A seal assembly for a gas turbine engine includes first and second split-ring seals. The first split-ring seal includes circumferentially separated first and second ends, laterally separated first and second edges, a first sealing lobe adjacent the first edge, and a first integral clip portion adjacent the second edge. The first sealing lobe has a curved surface extending laterally outward from the first edge. The second split-ring seal is slidably received and nested in the first seal. The second split-ring seal includes circumferentially separated third and fourth ends and laterally separated third and fourth edges.

An exemplary fluid supply system for use on a turbomachine includes a turbomachine fluid container having a moveable barrier. A pressurized fluid is delivered to one side of the moveable barrier, and an opposing side of the flexible barrier communicates with a source of lubricant. Pressurized fluid is selectively delivered to the one side to move the moveable barrier between a flow-permitting position that permits flow from the source of lubricant to the turbomachine fluid container and a flow-restricting position that restricts flow from the source of lubricant to the turbomachine fluid container.

Non-interrupted turbomachine fluid supply

An assembly for holding a fluid includes an auxiliary reservoir inside a main reservoir. The auxiliary reservoir includes an auxiliary reservoir shell with a fill passage at or near its bottom. The auxiliary reservoir shell also has a vent passage at or near its top. The fill passage and the vent passage fluidically connect the auxiliary reservoir to the main reservoir. A fluid inlet is located inside the main reservoir and outside of the auxiliary reservoir. A fluid outlet located inside the auxiliary reservoir between the fill passage and the vent passage.

A lubrication system includes a control subsystem operable to selectively communicate lubricant from a reserve lubrication subsystem under a pressure to supplement lubricant from a main lubrication subsystem in response to identification of a prolonged reduced-G condition. A gas turbine engine includes a main lubrication subsystem in communication with a geared architecture; a reserve lubrication subsystem in communication with the geared architecture; and a control subsystem operable to selectively communicate lubricant from the reserve lubrication subsystem under a pressure in response to identification of a prolonged reduced-G condition. A method of reducing lubrication starvation from a lubrication system with a main lubrication subsystem and a reserve lubrication subsystem, the main lubrication system in communication with a geared architecture of a gas turbine engine, includes communicating lubricant under a pressure to the geared architecture in response to identifying of a prolonged reduced-G condition.

A lubrication system includes a control subsystem operable to selectively communicate lubricant under gas pressure from a pressurized reserve lubricant tank in response to a prolonged reduced-G condition.

A Snowboard Support System capable of relieving the load placed on the snowboarder's bound downhill foot and leg while riding on a chair lift. This invention is lightweight, compact, self retractable and safe. Most notably, the Snowboard Support System comprises a hooking mechanism that attaches to the chair lift, has an emergency releasable buckle, and an adjustment mechanism to change the length of the webbing to suit each snowboarder's height. The hooking mechanism is self retracted into an outer structure via a spring mechanism. The outer structure is fixed to the snowboard via U brackets and threaded inserts.
