The effect of a pylon-mounted nacelle on the flutter behaviour of a wing-pylon-nacelle configuration

On the prediction of aerodynamic loads on oscillating wings in transonic flows

Possibilities to develop calculation methods for oscillating wings in transonic flow are discussed. Special attention is given to the question of linearisation. Recent NLR results of pressure measurements on an aerofoil with flap in transonic flow are analysed. Correlations are made between steady, quasi-steady and unsteady results. Shock motion...
