Theoretical Prediction of Airloads on Thin Delta Wings in Incompressible Flow,

Abstract

Two methods are developed for the prediction of aerodynamic loads on sharp-edged delta wings in incompressible flow. The first method is based on the application of the Polhamus' suction analogy to the potential flow solution which is obtained in this paper by a unique numerical lifting surface method developed at Texas A and M University. The second method is a direct extension of potential flow theory. The mathematical model is modified by introducing a vortex system to represent the leading edge separation. The strength of the separated vortices are adjusted by an empirical factor whose value is chosen in such a way that the total system gives the required lift.
