US Air Force develops "third stream" adaptive fighter engine

Edited US Air Force Research Laboratory video explaining its program to develop a new type of turbofan engine that changes cycle to combine high thrust for take-off and supersonic acceleration with fuel economy for cruise and subsonic loiter. General Electric and Rolls-Royce Liberty Works will ground-test ADVENT demonstrator engines in 2013, GE and Pratt & Whitney will do follow-on groiund demonstrations in 2016 under the AETD program. The engines designed under AETD could power the F-35 JSF after 2020 and any 2030-timeframe sixth-generation fighter the US may develop.

NO way!! I just sketched a design for exactly the same purpose last night..I can't believe this is already in development. My design incorporates Venturi Effects and Bernoulli's Principles as does the ADVENT. Convergent air into divergent airstream. Very impressive physics/engineering to say the least! lat'r Buzz

Sheesh! wondering if I should remove my comment or if there aren't any others with an opinion? lat'r Buzz
