    摘要: An airplane is provided. The airplane includes a pressurized volume and an air conditioning system. The air conditioning system includes a compressor configured to receive a flow of a first medium, a turbine downstream of the compressor in a flow path of the first medium, a first valve that diverts the flow of the first medium around the turbine, a second valve that provides a second medium to the turbine, and a third valve downstream of the turbine that directs an outlet flow of the turbine towards the pressurized volume and that directs the outlet flow of the turbine away from the pressurized volume.

    摘要: A fan rotor blade extending radially from a hub is described. The fan rotor blade may include first surface and a second surface, where the first surface and second surfaces are respectively defined by a set of X-coordinates, Y-coordinates and Z-coordinates. The X, Y and Z coordinates can be set out in any of Tables T-1, T-2, E-1, and E-2. The X, Y, and Z-coordinates can also be scaled by a predetermined factor, with the X-coordinates are oriented in a tangential direction, the Z-coordinates are oriented in an axial direction, and the Y-coordinates are oriented in a radial direction.
