摘 要:将串列翼布局和地效翼布局应用在水陆两栖飞机研究中,提出一种新型气动布局——串列地效翼布局。综合利用串列翼气动布局的高效气动特性以及地效翼在起降过程中地面效应区内的强地效增升作用,提高飞机升力系数。通过CFD软件,基于有限体积方法研究了串列地效翼气动布局前后机翼的相对位置对气动特性的影响,并对比分析了水陆两栖飞机起降阶段地面效应区和非地面效应区的流场特性。研究结果表明,串列地效翼气动布局前后机翼的相对位置对气动特性影响较大,适当调整两机翼相对位置参数,同时利用地效翼在地效区内的地效增升作用,能有效提高升力系数,改善飞机在起降阶段的气动性能。In this paper, the tandem configuration and the ground-effect configuration were applied to the research of amphibian, and a new type of aerodynamic configuration, the tandem ground-effect wing configuration was proposed. In order to improve the lift coefficient of the aircraft, the high efficiency aerodynamic characteristics of the tandem wing and the strong ground effect lift characteristics of the ground effect wing in the ground effect zone during take-off and landing was comprehensively used. Through CFD software, based on the finite volume method, the influence of the relative position of the wings on the aerodynamic characteristics was studied, and the flow field characteristics of amphibious aircraft in the ground effect zone and non-ground effect zone were compared and analyzed. The research showed that the relative position of the two wings of the tandem wing aerodynamic configuration had a great influence on the aerodynamic characteristics of the aircraft. Adjusting the relative position parameters of the two wings appropriately and using the ground effect to increase effect of the ground-effect wing in the ground effect zone at the same time can effectively improve the lift coefficient of the aircraft and improve the aerodynamic performance of the aircraft during take-off and landing.
