摘要： An air cycle machine includes a turbine section (22), a compressor section (18), and an axial flux magnetic gear system electromechanically coupling the turbine section to the compressor section. The axial flux magnetic gear system includes a stator (130), two rotors (126, 128), a winding system (214), and a control module (216). The stator includes stator pole sections (140n, 140s) and is oriented about a stator axis. Each rotor includes magnets (132n, 132s, 136n, 136s) arranged radially about a rotational axis which is aligned with the stator axis. Each rotor interacts with the stator such that the rotor rotates at a rotational speed when the axial flux magnetic gear system is exposed to an electrical current. The winding system stabilizes the position of the rotors along their rotational axes. The control module is configured to supply the electrical current to at least one of the winding system, the stator, and the rotors to drive rotation of the rotors.

摘要： An apparatus for controlling temperature and pressure may include:
a shaft (10) installed in an aircraft, the shaft (10) being rotatable by having a motor (11) coupled thereto;
a compressor (20), rotatable by being connected to the shaft (10), configured to form a flow of heated compressed air by compressing external air introduced into the aircraft;
a heat exchanger (30) configured to heat-exchange the heated compressed air with a portion of external air introduced into the aircraft;
a turbine (40), rotatable by being connected to the shaft (10), configured to form a flow of cooling air by expanding the heat-exchanged compressed air;
and a cooling heat exchanger (50) configured to exchange heat between a refrigerant cooling a fuel cell power train (5) in the aircraft and the cooling air.-

摘要： An example system includes a turbine (124) comprising an input port and mechanically coupled to a motor-generator and a compressor (120) and control circuitry (42) configured to determine whether a pressure of a fluid at the input port of the turbine (124) is less than or equal to than a threshold pressure (208). In response to determining that the pressure of the fluid at the input port of the turbine (124) is less than or equal to the threshold pressure (208), the control circuitry (42) is configured to cause the motor-generator to operate in motor mode (210). The motor-generator is configured to be mechanically coupled to the compressor (120), and the motor-generator is configured to provide mechanical energy to drive the compressor (120) when operating in motor mode (210).

摘要： An air cycle machine includes a turbine section, a compressor section, an axial flux magnetic gear system electromechanically coupling the turbine section to the compressor section, and a stabilization system for at least one shaft of the air cycle machine. The axial flux magnetic gear system includes a stator (208), two rotors (204, 206), a winding system (214), and a control module (216). Each rotor interacts with the stator such that the rotor rotates when the axial flux magnetic gear system is exposed to an electrical current. The winding system stabilizes the position of the rotors along their rotational axes. The control module is configured to supply the electrical current to at least one of the winding system, the stator, and the rotors to drive rotation of the rotors. The stabilization system stabilizes the position of the at least one shaft of the air cycle machine along the shaft's rotational axis.

摘要： Aircraft air cycle machines include a housing (302), a shaft (304) arranged within the housing, and a first wheel assembly (606) operably coupled to the shaft and arranged within the housing. The first wheel assembly is configured to rotationally drive the shaft. A second wheel assembly (608) is operably coupled to the shaft and configured to be rotationally driven by the shaft. A magnetic assembly (618) is arranged within the housing and along the shaft. The magnetic assembly includes a stator assembly (622) fixedly connected to the housing and a rotor assembly (620) rotationally coupled to the shaft. The magnetic assembly is arranged along the shaft to provide a gear ratio between the first wheel assembly and the second wheel assembly.

摘要： A ram air fan inlet assembly for cabin air compressor (CAC) motor cooling flow enhancement includes a gas path defined by a ram air duct (14) and a fan section (18), a CAC motor cooling return duct (28) having an outlet (32) provided through a wall of the ram air duct, and a centerbody (34) body disposed in the ram air duct. The fan section is disposed immediately downstream and abutting the ram air duct. The ram air duct and fan section share a common axis. The centerbody is disposed about the common axis and configured to reduce of volume of the gas flow path in the ram air duct. The centerbody and the outlet axially overlap.
