An airplane is provided. The airplane includes a compressing device. The compressing device includes a turbine with a first inlet and a second inlet. The turbine provides energy by expanding mediums. The first inlet is configured to receive a first medium of the mediums. The second inlet is configured to receive a second medium of the mediums. The compressing device includes a compressor and a motor. The compressor receives a first energy derived from the first and second mediums being expanded across the turbine during a first mode of the compressing device, receives a second energy derived from the first medium being expanded across the turbine during a second mode of the compressing device, and compresses the second medium in accordance with the first mode or the second mode. The motor provides a supplementary energy to the compressor

An air cycle machine is provided. The air cycle machine can be included an environmental control system of an aircraft. The air cycle machine can include a turbine comprising a plurality of inlet gas flow paths, a compressor driven by the turbine from a shaft, and a fan driven by the turbine from the shaft.

A system is provided. The system includes a first medium at a first pressure, a second medium at a second pressure, and a medium conditioning sub-system. The medium conditioning sub-system includes a compressor, a first heat exchanger, a second heat exchanger, and a turbine. The turbine receives the first medium and the second medium.

A runner assembly includes a runner with an aperture, a cradle, and a fastener. The cradle includes a planar base with an aperture, a tab extending from the base, and fingers extending from the base. The fastener extends through the apertures for attaching the runner to the cradle, and the fingers are adjacent to the runner and constrain the runner with respect to the cradle and the fastener.

The engine is adapted to generate thrust or designed to generate torque includes a combustor, the combustor generates an exhaust gas flow to push the rotor blades of a rotor in a rotor housing, the exhaust gas flow rotates the rotor, shaft, and fan which produces a rotating force and produces an air flow. The rotor housing having a first wall, a second wall, and a third wall which guides the exhaust gas flow until the exhaust gas flow reaches a housing gap at the second wall and the exhaust gas flow moves out from the rotor housing, while the first wall having another housing gap for the air flow to go through to cool the rotor and the cooling process adds torque to the engine. The engine includes an optional wind turbine assembly. An air compressor is either driven by an electric motor or driven by other means.

A cooling fan includes a boss section (12) connected to a rotary drive source, a plurality of blades (13) protruding outward from the boss section in a radial direction, and a cylindrical ring member (14) configured to annularly connect the vicinities of end sections outside in the radial direction of the plurality of blades. The plurality of blades (13) protruding outward from the boss section (12) in the radial direction are connected by the cylindrical ring member (14) in the vicinity of the end section outside in the radial direction. An air inlet groove (16) is formed at an end section in an axial direction of an air suction side of the ring member (14). The air inlet groove (16) is disposed between front regions in the rotation direction of all of the blades (13) on the ring member (14) and front regions in the rotation direction of the blades (13) adjacent thereto. The air flowing from the outer circumferential side passes through the air inlet groove (16) of the ring member (14) and gradually changes a direction to be suctioned between the blades (13).
