Abstract :
To solve the performance changing problem of icing wing of one aircraft, a test method of aerodynamic characteristics and structural characteristics based on flow field and structure field coupled analysis is proposed. The method is used to discretely analyze time-averaged N-S equation of two-dimensional steady incompressible viscous flow by finite element method, and solve droplet trajectory equation by 4-order ronggo-kuta method to determine the degree of pollution. Then coupled analyziz flow field and structure field, and compared with unpolluted wing´s aerodynamic characteristics and structural characteristics to determine the optimal position which improve icing wing performance. Practical similar experiment shows that the method can be applied to evaluate performance and optimum design of the icing wing.
