An analysis of a new wing for the ECO1 general aviation aircraft. A new wing for this aircraft is hoped to provide better high-lift performance and a higher maximum angle of attack. To this end, using computational fluid dynamics with the SST k-ω turbulence model, this study explores modifying the wing profile and augmenting the wings with winglets, a feature not commonly used in general aviation. Using the CFD tool Fluent, two-dimensional simulations on variations of the Osquavia aerofoil indicate that both the slimmer and the elongated variants will provide for a greater maximum coefficient of lift and a higher stall angle. The three-dimensional CFD analysis predict that the winglets will decrease the overall drag in high lift-coefficient flight conditions without greatly penalising performance in the cruise condition. The addition of winglets are also shown to provide a higher angle of stall and improve flow across the control surfaces at high angles of attack.
