    • A dual series damper includes a fluid damper portion and a elastomeric damper portion. The fluid damper portion includes a first housing, a first connection member, and a piston coupled to the first connection member. The piston divides an interior of the first housing into a first fluid chamber and a second fluid chamber. The piston has a fluid passage in the piston, the fluid passage being configured to provide fluid communication between the first fluid chamber and the second fluid chamber. The elastomeric damper portion includes a second housing, a second connection member coupled to the second housing, and an elastomer between the first housing and the second housing. When a lead/lag force is introduced to the dual series damper, the fluid damper portion behaves rigidly so that the elastomeric damper portion dampens the lead/lag oscillation.
    • 双串联阻尼器包括流体阻尼器部分和弹性阻尼器部分。 流体阻尼器部分包括第一壳体,第一连接构件和联接到第一连接构件的活塞。 活塞将第一壳体的内部分成第一流体室和第二流体室。 活塞在活塞中具有流体通道,流体通道构造成在第一流体室和第二流体室之间提供流体连通。 弹性阻尼器部分包括第二壳体,联接到第二壳体的第二连接构件以及在第一壳体和第二壳体之间的弹性体。 当引导/滞后力被引入双重串联阻尼器时,流体阻尼器部分刚性地运动,使得弹性阻尼器部分阻尼引导/滞后振荡。

    • A lead-lag damper for a rotor assembly has a body mounted to either an inboard portion of a blade assembly or a fixed portion of the rotor assembly. A piston carried within the body is configured to allow for relative motion between the body and the piston. The piston defines opposing chambers within the body, the chambers being in fluid communication through a fluid passage. A link connects the piston to the other of the inboard portion of the blade assembly and the fixed portion of the rotor assembly, and the link engages a central portion of the piston. The piston acts on fluid in the chambers during relative motion between the piston and the body and causes fluid flow between the chambers through the fluid passage. Flow through the passage acts to damp lead-lag motion of the blade assembly relative to the fixed portion of the rotor assembly.
    • 用于转子组件的超前滞后阻尼器具有安装到叶片组件的内侧部分或转子组件的固定部分的主体。 承载在主体内的活塞构造成允许主体和活塞之间的相对运动。 活塞在体内限定相对的腔室,腔室通过流体通道流体连通。 连杆将活塞连接到叶片组件的内侧部分中的另一个和转子组件的固定部分,并且连杆接合活塞的中心部分。 在活塞和主体之间的相对运动期间,活塞作用在腔室中的流体上,并且通过流体通道引起腔室之间的流体流动。 通过通道的流动用于阻止叶片组件相对于转子组件的固定部分的牵引延迟运动。
