Solid-liquid hybrid rocket ramjet for test

Abstract

The invention discloses a solid-liquid hybrid rocket ramjet for test, which comprises a combustion chamber of a fuel gas generator, a spray pipe of the fuel gas generator, the head of a secondary combustion chamber, the body of the secondary combustion chamber and a tail spray pipe, wherein the combustion chamber of the fuel gas generator, the spray pipe of the fuel gas generator, the head of thesecondary combustion chamber, the body of the secondary combustion chamber and the tail spray pipe are sequentially connected with one another in series by a plurality of flanges; and the flange at the head of the combustion chamber of the fuel gas generator is fixedly connected with a thrust frame. The ramjet adopts an in-series detachable layout, so that each component and part can be conveniently detached and changed, the adjusting requirement of each parameter of the ramjet during test can be met, and the working condition under various structural parameter combination and various operating modes of the solid-liquid hybrid rocket ramjet can be conveniently simulated. A plurality of groups of important measure points are arranged and preset for the ramjet, so that each main parameter required by the test of the solid-liquid hybrid rocket ramjet can be directly or indirectly obtained.

Description

technical field [0001] The invention belongs to the field of aerospace propulsion, in particular to a novel solid-liquid rocket ramjet for testing. Background technique [0002] With the increasingly higher requirements for missile performance in modern warfare, it is difficult for traditional solid or liquid rocket motors to meet the needs of the new generation of air-launched missiles for off-zone launch and beyond-visual range under the constraints of missile mass, size and reaction time. attack requirements. Therefore, in recent decades, countries have turned their attention to the air-breathing engine-ramjet engine. Recently, the Russians proposed a new type of solid-liquid rocket / air-breathing combined engine, namely the solid-liquid rocket ramjet concept, which combines the respective advantages of solid and liquid ramjet engines and solves some problems encountered by pure solid or liquid ramjet engines . The combustion efficiency of this solid-liquid rocket ramje...
