The Flying Car Of the Future Looks to Flying Cars of the Past

The Air Force is close to testing an experimental vertical takeoff prototype under its new program.

The first contract in the U.S. Air Force's bid to acquire flying cars has gone to a company whose design harks back to a pioneer in the field.

California-based Sabrewing Aircraft Company received a $3.25 million Phase II Small Business Innovative Research earlier this month to test its Rhaegal-B, a four-rotor craft that the company says can carry up to 5,400 pounds up to 200 knots some 1,000 nautical miles.

With its four electric rotors, two on either side of the aircraft, the 60-foot Rhaegal-B somewhat resembles the M400X Skycar from Paul Moller.

Moller is, in many ways, the Nikola Tesla of the flying car field. In the early 2000s, the Moller International Skycar became the first non-helicopter vertical takeoff and landing aircraft to actually get off the ground. The four motors would lift the car up and then swivel to propel it forward, like a V-22 Osprey. Even though the design worked, it never made it into showrooms.

“For the engine, the most critical element is power,” Moller told The Futurist magazine in 2008.

“Once you reduce the diameter of the propulsion system [making the propellor smaller] you go from a helicopter to a fan system. So you're moving less air, and the less air you move, the more power it takes to generate a certain kind of thrust. If I took a helicopter and made it one-half the diameter, I would have to immediately add 60% more power. I halve the diameter again, I have to add 60% more power, again. The M400 Skycar has over 1,000 horsepower.”

Given the high cost to power it, the M400 Skycar was impractical for most locations outside of the Middle East, where oil sheiks would use them to traverse wide distances, Moller said at the time.

Sabrewing CEO Ed De Reyes, who once worked for Moller, said his former boss was restricted by the engines of his time. The best-suited for the purpose were Wankel rotor engines, and internal combustion engines, which offered high speeds but limited torque. The electric motors that have arrived in recent years are far more promising: smaller, lighter, yet capable of producing more torque than an internal combustion engine.

The Rhaegal-B design is highly but not fully autonomous, De Reyes said. A controller will command it from a ground station, but with the sort of low-effort, push-button interface you would encounter on a Northrop Grumman Global Hawk, rather than the more hands-on piloting needed for General Atomics MQ-9 Reapers.

Something else that's come a long way since the early 2000s is the ability to detect and avoid objects in mid-air. Ssense-and-avoidance systems are a major stepping stone to more widespread use of drones in U.S. civilian airspace. A lot of drone manufacturers are hoping for the FAA's blessing for their versions.

The Rhaegal-B combines radar and nine other sensors to give the aircraft a picture of the environment around it. It can take evasive action without any human control. (In fact, humans can't override it to accidentally steer the vehicle into something else.) If communication is cut off, it can continue to its destination with no additional imput from the ground operator.

The appeal for the Air Force has to do with versatility and even detectability. During a webcast on Monday, Air Force Col. Pete White, with Air Force Warfighting Integrating Capability, said that traditional helicopters are noisy compared new vertical-lift aircraft. Thanks, in part, to the new electric motors. “Within feet of an enemy, they can't hear you,” He said that new, nimble electric air vehicles that could take off and land without a runway could help the military “maneuver around the battlefield at a pace that would be impossible today”

The Air Force says it wants flying cars to evacuate wounded soldiers from the battlefield, among other missions. That means that they could be operating under fire. De Reyes says the military version of the aircraft has a Kevlar coating to protect it from small ballistics and can operate even when one of the motors is damaged.

Air Force officials have also said that they are looking to fund and support U.S. flying-car companies, lest they migrate to China or accept lots of foreign investment. De Reyes says he's often approached by Chinese investors looking to gain a foothold in his company and other entrepreneurs in this space are as well.

