Device for combined blending reinforcement of solid rocket scramjet engine

Abstract

The invention discloses a solid rocket scramjet engine. The solid rocket scramjet engine comprises an isolated section and a combustion chamber, wherein the isolated section and the combustion chamberare front-and-rear connected. A plurality of spoiler devices are arranged side by side at intervals in the vertical direction on the left and right side walls in the combustion chamber. The interiorof the combustion chamber is divided into a plurality of gas flow passages in the direction parallel to the gas flow direction, and the upper and lower wall surfaces, corresponding to the position ofthe spoiler devices, in the combustion chamber are protruded outward to form an outwardly-protruding recessed cavity. The blending degree of air and gas in the solid rocket scramjet engine is enhanced, so that the air and the gas are fully contacted, the residence time of the primary gas in the combustion chamber is increased, the combustion efficiency of the primary gas is improved, and the overall performance of the solid rocket scramjet engine is improved.

Description

technical field [0001] The invention belongs to the technical field of binary solid rocket scramjet, and in particular relates to a device for combined enhanced mixing of solid rocket scramjet. Background technique [0002] The solid rocket scramjet uses the fuel-rich gas produced by the gas generator to mix and burn with air to produce high-temperature gas, which is then expanded by the nozzle to generate thrust. Compared with the liquid scramjet, it has the advantages of simple structure, low cost, short combat response time, good maneuverability and safety, and long storage time. Compared with the solid rocket scramjet, it has the advantages of easy flow adjustment and no Ignition and flame stability problems, the working process of the combustion chamber is less affected by the flow parameters, and the working time is long. Therefore, the solid rocket scramjet has a good application prospect. [0003] At present, the research on solid rocket scramjet is still in its inf...
