Integrated Computational/Experimental Approach to Unmanned Combat Air Vehicle Stability and Control Estimation

Abstract

A comprehensive research program designed to investigate the ability of computational methods to predict stability and control characteristics of a generic unmanned combat air vehicle has been undertaken. The integrated approach to simulating static and dynamic stability characteristics was performed by the NATO Research and Technology Organization Task Group AVT-161. The vehicle named Stability and Control CONfiguration (SACCON) was the subject of an intensive computational and experimental study. The stability characteristics of the vehicle were evaluated via a highly integrated approach, where computational fluid dynamics and experimental results were used in a parallel and collaborative fashion. The results show that computational methods have made great strides in predicting static and dynamic stability characteristics, but several key issues need to be resolved before efficient, affordable, and reliable predictions are available.
