飞机附近流场对航弹弹道的影响及修正方法——航弹投弹表编拟方法研究(二)

THE EFFECT OF FLOW FIELD NEARING AIRCRAFT ON TRAJEC TING OF BOMBS AND THE CORRECTING METHOD—The Study of Making Tables for Aircraft Bombs(Ⅱ)

飞机在空气中运动时使周围的空气产生一定的流动速度,而航空炸弹的弹道初始段正好在这一流场之中,因而扰动流场对航弹弹道将产生一定的影响.本文在分析扰动流场产生原因的基础上,提出了用等效弹射速度的方法修正扰动气流对弹道的影响,并描述了等效弹射速度的计算方法,最后从理论上分析了等效弹射速度与空气密度、飞机速度及俯冲角的关系。

A certain flow field is produced when an aircaft moves in the air.The initial part of bomb's flight is just in such an flow field, and a certain ef-fect of thc flow field on the bomb's trajectry will be formed. Based on ana-lysing the causing of the flow field, a equivalent ejecting velocity isdescribed, but also the relations to the velocity with respect to air density,the velocity of the aircraft, and dive angle are discussed. The method men-tioned here is one part of the making bombing tables.
