International Classification:

F01M 11/02

US Classification:

123196R, 123196 A, 123196 CP, 123196 AB, 123196 S, 123196 V, 1841041, 1841042, 184 18, 184 622, 184 621

Abstract:

Emergency lubrication systems and methods for an engine are provided. One system includes a primary lubrication system including a de-aeration oil tank configured to store de-aerated oil until the oil is de-aerated, a first oil supply line configured to provide de-aerated oil to the engine, and a first valve configured to control the flow of oil through the primary lubrication system. The system further includes a secondary lubrication system including a second valve coupled to the de-aeration oil tank and configured to control the flow of oil through the secondary lubrication system, and a second oil supply line coupled to the engine and to the de-aeration oil tank via the second valve. One method includes the steps of detecting a predetermined event in the engine, preventing the aerated oil from entering the primary lubrication system, and using the aerated oil in the secondary lubrication system to lubricate the engine.

US Classification:

123213, 123215

Abstract:

An axial vane rotary combustion engine includes various performance improving features. These features include fluid film bearings that enable the vane assemblies to react large loads, a dual vane assembly configuration that share vane loads over two cylindrical bearing supports, a vane actuation mechanism that provides positive actuation even with cam surface tolerance variations, and various features to reduce friction to thereby improve efficiency and reduce heat generation.

US Classification:

415230, 277500

Abstract:

Sealing apparatus and engine are provided. A sealing apparatus includes a first cover plate, a second cover plate spaced apart from the first cover plate, and a sealing element disposed between the first cover plate and the second cover plate and including at least two diaphragm members, wherein a first diaphragm member has a first stiffness and a second diaphragm member has a second stiffness that is different than the first stiffness. The sealing apparatus may be disposed in an engine.

International Classification:

F16C 32/06

US Classification:

384100

Abstract:

A hydrodynamic gas film bearing cooling gas control system includes a hydrodynamic gas film bearing, a supply conduit, and a flow control device. The supply conduit is in fluid communication with the hydrodynamic gas film bearing, is coupled to receive a flow of cooling gas from a cooling gas supply source, and is configured to supply the flow of cooling gas to the hydrodynamic gas film bearing. The flow control device is coupled to the supply conduit and is responsive to a physical characteristic of the cooling gas or ambient environment to move between at least two positions to thereby vary the flow of cooling gas, through the supply conduit, to the hydrodynamic gas film bearing.

Abstract:

Embodiments of a gas turbine engine including a lift-off finger seal are provided, as are embodiments of a lift-off finger seal and embodiments of a method for the manufacture thereof. In one embodiment, the gas turbine engine includes an engine housing having low and high pressure cavities, a shaft rotatably mounted in the engine housing, and a lift-off finger seal. The lift-off finger seal includes an finger seal backing spring and an aerodynamic foil. The aerodynamic foil extends around the outer circumference of the shaft and is configured to expand radially outward in response to aerodynamic forces generated during rotation of the shaft. The finger seal backing spring resiliently biases the aerodynamic foil toward the shaft, deflects to accommodate the outward radial expansion of the aerodynamic foil, and forms an annular seal around the aerodynamic foil to impede pressurized airflow from the high to low pressure zone.
