火箭发动机喷流时产生的起始冲击波超压会使受冲击体发生破坏性的形变,这对火箭弹与载弹设备的相容性形成了不利的影响。弹体在新设备上进行搭载时必须考虑对起始冲击波超压的抑制以保护搭载设备不受破坏。采用电测技术和光学流场显示技术可以研究冲击波的作用情况。笔者就是在对冲击波超压实验研究的基础上,探索抑制起始冲击波超压以减小它对设备表面的危害的途径。通过在喷管尾设置抑制装置削弱了起始冲击波超压的峰值压力,改变了冲击波的形态,提高了火箭弹与其载体的相容性。笔者还对抑制的效果进行了分析
The initial shock wave overpressure generated during the rocket motor jet can cause damaging deformation of the impact body, which adversely affects the compatibility of the rocket with the equipment. When the projectile is mounted on a new device, it is necessary to consider the suppression of the overpressure of the initial shock wave to protect the mounted device from damage. The use of electrical measurement technology and optical flow field display technology can study the role of shock wave. Based on the experimental study of shock wave overpressure, the author explores the ways to suppress the overpressure of the initial shock wave to reduce its damage to the surface of the equipment. By setting the suppression device at the end of the nozzle weakened the peak pressure of the initial shock wave overpressure, changed the shape of the shock wave and improved the compatibility of the rocket with its carrier. The author also analyzed the effect of inhibition
