTM Systems

Cranfield University published a report this week exploring some questions about the development of an uncrewed traffic management (UTM) system. The document is the result of a research partnership between Cranfield, Heathrow Airport, Oxford University, International Airlines Group (IAG), NATS UK, SITA, and multiple other U.K.-based startups and enterprises.

The central objective of the report, coordinated by Dr. Dimitrios Panagiotakopoulos of Cranfield University, is to analyze the potential of cross-cutting technologies—in particular, artificial intelligence (AI) and distributed ledger technologies—and to demonstrate the need for increased collaboration between all stakeholders of the integrated aviation ecosystem. This includes UTM service providers, digital network providers, uncrewed aircraft operators, infrastructure providers, air navigation service providers, and regulators.

The authors of the paper also underscore the importance of trust within the UTM ecosystem and suggest a governance framework that establishes rules for the above-mentioned stakeholders occurring in a distributed ledger, creating a safe environment that participants can trust.

“Drones will create new forms of traffic especially at very low levels of airspace with high demand in densely populated areas where risk levels will be increased,” according to the research group. To ensure safety in this growing ecosystem, with a variety of vehicles operating in the same airspace, the UTM system needs to include new and updated procedures.

Technology that is outdated or unreliable is a big concern in the aviation industry, according to the authors of the paper. They reference a study done by Cranfield University which estimated that, of flight delays that are not due to weather concerns, 60% are a result of failures with data handling. The solution? A new “system-of-systems” that includes cloud infrastructure and distributed ledger technologies (DLTs) with blockchain-style information sharing. Using a decentralized system could lead to more secure airspace management. However, there is still work to be done regarding regulations for drones operating beyond visual line of sight (BVLOS), and accounting for varying levels of autonomy in the airspace.

As urban air mobility (UAM) operations scale up, the authors of the report predict that “pilots will likely fly the first generations of electric vertical take-off and landing (eVTOL) craft in-vehicle, long before remote or even autonomous operations are proven to be safe.” This is because a pilot is trained and able to detect and avoid risks, and can also “make balanced and intelligent safety choices with full situational awareness,” the paper concludes.

But as demand for UAM increases, operations will become more and more dependent on AI. And an ecosystem that relies significantly upon AI needs to have trust—and resilience—built into its digital infrastructure.

“Truly distributed approaches are now available, to make the underlying digital infrastructure of our UTM and ATM systems reflect the real-world interactions of its users and stakeholders rather than enforcing a one‑size‑fits-all approach,” the report claims.

The researchers bring up a few obstacles to realizing a modular and interoperable distributed system approach for uncrewed traffic management. One challenge is technological instability—blockchain is still a relatively new concept, and stakeholders will need to consider the possibility that a better solution may soon emerge, as well as the risks involved in not taking action.

A UTM solution based upon a DLT architecture can also be susceptible to cybersecurity risks because of the permanent nature of records in a distributed ledger. The report cautions that the encryption methods and contents of messages should be considered in order to maintain system security.

Safety and security are also key priorities for Belgian UTM system provider, Unifly. The company recently received €10 million in funding, and they will use that investment to ensure that their UTM system functions based on some of the same findings featured in Cranfield University’s report, Unifly’s co-founder recently told Avionics International. The company also enabled automation for parts of the approval process for drones operating within controlled airspace, as part of a collaboration with air navigation service provider NAV CANADA. Automating this process helped to decrease risk for drone operators while also increasing situational awareness—for both air traffic controllers and operators.

Airbus completed a successful first test flight of the A321XLR in Germany, the Toulouse-based aircraft manufacturer announced Wednesday.

The A321XLR is the latest extra-long range variant of the Airbus A320 family that features a 700 nautical mile increase over the A321LR. During the maiden flight, lasting 4 hours and 35 minutes, the Airbus test pilots and engineers evaluated the aircraft’s “flight controls, engines and main systems, including flight envelope protections, both at high and low speed,” according to the company.

Three fully-instrumented A321XLRs using CFM’s LEAP-1A and Pratt & Whitney’s GTF engines are being evaluated as part of the flight test campaign that will also use one A321neo prototype in the earlier phases.

The flight test instrumentation inside the A321XLR cabin featured in a presentation shared by Airbus.

