The effects of aeroelastic deformation on the unaugmented stopped-rotor dynamics of an X-Wing aircraft [PDF]
A new design concept in the development of VTOL aircraft with high forward flight speed capability is that of the X-Wing, a stiff, bearingless helicopter rotor system which can be stopped in flight and the blades used as two forward-swept and two aft ...
