提高管状发射二级无控火箭射击精度的探讨

AN APPROACH TO IMPROVING THE FIRING ACCURACY OF THE TUBE-LAUNCHED TWO-STAGE UNCONTROLLED ROCKET

无控火箭的老大难问题是散布大,射击精度差。本文叙述采用无源控制变截面发射管、选择第二级火箭发动机的点火距离、对第二级发动机采用零推偏以及减少肩射时发射管的偏航和俯仰运动等技术,可大大提高既可肩射又可从固定的发射装置上发射的多管无控火箭的射击精度。

It has been a big and difficult problem that the uncontrolled rocket has large dispersion and low firing accuracy. By using the passive control, launching tube of variable cross-section, zero thrust misalignment of the second stage rocket engine, selecting the igniting distance of the second stage rocket engine and reducing the pitch and yaw motion of launch tube during shoulder firing, great improvement of firing accuracy can be achieved for both the shoulder and fixed launcher launched uncontrolled multitube rocket.
