补充资料:火箭增程弹
火箭增程弹 rocket-assisted projectile 弹丸尾部装有火箭发动机,用以增加弹丸射程的炮弹。其基本结构包括战斗部、火箭发动机、稳定装置和发射药等。发射时,它像普通炮弹一样开始在炮膛内运动;飞离炮口一定距离后,火箭发动机开始工作,提供推力,增大射程。火箭增程弹靠自身旋转稳定或靠尾翼稳定。前者称旋转式火箭增程弹,因弹长受稳定性要求的限制,火箭发动机较短,增程较小;后者称尾翼式火箭增程弹,其增程幅度较大,增程率通常约为25%~100%。 火箭增程弹的结构比较复杂,生产成本较高,采用增程措施占用了弹内的容积,相应减少了炸药装药量,使威力有所降低;射击密集度又低于普通炮弹,使其发展受到了一定的限制。 |
