Dynamic Stability Analysis of High-Lift Devices: A Computational Approach

About Course

Abstract:

This research aims to find the fundamental effects of high lift devices on the stability characteristics of a high-lift airfoil through computational fluid dynamics. Stability derivatives are calculated for four configurations: clean, slat deployed, flap deployed, and slat and flap deployed configuration. The static and dynamic coefficients are calculated by using the forced oscillation technique. Simulations are performed at various angles of attack and keep the oscillation amplitude and frequency constant. This approach enabled the efficient and accurate computation of stability derivatives. The results indicate an improvement in static stability characteristics; however, the dynamic stability deteriorates with the deployment of high-lift devices.
