Supersonic Green Machine by Nasa

This future aircraft design concept for supersonic flight over land comes from the team led by the Lockheed Martin Corporation. It is Nasa’s effort to fly a little greener in space, which of course they should.

The team’s simulation shows possibility for achieving overland flight by dramatically lowering the level of sonic booms through the use of an “inverted-V” engine-under wing configuration. Other revolutionary technologies help achieve range, payload and environmental goals.

This concept is one of two designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced supersonic cruise aircraft. The only thing, they will probably enter service in a 2030-2035 timeframe, so one might say that is fairly late.
