摘要
针对大型民用飞机机翼所受2.5g机动载荷和极限突风载荷相对接近的情况,设计了三个控制方案利用飞机机翼外侧操纵面能同时减少飞机的机动载荷和突风载荷。采用了刚弹耦合的扰动方程对减载的效果进行了仿真和分析计算。仿真与计算表明,对于适航条款所要求的2.5g机动,离散突风和连续突风几种情况,三个方案均能减少飞机机翼所受的载荷。考虑到系统实现和减载效果,方案二相比于其他两个方案更具优势。
Three control sehemes were designed to reduce the maneuver load and gust load of the aircraft by using the outer control surfaces of the wing for tile large civil aircraft which suhjected to similar value of 2.5g maneuvering load and gust load. The effect of load alleviation is sinmlated and analyzed hy using the perturbation equation. Simulation and calculation show that three schemes can reduce the load on aircraft wing for 2.5g maneuver, disc, rete gust and continuous gust required by airworthiness regulations. Taking into account the system implementation and load alleviation effect,scheme two compared to the other two programs more advantages.
