摘要: <正> 大后掠机翼翼尖挂导弹对外界干扰的动力响应很灵敏,这种干扰主要来自随机不稳定气流或各种突加载荷。为保证安全和防止导弹失控,摸清其响应值非常必要;除理论计算外,对可能遇到的不平稳气流和突加载荷在翼尖导弹上的动力响应进行了空测,并用频谱分析和功率谱密度分析处理了空测数据,制订了翼尖导弹振动与冲击试验谱,进行了地面试验与空中打靶试验,获得了满意结果。

Abstract: Missiles suspended at highly sweptback wing tip are very sensitive to external interference, which often creates over-loading to the missiles. This case should be accounted for in the design of wing tip and its external stores. This paper introduces how the missiles response to wake, gust, unsteady airflow, landing collision, large indicated airspeed at low altitude, over loading, acrobatic flight, ceiling and big Mach number at level flight etc. and provides measured data and analyses monitoring results. These are probably valuable references for aircraft design.

Key words: highly sweptback wing, wing tip missile, dynamic re-sponse, data measured in the air
