The aircraft, known as the AS2, would be the first supersonic civilian plane since Concorde flights were halted in 2003. Aerions efforts gained momentum when Airbus Group agreed in 2014 to help design and produce the plane, and a fractional-jet ownership company last year ordered 20. hop over to these guysAerion has considered two dozen engines from various manufacturers, including for civil and military aircraft. The choice is narrowing to a derivative of a civil aircraft power plant thats already in use, Miller said. He declined to say with whom Aerion is holding discussions. Supersonic travel isnt allowed over the U.S. and many other countries because of disruption from sonic booms, which occur when a craft exceeds the speed of sound.Aerion plans to operate the jet just below supersonic levels over land and increase velocity over the ocean to Mach 1.5, or 1.5 times the speed of sound. Initial fleet purchaser Flexjet, the fractional aircraft operator that announced an order for 20AS2s at last years business aviation conference, said it wasnt privy to the engine negotiations. Kenneth Ricci, principal of Flexjet owner Directional Aviation, said he hoped Aerion would announce an engine choice soon. According to an industry adage, time kills deals.
