    Abstract: The vibration created by torque of a rotor of a helicopter and the like is dampened by fastening a baseplate having a pair of diametrically opposed shoulders to the housing of the transmission box whereto the rotor mast is mounted. Relatively to the fuselage of the helicopter, projections are fixed which are independent of the baseplate and extend in opposition to the shoulders to cooperate therewith for limiting the rotary movement of the baseplate. Between the shoulders and the projections, resilient members are interposed to absorb the compressive force of the rotary movement.

    Abstract: The invention relates to a rotor hub for rotary-wing aircraft, in which a hollow one-piece rotor hub-mast is provided at its upper end with lobes lying in planes parallel to the rotation axis of the rotor hub-mast, pairs of such lobes forming yokes for respectively receiving a flapping hinge-pin for the associated blade.

    Abstract: PURPOSE: To provide a light-weight, highly reliable gyrocraft rotor hub body wherein only centrifugal force of a blade operates as a load, and in addition, to provide the rotor hub body suitable for manufacturing with composite materials. CONSTITUTION: This gyrocraft rotor hub body 1 has a form wherein each blade is connected with the rotor hub body 1 by joint-connecting members. The gyrocraft rotor hub body 1 consists of two rings 7, 8 located in the plane, which cross at right angles with an axle line extending from a column to a rotor in parallel with each other. These two rings 7, 8 are provided across a thin wall having an opening part 10 which is larger enough to insert the joint in. Supporting points for fixing the joint are fixed by a fixing member supported by holes 12, 14 of the rings 7, 8. As a result, a hard brace is formed, which enables power transmission.

    Abstract: The gyroplane rotor hub, to which the blades are attached by pivots and couplings, has two flanges (7, 8) connected by a thin wall (9) and set at a distance from one another which is sufficient to contain the pivots. The wall (9) is cylindrical in shape with apertures (10) of sufficient size for the couplings to pass through. The two flanges have holes (12, 14) through them lying parallel to the axis of the hub and in line with the middle of the apertures (10) to receive the pivot pins. The connection between the hub and the rotor shaft is made via a thin base (4), truncated conical in shape, with its large end fixed to the inside of the lower flange (8), and its smaller end fixed to the top of the rotor shaft (3).

    Abstract: The invention provides an integrated hub-mast with a single piece tubular body which supports, by its hub body part (3), a reinforcing girdle (6) on each side of which openings (10, 11) are formed. For each blade of the rotor a retaining and pivoting member (13), formed preferably by a spherical stratified stop, is fixed to the girdle (6) and is retained in the hub body (3), and this member (13) is also fixed between the ends inside the hub body (3), of the lower (20) and upper (21) branches of a forked fastening part (19) connecting the blade to this member (13), these branches passing through the openings (10, 11) of a corresponding pair of openings. A heel (23) fixed under the lower branch (20) bears against a reciprocal ring (24) mounted on a support (29) in the hub-mast (1), which has external fastenings for coupling to resilient return and drag damping members of the blades.

    Abstract: The invention relates to a device for damping the vibrations of a rotary-wing aircraft rotor. An annular weight is disposed concentrically of the rotor axis. This weight is supported by at least three resiliently deformable elements such as helical springs, radially biased in directions distributed regularly around the rotor axis. The inner ends of the springs directly bear on a part extending the rotor shaft axially. Their outer ends directly bear on the annular weight so that the spring apply statically balanced centrifugal thrusts to the annular weight. The springs are so still that they support the annular weight without substantially bending.
