摘要： An aircraft power system includes an auxiliary power unit (APU), a transmission unit, and a generator. The APU is configured to output a first APU rotational power in response to determining a first condition and a second APU rotational power in response to a determining a second condition. The transmission unit is configured to receive the first APU rotational output power from the APU. The transmission unit outputs a transmission rotational power based on the first APU rotational output power and outputs the transmission rotational power based on the second APU rotational output power. The generator receives the transmission rotational power and produces an alternating current (AC) voltage having a target frequency based on the transmission rotational power.

摘要： A turbomachine dual spool transmission system can include a transmission assembly (600) configured to connect to a combination output (107) of a dual spool differential (100) at a transmission input (603) to be driven by the combination output to turn a transmission output (605). The transmission assembly can be configured to provide a first output gear ratio in a first state and a second output gear ratio in a second state. The system can include the dual spool differential (100). The dual spool differential can include a gear assembly (101) configured to combine a low pressure spool input and a high pressure spool input into a combination output to provide an output speed range smaller than a low pressure speed range alone.

摘要： A power extraction system (101) is provided and includes a low-pressure spool (116) of a gas turbine engine, the low-pressure spool being rotatable at an input rotational speed between a first minimum speed and a first maximum speed, downstream components (120) rotatable at an output rotational speed between a second minimum speed and a second maximum speed and a transmission assembly (130) by which rotations of the low-pressure spool at the input rotational speed are transmittable at the output rotational speed to the downstream components. The transmission assembly includes clutches (133) and a controller (135) configured to control openings and closings of the clutches according to an upshifting algorithm whereby a torque applied by the downstream components is used to reduce the output rotational speed to an output speed of a gear into which the transmission assembly is shifting.

摘要： A generator arrangement includes a stator (104) with armature winding (106), a rotor (108) with one or more permanent magnets (110) supported for rotation relative to the stator, a variable speed drive (112), and a control module (114). The variable speed drive is connected to the rotor for rotating the rotor within a predetermined speed range. The control module is disposed in communication with the armature windings and is operatively connected to the variable speed drive to maintain constant output voltage as load changes by varying rotational speed of the rotor.

摘要： A generator cooling assembly (101) is provided and includes a rotor (113), a generator assembly (130) and an air-cycle machine (ACM) (150). The generator assembly includes a generator housing (131), a generator (132) housed in the generator housing and a shaft (133) coupled to the rotor to transmit shaft power from the rotor to the generator to drive the generator. The ACM is housed in the generator housing and is receptive of air. The air is cooled by the ACM and output from the ACM to the generator as fully cooled air to cool the generator.

摘要： A generator arrangement (100) includes a housing (102) with a mounting feature (104), a main generator (106) with an outboard shaft (108) arranged within the housing and axially offset from the mounting feature along a rotation axis, and a permanent magnet generator (112). The permanent magnet generator has an inboard shaft (114) arranged within the housing between the main generator and the mounting feature. The outboard shaft is coupled to the inboard shaft to provide rotation to the main generator through the permanent magnet generator. Accessory gearboxes and methods of generating electrical power are also described.
