    Abstract: A variable stiffness damper system including an inner spring positioned between a first wall and a second wall, in which the inner spring includes a first member and a second member each coupled together at a distal end by an inner bumper. The first member and the second member are each contoured toward one another. The first member, the second member, and the inner bumper form a cavity therebetween. An outer spring is positioned between the inner spring and the first wall or the second wall. The outer spring includes a spring arm contoured toward the inner spring. The outer spring includes an outer bumper positioned between the inner bumper and the first wall or the second wall. The inner bumper and the outer bumper are selectively couplable to one another based on a load applied to the damper system.

    Abstract: A check valve assembly for a supply pipe. The check valve assembly includes a hinge pin, a first flapper, and a second flapper. The first flapper is pivotally coupled to the second flapper with the hinge pin. The check valve assembly also includes a stopper located between the first flapper and the second flapper. The stopper is configured to limit movement of the first flapper and the second flapper. The check valve assembly further includes a plate assembly located downstream of the stopper. The plate assembly is configured to break vortices formed in a fluid flow across the first flapper and the second flapper.

    IPC: F01D25/16

    Abstract: A gas turbine engine includes a compressor section and a turbine section arranged in serial flow order. A shaft is provided rotatable with at least a portion of the compressor section and with at least a portion of the turbine section. A bearing is also provided supporting rotation of the shaft, with a support element in turn supporting the bearing. The gas turbine engine also includes a superelastic member formed of a shape memory alloy supporting at least one of the support element or the bearing. The superelastic member is installed in a pre-stressed condition to enhance a dampening function of the superelastic member.

    Abstract: A system for operating a turbo machine to maintain bearing engagement, the system including a bearing assembly; a first displacement device adjacent a bearing race; a second displacement device disposed adjacent the bearing race opposite of the first displacement device; an effort supply system disposed adjacent to the first and/or second displacement devices; and one or more controllers configured to perform operations. The operations include generating a first effort input at the first and/or second displacement devices; adjusting a thrust loading at the bearing assembly; generating a second effort input at the first displacement device greater than the first effort input; and displacing the bearing race opposite of the thrust loading at the bearing assembly via the generated second effort input at the first displacement device.

    Abstract: A turbine engine including a bearing element coupled to a rotor assembly and a bearing housing disposed substantially concentric to the axial centerline of the turbine engine. The bearing housing includes a first member coupled to the bearing element. The first member defines a groove at which a variable stiffness element is coupled to the first member and disposed within the groove. The bearing housing defines a first portion and a second portion adjacent to the first portion along a load direction. The first portion and the second portion together selectively define a gap therebetween based at least on a change in load along the load direction.
