Abstract

The invention provides a modular solid-liquid mixing rocket engine for a ground test, and relates to the technical field of aerospace engines. The modular solid-liquid mixing rocket engine comprises an oxidizing agent liquid collecting module, an ignition module, a combustion chamber module, a rear sealing head module and a spray pipe module which are sequentially and detachably communicated. By the aid of detachable module design and a mechanical sealing connector with a uniform standard, different tests are performed only through a small quantity of module design and replacement, comparability between engine test data is improved, design of the modular solid-liquid mixing rocket engine is simplified, and ground test cost is reduced.

Description

technical field [0001] The invention relates to the technical field of aerospace engines, in particular to a modular solid-liquid hybrid rocket engine for ground testing. Background technique [0002] A solid-liquid hybrid rocket engine refers to an engine in which the combustion agent is solid and the oxidizer is liquid. In terms of performance, the specific impulse of solid-liquid hybrid rocket motors is higher than that of solid rocket motors, lower than that of high-energy liquid motors, comparable to storable liquid motors, and has the advantages of simple and compact structure. [0003] The existing experimental solid-liquid hybrid rocket engines lack uniform specification requirements and poor reusability, resulting in high test costs. Moreover, it is not conducive to the comparison of data from different experiments, and it is not conducive to the comparison of experimental values ​​with theoretical research and numerical simulation results.
