Relaxation methods for transonic flow about wing-cylinder combinations and lifting swept wings
A mixed elliptic-hyperbolic relaxation method has been applied to the study of a nonlinear small perturbation equation modeling steady, three-dimensional transonic flow. Certain nonlifting wing-body combinations were computed without difficulty, and a numerical procedure for treating lifting wings without bodies was presented. In an effort to simplify the treatment of swept and tapered wings with blunt leading edges, a coordinate transformation has been introduced to map the wing planform into a rectangle. Certain difficulties introduced by this transformation were explored, and results found from its use under valid circumstances were presented and compared with experiment.
