Abstract

This paper describes the efforts to model full three-dimensional unsteady loads due to aerodynamic, and engine exhaust effects for an AV-8B aircraft model. This study utilizes USM3D for baseline comparison, and a CREATE-AV product - Helios - to transition into an engineering prediction tool. The comparative advantages of the different aerodynamic load predict in codes involved, and the capability gaps to routinely predict engineering loads for buffet performance are also reported.
