    Abstract: A transmission for a rotary-wing aircraft has a differential torque-splitting mechanism associated with an input shaft. The differential has a drive disk coaxial with the shaft and integral in rotation with the shaft, a first driven member coaxial with the shaft and generally adjacent the drive disk, and a second driven member coaxial with the shaft and generally adjacent the drive disk. At least one pin engages each of the drive disk, the first driven member, and the second driven member. The first driven member is configured to drive a first transfer gear, and the second driven member is configured to drive a second transfer gear for supplying torque to a bull gear associated with a rotor mast.

    Abstract: A tunable vibration isolator (451, 551, 651, 681, 691, 721, 801, 901, 973) with active tuning elements (473, 475, 573, 673, 675, 689, 705, 707, 745, 747, 747, 819a, 819b) having a housing which defines fluid chambers. A piston (455, 555, 655, 695, 725, 805, 970) is disposed within the housing. A vibration isolation fluid is disposed within the fluid chambers. A passage (463, 563, 663, 735, 881, 904) having a predetermined diameter extends through the piston to permit the vibration isolation fluid to flow from one fluid chamber to the other. The tunable vibration isolator may employ either a solid tuning mass approach or a liquid tuning mass approach. In either case, active tuning elements, or actuators, are disposed in the fluid chambers to selectively tune the vibration isolator.

    Abstract: 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.

    Abstract translation: 挂架的优选实施例具有六个挂架安装连杆，用于将挂架安装到机身上。 每条连杆都被认为是“接近刚性的”，并且在两端都有一个带有球面轴承的杆端，这样连杆只能传递轴向载荷。 至少一个连杆具有承载在连杆内的质量并且可以通过致动装置沿着连杆的轴线以摆动的方式选择性地移动，以衰减沿轴向行进通过连杆的振动。 致动装置可以是机电，液压，气动或压电系统。 通过将每个连杆相对于其他连杆以选定的方位安装，致动装置可以以衰减轴向振动的方式操作，否则该轴向振动将通过连杆传递到机身中。
