摘要
从气动角度,依据研究模型,运用典型条件,使用定性定量的方法对推力矢量燃气舵对导弹大攻角转弯和控制特性产生的影响进行了分析研究,指出推力矢量燃气舵控制对导弹的转弯速率贡献很大,燃气舵对超大攻角下的纵向控制和滚转控制等性能起着重要或决定性作用,以及在不同飞行条件和攻角下燃气舵对操纵力矩系数的贡献。根据对滚转控制的分析,指出了空空导弹选用燃气舵进行推力矢量控制的重要因素,及燃气舵对导弹性能带来的其他影响。
The influence of thrust vector jet vanes （TVJV） control on missile maneuver at high angles of attack and control characteristics is studied in aerodynamic view, using qualitative and quantitative methods on typical conditions. The result indicates that TVJV control has a significant effect on missile turn angular rate, longitudinal and roll control capability. The influence of jet vanes on control moment under different flight conditions and angles of attack is also indicated. The reason why air-to-air missiles use jet vanes to thrust vector control is shown according to roll control analysis. Other influences of jet vanes on missile capability are also discussed.
