| It is shown, that using the improved method of discrete vortices and Cauchy-Lagrange integral, it is possible to compute a field of pressure in area of a vorticity at presence rotating wing in it. The calculation formulas for cases of wing movement in unlimited and limited medium, and also at presence and absence of an external flow are obtained. Approbation of a method for cases of thin wing rotation (vorticity generator) in unlimited medium and close to the screen has shown, that it is very economic and allows with high degree of accuracy to compute fields with the large gradients of pressure coefficient. |
