潜艇垂射导弹出筒姿态的研究

Numerical Solution for Outlet Attitude of the Missile Vertical Launched from a Submarine

导弹出筒姿态是影响全系统性能的重要因素。通过建立潜射导弹动力学模型,研究了艇速、适配器刚度等发射条件对潜载垂直发射导弹在横向流作用下的受力和出筒姿态参数的影响。数值解析结果表明,增大艇速会使导弹的承受载荷变大,出筒姿态恶化;提高适配器的刚度可以有效减小弹体出筒时的俯仰角度以及角速度。

The missile attitude when launching from tube is an important factor in whole system performance. A kinetic model was built to analyze the effect of lateral flow on the vertical launching missile from a submarine. The simplified model was a reduced scale, time-dependent, three-degree-of-freedom, motion equations for a rigid missile. The adapters were treated as equipotent distributing nonlinear rubber circle. How did the loads and motion parameters of submarine vertically launched missile under the lateral flow be affected by launching conditions such as submarine velocity, adapter rigidity was studied by establishing and solving the missile kinetic equations. The numerical result shows when the load become greater, the outlet attitude be terrible synchronously according to the greater submarine velocity; Elevation angle and angular can be reduced effectively by augmenting the adapter rigidity.
