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.
Claims34
An engine for creating a propulsive force comprising:
- turbomachinery means for creating a flow of heated exhaust gases and an initial thrust force;
- an augmentor positioned aft of said turbomachinery means;
- and
- means for injecting an oxidizer into the flow of heated exhaust gases.
A method for generating an increased thrust force for propelling a vehicle comprises the steps of providing an engine having a turbomachinery stage and an augmentor having an interior portion;
- creating a flow of heated exhaust gases and an initial thrust force with said turbomachinery stage;
- injecting an oxidizer into the flow of heated exhaust gases so as to create an oxygen rich environment in said interior portion of said augmentor;
- and
- injecting fuel into said interior portion of said augmentor so as to increase said initial thrust force.
A vehicle having an engine for providing a propulsive force, said engine comprising turbomachinery means for creating a flow of heated exhaust gases and an initial thrust force, an augmentor positioned aft of said turbomachinery means, and means for injecting an oxidizer into the flow of heated exhaust gases.
