摘要： PURPOSE:To ensure smooth transmission of rotating force and load in such a structure that a hub plate with a rotor blade mounted thereon is fitted to a shaft with fittings by forming the plane portions to be adhered to the hub plate and the fittings, respectively, during fitting. CONSTITUTION:A composite material hub plate 3 with rotor blades 1 radially mounted thereon is fitted to a shaft with both upper and lower side fittings 10, 11. In this case, protrusions 15 are provided at four corners of both upper and lower side fittings 10, 11, respectively. The protrusions 15 has the plane portions 16, respectively, in parallel to the shaft. Time protrusions 15 are arranged to be adhered to the plane portions 17 of the hub plate 3. The respective plane portions 16 of the protrusions 15 are adhered to the plane portions 17 of the hub plate 3 and both upper and lower side fittings 10, 11 are fitted thereto so as to encircle the hub plate 3 with the protrusions 15. In this way, the torque of the shaft is transmitted as surface pressure via the respective plane portions 16, 17.

摘要： PURPOSE:To reduce structural weight of a blade because of decreasing a bending load applied to the blade during flight by providing a warp upward in a condition with no external force acting so as to eliminate necessity for limiting a wind speed at the time of starting and stopping. CONSTITUTION:A rotor blade 4 is given a warp upward as in a broken line 4a in a condition with no external force acting. A shape of this warp is formed symmetrical to a shape where the blade of no warp is warped downward by force of 1G relating to a horizontal line. That is, the blade is manufactured in a manner wherein curvature is increased in accordance with approaching a mounting part relating to a rotary shaft 6 and decreased in accordance with approaching a free end. As a result, when not rotated, the rotor blade is almost horizontally placed by its own weight as in a full line 4b. Further when applied a load by a gusty wind or the like, the blade hangs down in a condition 4c of two-dot chain line, but a hanging down amount is decreased by an upward warp amount. Since a vertical tail 3 can be moved to a two-dot chain line 3b, a total length of a fuselage can be shortened by this amount.

摘要： PURPOSE:To reduce the outside diameter dimension by arranging a lead lug damper between two beam-shaped parts which constitute the deflection part of a deflection member and accommodating a spherical bearing for connecting a pitch housing formed integrally with a rotary blade, with a hub, into the lead lug damper. CONSTITUTION:A deflection girder member 4 extending in the radial direction is shaped integrally with a hub body 2, and a flexible part 29 is installed on the outside in the radial direction of a leaf spring shaped part 3 at the inner edge part in the radial direction. The flexible part 29 consists of beam-shaped parts 8a and 8b which are arranged, keeping intervals in the revolution direction, and the edge part is formed integrally, and a deflection part 9 is formed outside. The leaf spring member 3 and the flexible part 29 are pin-joined, and a joint part 5 is joined compactly by combining a plurality of lug elements. An elastic metallic damper 7 is arranged between the beam-shaped parts 8a and 8b, and a spherical bearing 17 is built in the damper 7, and the pivot shaft 14 of a housing supporting member 13 is inserted, and the housing 10 formed integrally with a rotary blade 12 is fixed on the supporting member 13.

摘要： PROBLEM TO BE SOLVED: To provide a deicer of simple structure with a little power consumption, having excellent durability and applicable in a wide range. SOLUTION: A wing front edge part is provided with a metal plate exposed to the outside, and a coil inside. An alternating current is applied to the coil to heat the metal plate with ice stuck thereto, by induction heating. Deicing can thereby be performed efficiently, and power consumption required for deicing can be reduced. This deicer can be realized with simple constitution, and the coil can be provided in an airframe. Wiring constitution can be simplified, and wiring work is facilitated. The layout environment of the coil is excellent compared with the case of providing it outside of the airframe, so that high durability can be secured. A heating body can be formed of a member worn little by dust, to obtain high durability. Further, the heating body can be provided at a fixed wing, a rotating wing or a propeller, so that the deicer can be applied in a wide range.

摘要： PROBLEM TO BE SOLVED: To reduce the air resistance by turning a hub plate in the vertical direction without displacing it in the vertical direction. SOLUTION: Opposite two rotor blades 2a, 2b are rotated around a rotary shaft 3 of a rotor. These two rotor blades 2a, 2b are connected to each other by a hub plate 10. Since the centrifugal force applied to the rotor blades 2a, 2b is supported on the hub plate 10 and balanced with each other, it is not transmitted to other member. The hub plate 10 can be turned around two supporting parts 12a, 12b of an upper part of a rotor mast 11 within a flat surface, which includes the rotary shaft 3 of the rotor and a blade shaft, and rigidly supported so that it is not displaced in the vertical direction, the longitudinal direction and the twisting direction around the blade shaft. With this structure, air resistance is reduced so as to improve the economical efficiency.