Sabrewing will test the Rhaegal-B at the Air Force's Edwards Air Force Base, hoping to meet safety requirements that will clear it for more military work and perhaps even commercial use. A June flight demonstration with its prototype has been postponed due to travel restrictions

France, UK strengthen military relations — but future fighter jet cooperation ‘not yet there’
By: Pierre Tran PARIS — British and French defense ministers will meet twice a year rather than just once, reflecting a deepening of bilateral relations despite Britain's impending exit from the European Union, said French Armed Forces Minister Florence Parly. “We have with the United Kingdom very close and deep relations in defense,” she told Defense News at a Sept. 6 event with AJPAE, an aeronautics and space journalists association. “That was formalized with the Lancaster House Treaty and will not be be called into question by the decision that the United Kingdom has taken to leave the European Union. “In defense, there is a shared determination to pursue and deepen this relationship.” The more frequent ministerial meetings reflected that intent. “This cooperation is precious and necessary for the security of the European continent,” she added. Britain has put at French disposal the much-needed Chinook heavy transport helicopter in the Sahel theater, reflecting a close operational cooperation and shared experience in overseas deployment, she noted. Britain has asked for what started as a technology demonstrator for a combat UAV to refocus toward a study of “technology areas,” she said. That left the door open for the technology to be applied for large programs, such as the Franco-German Future Combat Air System, she added. “The story is not yet written,” she said. “Perhaps in the next few years the British could be by our side on the FCAS project. But maybe I am just dreaming. We're not there yet.” The January meeting between French President Emmanuel Macron and British Prime Minister Theresa May, and their governments, also reflected close ties, particularly for the defense ministries, she said. That cross-channel summit closed without a pledge to build the demonstrator for a combat drone, disappointing French industry. France is the lead nation on the FCAS project, which aims to field a future fighter jet flying in a system of systems, linking up drones, tankers, future cruise missiles and swarms of drones. The departure of Britain from the EU, known as Brexit, is due to take place in March. https://www.defensenews.com/global/europe/2018/09/07/france-uk-strengthen-military-relations-but-future-fighter-jet-cooperation-not-yet-there

US defense department awards AirMap USD3.3m to develop AirBoss platform
US Department of Defense (DoD) has awarded Unmanned Traffic Management (UTM) service provider AirMap a USD3.3 million grant to to commercialize its AirBoss platform. AirBoss is an Intelligence Surveillance and Reconnaissance (ISR) software platform designed for Group 1 UAVs and developed together with Reveal Technology and the DoD's Defense Innovation Unit. The DoD recently announced USD13.4 million in Title III investments to support the domestic small unmanned aerial system (sUAS) industrial base and further enhance the US warfighter's situational awareness, improve human-machine teaming, and provide engineering support for aiding the integration of sUAS capabilities into DoD programs. Under this investment, AirMap received USD3.3 million to aid product development and engineering support for integration of sUAS mission planning, post-mission analysis, and unmanned traffic management software. The award coincides with the launch of the AirMap Defense Group (ADG), a defense and security business unit that provides mission-critical technologies to the DoD. AirMap is working closely with the Marine Corps Warfighting Lab to enhance and field test the AirBoss platform with small quadrotors. Airmap's AirBoss platform supports image mapping and analysis provided by Reveal Technology. Reveal's Farsight mobile application is a 2D/3D mapping and analytical tool for drone imagery, optimized to provide focused, intelligent analytics at the edge. The technology is used to provide intelligence for army squads. “UAS technology delivers critical situational awareness and tactical opportunities,” said Major Steven Norris, ACE Branch Head, Science and Technology, at the Marine Corps Warfighting Lab. “We look forward to further developing Unmanned Traffic Management (UTM) technology to enable safer and more efficient UAS operations teaming with personnel and manned aircraft.” “AirBoss equips troops with the tools to collect, process, share, and act on critical visual intelligence in real time,” said Garrett Smith, CEO Reveal Technology. “We are excited to work with AirMap and the DoD to develop a best-in-class platform for our warfighters. https://www.unmannedairspace.info/latest-news-and-information/us-defense-department-awards-airmap-usd3-3m-to-develop-airboss-platform/