Airbus developed the XLR with a focus on maximizing commonality with the rest of the A321 family, introducing only changes necessary to achieve the longer range. Among those changes are a permanent rear center tank to hold more fuel, modified landing gear to improve maximum takeoff weight to 111 tons and an optimized wing trailing-edge flap configuration to preserve the same take-off performance and engine thrust requirements as the A321neo.

Philippe Mhun, Airbus EVP Programmes and Services, described completion of the first test flight as a “major milestone for the A320 family.”

“With the A321XLR coming into service, airlines will be able to offer long-haul comfort on a single aisle aircraft, thanks to its unique Airspace cabin,” Mhun said.

Leading up to the first flight of the A321XLR in Germany, engineers back at the Airbus headquarters in Toulouse have been virtually testing the aircraft systems in a laboratory filled with numerous racks containing modules that are identical to those inside the avionics bays of the three A321XLR flight-test aircraft. The modules are directly linked to the company’s Development Simulator, “S22,” allowing the engineering test pilots to validate the A321XLR’s “modified flight control system laws, in specific conditions—such as during flare or during high-speed flight,” according to Airbus.

Middle East Airlines (MEA) is the launch customer for the A321XLR, which has amassed 500 orders from more than 20 customers, according to the latest aircraft order data released by Airbus.

MEA’s first A321XLR is expected to be ready for passenger-carrying flights by 2024.

Overair Just Received $145 Million in Funding for eVTOL Development

Overair, the Santa Ana, California-based electric vertical take-off and landing (eVTOL) startup, just announced that it is receiving $145 million in funding for continued eVTOL development. The funding comes from the aerospace division of Korean conglomerate Hanwha Systems. Overair plans to fly a prototype of its eVTOL, called Butterfly, next year.

Josh Aronoff, Head of Business Development for Overair, spoke to Avionics about the new funding and the progress made with Butterfly so far. “Financing should support strategy and never vice versa,” he remarked. For Overair, their strategy is “to build not just a superior aircraft but a superior aircraft company.”

Overair originally began as a spinoff of Karem Aircraft in 2018. Aronoff explained, “When Uber started populating this concept of urban air mobility [UAM] using electric VTOL aircraft with batteries that aren’t that great in terms of energy density, the efficient VTOL propulsion IP happened to be a great fit.”

The company has taken the IP surrounding VTOL propulsion that it owns to work towards its objective of operating aerial ridesharing services in densely populated urban areas. The company first revealed the design of Butterfly last August, sharing that the vehicle would employ a vectored thrust configuration to enhance efficiency in flight.

Overair’s commercial strategy is to be a fast follower, said Aronoff. He acknowledged that Butterfly will not be the first eVTOL aircraft to achieve certification. Their team instead focuses on building a capable aircraft designed for a long-term market that will take the most efficient path to certification. Part of the reasoning for this strategy is the company’s belief that all of the necessary infrastructure and airspace management will not immediately be ready when the other eVTOL developers receive certification.

The team is currently wrapping up propulsion testing, which commenced in January, evaluating the propulsion system’s performance at flight speeds—both in vertical and forward flight mode. The resulting data is pushed to Overair’s engineers in Santa Ana as they continue development.

“We are now shifting gears to integrating our prototype, which will be flying mid- to late next year. Part of being on the most efficient path to certification is building a prototype at the point in time in the development program that allows the engineers to get the most out of it,” he explained.

“The utilization of aircraft is really driven by performance metrics that people aren’t focused on yet,” Aronoff commented. The design of the Butterfly eVTOL is unique—in particular, the rotors on the aircraft are quite large. This offers Overair significant power margins, even with weak battery cells, to enable all-weather operations. The larger rotors spin more slowly and have a lower disc loading, he added, and they have a low noise profile.

The team at Overair expects their aircraft to be the most capable eVTOL for less-than-ideal environmental conditions. “When it’s not nice and sunny outside, are you going to be able to make your flight with the eVTOL when you planned your schedule around the 15 minutes it takes?” asked Aronoff.

In addition to integrating their prototype, Overair is focusing on downselecting suppliers for their eVTOL’s major aircraft systems like the fly-by-wire system, flight control computers, and other avionics, Aronoff stated. “Hanwha Aerospace will be developing our prototype battery packs and electric motors,” he added. Hanwha offers Overair more than just the $145 million in funding. The conglomerate is considered a global leader in ancillary UAM services, Aronoff said, such as communications, connected vehicle, and ground infrastructure systems.

