초록

The combustion of a hybrid engine is improved by continuously injecting into a precombustion chamber a hypergolic fluid such as triethyl aluminum which exothermically reacts with and vaporizes the oxidizer such as liquid oxygen. The prevaporized oxidizer evenly combusts the solid propellant grain to develop thrust.

청구항

A method of enhancing the combustion of a hybrid rocket comprising the steps of: injecting liquid oxidizer into the precombustion chamber of a hybrid rocket engine; adding to the injected oxidizer a second liquid exothermally reactive with the oxidizer in an amount sufficient to vaporize substantially all of said oxidizer within said chamber; exothermally reacting said oxidizer and liquid to form a gas containing vaporized oxidizer; flowing said gas adjacent the surface of a solid propellant grain; and reacting the oxidizer and surface of the grain to pr...
