阐述了圆翼随动机制的基本原理,研制了无人验证机,并进行了风洞实验研究。结果表明:可以绕其圆心自由转动的圆形机翼(简称“圆翼”)能随其两侧气动阻力的不平衡而转动,从而消除翼面上的侧滑效应。采用这种气动结构的飞机具有绕其立轴转动,在转弯时可实现机翼无倾斜的航向机动能力。圆翼相对其任一轴线都是对称的。当机头偏离航向线而发生侧滑时,与机身同轴的圆翼在气动阻力的作用下,向反方向转动,以新的纵轴对正航向,继续保持机翼的气动平衡。
The basic principle of round-wing follow-up mechanism is expounded, an unmanned verifier is developed and wind tunnel experiment is carried out. The results show that the circular wing (referred to as “round wing ”), which can freely rotate around the center of its circle, can rotate with the unbalance of the aerodynamic drag on both sides to eliminate the side slip effect on the airfoil. The aircraft with this aerodynamic structure has the ability to maneuver about its vertical axis without tilting the wing during cornering. The wings are symmetrical with respect to either axis. When the head deviates from the course line and the side slip occurs, the circular wing coaxial with the fuselage rotates in the opposite direction under the aerodynamic drag to align with the new longitudinal axis and maintain the aerodynamic balance of the wing.
