水下高速翼展系统锁定能力仿真及试验研究

Locking Characteristic of the High-speed Folding Wing System Underwater Sinmulation and Test

水下高速翼展系统的锁定能力对于航行体的稳定性影响具有重要的意义,该文在水下高速翼展过程无法直接通过单纯的理论仿真及试验研究手段解决的情况下,采用仿真与试验结合的手段开展研究。通过地面试验修正水阻尼参数,摸索弹出翼锁定速度以及碰撞速度衰减系数,并考虑火工品驱动力、来流速度等各项偏差再通过仿真手段推断航行体高速航行时弹出翼的锁定以及反弹运动情况,得到了弹出翼能够被锁定,或没有被锁定也能及时保持展开到位的状态的结论。

The simulation and ground test were applied to analyzed the characteristic of the folding wing when deploying to the expected position for underwater high speed small vehicle.The results indicate that wing can be folded or remain being at the expected position if it can＇t be locked,and the stability requirement can be meeted.
