Development and Assessment of CFD Methods for Integrated Simulation of Air Vehicle Stability and Control

The Naval Air Systems Command (NAVAIR), NASA Langley Research Center, AS&M, and GDIT inc. have joined together in a cooperative effort to develop a computational modeling and simulation suite capable of handling air vehicle stability. The funding and computer resources were provided by the DoD High Performance Computing Modernization Office (HPCMO) under the Common High Performance Computing Software Support Initiative (CHSSI). This project is under Collaborative Simulation and Testing (CST) portfolio to provide scalable software for military application to reduce risk in weapons system development and to provide information to senior decision makers throughout the life cycle of the system. This paper summarizes the three year effort to develop a methodology to utilize CFD analysis for an improved test and evaluation process on fixed-wing air vehicle stability and control problems and to demonstrate an integrated analysis capability of airframe-inlet-compressor interaction for a high-performance military jet.
