    摘要： A vibration isolator (10) for isolating the vibration of two bodies that are connected together is disclosed. The vibration isolator (10) comprises an inner cylinder (16) and a pair of outer housings (12, 14) concentrically bonded together with elastomer structures (18, 20) to form two chambers (22, 26) that are joined by a tuning port (24). The elastomer structures (18, 20) may serve both as the seals for the chambers (22, 26) and the compliant spring members in the isolator (10). The isolator (10) connects to a vibrating body by a spherical bearing (28). The chambers (22, 26) and tuning port (24) are filled with an inviscid fluid (34) and pressurized to prevent cavitation. In certain embodiments, pressure within the isolator (10) is maintained by a volume compensating device (30) connected to the chambers (22, 26) via a small diameter orifice (36).

    摘要： A pressure indicator according to the present invention monitors the pressure of the fluid in a vessel. One embodiment of the present invention comprises a closed pressurized gas volume behind a dimpled metal diaphragm. In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm overcomes the force of the gas pressure acting on the internal surface of the diaphragm to hold the diaphragm in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of the diaphragm will overcome the force of the fluid pressure acting on the external surface of the diaphragm, thereby moving the diaphragm into a convex geometry. A viewing window disposed in the side of the vessel can be used to view the pressure indicator and determine the shape of the indicator diaphragm.

    摘要： A rotary system including a grip having an opening forming a first bridge for receiving a centrifugal force bearing that faces inwardly towards the rotor mast. A rotor blade couples to the grip and a pitch horn positioned outside the opening pitches the rotor blade during flight. A bearing assembly attaches the first bridge to the yoke and controls blade forces exerted against the hub assembly during flight.

    摘要： A method of making a rotor yoke includes preparing a cured composite rotor yoke preform on a single-sided curing tool and machining at least one portion of the cured rotor yoke preform to form a rotor yoke. In one embodiment, preparing the cured composite rotor yoke is accomplished by applying successive layers of uncured polymeric composite material to a single-sided tool in a configuration to produce an uncured rotor yoke preform; disposing a semi-rigid caul to an untooled side of the uncured rotor yoke preform; enclosing the uncured rotor yoke preform and the semi-rigid caul by substantially hermetically sealing a vacuum bag to the tool; substantially evacuating a volume defined by the vacuum bag and the tool of air; and heating the uncured rotor yoke preform, sometimes under pressure, to form the cured composite rotor yoke preform.

    摘要： A system and method to adjustably create a reacting force in response to a vibrating force of a vibrating structure. The system includes an adjustable vibration absorber that creates a range of reacting forces. The method includes continuously monitoring the reacting force and the vibrating force with a sensor system operably associated with a control unit having an algorithm to determine if adjustment of the vibration absorber is required. If required, the control unit commands a driver to selectively adjust the vibration absorber such that the reacting force equals the vibrating force.
