A skin design method of variable camber wing trailing edge
School of Mechanical Engineering, Northwestern Polytechnical University, Xi'an 710072, China
As an important part of the wing, the skin deformation accuracy directly affect the aerodynamic performance of the aircraft in different environments. Based on the idea of easy processing and easy deformation, a method for designing variable section thickness skin for trailing edge of variable camber wings is proposed. In this paper, firstly, the thickness and length of each segment of 3~8 segments of trailing edge skin are optimized. Then the deformation results of different segments of skin are compared and analyzed. Finally, the correctness of the design results and the effectiveness of the method are verified by using stacked skin experiment.
蒙皮作为机翼的重要组成部分, 其形变精度直接影响飞机在不同环境的气动性能。基于便于加工和易于形变的思想, 提出了一种用于变弯度机翼后缘的变截面厚度蒙皮设计方法。利用所提方法优化设计了3~8段机翼后缘上、下缘蒙皮的各段厚度和长度, 对不同分段蒙皮的变形结果进行了对比分析, 通过叠层蒙皮实验验证了设计结果的正确性及所提方法的有效性。
Key words: variable camber wing trailing edge / variable section thickness skin / upper and lower edge skin curvature
