Abstract
A lift rotor arrangement () for a VTOL aircraft (). The lift rotor arrangement () comprises: a fairing () mounted on a wing segment (); and first and second rotor blades () mounted on a first shaft () extending vertically from the fairing (). The first shaft () is movable between an extended position in which the first and second rotor blades () are vertically spaced above the wing segment () and are rotatable to provide vertical lift, and a retracted position in which the first and second rotor blades () are rotationally-fixed with the first rotor blade () stowed within the wing segment (). The blades () may be rotatable around an axis substantially perpendicular to the axis of the respective first shaft () so as to act as ailerons/elevons in the retracted position.
