采用柔性翼面的小型飞行器在通用航空器和特种飞行器领域得到了较广泛的应用。由于此类飞行器往往采用蒙皮为可变形柔性织物的高置上单翼以及推进式螺旋桨,其特殊的升阻特性、总体布局和动力影响使得其飞行动力学具有很大特殊性。结合气动力估算、风洞实验和飞行实验结果,在此类飞机的纵、横航向操纵性与稳定性方面得出了有别于传统飞机的一些结论,并给出了有关物理解释;提供了适合此类飞机的飞行动力学建模方法和一系列有别于传统飞机的设计参数取值范围。
Small aircraft with flexible airfoils have gained wide applications in the field of general aircraft and special aircraft. Due to the high lift monoplane and propeller with skin as deformable flexible fabric, the special lifting and dragging characteristics, overall layout and dynamic influence make the flight dynamics very special. Based on the aerodynamic estimation, the wind tunnel experiment and the flight experiment results, some conclusions are drawn from the conventional aircraft in terms of the maneuverability and stability of the aircraft in terms of longitudinal and transverse directions, and the relevant physical explanations are provided. A method of modeling aerodynamics for such aircraft, and a range of design parameters that differ from traditional aircraft.
