A continuously adjustable thrust solid rocket motor and solid rocket

Abstract

The invention discloses a solid rocket engine with the continuous and adjustable thrust and a solid rocket. The solid rocket engine with the continuous and adjustable thrust comprises a fuel gas generation assembly, a combustion chamber and a tail jetting pipe which are sequentially connected; the fuel gas generation assembly comprises an oxygen-enriched fuel gas generator and an oxygen-deficientfuel gas generator; an oxygen-enriched containing cavity capable of containing an oxygen-enriched electrically-controlled solid propellant is arranged in the oxygen-enriched fuel gas generator, and the oxygen-enriched fuel gas generator is provided with an oxygen-enriched ablation circuit; an oxygen-deficient containing cavity capable of containing an oxygen-deficient electrically-controlled solidpropellant is arranged in the oxygen-deficient fuel gas generator, and the oxygen-deficient fuel gas generator is provided with an oxygen-deficient ablation circuit; and the oxygen-enriched fuel gasgenerator is provided with an oxygen-enriched controller capable of controlling the oxygen-enriched fuel gas flow, and the oxygen-deficient fuel gas generator is provided with an oxygen-deficient controller capable of controlling the oxygen-deficient fuel gas flow. Therefore, the problems that a traditional solid rocket engine is narrow in thrust adjusting range and high in technical difficulty and the problem that a liquid rocket engine supplying and adjusting system is complex can be solved.

Description

technical field [0001] The invention relates to the technical field of solid rocket motors, in particular to a continuously adjustable thrust solid rocket motor and a solid rocket. Background technique [0002] A solid rocket motor is a rocket motor fueled by a solid propellant. It mainly consists of combustion chamber casing, solid propellant charge and nozzle. The outstanding feature of solid rocket motor is its simple structure, few parts required, and generally no moving parts. The above features make the solid rocket motor highly reliable, easy to maintain and operate. Therefore, solid rocket motors are widely used in various missiles, and the trend of solidifying power systems of various tactical and strategic missiles is becoming more and more obvious. [0003] For existing solid or liquid rocket engines, the thrust of the engine is usually controlled by directly adjusting the flow. For rocket engines using solid fuel, the existing way to adjust the flow rate is u...
