Aurora was a rumored mid-1980s American reconnaissance aircraft.There is no substantial evidence that it was ever built or flown and it has been termed a myth.. Boeing subsidiary Aurora Flight Sciences designed an electric VTOL prototype, developing it to prototype by 2019. Created by subsidiary Aurora Flight Sciences, a commercial version could enter service in the next five years. The objectives of Perseus B's ERAST flight tests have been to reach and maintain horizontal flight above altitudes of 60,000 feet and demonstrate the capability to fly missions lasting from 8 to 24 hours, depending on payload and altitude requirements. A piston engine, propeller-powered aircraft, Perseus was designed and built by Aurora Flight Sciences Corporation, Manassas, Virginia.
First, a model 1:10 was used to test the concept; it was flown with and without a fuselage. The U.S. government has consistently denied such an aircraft was ever built. Boeing Completes First Test of Autonomous eVTOL Air-Taxi Prototype. After a decade of development Aurora Flight Sciences has finally unveiled Odysseus, its full-scale, solar-powered, autonomous aircraft designed to stay in the air for months at a time. Last year, the agency published a report on the June 4 crash of the Passenger Air Vehicle developed by Boeing subsidiary Aurora Flight Sciences, which was attributed to resonant aircraft vibrations incorrectly activating the vehicle’s ground mode, commanding its motors to shut down. Further flight tests, with a 1:4 scale concept aircraft, were also conducted by Aurora.
Aurora, which will be a subsidiary under Boeing’s Engineering, Test and Technology division, will operate as an independent unit under the name Aurora Flight Sciences, A Boeing Company.
