Approximate computation of the cavitational flow around small span wings

The linearized problem of a completely cavitating wing of the small span is considered. The system of singular integral equations of a cavitating lifting surface is reduced to one-dimensional equations by using the Lawrence approximation. The method of discrete singularities is used for the numerical solution of this system. Dependences of the lift coefficient and the cavern length on the cavitation number are presented for rectangular wings for 0.254.Translated from Izvestiya Akademiya Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 4, pp. 166–170, July–August, 1973.
