摘要： One preferred embodiment of a rotary viscous damper that provides damping force constancy over the operating temperature range of a viscous working fluid includes a damper housing defining a stationary conical damping surface, a shaft member rotatably mounted in the damper housing, a rotor member having a rotating conical damping surface, a temperature compensation mechanism, and a bias spring. The stationary and rotating conical damping surfaces in opposed combination define the shear gap of the damper. The rotor member is mounted in combination with the shaft member, and is axially displaceable with respect thereto. The bias spring provides a constant spring force acting on the rotor member to axially position the rotor member to establish the baseline shear gap of the damper. The temperature compensation mechanism is mounted in compressive engagement with the rotor member and exerts a temperature-dependent biasing force thereagainst in opposition to the constant spring force. The temperature compensation mechanism includes a plurality of expansion elements mounted in combination with support sleeves. The expansion elements are formed from material having a high coefficient of thermal expansion and are operative, in response to temperature changes in the working fluid, to provide the temperature-dependent biasing force which causes axial displacement of the rotor member with respect to the shaft member. Axial displacement of the rotor member causes corresponding changes in the dimension of the shear gap to compensate for temperature-induced variations in the viscosity of the viscous working fluid to provide damping force constancy.

摘要： A swash plate assembly includes a rotationally stationary swash plate and rotational swash plate which rotates relative to the rotationally stationary swash plate through a bearing system. Each servo control rod is attached to the swash plate assembly to communicate control inputs thereto through a respective servo lug. Each servo lug defines a servo pivot point off an in-line plane inboard of the bearing system. As the servo lugs extend below the rotationally stationary swash plate, a relatively uncomplicated attachment arrangement is facilitated which provides for redundant locking features at a highly inspectable location which simplifies maintenance and increased safety. By locating the servo pivot point just inboard of the bearing system, an exceeding compact load path is defined thereby. The load path is defined from the servo control, to the servo lug, through the rotationally stationary swash plate, bearing system, the rotational swash plate, the rotor pitch control point and into the pitch control rod.

摘要： A rotor hub fairing system includes an upper hub fairing, a lower hub fairing and a shaft fairing therebetween. The rotor hub fairing system is attached to the counter-rotating, coaxial rotor system through a bearing arrangement such that the shaft fairing may be positioned at an azimuthal position about the main rotor axis of rotation relative the airframe by a de-rotation system. The de-rotation system controls the position of the shaft fairing about the axis of rotation such that the shaft fairing is prevented from rotating freely in unison with either shaft as may otherwise result during some flight regimes.