Having Hanwha as a strategic partner has enabled Overair to focus on the engineering and technical development side of the business as well as building out the Overair facilities. The headquarters are located in Santa Ana, California, and they have a flight test facility complex in Victorville.

Overair has also been working in collaboration with Bristow Group, a global provider of sustainable vertical flight solutions, since the two companies announced the signing of a Memorandum of Understanding (MOU) last December. In addition to contributing to development of a framework for growing operations, Bristow placed a pre-order for up to 50 Butterfly eVTOL aircraft.

According to Aronoff, the team’s main technical achievement so far has been the full-scale propulsion testbed. Because the rotors are so large—the diameter measures 20 feet wide—the testbed is too big to test in wind tunnels. Instead, Aronoff shared, they are testing it out in the desert at their flight test facility. This is “extremely useful to validate all of our modeling, thrust metrics, sound metrics, everything.”

The company has previously stated that it expects to achieve certification in 2025 and launch commercial services in 2026. Aronoff confirmed that their timeline is in the mid-2020s, although there has been a lot of recent uncertainty around the FAA’s exact process for certification, he noted. However, the FAA “has been very outspoken to say that it will not delay the timeline” for eVTOL certification.

Joby Receives Part 135 Certificate From FAA Ahead of Schedule

The Federal Aviation Administration has awarded Joby Aviation a Part 135 Air Carrier Certificate, permitting Joby to begin commercial operations of its electric air taxi. The company originally expected to receive the certificate for its vehicle—an electric vertical take-off and landing (eVTOL) aircraft—in the second half of this year. Earning the FAA’s Part 135 Air Carrier Certificate is necessary for developers of eVTOL aircraft and uncrewed aircraft systems (UAS) in order to begin operations in the U.S.

“Receiving our Part 135 Certificate has been a key priority for Joby’s air operations team,” a representative from Joby told Avionics International, explaining how they achieved this milestone ahead of schedule. “The work on our certificate also fit the FAA’s timing well.”

Joby’s team expects to begin passenger-carrying operations in 2024. After receiving the Part 135 Certificate, the representative shared, they will now place their focus on developing operational experience and validation of their supporting software.

Joby’s second pre-production eVTOL prototype has already performed numerous tests—both flight tests and ground-based taxi testing. This prototype was awarded the FAA’s Special Airworthiness Certification and also received airworthiness approval from the U.S. Air Force. And just a few months ago, in March, Joby announced completion of its first Systems Review and Compliance Review and the FAA’s approval, as well as the start of manufacturing its first production-intent aircraft at its facility in Marina, CA. Joby also shared in March that it had begun the fourth of five stages necessary to receive the Part 135 Certificate. The eVTOL developer initially applied for the certificate in June 2021.

For the remainder of 2022, Joby’s efforts will be geared towards three objectives, the representative explained: aircraft certification, scaling manufacturing, and preparing for commercial operations.

To support Joby’s pursuit of type certification for its aircraft, the company recently announced its acquisition of Avionyx, an aerospace software engineering firm. Through this acquisition, Joby will integrate Avionyx’s team with its own. Avionyx offers Joby extensive experience in software development and verification in accordance with the FAA’s airworthiness standards.

Joby’s spokesperson offered an update on manufacturing of its first production-intent aircraft: “We continue to make good progress with the majority of the large composite parts already manufactured and work underway on the tail and wing structural assemblies.”

“We will use the Part 135 certificate to exercise the operations and customer technology platforms that will underpin our multi-modal ridesharing service,” the representative stated, “while also refining our procedures to ensure seamless journeys for our customers.”

Archer Aviation, another U.S. eVTOL developer, is in the process of working to complete the G-2 Means of Compliance with the FAA. Archer’s team expects to achieve this by the end of 2022. In a letter to shareholders, the company announced last year that “we anticipate receiving our Part 135 Certification, a critical certificate which is required for the commercial operations of our aircraft, in 2024.”

In addition to working towards FAA certification of its aircraft for operations in the U.S., Joby is collaborating with ANA HOLDINGS, the parent company of All Nippon Airways (ANA), to bring eVTOL operations to Japan. The joint efforts were announced earlier this year. Joby and ANA will coordinate for a range of activities including infrastructure development, pilot training, and air traffic management. The collaboration will also explore the regulatory requirements for operating Joby’s eVTOL in Japan.

