Abstract
A rocket engine ( ) generates a flow of hot propulsion fluid through a nozzle ( N). Hybrid exhaust gas generators ( ) have their exhausts ( ) through the side of the nozzle. Each gas generator includes a fuel grain ( ) and a source of oxidizer ( ). The fuel grain is kept hot by either or both (a) direct radiation or conduction from the hot propulsion fluid, or (b) by a trickle of oxidizer. When the thrust vector is to be modified, the appropriate one of the hybrid gas generators receives a flow of oxidizer, and the resulting exhaust gas is injected through the side of the nozzle.
