无伞双翼末敏弹翼片安装角对其稳态扫描作战指标的影响

为认清无伞末敏弹翼片安装角对其稳态扫描作战指标,如扫描角、扫描速率、扫描范围等的影响,通过四元数方法,建立了无伞双翼末敏弹的运动方程,对其稳态扫描阶段进行了数值仿真与分析。结果表明:相比于传统的欧拉法,四元数方法可避免数值仿真的退化,优化稳态扫描仿真结果;末敏弹翼片的安装角对扫描角、扫描速率、扫描间距有着重要影响;随着安装角的增大,扫描角和扫描间距逐渐增大,当扫描角过大时,末敏弹将出现失稳现象。该文研究有助于认清末敏弹的稳态扫描原理,对今后的工程试验具有重要的指导意义。

Influence of Double-win's Installation Angle on Performance During Stable Scanning Stage of Non-Parachute Terminal Sensitive Projectile

To study the influence of double-win's installation angle of terminal sensitive projectile ( TSP ) on the performance of stable scanning, e. g. the scanning angle, scanning frequency and scanning interval,the motion equation was established by quaternion algorithm, and then the stable scanning stage was numerically simulated. The result shows that the proposed quaternion algorithm can avoid the numerical degradation and optimize the stable scanning results compared with traditional Euler algorithm. The double-win' s installation angle significantly affects the scanning angle,scanning frequency,scanning interval. The scanning angle and scanning interval increase with the increase of installation angle,and the TSP will create unstability while the installation angle is too large. The proposed model is useful to understand the mechanism of stable scanning,and it provides a guideline for the general design of TSP.