AutoFlight Releases Test Flight Footage of Its Second Proof-of-Concept eVTOL

The company AutoFlight, electric vertical take-off and landing (eVTOL) aircraft developer, released a new video of its Prosperity I vehicle’s full-scale, proof-of-concept test flight last week. Mark Henning, Managing Director of AutoFlight Europe, told Avionics International in an interview that its aircraft have completed more than 200 tests, and the configuration of Prosperity I will be finalized by the end of this year.

“The most important design goal for Prosperity 1 is a very low total cost of ownership,” said Henning. He sees this as one of the key competitive advantages of AutoFlight’s aircraft. All of the components that they procure must be cost-effective, he added. This advantage is also somewhat of a challenge when it comes to deciding what to develop and build in-house at AutoFlight, and what components should be purchased from suppliers. With so many parts, including ten motors on the aircraft—eight for lifting vertically and two for propelling the aircraft forward—it makes a difference if a component costs €10,000 or €20,000, Henning explained.

The Prosperity I has a 200km range, a 180km/hour cruise speed, and the capacity to carry three passengers in addition to a pilot. Their “lift and cruise” configuration is designed to be mechanically simple, “which is important for flight safety, weight, and production cost,” Henning noted. “It’s very low-cost for maintenance—virtually no gears or mechanical components.” In the transition phase, the propellers for vertical lift are switched off and the aircraft enters fixed-wing flight mode.

In Shanghai, AutoFlight has a facility for rapid prototyping where they built and flew a proof-of concept (POC) aircraft at the end of 2021. The successful transition test flight of POC #1 was announced in February, making AutoFlight one of the first eVTOL developers to complete a transition flight. Their POC #2 is the model featured in the announcement last week, and the aircraft can be seen completing a full test flight in the accompanying video footage. According to AutoFlight, the updated model includes upgraded lift and cruise configuration, optimized lifting propellers, and enhanced efficiency in hover and cruising modes.

Although the video of AutoFlight’s POC #2 transition test flight was just released last week, the team has performed at least 30 successful flight transitions in the last several weeks. Production of the POC #2 began in January. At that time, AutoFlight also announced the establishment of its first location in Europe. Henning, formerly a manager at Airbus, leads a team at Autoflight’s R&D and certification center in Augsburg, Germany.

“We are now testing a single propeller configuration versus a twin pusher propeller,” Henning shared. “It’s more efficient, lower in weight, and it’s less noisy.”

He noted that their POC aircraft are all built in full-scale configurations for flight testing “because the aerodynamics and loads are not linear. You cannot extrapolate from what you are testing [at subscale] because it’s nonlinear.”

“We are trying to solve society’s transportation problems, and the first markets pushing for AAM/UAM solutions are going to be mega cities,” said Mark Henning, Managing Director of AutoFlight Europe, in discussing where they plan to launch the Prosperity I eVTOL aircraft.

Once the design configuration is finalized, AutoFlight’s team will apply for type certification with the European Union Aviation Safety Agency (EASA). Says Henning, “The plan is to finish certification at the end of 2025, to field the first aircraft with customers in 2026.” For certification testing, the team will build multiple conforming aircraft prototypes.

AutoFlight’s eVTOL aircraft has a full authority fly-by-wire avionics and flight control system. “These kinds of aircraft have peculiar control laws which have to be implemented and developed ourselves,” Henning explained. They have used both proof-of-concept aircraft to develop the control laws, he continued, that have to be implemented in the flight control system. This is something that all eVTOL developers must complete, he noted, and none have yet certified this kind of system with either EASA or the FAA.

The U.S. Air Force is upgrading its fleet of C-5M Super Galaxy Transport aircraft with new cockpit displays under a recently announced contract with Intellisense Systems, a Torrance, California-based supplier of aircraft sensing and display electronics.

According to a June 7 announcement from Intellisense, the contract will provide “Replacement Multi-Function Controls and Displays” (RMCD) for the military cargo transport planes. Intellisense will replace the C-5M’s existing displays with an upgraded version of the video display terminal or VDT-1209s that is currently in operation on the MC-130J.

Some of the details on the upgrade released by Intellisense confirm that the upgrade will be enabled by the PU-3000 multicore avionics computer first introduced by CMC Electronics last year. This selection of the PU-3000 comes a year after it became the industry’s first avionics computer to use multicore processors certified to design assurance level (DAL) A, the highest level of assurance requirements imposed by civil aviation authorities for safety critical aircraft hardware and software.

