Abstract
A flap support mechanism for attachment of a flap to a rotor blade so as to permit angular displacement with respect thereto has a tension-torsion member disposed coaxial with a hinge axis of the flap. One end at the blade root side of the tension-torsion member is secured to the rotor blade. The other end at the blade tip side of the tension-torsion member is secured to the flap. The tension-torsion member is placed such that it passes through a narrow cavity formed at the interior of the rotor blade. Such construction permits smooth flap motion in spite of a large centrifugal force.
