摘要： 以有限体积法结合Standard kε湍流模型求解黏性不可压缩NavierStokes方程，采用滑移网格技术实现了串列翼前后翼间的相对运动，分析了前翼拍动后翼静止的串列翼系统的推进性能.探讨了衰减频率、拍动振幅以及前后翼间距对串列翼推进性能的影响.计算结果表明，串列翼的推力主要由前翼产生，且在一定的衰减频率和拍动振幅范围内，串列翼均较传统的单翼拍动具有更高的推进效率，同时，前后翼间距对串列翼推进性能影响不大.

Abstract: The propulsive performance of a tandem wing system that has a stationary trailing wing and a flapping leading wing was calculated. The viscous incompressible NavierStokes equations were solved by the finite volume method in conjunction with the Standard kε turbulence model. The sliding mesh method was adopted to achieve the relative motion between the leading wing and the trailing wing. The relationships between the reduced frequencies, flapping amplitude, and trailing distance with propulsive performance were investigated. The results show that the propulsive efficiency of tandem wing system is higher than single flapping wing in an appropriate reduced frequency and flapping amplitude region, and most of the thrust is produced by leading wing, the propulsive performance is minimal dependent on trailing distance.

Key words:  tandem wing, propulsive efficiency, sliding mesh, flapping wing