The existing C-5M cockpit configuration includes six multi-function smart displays that provide the pilot, copilot, and flight engineers with primary flight and navigation information, according to Intellisense. All six displays will be replaced with the company’s large-format 15-inch display and three separate GPU line-replaceable units (LRUs).

There are currently 52 total C-5Ms in operation by the Air Force. At a length of 143 feet and 9 inches, and maximum takeoff weight of 840,000 pounds, it is the third largest aircraft in the world and the largest in the Air Force inventory.

Lockheed Martin first started delivering the C-5M to the Air Force in 1970, and the aircraft has undergone several avionics refresh programs over its 50-year lifespan. The most recent one includes development work that first began in 2014, and continued into the 2020s, with the Air Force’s fiscal 2021 budget request including $50 million dedicated to communication, navigation, and surveillance/air traffic management (CNS/ATM) upgrades, according to previous reporting from Defense Daily, a sister publication to Avionics International.

Jack McParlane, director of business development in Intellisense’s airborne systems department, in a statement, called the C-5M RMCD win “an important step” for the company. “Not only will we be providing a Primary Flight Display for an essential USAF aircraft, but we will also be integrating and delivering the full C-5M cockpit display system, including state-of-the-art, multicore avionics computers from CMC Electronics,” he said. “The program scope further demonstrates our ability to address flight-critical avionics beyond just displays.”

A team of U.K. companies led by Inmarsat has broadcast a satellite navigation signal in a project to explore a United Kingdom sovereign positioning, navigation and timing (PNT) system. Inmarsat announced Wednesday the signal is stable and operational, enabling on-going testing and validation by industry, regulators, and users.

The United Kingdom is no longer part of Europe’s Galileo satellite navigation system after leaving the European Union, and cannot use the European Geostationary Navigation Overlay Service (EGNOS) safety of life services, which provide GPS for airport approach and landing operations for aircraft.

Inmarsat is testing a potential sovereign solution, the UK Space Based Augmentation System (UKSBAS), with British partners Goonhilly Earth Station Limited and GMVNSL Limited. UKSBAS repurposes the SBAS transponder on Inmarsat’s I-3 F5 satellite located at 54 degrees West. Inmarsat announced the project in December 2021.

Inmarsat said UKBAS is designated to provide more precise navigation for maritime and aviation users in U.K. waters and airspace, increasing accuracy in positioning to a few centimeters of accuracy rather than the few meters provided by standard GPS.

Nick Shave, vice president of Strategic Programmes for Inmarsat Global Government said the program allows Inmarsat to extend the live of its I-3 F5 satellite, two decades after its launch.

“We look forward to exploring the potential for this project and the benefits it could deliver to the U.K. with more precise, high-integrity, resilient navigation services, whilst also exploring future capabilities on new satellites through Inmarsat’s fully funded technology roadmap. This work also has the potential to be exported to other nations around the world, benefitting the U.K. economically as well as technologically,” Shave said.

Raytheon Technologies on Tuesday said it will establish its global headquarters in Northern Virginia, close to many of its government customers in the Washington, D.C., area, a move that follows Boeing’s decision a month ago to relocate its corporate headquarters to the region.

Raytheon said it will be moving to Rosslyn, an area of Arlington Virginia across the Potomac River from Washington and the same neighborhood as its Intelligence & Space operating segment. The company is currently headquartered in Waltham, Mass., near Boston. Collins Aerospace, Pratt & Whitney, Raytheon Intelligence & Space and Raytheon Missiles & Defense are the four individual business units overseen by Raytheon Technologies Corporation, according to the company’s website.

“The location increases agility in supporting U.S. government and commercial aerospace customers and serves to reinforce partnerships that will progress innovative technologies to advance the industry,” Raytheon said. “Washington, D.C., serves as a convenient travel hub for the company’s global customers and employees.”

Boeing in early May said it would be moving its headquarters from Chicago to Arlington, where its defense business is based. Boeing also said it would create a research and technology hub as well in the Washington area.

General Dynamics and Northrop Grumman are also based in Northern Virginia and Lockheed Martin is headquartered in Bethesda, Md., adjacent to the beltway around Washington. These three companies combined with Boeing and Raytheon make up the five largest U.S. defense contractors.

