摘要： A module flexible ligament damper includes an cylindrical inner structure with a central axis and an outer cylindrical surface. An outer casing with an inner cylindrical surface is positioned around the inner structure. A modular ligament with an inner flange and an outer flange connected by a web is positioned between the inner structure and the casing. The inner flange is connected to the inner structure and the outer flange is connected to the casing to support the inner structure within the casing, and to permit free orbital movement of the inner structure on a plane perpendicular to the axis of the inner structure. In one embodiment, the web is straight but does not intersect the axis of the inner structure for flexing in a radial direction. In other embodiments, the web is curved for radial flexing.

摘要： A proprotor system operable for use on a tiltrotor aircraft having a helicopter flight mode and an airplane flight mode. The proprotor system includes a rotor hub and a plurality of proprotor blades coupled to the rotor hub such that each proprotor blade has three independent degrees of freedom relative to the rotor hub including blade pitch about a pitch change axis, blade flap about a flapping axis and lead-lag about a lead-lag axis. Each of a plurality of spherical bearings couples one of the proprotor blades with the rotor hub. In addition, each of a plurality of lead-lag dampers couples one of the proprotor blades with the rotor hub, wherein each lead-lag damper is aligned with the pitch change axis of the respective proprotor blade, thereby providing pitch independent lead-lag damping.

摘要： The disclosure relates to a rotary damper (1) for reducing and in particular braking a rotational or pivotal movement of a second component rotatable relative to a first component. The rotary damper (1) includes a first damper component (2), which is in particular fixedly connected or connectable to the first part, a second damper component (3), which is particular fixedly connected or connectable to the first second part, and a damping mechanism (4). The first damper component (2) is rotatable relative to the second damper component (3). In a first direction of rotation, a rotational movement of the first damper component (2) relative to the second damper component (3) is or can be braked due to the damping mechanism (4). According to the disclosure, it is provided in particular that the rotary damper (1) further includes a coupling mechanism (5), which is configured so as to operatively connect the second damper component (3) to the damping mechanism (4) upon a movement of the first damper component (2) relative to the second damper component (3) in the first direction of rotation, and, upon a movement of the first damper component (2) relative to the second damper component (3) in a second direction opposite the first direction of rotation, to release and/or prevent an operative connection between the second damper component (3) and the damping mechanism (4).

摘要： A damping connecting rod that can be converted into a rigid connecting rod in the case of abnormal vibrations. The damping connecting rod comprises a body having a cavity and a shaft inside the cavity, with a clevis associated with the body and allowing the clevis to be fixed to an element. The shaft can be longitudinally displaced inside the body or the body about the shaft. The connecting rod includes an arrangement for longitudinally immobilizing the shaft with respect to the clevis comprising at least one hook and at least one hollow, which are borne by two connecting rod pieces, respectively, which are configured to be displaced toward one another and with a shape such that, with the displacement of the pieces longitudinally with respect to one another, the hook driven into the corresponding hollow longitudinally immobilizes the shaft with respect to the clevis.

摘要： A torsional damper according to the present disclosure includes an inner sleeve and an outer sleeve. The inner sleeve is configured to couple with a shaft, arranged concentrically with an axis of rotation. The inner sleeve has a generally annular profile with a periphery and a male spline extending from the periphery. The outer sleeve is disposed about the inner sleeve, and arranged concentrically with the inner sleeve. The outer sleeve has a generally annular profile with a periphery and a female spline recessed within the periphery. The inner and outer sleeves are arranged with the male spline disposed within the female spline. The damper additionally includes a resilient coupler arranged between the male spline and the female spline. The damper further includes a ball disposed between the inner sleeve and the outer sleeve and configured to inhibit radial motion of the outer sleeve relative to the inner sleeve.

摘要： There is provided a translational inerter assembly for damping movement of a flight control surface of an aircraft with a support structure. The translational inerter assembly includes a press fit element rotatably disposed within the flight control surface. The translational inerter assembly further includes an inertia element disposed in the press fit element. The translational inerter assembly further includes a torsion bar coupled to the inertia element and to the support structure of the aircraft, such that when the flight control surface rotates, the inertia element translates, and movement of the flight control surface is dampened.

摘要： There is provided a translational inerter assembly for damping movement of a flight control surface of an aircraft. The assembly has a press fit element fixedly disposed within a first end of the flight control surface and rotatably movable with the flight control surface. The assembly further has an inertia element coupled to and installed in the press fit element. The assembly further has a torsion bar having a torsion bar first end coupled to and installed in the inertia element, and having a torsion bar second end fixedly attached to a support structure of the aircraft. Rotation of the flight control surface causes translational movement of the inertia element, via the press fit element, along a hinge axis of the flight control surface and along the torsion bar, resulting in the translational inerter assembly damping movement of the flight control surface.
