    • PROBLEM TO BE SOLVED: To provide a rotary wing for a helicopter provided with a vibration damping device with small aerodynamic power resistance and long operation life of a constitution part. SOLUTION: The rotary wing (1) for the helicopter has a hub (2) rotating around a first axis (A); a plurality of blades (3) projected from the hub (2) in a vertical direction (C) perpendicular to the first axis (A) and connected to the hub (2) so as to be movable around a second axis (B) perpendicular to the first axis (A) and the vertical direction (C); and a plurality of damping devices (4) arranged between the hub (2) and the blade (3) and damping the vibration of the helicopter. The damping device (4) has a plate member (20) having one side fixed to the hub (2) and the opposite side connected to the blade (3) by elastic means (28, 29). The plate member (20) has flexibility around a third axis (D) coaxial to the second axis (B) during motion of the blade (3). Thereby, the problem is solved. COPYRIGHT: (C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a safety mechanism designed to prevent failures, in a disc rotor system which allows partial or full retraction of rotor blades to allow a helicopter as a vertical takeoff or landing aircraft to convert to wing supported flight for high speed cruise.SOLUTION: A disc rotor retraction system includes a main blade spar 22 incorporating a hydraulic cylinder 54 and having a screw thread 34. A ball screw 24 is concentrically carried within the main blade spar and is operably connected to a ball nut 60 which has an outboard end connected to an intermediate spar 26 with a hydraulic piston received for reciprocation in the hydraulic cylinder. A first geared actuator engages the ball screw and a second geared actuator engages a main blade spar screw thread.

    • PROBLEM TO BE SOLVED: To provide the lightest and smallest posible damping device controlling vibrations due to lead-lag movement of a blade.
      SOLUTION: The rotor 3 for a helicopter includes a drive shaft 10 rotating around a first axis A, a hub 11 rotating angularly integrally with the drive shaft 10 around the first axis A, and at least two blades 12 projecting from the hub 11 on the opposite side to the first axis A and extending along a plurality of second axes B crosswise to the first axis A. Each blade 12 is movable with respect to the hub 11 and the other blade 12 around a third axis C crosswise to each second axis B. The rotor 3 has at least two dampers 40 for damping vibrations of each blade 12 around each third axis C. Those dampers have each first part 41 capable of moving around each third axis C integrally with each blade 12, and second portions 42; 46a, 46b elastically united to each first portion 41 and functionally united to each other.
