An aircraft for making vertical and short field takeoffs is powered by a bypass turbofan engine having a core turbojet and a bypass fan. For vertical takeoffs, the efflux from the bypass fan is deflected downward to create lift. Exhaust from the core turbojet is ducted to turbine driven lifting fans at remote locations to create supplemental lifting forces which also provide aircraft control and stability. For cruise, the bypass fan efflux is discharged aft until sufficient forward airspeed is attained that exhaust gas flow to the lifting fans may be shu...


A propulsion system for use in an aircraft for making vertical and short takeoffs and landings comprising: at least one gas turbine engine having a core turbojet, a bypass fan, and a turbojet exhaust gas conducting tailpipe; a plurality of lifting fans, each fan having spoiling means to selectively spoil lift; exhaust gas duct extending from said exhaust gas conducting tailpipe to each of said lifting fans for communicating turbojet exhaust gas from said turbojet to said lifting fans for powering said lifting fans; said exhaust gas duct being divided int...
