钨渗铜喷管在续航时沉积引起的内弹道重现性分析

Analyses of Internal Ballistic Reproducibility Caused by Sediment of Sustained SRM with Cpper-Sintered-Wolfram Nozzle

试验和理论分析了长时间续航发动机钨渗铜材料喷管由于沉积而引起的高、低 ,常温下内弹道重现性问题 ,针对该类发动机特点 ,提出了瞬时重现性和综合重现性的概念 ,并给出了评估其内弹道重现性的几个主要指标 。

Reproducibility of internal ballistics caused by sedimentary properties at natural ,low and high temperature of long-working-time sustained SRM with copper sintered wolfram nozzle is analyzed in this paper. The concepts of transient reproducibility and integrated reproducibility, and several prime indexes evaluating the degree of internal ballistic reproducibility are presented in consideration of properties of the kind of motors, which may present reference for design of similar motors
