摘要: The present disclosure is directed to a rotor thrust balanced turbine engine (10) that may increase engine performance and efficiency while managing thrust mismatch or imbalance in a low pressure (LP) spool between a fan assembly and a turbine rotor assembly (20). The gas turbine engine (10) defines a radial direction, a longitudinal direction, and a circumferential direction, an upstream end (99) and a downstream end (98) along the longitudinal direction, and an axial centerline (15) extended along the longitudinal direction. The gas turbine engine (10) includes a turbine rotor assembly (20) and a turbine frame (30). The turbine rotor assembly (20) defines a first flowpath radius (11) and a second flowpath radius (12) each extended from the axial centerline (15). The first flowpath radius (11) is disposed at the upstream end (99) of the turbine rotor assembly (20), and wherein the second flowpath radius (12) is disposed at the downstream end (98) of the turbine rotor assembly (20). The turbine frame (30) and the turbine rotor assembly (20) together define a seal interface radius (25) inward of the turbine rotor assembly (20) along the radial direction and concentric to the axial centerline (15), and wherein the turbine rotor assembly (20) defines a ratio of the first flowpath radius (11) to the seal interface radius (25) less than or equal to approximately 1.79.

摘要: A diffuser assembly for a compressor is provided. The diffuser may include a first stationary wall and a second stationary wall coupled with one another and forming at least in part a volute configured to receive compressed process fluid from the diffuser. The second stationary wall may define a plurality of stationary wall grooves. The diffuser may also include a moveable wall defining a plurality of moveable wall grooves. The moveable wall may be disposed between the first stationary wall and the second stationary wall such that respective stationary wall grooves and moveable wall grooves form respective flow passages configured to receive the flow of process fluid exiting an impeller of the compressor. The diffuser assembly may also include an actuator assembly configured to displace the moveable wall to alter a cross-sectional area of each of the flow passages based on a flow rate of the process fluid.

摘要: An airplane is provided. The airplane includes a compressing device (109). The compressing device includes a turbine (113) 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 (109) includes a compressor (112) and a motor (117). 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 (117) provides a supplementary energy to the compressor.
