Numerical and experimental aerodynamic optimisation of two-seated light aircraft

This paper presents a numerical and experimental optimisation of the two-seated A S-2 aircraft. In the numerical part of study, geometrical modifications and the flow field analysis of some selected regions of the aircraft i.e. cockpit-wings, cockpit - rear part of the fuselage were performed. The wind tunnel experiments of initial and modified versions of the aircraft model were made, too. The balance measurements and tufts flow visualisation was conducted as well.
