UNSTRUCTURED GRID SOLUTIONS TO A WING PYLON/STORE CONFIGURATION/

The purpose of this article is to validate an inviscid now solution pa ckage based on a new unstructured grid methodology using experimental data on a wing/pylon/finned store configuration. The solution package consists of an advancing front grid generator, VGRID, and an efficient Euler equation solver, USM3D. Comparisons of computed data vs experim ental data are made for two freestream Mach numbers at five store loca tions relative to the wing. Both rigid body aerodynamics and mutual in terference effects are explored. A very good agreement is observed bet ween computed and wind-tunnel data.
