SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 2008 - IPC F02K9/97

Abstract RU 2341676 C1

FIELD: engines and pumps.

SUBSTANCE: solid-propellant engine incorporates channel-tubular charge rigidly attached to the housing, an appliance designed to compensate for the charge combustion surface increase and a nozzle. The aforesaid appliance represents the nozzle inner coat made from high-strength slow-combustion solid propellant. The combustion rate and coat thickness are selected so that provide for increase in the nozzle critical section during combustion, proportional to the charge combustion surface increase. The nozzle recessed part, critical section and funnel should preferably have various-combustion coats.

EFFECT: engine higher efficiency and decrease in specific thrust loss, simpler charge production and reduced passive engine weight.
