火箭发动机装药温度测量

Measurement of Rocket Engine Charge Temperature

随着火箭弹射击距离的不断增长,其发动机装药温度测量精度对落点精度的影响日益突出。提出了测量火箭弹装药代用材料的方法来测量火箭弹装药温度,克服了火箭弹装药温度测量困难,提高了测量精度。介绍了装药温度特性曲线测量方法,通过试验选取代用材料,设计了火箭弹装药相似体及药温测量装置,并对结果进行了分析。

With the continuously increment of rocket projectile launching range, the influence from the measured accuracy of the engine charge temperature becomes increasingly evident for that of point of fall. This paper proposes the method to measure rocket projectile charge substitute material for measuring rocket projectile charge temperature, which overcomes the difficulty resulting from measuring rocket projectile charge temperal ure and improving the accuracy of measurement, presents how to measure charge temperature characteristics curve and how to select the substitute material through experiment. And analogue of rocket projectile charge and charge temperature measurement unit are introduced and the result is analyzed also.
