某固体推进剂湿热老化模型

通过对常用失效物理模型的分析和总结,结合量子力学理论关于电子产品老化反应速率与环境温、湿度的关系,以推进剂力学性能参数为研究对象,建立了固体推进剂贮存使用寿命的湿热老化模型,并通过试验数据拟合得到具体的经验公式。该模型可作为湿热环境下固体火箭推进剂贮存使用寿命预估的理论依据,也可作为固体火箭发动机剩余寿命计算的参考模型。

Hygrothermal aging life model of a composite solid propellant

By studying and summing up the common failure physical models and combining with the quantum mechanics theory on the relationship between the electronic equipment aging reaction rate and tempreture-humidity,a hygrothermal aging life model for solid propellant storage and usage is established with the propellant mechanical properties as the research object. Further more,experiential formula was obtained by fitting experimental datum. The model can be used as a theory basefor the prediction ofthe storage life time span of solid rocket propellant under hygrothermal environment,or as a reference model for the calculation of the residual life of SRM.
