无冷却式发射动力系统的内弹道研究

Interior Ballistic Analysis for Non-Cooling Underwater Launched Missile

根据无冷却式发射动力系统的特点,将其工作过程划分为燃气发生器和发射筒两部分,建立了燃气发生器和发射筒工作过程的数学模型,并对其内弹道特性进行了研究,为研制新型动力发射系统提供参考依据和研究手段。通过对燃气发生器计算结果进行试验验证,证明了其可行性和计算精度。针对不同发射深度和装药量的工况进行数学仿真发现,无冷却式发射动力系统做功能力很强,导弹可以达到很高的出筒速度,实现大深度发射。同时,发射深度和装药量对无冷却式发射动力系统的内弹道性能影响很大。

Sections 1 through 3 of the full paper explain and evaluate our ballistic analysis mentioned in the title. Here we just give a briefing of sections 1 through without cooling, the working course was divided in 3. Based on the characteristics of underwater launched missile to two parts： gas generator and missile silo. The interior ballistic model was established and characteristics were researched, which we think can serve as useful reference for the de- velopment of missile system. Compared with the experimental results, the calculation precise （see Fig. 4）. The simulation results, presented in Figs. 5 through 12, and their the missile can be launched from great sea depth because of its very high velocity; （2） lant and launching depth affect the ballistic parameters greatly. ones of gas generator were analysis indicate that： （ 1 ） both the amount of propel-
