战术弹道导弹头体分离问题研究

固体导弹低空头体分离的最大难题是反喷燃气流对来流流场的干扰。克服这个干扰的较好办法是增大分离速度,让其快速通过扰动区,使干扰引起的弹道偏差不致很大,本文从工程实践的角度出发,分析了头体分离对的各种受力,建立了数学模型。通过计算,给出了分离力、分离速度和碰撞冲量,为导弹设计提供了重要参数,具有工程实用价值。

ON NOSE-BODY SEPARATION OF THE TACTICAL BALLISTIC MISSILE

The most diffculty of the solid-propellant missile nose-boby Separation at low altitude comes from the disturbanoe of reverse nozzle combustion-gas flow to free flow field. In order to reduce ballistic errors which made by the.disturbance as far as possible, it is one of the best methods to increase nose-body separation speed, so as to pass warhea througb disturbacce field at high speed. In this paper, from the point of view of engincerong design, the various forccs at air frame in nc -body separating have been analyzed some mathematical model have been consstructed The separation forces and speed and the impact impuise are given by calculation, as reference in cngineering design.
