摘要
本文基于势流边界元理论(BEM)和边界层动量积分关系式数值求解二维地效翼的气动力 ,研究了升力正负地效问题及粘性对地效翼升力、俯仰力矩及焦点的影响 。
In this paper,the aerodynamic characteristics of a two-dimensional wing in ground(WIG)are calculated numerically based on potential boundary element method and viscous boundary layer integral relation.The positive-and negative-lifting phenomena due to the ground and the effect of the viscosity on lifting force,pitching moment and dynamic focus are investigated.The numerical results for different boundary conditions of ground and a viscosity-corrected method are also presented.
