摘要
为更好地掌握机翼在地效区气动性能受各因数影响的变化情况,在拖曳水池开展了地效区机翼气动性能研究,分析了飞高、攻角和气垫对机翼气动性能的影响。结果表明,机翼以较小攻角近水面飞行可获得较大的气动升力和升阻比,而且随飞高的降低气动升力与升阻比逐渐增大,一定范围内随攻角的增加也逐渐增大,同时机翼低头力矩的变化与升力变化趋势相同,特别是有气垫作用下更加明显。
In order to grasp better the aerodynamic properties of wing in ground effect by various factor influence,in the towing tank the research for the aerodynamic properties of wing in ground effect is carried out,the effects of the flying height,flying angle and air-cushion on the aerodynamic characteristics of the wings are studied.The results show that the wing is closer to the surface of the water with a small angle,the greater aerodynamic lift and the lift drag ratio can be obtained,their values increased with the decrease of flying height,and in a certain extent their values increased with the increased angle,the momeng of the bow is same as aerodynamic lift,especially under the action of air cushion.
