ABSTRACT:
A system for enabling an aircraft to accomplish extremely short takeoffs and landings, which includes an integrated flight control system; a takeoff system; a landing system and a high thrust-to-weight propulsion system. The integrated flight propulsion control system includes a multi-axis thrust vectoring system. The takeoff system is operably engageable with the multi-axis thrust vectoring system. The takeoff system includes means for rotating the aircraft nose upwardly below stall speed without substantial use of thrust vectoring from the multi-axis thrust vectoring system. The landing system is operably engageable with the multi-axis thrust vectoring system. It includes means for de-rotating the aircraft from a high angle of attack to a main gear touchdown angle of attack sufficiently low to avoid scraping the tail of the aircraft. The high thrust-to-weight propulsion system is connected to the integrated flight propulsion control system for providing sufficient lift to support the aircraft at speeds below stall speed.
