Semi-Analytical and Empirical Approaches to Aircraft Configuration Effects on Post-Stall Aerodynamics - Invited

Abstract

Loss-of-control due to aerodynamic stall continues to be the largest contributor to fatal civil aviation accidents. Improved ground-based simulator training for post-stall recovery training would therefore be of great benefit. Post-stall aerodynamic models of aircraft will be required to carry out meaningful post-stall traning. This study offers a way to develop a representative aerodynamic model that will capture the effect of aircraft configuration changes relative to a baseline model. In this document, first a literature review on the effects of aircraft configuration changes on stall aerodynamics is presented. Next, an overview of the basic methodology in carrying out the configuration changes is shown, followed by details on how some of the coefficients are generated. Lastly, a full scale example of the application of the method is provided. Results from the application of the proposed method shows good match with wind tunnel data.
