Asymptotic Expansion of the Kernel Function in Subsonic Unsteady Lifting Surface Theory
Asymptotic Expansion of the Kernel Function in Subsonic Unsteady Lifting Surface TheoryA computer oriented asymptotic expansion of a singular integral function is presented. The function dealt with appears in the kemel of the integral equation which is solved for pressure distributions of subsonic unsteady lifting surfaces. Values of the function can be accurately computed in a short time by using the present expansion.
