摘要
通过改变头部形状,利用旋转火箭发动机末端加速旋转来探索新型的旋转助推钻地弹。建立了旋转助推钻地弹作用混凝土试验平台,进行了试验研究,得到了作用过程中侵彻速度与弹丸转速和火箭发动机推力之间的经验关系式。结果表明,旋转火箭发动机在助推钻地弹上应用原理上可行;在喷喉倾角不变的前提下,侵彻速度随着火箭发动机推力和旋转速度增加而增加,且转速的影响更大。研究结果可为固体火箭发动机在钻地弹上的应用提供借鉴。
A new-type spin-boosted earth penetrating weapon（EPW） was investigated by changing the nose shap and introducing spin motors in the end to speed up the ratation.For experimental study of spin-boosted IPW effects,a new concert test stand was built.From the test results,an empirical relationship among penetrating speed,rotational rate of warhead and trust of rocket motor was derived.It is shown that application of spin motors to boosted IPW is feasible in principle;if the nozzle indination angle remain unchanging,the penetrating speed increases with the rocket motor thrust and the rotational rate of warhead,and the latter has relatively great effect on the penetrating speed.Such study results could provide reference for application of solid rocket motor to EPW.