Raytheon said that it already employs about 130 corporate staff in Rosslyn and doesn’t expect personnel there to increase significantly with the establishment of the new global headquarters. The company will slightly increase its leased space in Rosslyn.

Raytheon has a substantial operational presence in Massachusetts and will maintain its presence in the state and in Waltham. The company said the new global headquarters won’t impact its employee totals in Massachusetts or Virginia.

In the internet era, combined with the workforce shocks of the COVID-19 pandemic, many private and public sector employees and leaders have shifted to a hybrid work model that includes home and traditional offices, and some employees are fully remote, with less frequent office visits.

CoreAVI, DDC-I Target Development of Next Generation Avionics Apps with New RTOS Graphics Platform

(Photo: CoreAVI)

Phoenix, Arizona-based operating systems and software supplier DDC-I, Inc. and CoreAVI, the Tampa, Florida-based provider of safety critical computing, have partnered to introduce a new integrated avionics real-time operating system (RTOS) graphics platform that could accelerate the development of compute and graphics-intensive avionics applications, according to an announcement made by the two companies last month.

The two companies have confirmed that the partnership will target the development of a new integrated avionics RTOS/graphics platform for “high-performance multicore SoCs equipped with on-board graphical processing units (GPUs), including the NXP i.MX 8 and 11th Generation Intel Core i7 (formerly Tiger Lake).” Some of the specific avionics applications that could see accelerated development resulting from the new platform include those requiring data fusion, sense/detect, synthetic vision, graphics, and other advanced control functionality.

By combining DDC-I’s Deos RTOS with CoreAVI’s Vulkan-based VkCoreSC graphics and compute driver portfolio, the partnership combines technologies that both companies have continued to win new avionics embedded development contract awards for in recent years. As an example, Deos was also confirmed by DDC-I to provide RTOS hosting for Honeywell Aerospace’s Anthem cloud-native cockpit system.

First certified to Design Assurance Level (DAL) A in the late 1990s, the Deos RTOS has been used to host DO-178 certifiable avionics software including functions such as air data computers, air data inertial reference units, cockpit video, displays and flight instrumentation, radios, traffic collision avoidance systems, and weather radar, among other systems.

CoreAVI’s Vulkan-based VkCoreSC graphics and compute driver portfolio is based on a subset of Khronos’ Vulkan application programmable interface (API) open standard, and supports applications aligned to DO-178C DAL A. Vulkan can allow itself to receive either graphics or compute commands and allocate them to the correct execution unit in the graphics processing unit (GPU), and then render the result on the display.

Furthermore, the graphics and compute driver portfolio enable avionics developers to implement a full software stack on NXP’s i.MX8 and Intel’s 11th Gen Core i7 application processors.

Neil Stroud, VP of Marketing and Business Development at CoreAVI, commented on the new partnership with DDC-I, noting that avionics developers “targeting emerging SoCs like the i.MX8 and Intel’s 11th Gen Core i7 now have a versatile, high-performance GPU acceleration platform to develop highly converged mission and avionics processing solutions with an accelerated, low risk path to flight safety certification.”

DDC-I and CoreAVI provided a combined set of emailed statements to Avionics International in response to questions about the new partnership, including an explanation of why emerging SoCs like the i.MX8 and Intel’s 11th Gen Core i7 are ideal for developing new graphics-intensive avionics display applications.

“The avionics industry is driven to emerging SoCs such as NXP’s i.MX 8 or Intel’s 11th Gen Core i7 as these SoCs consolidate functions into smaller pieces of silicon for the A&D space. They combine the best of small form factor, performance levels, and power consumption, which allows integrators to use state-of-the-art technology while maintaining strict [size, weight, and power] SWaP requirements,” the representatives said. Printed circuit board (PCB) and system level space is also reduced when SoCs are used due to fewer and higher-density components, according to the two companies.

Further, aside from SWaP optimization, SoCs provide a standardization of processor, I/O, and interconnect targeted for application-specific embedded applications.

“This reduces the level of customization required and level of engineering effort needed to employ an SoC in an avionics system. That is, the hardware and software engineering effort and time to deploy these SoCs is generally lower than to do the same with multiple discrete IC components,” the representatives said. “This cost savings continues through to procurement and manufacturing where consolidating functions onto a single chip reduces the number of components purchased (generally at a lower cost for the SoC and compared to purchasing than multiple discrete ICs) and put into assembly (manufacturing overhead) of the avionics system.”

