Abstract [en]

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.
