Abstract

Abstract

The purpose of this paper is to give a new research for the doublet elementary solution method to solve the problem of subsonic flow. A strong singular integral equation is produced. The definition and the calculating formula of the effective principle value of strong singular integral are given. From this integral equation, some numerical methods corresponding to whole continuous distribution of elementary solution can be deduced. This tpethod is applicable to calculate subsonic aerodynamic force.
