摘要:火箭炮由于发射的是带有发动机的火箭弹,利用反作用原理推动射弹前进,不需要普通火炮那样的笨重的身管和复杂的反后座装置,因此可以将十几个发射管联装在一起,通过点火在 极短的时间内发射出去,不但具有极大的火力突然性和大面积的杀伤破坏作用,而且能在敌人心理上造成极大的震撼和威慑作用。然而,火箭在常规发射时,燃气流冲击力是发射装置所承受的最大载荷,这一载荷会引起炮的微小变位,但大多在允许范围内且已有办法予以实时修正。但是,若采用弹射发射方式,则存在一个比燃气流冲击力大得多的后坐力,会导致摇架以上部分发生较大角度的振动和射角、射向发生大幅变位,甚至使炮的诸多结构的强度出现问题;因此,拟在炮的中部不作根本改动的前提下,本设计设法在摇架和发射箱之间设置反后坐装置以削减冲击力峰值,再配合自适应支腿将强冲击载荷导向地面使得发射中有良好的抗燃气流冲击和反后坐能力。60227

\Abstract: The rocket is due to launch a rocket engine with the use of projectiles push forward reaction principle, no ordinary gun barrel as bulky and complex anti backseat device, so it can be more than a dozen launch tube mounted together through the ignition in a very short period of time launch out, not only has great firepower sudden and destructive effects of a large area of destruction, but also the enemy caused great shock and psychological deterrent. However, conventional rocket launch, the gas flow impact force transmitting device is the maximum load, the load will cause slight deflection shot, but mostly within the allowable range and approaches which have real-time correction. However, if the use of catapult launch mode, there is a much greater impact than gas stream recoil will cause the cradle there is a greater angle than some vibration and angle, fired a substantial displacement occurs, and even many gun structural strength problems; therefore, to be in the middle of guns does not make fundamental changes to the premise of trying to be the cradle of the design and launch box between the recoil system to reduce the impact force peak, coupled with the strong adaptive outrigger impact load oriented so as to emit the ground has a good anti-shock and anti-gas stream recoil capability.

1.1 火箭炮的地位及作用
随着现代科学的技术的发展以及在军事指挥、兵器技术中的应用,使现代化的兵器技术成为现代战争的物质基础,它有以下特点:战争的突发性变大、武器的破坏毁伤里加强、军队的机动力大大的提高、对后方补给的依赖加强。
火箭炮的战术运用非常广泛,它不仅仅为陆军中的炮兵、装甲兵、炮兵、防化兵、工程兵、等完成杀伤、破甲、爆破布雷等战斗任务,还为空军的空对地、空对空作战和海军的对水下舰艇、水面潜艇及登陆和抗登陆作战发挥着重要的作用。它的弹种之多也是其它武器所不及的,除了有破甲弹、杀伤弹、爆破弹、烟幕弹以外,还有云爆弹、布雷弹、干扰火箭弹,而且同时还能发射干扰机和传感器,用来干扰敌方的雷达通讯设备与进行侦查等。火箭炮比火炮更适合于发射末端制导子弹,它不仅仅在技术上比火炮容易实现,火箭弹射程远,杀伤面大,这些都十分有利于对付敌方的坦克群。 火箭炮反后座装置总体设计摇架设计:http://www.youerw.com/jixie/lunwen_65630.html
