摘要
本文分析了固体推进剂力学性能随温度变化的老化过程,提供了延伸率老化的可靠性模型和可靠寿命的计算方法.
The variation of mechanical properties of a solid-propellant in rocket motor with environmental temperature was analysed by means of probabilistic mechanics in the paper.A raliability calculation model of extensibility and a raliabile life calculation method were suggested.
