Abstract: A ram air fan has a fan impeller and a motor. The impeller and motor are mounted within a housing. An inlet header delivers air to an inlet for the fan. An air supply system delivers air from an internal cavity of the inlet header to the motor and air bearings. The air supply system includes a conduit extending through the housing. A connection from the conduit extends from a J-shaped tube mounted within the inlet header. The J-shaped tube extends to a remote end, with a perforated member positioned on the remote end.

Abstract: An air supply controller is configured to supply cooling air to an air cycle machine. The controller includes a chamber having a first inlet configured to receive air from a first source, a second inlet configured to receive air from a second source, and an outlet configured to pass air from first inlet and/or the second inlet to an air cycle machine. A control member is disposed within the chamber and configured to move from a first position to a second position. When the control member is in the first position it obstructs an airflow from the second inlet to the outlet and permits an airflow from the first inlet to the outlet. When the control member is in the second position it obstructs the airflow from the first inlet to the outlet and permits the airflow from the second inlet to the outlet.

Abstract: A cabin air compressor assembly that include a cabin air compressor disposed at a compressor inlet and a cabin air compressor motor operably connected to the cabin air compressor. At least one cooling flow inlet is configured to direct a cooling flow through various pathways in the cabin air compressor assembly, including across the cabin air compressor motor. A blower is configured to boost the cooling flow across the cabin air compressor motor, thereby increasing cooling flow provided to the air compressor motor. A static seal plate is downstream of the blower and guides the boosted cooling flow toward a cooling flow exit. In addition, the static seal plate isolates boosted cooling flow from a moving rotor of the cabin air compressor, and also forms part of a containment structure that contains fragments and breakage that may come from the cabin air compressor rotor.

Abstract: A turbine seal plate includes an inner rim with a labyrinth seal land that defines a central bore having a labyrinth seal diameter. The turbine seal plate also includes a housing coupling ring arranged radially outward of the inner rim. A housing pilot extends axially from the housing coupling ring and substantially parallel to the labyrinth seal land with respect to a radially inner portion of the housing pilot. The housing pilot has a housing pilot thickness, and a ratio of the housing pilot thickness to the labyrinth seal diameter is between 0.08 and 0.14. A frusto-conical body extends between the radially inner portion of the housing pilot and the inner rim of the turbine seal plate.
