底排装置内弹道参数求解研究

STUDY OF INTERIOR BALLISTIC PARAMETERSRESOLUTION ON BASE BLEED UNIT

底排弹底排装置内的压力是底排内弹道的一个重要参数．原来求解底排装置内的压力所用的迭代式不收敛．本文对此作了证明，并给出了新的迭代公式，此式迭代收敛速度快，由此求得的底排参数与实验较吻合，对底排背景的进一步研究有重要价值．

Pressure in the base bleed unit of the base bleed projectile is a important parameter of base bleed interior ballistic. Iterative formula used in some papers to resolve the pressure in the base bleed unit is not convergent. Its convergence has been proved in this paper. A new iterative formula has geen given in this paper too. The convergent velocity of the formula is fast. The base bleed parameters resolved by the use of above formula coincides with experiment results. Which has important value for us further to study base bleed projectile.
