Aerion. The supersonic aircraft will reduce CO2 emissions by 40%
By 2023 the first flight should take place
The Aerion AS-2 supersonic business aircraft, still under development, according to what was declared by the company CEO Tom Vice -at New York today- would be able to be powered by synthetic biofuels, so as to allow the aircraft to have a lower environmental impact "reducing -explained Vice- CO2 emissions by 40% compared to current standards". An engine fueled almost exclusively with biofuels and with only a small percentage of kerosene would allow Aerion's aircraft to overcome one of the crucial points for the return of supersonic aircraft, also because the Concorde (withdrawn in 2003) was very polluting and consumed a huge amount of propellant to cover the Paris-New York and London-New York routes.
The other obstacle to overcome for Aerion -which has also received investments from Boeing (see AVIONEWS)- concerns noise pollution, because the engines that would push the AS-2 to Mach 1.4 should be powerful as well as "silent "as the current ones; but to remedy this, engineers are also working on aircraft aerodynamics. Vice's idea, however, is to have the supersonic passenger transport aircraft make the first flight by 2023 so that the FAA (Federal Aviation Administration) certification process can begin as soon as possible , necessary like the drafting of new standards for this sector by the ICAO (International Civil Aviation Organization).
