Research on the Ageing Behavior of Composite Solid Propellant Grain under the Condition of High Temperature and High Humidity

摘要:

以模拟发动机的复合固体推进剂药柱为研究对象,进行了模拟热带海域高温高湿环境条件下其贮存老化的试验研究,分析了高温高湿条件下氮气密封体系中复合固体推进剂的老化机理,预估了该贮存及老化条件下复合固体推进剂药柱的寿命。

Abstract:

In this paper, some model motor’s composite solid propellant grain was treated as the object of study. The test of storage and ageing under the simulative condition of the tropic maritime space’s high temperature and high humidity was done. The ageing reason of composite solid propellant in the system airproofed by nitrogen under the condition of high temperature and high humidity was analyzed. The composite solid propellant grain’s service life under this storage and ageing condition was predicted.
