The effect of an aerodynamically optimized winglet with trailing edge flap, on the flight characteristics was investigated, using the Rallye Morane aircraft. The static forces and moments, as well as the effect of the winglet on roll damping were determined in wind tunnel tests. The dynamic behavior and winglet action during spinning were determined during flight tests. The calculation of the dynamic behavior of the aircraft with tip strips or winglets is based on the measured static force and moment coefficients as well as on the estimated dynamic derivatives. The effect of the winglet on the coupling between longitudinal and lateral motion was calculated. Nonlinear effects for large angles of attack and sideslip angles were taken into account.
