襟缝翼可动翼面的随动加载方法研究

Study on Tracking Loading Method of Locomotory Wing for Flap and Slat

以襟缝翼运动机构作为研究对象,模拟飞机真实飞行状态。首先通过对机翼盒段模拟件的刚度施加,满足了襟缝翼的刚度支持条件;其次采用单点双作动筒随动加载方案,通过控制作动筒载荷施加的大小及方向,模拟完成了襟缝翼运动机构在起飞和着陆放、收襟缝翼时襟缝翼上的气动载荷的变化过程。试验结果显示:襟翼和缝翼的每个通道力载误差都小于5%,此种襟缝翼可动翼面随动加载方法是可行的、有效的。

The object of the study is the flap and slat motion mechanism. For simulating the real aircraft flight condition, firstly, it meted the boundary conditions for the flap and slat by pressurizing rigidly on the box specimen of wing; secondly, using the single-point dual-actuator loading scheme, the changes of aerodynamic loads on the flap and slat motion mechanism under launch and retrieval conditions during takeoff and landing were simulated, by controlling size and the direction of actuator applied load. The study result of the test and analysis shows ： the error of the flap and slat each channel wing loading is less than 5%.The tracking loading method of locomotory wing for flap and slat is feasible and effective.
