针对采用折叠舵的机载导弹发射后,舵面从折叠到展开过程中不同展开角下外翼面的气动特性特别是折叠轴扭矩进行研究。主要分析了展开角、来流马赫数、侧滑角对外翼面气动力的影响。研究发现,随着展开角的增加,外翼面气动力以及折叠轴扭矩均有不同程度增加;马赫数对外翼面的力及扭矩影响不大;随着侧滑角增加,外翼面受力及扭矩逐渐增加,增量与展开角有直接关系。
針對採用摺疊舵的機載導彈髮射後,舵麵從摺疊到展開過程中不同展開角下外翼麵的氣動特性特彆是摺疊軸扭矩進行研究。主要分析瞭展開角、來流馬赫數、側滑角對外翼麵氣動力的影響。研究髮現,隨著展開角的增加,外翼麵氣動力以及摺疊軸扭矩均有不同程度增加;馬赫數對外翼麵的力及扭矩影響不大;隨著側滑角增加,外翼麵受力及扭矩逐漸增加,增量與展開角有直接關繫。

The aerodynamics of outer wing especially for twist moment in different unfolding angles is studied after the launch of airborne missile with folding rudder .The effects of unfolding angle , Mach numbers and sliding angle on aerodynamic force of outer wing are analyzed .The results show that , aero-dynamic force and twist moment are both increased in different degrees with the increasing of the unfolding angle, while the effect of Mach number on the both is not obvious , the aerodynamic force and twist mo-ment are both increased with the increasing of sliding angle , and the increment is directly relate to the un-folding angle .
