水下发射装置膛压测量方法探讨

Discussion on the Methods for Chamber Pressure Measurement of Underwater Launcher

由于水和空气介质的不同 ,使得水中膛压测量较空气中有显著的差异。对空气中常规测量膛压方法进行了分析比较 ,给出了一种适用于水下发射装置膛压测量的应变式测量系统的工作原理及组成 ,讨论水中动态压力测量中的管道效应问题 ,提出了水中压力动测的注意事项 。

Because of the differences between water and air, there will be obvious differences in chamber pressure measurement in these two mediums. The operation principle and composition of strain measuring system are given, which applies to measuring chamber pressure of underwater launcher in comparison with common measurement methods in the air. Pipe effect is discussed and which should be paid attention when underwater pressure dynamic measurement is brought up. A large amount of experimental results has proved the feasibility of this system.
