Abstract
In work the approach to calculation of stationary aerodynamic characteristics of a thin wing with the account of its elastic deformations on supersonic speed of flight is considered. Statement of a problem with the generalized algorithm of its decision is given. Calculation models are considered: flow field about a wing (a space-marching method with MacCormack´s technique in the assumption of a inviscid continuous flow), the is intense-deformed condition of a wing. The choice of models is proved.
Results of work are aerodynamic characteristics of a typical wing of the high-speed aircraft with the account of its elasticity in comparison with corresponding aerodynamic characteristics of not elastic wing.
