低速旋转火箭弹飞行弹道偏流分析

Analysis on the Deflective Flow of the Flying Trajectory for the Low-speed Revolving Rocket

低速旋转火箭弹在飞行过程中,由于章动因素的影响产生偏流.本文根据外弹道学理论给出偏流的计算方法,并结合实例给出仿真模拟结果,通过计算分析偏流对多管火箭弹飞行轨迹的影响.

In the flying course of the low-speed revolving rocket,deflective flow willappear due to the nutation effect, the method of calculating the deflective flow based on the exterior ballistics is given, and the simulation result with some examples is also stated. Finally, analysis on the effect of the deflective flow on the flying trajectory of multiple-tubed rocket is carried out by computational method.
