This paper proves that the calculation precision of the outside flowfield of the WIG using nonlinear k-εturbulence model is higher than using standard k-εturbulence model by comparison with experimental daˉta.The calculation results of the outside flowfield and airfoil of the WIG are given.It is found out that lifting forces decrease with the flying altitude increasing by analyzing and comparing with the lifting forces of different heights.
