Abstract : The goal of this research was to further develop zonal methods and three dimensional procedures for application of finite difference methods to solve complex aircraft configurations. For the task of three dimensional grid generation both elliptic and hyperbolic methods were developed. A chimera grid scheme, that is, the use of overset multiple grid systems, was also tested in two dimensions. In zonal methods several new algorithms were developed. These included combining transonic potential codes with thin layer Navier-Stokes equations, unsteady transonic potential, Euler and vector potential codes. This report summarizes the various numerical algorithms that were studied. (Author)
