Unstructured grid solutions to a wing/pylon/store configuration

The purpose of this article is to validate an inviscid flow solution package 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 experimental data are made for two freestream Mach numbers at five store locations relative to the wing. Both rigid body aerodynamics and mutual interference effects are explored. A very good agreement is observed between computed and wind-tunnel data.
