Transonic flowfields about transport and fighter aircraft are modeled using the thin-layer and slender-layer approximations to the unsteady compressible Reynolds-average Navier-Stokes equations. The equations are solved by an explicit multi-stage Runge-Kutta time-stepping method using a finite-volume formulation on body-conforming curvilinear grids. Convergence acceleration and vectorization enhance code efficiency. Microtasking allows effective use of all available processors on a Cray X/MP-48. Results are compared with experimental data for typical fighter and transport configurations.
