通过对6种不同结构的柔性翼模型进行的变迎角、变风速风洞试验,研究对比了不同柔度的柔性翼的升阻特性以及对风速变化的响应特性。结果表明,微型飞机采用柔性翼虽然降低了机翼升力的产生,但能够明显改善升阻比;不同柔度的柔性翼会直接影响微型飞机对风速变化的敏感程度,当机翼结构和柔度经过设计后,可以显著提高微型飞机对风速变化的适应能力。试验数据和结论对提高微型飞机的升阻特性以及对风速变化的响应特性具有一定参考价值。
By varying the attack angles and changing wind tunnel tests on 6 different flexible wing models, the research on the drag-resistance characteristics of flexible wings with different flexibility and their response to wind speed changes were studied. The results show that although the flexible wing of miniature aircraft can reduce the lift of the wing, the lift-drag ratio can be obviously improved. The flexible wing of different flexibility will directly affect the sensitivity of the miniature aircraft to the variation of wind speed. When the wing structure and flexibility After design, it can significantly improve the adaptability of miniature aircraft to changes in wind speed. Experimental data and conclusions have some reference value to improve the lift resistance and the response to wind speed changes.
