摘要： A preferred embodiment of a pylon has six pylon mounting links for mounting the pylon to an airframe. Each link is considered “near-rigid” and has a spherical-bearing rod-end on both ends such that the link can only transmit axial loads. At least one of the links has a mass carried within the link and selectively moveable by an actuating means along the axis of the link in an oscillatory manner for attenuating vibrations traveling axially through the link. The actuating means may be an electromechanical, hydraulic, pneumatic, or piezoelectric system. By mounting each link in a selected orientation relative to the other links, the actuating means may be operated in a manner that attenuates axial vibration that would otherwise be transmitted through the link and into the airframe.
摘要翻译： 塔的优选实施例具有用于将吊架安装到机身上的六个安装链。 每个连杆被认为是“接近刚性”的，并且在两端具有球形轴承杆端，使得连杆只能传递轴向载荷。 链节中的至少一个具有在链节内承载的质量，并且可以通过致动装置沿着连杆的轴线以振荡方式选择性地移动，以便衰减轴向穿过连杆的振动。 致动装置可以是机电，液压，气动或压电系统。 通过将每个链节相对于其它连杆安装在选定的方向上，致动装置可以以衰减轴向振动的方式操作，否则轴向振动将通过连杆传递到机身中。

摘要： A torque coupling for a rotor head of a rotary-wing aircraft is configured for rotation with a mast and for causing rotation of an attached yoke. The coupling has trunnions that rotate with the mast and extend generally radially. Pad-bearing assemblies each have a central member coupled to one of the trunnions with a laminated spherical bearing and have laminated pad bearings affixed to opposing sides of the central member. The laminated bearings have alternating rigid and elastomeric layers. A bearing mount is affixed to each pad bearing and is connected to a yoke for rotating the yoke with the mast. The pad-bearing assemblies allow for relative motion between each central member and the associated trunnion and between each central member and the bearing mounts through elastic shear deformation, and this allows for gimballing of the attached yoke relative to the mast.

摘要： A vibration-isolatator utilizes a relatively small-diameter tuning port or passage and associated reduction in component size. In the illustrative embodiment described herein, a passive isolator is provided which includes a tuning passage or port which has a diameter which is approximately one-half the diameter of the prior-art isolators. The reduced radial dimension of the tuning passage of the isolator results in a remarkable decrease in its size and weight, thus increasing the efficiency of operation of the aircraft.

摘要： A tube form assembly includes an inner member and an outer member. Each of the inner and outer members has an offset which creates a cavity therebetween. During assembly of the tube form assembly, an adhesive is located in the cavity and squeezed out and through the adjacent bond lines between the inner member and outer member. The pressurization and flow of adhesive outward from the cavity facilitates removal of air bubbles, as well as prevents the introduction of air bubbles into the bond line.

摘要： A blade-pitch control system for controlling a pitch angle of blades on a rotor has an input swashplate assembly having non-rotating and rotating portions, the rotating portion being operably connected to blade grips. A feedback swashplate assembly has non-rotating and rotating portions, the rotating portion being connected to the yoke for movement with the yoke during flapping of the yoke. Linear actuators connect the non-rotating portion of the input swashplate assembly to the non-rotating portion of the feedback swashplate assembly. Motion of the yoke during flapping causes a corresponding motion of the feedback swashplate assembly and input swashplate assembly for providing selected pitch-flap coupling between flapping motion of the yoke and pitch motion of the grips.
