Abstract : The importance of the estimation of flexibility effects on the maneuvering performance of an aircraft is known from the losses in lateral control and stability at high speeds. An aeroelastic parameter is introduced in a quasisteady analysis which separates the effects of Mach number from those of altitude on the lateral motion of a flexible wing. Its use is demonstrated by an application to a wing with one degree of freedom in roll and it is shown that the conventional stability derivatives can be modified to include the steady-state effects of flexibility. The determination of aileron reversal speed and applications for preliminary design are discussed. (Author)
