摘要:根据火箭弹对头体分离系统的要求，结合火箭弹的结构特点，提出了活塞式燃气分离方案，设计了分离形式和电缆线断线方法，并进行了分离系统的性能试验。试验结果表明：该分离系统工作可靠，分离形式和电缆线断线的设计合理，抛射组件未出现明显变形。通过试验，还获得了相对分离速度和火药药量的关系。该分离系统可用于弹径较小、壳体壁厚较薄，且相对分离速度要求较高的火箭弹进行头体分离。
Abstract:Aiming at stage separation requirement of rocket projectile as well as the characteristic of rocket, the piston-type separation device was presented. The separation form and cable-cut technique were researched, and the performance of the piston-type separator was tested. The results showed that the rocket projectile could be separated completely, the separation form and the cable-cut design were effective and the projected component had no evident deformation. The relationship of relative separation velocity and the mass of powder was obtained. The separation system can be used for the separation of rocket projectile with small calibre, thin shell and high relative separation velocity.
