高超声速飞行器机翼关键部件损伤特性分析

分析了高超声速飞行器机翼关键部件的损伤演化及飞行器飞行动态对损伤的影响。在建立了高超声速飞行器机翼关键部件损伤动力学模型、飞行器动力学模型以及对机翼关键部件载荷应力分析的基础之上, 依次分析了飞行器飞行高度、速度、迎角以及控制舵面偏角等飞行器变量对机翼关键部件损伤动态特性的影响, 以确定影响损伤的关键变量。仿真结果表明, 相对于其他变量, 飞行器迎角对机翼关键部件损伤的影响是最大的。基于此结果可得出当飞行器进行高超声速飞行时, 从保证飞行安全与延长使用寿命的角度来看, 应尽量限制飞行迎角大小。所得结论为实际工程中结构可靠性设计提供了有价值的参考。

Abstract

Analysis is made to the damage evolution of the key component of hypersonic aircraft wing and the influence of flight dynamics on the damage.Based on establishment of damage dynamic model of the key components of hypersonic aircraft wing and dynamic model of hypersonic aircraft,and the loading stress analysis of the key components of wing,the effects of flight altitude,air speed,angle of attack and deflection of control surfaces on the dynamic damage characteristics of the key components of wing are studied respectively,thus to confirm the key aircraft variables having significant influence on the damage.The results show that the angle of attack has the most significant influence on the damage evolution of the key components of wing.From the safety and life extending perspectives,the angle of attack should be kept within a strict range while the aircraft is flying at hypersonic speed.The results can provide a valuable reference for the design of structure reliability.
