초록

A solid propellant thrust control system, method, and apparatus for controlling combustion of solid propellants in an opposing grains solid propellant rocket engine (OGRE) is provided. In particular, an opposing grains rocket engine and propulsion system is provided, in which actuator means connected are connected to solid propellant grains disposed in the pressure vessel of the engine. The actuator means are operable to selectively move the solid propellant grains together or apart relative to one another, such that the burning ends of the solid propell...

청구항

What is claimed is: 1. A propulsion system, comprising:(a) a pressure vessel having an interior and exterior,(b) a rocket nozzle connected to the pressure vessel,(c) propellant slidably disposed within the interior of the pressure vessel, said propellant comprising at least two discrete solid propellant grains, each of said propellant grains having an end surface where combustion is initiated and occurs, said end surfaces opposing one another in an end-to-end spaced relation, thereby forming a gap between said end surfaces, said propellant grains being m...
