Abstract

PURPOSE: To enable the thrust force of an engine to be varied according to the necessity by allowing a rocket engine which stores solid propellant to be equipped with igniters which operate at a same time or at arbitrary separate times.
CONSTITUTION: A rocket engine stores plateau type double base propellant in a rocket chamber 1, and in two drilled holes on an end plate 4 which is applied with asbestos heatproof processing at the rear part of a combustion chamber 3, heatproof reinforced plastic plates 5 are embedded, and on said heatproof plates 5, two igniters 6 are fixed. Said igniter 6 can be ignited at a same time or at separate times by the conduction of ignit ion conductors 7, and thrust force can be varied. Combustion gas gushes from a nozzle 8, blowing off a nozzle closure 9.
