燃气流作用对车载箱式发射的动力学影响

The Dynamics Effects of Jet Flow on Missile Launching from Container

箱式导弹发射过程中,燃气流在发射箱上的作用对发射的动力学过程有重要影响。结合流场计算和发射动力学仿真,研究某型车载发射系统中燃气流对发射过程的影响。研究结果表明:导弹在发射箱导轨上运动过程中,燃气流作用加剧发射箱出口位置下沉,导弹离轨后,燃气流作用加剧发射箱出口位置回弹,对发射过程造成不利影响。

The effects of jet flow on launching container makes great influence on dynamics during missile launching. Making use of computational fluid dynamics method and dynamic simulation, the thesis studies the effects of jet flow on launch process of vehicular container-type missile. As a result, when missile moves along the guided rail of container, the jet flow effects expedite the descent of the container exit, however after missile leaves the guided rail, jet flow effects will expedite the container exit rebound. Both two instances make adverse effects on launching process.
