隐身榴弹表面吸波材料的抗压强度分析

Compressive strength analysis of RAM on stealthy projectile

在火炮发射隐身榴弹过程中,由于隐身榴弹的静不平衡、动不平衡,造成隐身榴弹在膛内运动过程中碰撞膛线,其表面涂敷的吸波材料将承受较大的接触力.发射过程中应保证不损伤吸波材料表面,确保吸波材料具有良好的吸波性能、不增加隐身榴弹的雷达散射截面.从理论上计算了隐身榴弹与膛线之间的接触力,为研制隐身榴弹用的抗压吸波材料提供了设计指标.

When the stealthy projectile is fired by artillery, it will impact the rifling while it is moving in the tube due to its static unbalance and dynamic unbalance. The RAM on the surface of the projectile will support a huge contact force. In order to keep the surface of RAM from being damaged, ensure the fine absorbing ability of the RAM, and not to increase the RCS of the projectile, the contact force between the rifling and the stealthy projectile was researched. The parameter for designing the RAM that can resist the contact force was proved.
