Abstract: An engine for creating a propulsive force includes turbomachinery for generating a flow of hot exhaust gases and an initial thrust force, an augmentor positioned aft of the turbomachinery, and a system for injecting an oxidizer, which preferably undergoes thermal decomposition, into the hot exhaust gases so as to significantly increase the thrust force generated by the engine. In a preferred embodiment of the present invention, the oxidizer comprises liquid high test peroxide.

Abstract: A short take-off and vertical landing (“STOVL”) aircraft has a conventional gas turbine engine that is selectively mechanically connected to a vertically-oriented lift fan by a drive shaft when the aircraft operates in a vertical flight mode. An engine control provides for rapid response attitude control of the aircraft when the pilot initiates desired changes in the attitude (i.e., pitch, roll and/or yaw) of the aircraft. The control achieves the rapid response by varying both the inlet guide vanes of the lift fan and the area of the engine nozzle. These variations result in a substantially constant low rotor speed, which facilitates the desired rapid attitude response and corresponding aircraft control.

Abstract: A short take-off and vertical landing (“STOVL”) aircraft has a conventional gas turbine engine that is selectively mechanically connected to a vertically-oriented lift fan by a drive shaft when the aircraft operates in a vertical flight mode. An engine control provides for rapid response thrust control of the lift fan and low rotor spool when the pilot initiates desired changes in thrust. The control achieves the rapid thrust response by varying the inlet guide vanes of the lift fan, together with selective fuel flow scheduling. These variations result in a substantially constant low rotor speed, which facilitates the desired rapid thrust response and corresponding aircraft control.
