Embodiment Construction
[0025] The basic idea of the present invention is: a disturbance device for combustion stability appraisal test, that is, a disturbance device suitable for dynamic combustion stability appraisal of cryogenic liquid rocket The combined structure of the inner shell. It can not only meet the requirements of high and low temperature extreme working environment temperature, but also achieve reliable detonation in the range of 35K ~ 3600K. Among them, the disturbance device must first be subjected to a low-temperature and low-pressure environment (35K, 0.5MPa) for 3s before detonation, and then a high-temperature environment (3600K, 10MPa) for 5s, and the longest working time is about 10s. It can also meet the requirements of the vibration environment, and the structure will not be damaged under the comprehensive vibration acceleration of about 200g; at the same time, it is guaranteed that the explosion fragments will not cause damage to the inner wall of the copper alloy of the t...
