嵌银丝端燃药柱燃气发生器理论性能分析

为了研究嵌入金属丝后端燃药柱燃速的变化规律,探讨嵌金属丝端燃药柱燃气发生器应用于非壅塞固体火箭冲压发动机中的可行性。采用编制的零维内弹道程序,对嵌银丝端燃药柱燃气发生器的理论性能进行了分析。算例结果显示:嵌入银丝能有效提高推进剂的燃速;设计稳态段较长的内弹道曲线是嵌银丝端燃药柱燃气发生器应用于非壅塞固体火箭冲压发动机中的关键。

Theoretical Performance Analysis of End-burning Grain Gas Generator Embedded with Silver-wire

To investigate the law of burning-rate and the feasibility of application in unchecked sold ducted rocket,the performances of end-burning grain gas generator embedded with silver-wire were calculated by zero dimension interior ballistics computer program.Results show that the burning-rate of end-burning grain embedded with silver-wire would raise effectively.Furthermore,design of longtime steady part of interior ballistics curve is the key of applying silver-wire embedded end-burning grain gas generator to ...
