LIFTING SURFACE IN TRANSONIC GAS FLOW,

Abstract

Lifting surface motion in the subsonic gas flow is studied. A method is developed for solving three-dimensional problems in a nonlinear approximation. The method is based on a concept of mapping of n-dimensional Euclidean space in a new space. The new space is selected in such a manner that its linear problem yields results which are accurate to terms of the second order of smallness along the perturbation parameter. The method makes it possible to study an extensive class of three-dimensional problems in the transonic region. In this work problems were studied for a symmetric, solid and thin wing in two and three-dimensional flows. The new results were obtained according to the dimensionless number in transonic flow.
