4.6 质量平衡抛射和火箭增程技术相结合的发射原理 利用平衡抛射发射原理使火箭弹获得一定初速,在火箭弹距筒口一定距离处,火箭弹发动机点火,使火箭弹飞行速度进一步增大。质量平衡抛射和火箭增程技术相结合的发射原理又分敞开式平衡抛射和封闭式平衡抛射两种方式。具有代 4.6 The combination of mass balance projection and rocket firing range launch principle The use of balanced projectile launch principle to obtain a certain initial velocity of rocket launchers in a certain distance from the rocket launcher at a certain distance, the rocket engine ignition, rocket projectile flight speed further increased. The principle of mass emission combined with mass balance projection and rocket extended range technique is divided into two types: open balance projection and closed balance projection.
