A fluid-filled Active Vibration Absorber (AVA) (20) is described for attaching to, and controlling dynamic vibration of the member (22). The AVA (20) is comprised of primary tuning mass (23) preferably including an additional inertial tuning mass (26) which is associated with a primary resonant frequency (fn1), a flexible element (28) for interconnecting the primary mass (23) and, thus, interconnecting inertial tuning mass (26) to member (22), at least one, and preferably two, fluid chambers, (30) and (32), each having a defined volume stiffness Kv'1, Kv'2, a fluid (34) contained within the at least one and preferably two, fluid chambers, (30) and (32), a moveable piston (36) dynamically interacting with the fluid (34) in the at least one fluid chamber and preferably, in first and second fluid chambers, (30) and (32), to cause pressure variations which dynamically drive the primary tuning mass (23) within a range about the primary resonant frequency (fn1). Preferably, a coil (40) and magnet-and-pole assembly (38) driving the piston (36). The AVA (20) preferably includes a secondary resonance (fn2) which is tunable by adjusting the mass of the piston (36), volume stiffness Kv'1 of the first fluid chambers (30), and a piston area Ap1, amongst other parameters.

A method and apparatus is described for limiting transient motions between an aircraft power member and aircraft structure. The apparatus incorporates a coupler (20) for use with inertial-type mounts and includes a body portion (21) having a coupler piston (32) telescopically received therein. Upon exceeding a transient relative motion which causes a fluid flow velocity to be exceeded, seat (38) formed on coupler piston (32) interacts with lip (39) on body portion (21) to cause a fluid flow restriction. This method and apparatus restricts and limits transient motions, i. e. , acts as a snuffer, to limit further relative motion between an aircraft power member (54) and an aircraft structural member (52). The coupler piston (32) preferably includes a flexible seal (38) formed thereon and orifice (40) therethrough for providing additional throttle-type damping upon snubbing. This method and apparatus is particularly useful in inertial-type fluid mounts for mounting aircraft engines, fluid pylon isolators for helicopter pylon isolation, and Fluid Torque Restraint (FTR) systems for aircraft for limiting transient motions under certain conditions, such as during takeoff, landing, and maneuvers, yet providing isolation under normal operating conditions.

A fluid and elastomer damper includes a first and second members and an elastomer section flexibly mounting the second member to the first member and allowing lateral movement therebetween. The elastomer section includes an inner wall forming a portion of a cavity defined within the damper and a damping fluid disposed within the cavity. A flexible damping plate separates the cavity into first and second chambers. At least one passageway is formed between the damping plate and the inner wall, the passageway exhibiting a gap dimension between the wall and the damping plate. When lateral movement occurs between the first and second members, the gap dimension is maintained substantially constant by flexing of the damping plate along the lateral direction.

A fluid mount particularly suited for mounting an engine in an aircraft. The mount includes a frame which is fastened to the engine and a support movably mounted in the frame and adapted to receive a wing pylon stub shaft. Opposed liquid-filled chambers are provided on opposite sides of the stub shaft support and are fluidly interconnected by an elongate tube. An auxiliary chamber is provided on the frame adjacent to the upper liquid chamber and is divided internally into a gas-filled portion and a liquid-filled portion which is in communication with the upper liquid chamber via an orifice. The auxiliary chamber accommodates changes in liquid volume without adversely affecting either the static or dynamic performance of the mount.
