Calculation of Aerodynamic Forces and Performance Study on 2D Wing in Ground Effect

ZHANG Liang , CHEN Meng-meng , WU De-ming(Dept.of Naval Archit.& Ocean Eng.,Harbin Engineering University,Harbin 150001,China)  
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.
