Structural Integrity of a Fighter Aircraft Undergoing Dynamic Combat Maneuvers

Abstract

Under this AFOSR grant, we have developed a parallel spectral/hp element fluid solver that: enables an accurate and fast resolution of the flow field, and is linked to an hp-FEM structural solver, which in turn enables a realistic representation of thin solid structures, e. g. wings. Specifically, the flow solver is NEKTAR, which we have developed and modified for LES type computations of compressible flows. The structural solver is StressCheck, which has also been initially developed under AFOSR support by Prof. B. Szabo and subsequently by Engineering Software Research & Development, Inc.
