Abstract: A shaft assembly includes a shaft with magnets surrounding the shaft, and thermal conducting disks coupled to the shaft, and coupled to two ends of the magnets.

Abstract: A system for lubricating a remote bearing in rotating machinery is disclosed. An aerator is coupled on an end of a shaft distally from a gearbox and on a far side of an obstruction coupled to the shaft. Oil is carried centrifugally along an inner diameter wall of the shaft while air is carried along a central axis of the shaft. The aerator may include an axial groove for receiving oil from the inner diameter wall of the shaft. The aerator may further include a radial passage for carrying air into the oil to provide a misted lubricant that may be provided into the remote bearing.

Abstract: A ducted ram air turbine may be used to drive a generator to provide power to an aircraft. The ducted ram air turbine may be used in a pod attached to the aircraft, where the pod is fully powered, cooled and lubricated by devices attached to the ram air turbine. A gearbox may be deployed to control the speed of the turbine for driving various pumps and the like. The speed of the turbine may be controlled by inlet and exit actuators driving inlet and exit doors.

Abstract: A fluid control system may comprise a pressurized fluid path; at least two sensors for determining a state of fluid within the main fluid path; an isolation valve; and fluid-filled connection paths between the main fluid path and each of the at least two sensors. The connection paths may comprise first sensing tubes connected between the main fluid path and the isolation valve; the isolation valve; and second sensing tubes connected between the isolation valve and the at least two sensors. Upon closure of the isolation valve, the connection paths may be interrupted so that the sensors may be isolated from the main fluid path and so that they may be removed from the system without a need to de-pressurize or drain the fluid from the main fluid path of the system.

Abstract: A fluid coupler for connecting two hydraulic appliances together without requiring flexible hoses is described. The fluid coupler enables fluid-tight connecting between fixed position components and allows for separating the hydraulic appliances without decoupling the coupler while maintaining fluid-tightness of both appliances after separation.

Abstract: A hydraulic power assembly is comprised of a hydraulic pump being attached to and powered by a ram air turbine. A strut is rotatably attached to an aircraft by having one end mounted on a trunion, and the hydraulic power assembly affixed to the other, distal end. Flexible hoses fluidly communicate the pump with a hydraulic interface located inside of the aircraft. The hydraulic interface fluidly communicates with the aircraft's hydraulic system. The hydraulic power assembly and the strut are normally stored within the fuselage of the aircraft and are deployable into an adjacent airstream in an emergency.
