    摘要： The present subject matter relates to improved damping fluid mount devices, systems, and methods in which a damping fluid mount (100) includes an inner member (110), an elastomer section (130) that is affixed to an outer surface of the inner member (110), and a cup (200) containing viscous fluid (300). The elastomer section (130) has an outer diameter that is variable along an elastomer contour, and a crimped portion of the cup is radially crimped into the elastomer section (130) such that the crimped portion precompresses the elastomer section (130) and substantially mimics the elastomer contour.

    摘要： Vibration control systems, devices, and methods are provided for a rotary wing aircraft having a rotor including a plurality of blades (20) each attached to a hub (10) at its root end and capable of pitching with respect to the hub (10). The systems, devices, and methods include a blade pitch adjuster (100) that is passively adjustable in response to aerodynamic loading on the plurality of blades (20) to adjust a pitch of one of the plurality of blades (20) with respect to the hub (10) based on a frequency of the aerodynamic loading. The blade pitch adjusters (100) can be configured to exhibit relatively high stiffness at the rotor rotating frequency and tailored dynamics at frequencies higher than the rotor rotating frequency such that hub loads at one or more higher harmonics are reduced.
