    Calculation method for the unsteady pressure field in the mixed potential-vortical region near a rotating wing (English)
    0 references
    The author investigates the pressure field in a vortical region with rotating wing on the basis of improved method of discrete vortices and Cauchy-Lagrange integral. Calculation formulas for wing motions in bounded and unbounded domains, and also in the presence or absence of an external flow are obtained. Approbation of the method for the cases of thin wing rotation (vorticity generator) in unbounded domains and close to a screen shows that the method is very economic and allows to compute fields with strong pressure gradients with high accuracy.