While neither DDC-I or CoreAVI were able to confirm any specific companies or avionics OEMS they’re providing the new platform for, they did provide a list of the types of companies they believe it could be ideal for.

These include avionics companies developing display or artificial intelligence-based systems. Systems they create include more advanced display and user interfaces, high compute applications such as “sense and avoid,” or AI-based systems determining flight management or various AI military applications, according to the two companies.

In an announcement this week, Electra.aero shared news of its acquisition of the company Airflow. Both companies have developed electric short take-off and landing (eSTOL) aircraft, and Airflow’s eSTOL business will now be consolidated into the Electra brand. Marc Ausman, co-founder and CEO of Airflow—now Chief Product Officer of Electra—believes that working together with Electra will be a much stronger approach for bringing their eSTOL aircraft to market. “We are combining the best of both worlds,” he told Avionics International in an interview, “taking the best of what each company has learned.” The most immediate objective for Electra is to fly a technology demonstrator within the next 12 months.

The teams from both Electra and Airflow had prior experience in developing electric aircraft and working for major aircraft OEMs. Based on that experience, Ausman explained, each company had independently determined that an eSTOL model was the optimal method for bringing electric propulsion to market.

The Electra brand now includes the teams from both Airflow and Electra, and an even larger combined order book—with letters of interest for about 800 aircraft, said Ausman. “Many of the folks from Airflow fill in gaps in the team at Electra,” and vice versa, he added.

Airflow’s existing partnerships offer potential opportunities for growth to Electra. In October 2021, Airflow began partnering with Plug Power, a leading hydrogen fuel cell company. In what Ausman describes as a long-term partnership, the collaborators “are actively developing the technology to bring hydrogen fuel cells and other hydrogen technology to smaller Part 23 aircraft. That helps move us towards our ultimate goal of sustainability.” A key point of consideration in this partnership is determining what the entire product family will look like in the future, he noted.

Another potential area for growth for Electra is moving to an adjacent market, such as the seaplane market. The eSTOL model is well-suited for this specific market, Ausman said. “We’re really thinking about ways that the aircraft can be used outside of traditional runways. We think we can grow significantly [in the seaplane market] and help our customers grow,” he explained.

At the end of last year, Airflow entered into a partnership with Tailwind Air to explore development of an amphibious seaplane powered by distributed electric propulsion. Tailwind’s current fleet, offering a scheduled seaplane service from New York to Boston Harbor, is currently made up of Cessna Caravan amphibious seaplanes.

Another one of Airflow’s existing partnerships is with the company Pipistrel, an electric airplane manufacturer. Pipistrel agreed to supply motors, motor controllers, and batteries for Airflow’s proof-of-concept aircraft, which was intended to be a modified version of an existing fixed-wing design.

Ausman told Avionics that the first launch will be a hybrid electric aircraft. The next generation will be hydrogen electric, “then ultimately, when batteries are good enough, we’ll have a pure battery electric aircraft.” Unless there are any major breakthroughs in the technology, he views battery development as a path of incremental improvements.

The eSTOL model itself will combine aspects from both Airflow’s and Electra’s development programs. Each company found success with certain types of customers, resulting in an order book that is very complementary, Ausman commented. The new Electra team will develop an aircraft with “the broadest market appeal for regional air mobility and urban air mobility.”

Electra hopes to fly a technology demonstrator as soon as possible—in the upcoming year, Ausman shared. Following that, they will work on the pre-production prototype aircraft. Both teams had very similar milestones in mind as they developed their eSTOL aircraft, he added, saying, “We’re combining efforts in terms of what we’ve learned and what customer needs are moving forward—to [achieve] those milestones and be able to fly as soon as we can.”

Electra announced an investment from Lockheed Martin at the beginning of this year to support Electra’s goal of flying a technology demonstrator. In February, the U.S. Air Force awarded Electra a Phase III Small Business Innovation Research (SBIR) contract as part of the Agility Prime program, following a $1.5 million investment from the USAF in 2021. In March of this year, the USAF also awarded Electra a Small Business Technology Transfer (STTR) Phase II contract in which Electra will collaborate with the Massachusetts Institute of Technology (MIT) for developing flight control systems to integrate into its eSTOL aircraft.
