Abstract: A shaft power transfer system includes a first mechanical clutch mechanism operably coupling a high-pressure shaft to a low-pressure shaft. The first mechanical clutch mechanism transfers power from the high-pressure shaft to the low-pressure shaft at a predefined first speed transient condition. The system further includes a second mechanical clutch mechanism that operably couples the low-pressure shaft to the high-pressure shaft. The second mechanical clutch mechanism transfers power from the low-pressure shaft to the high-pressure shaft at a predefined second speed transient condition where the predefined first speed transient condition is different than the predefined second speed transient condition.

Abstract: A clutch assembly includes a clutch pack, and a rotating control piston selectably engageable with the clutch pack via movement of the clutch piston along an axis of rotation of the control piston. The clutch piston includes a piston member engageable with the clutch pack, a cover plate installed into the piston member to define an enclosed volume, and an axially fixed chamber divider positioned in the enclosed volume to divide the enclosed volume into a control pressure chamber and a pressure balancing chamber. Both the control pressure chamber and the pressure balancing chamber are filled with hydraulic fluid, and the control piston is moved between a disengaged position and an engaged position via modulation of hydraulic pressure in the control pressure chamber.

Abstract: A propulsion system includes a propulsor having a driveshaft, an electric machine coupled to the driveshaft of the propulsor, and a combustion engine having an output shaft. The propulsion system additionally includes a one-way clutch operable with at least one of the driveshaft of the propulsor and the output shaft of the combustion engine. The one-way clutch allows for a differential angular velocity of the driveshaft relative to the output shaft in a first circumferential direction and prevents a differential angular velocity of the driveshaft relative to the output shaft in a second circumferential direction.

Abstract: Disclosed is a high-speed section disconnect for a driven turbocharger with a traction drive. The turbo shaft is attached to a turbine and compressor, and interfaces with a high-speed traction drive. A mechanical coupling connects the traction drive to a transmission, which is connected to the engine so that power can flow to or from the turbo shaft, but the mechanical coupling can be selectively disconnected so that the high-speed section of the driven turbocharger can also be decoupled from the engine during certain operating conditions to reduce mechanical losses in the system.

Abstract: An aircraft propulsion system includes a fan, a primary powerplant, an augmenting powerplant and a controller. The primary powerplant is coupled to the fan and configured to rotate the fan during a first flight stage and during a second flight stage. The augmenting powerplant is coupleable with the fan. The controller is configured to cause the augmenting powerplant to drive the fan during the first flight stage, and to cause the augmenting powerplant to cease driving the fan based on an indication of a transition from the first flight stage to the second flight stage.

Abstract: A gas turbine engine includes a fan and a first drive shaft connected to the fan. A fan drive gear box connects the first drive shaft to a second drive shaft and is configured to allow the first drive shaft to rotate at a different speed than the second drive shaft. The gas turbine engine also includes a sprag clutch disposed circumferentially around the first shaft and connected to the first drive shaft. The sprag clutch is configured to allow rotation of the first drive shaft and the fan in a first direction while prohibiting rotation of the fan and the first drive shaft in a second direction.

Abstract: A gas turbine engine clutch includes a dry clutch assembly, forward and aft working areas, and a shaft. The dry clutch assembly is operative to receive power from a gas turbine engine. The dry clutch assembly is configured to selectively engage the gas turbine engine with a driven source, and has an axial opening extending therethrough. The forward and aft working areas are disposed at axially opposite ends of the dry clutch assembly. The shaft extends axially through the axial opening of the dry clutch assembly, and defines an axial fluid flow passage therethrough in liquid fluid communication with the forward and aft working areas.

Abstract: A method and system improving energy efficiency of a turbojet engine by optimizing rotating speed of a fan and operability of an engine, by freeing the fan from exclusive control of a low-pressure (LP) shaft by providing combined control with a high-pressure (HP) shaft when cruising power has been reached. The turbojet engine include at least one LP turbine and one HP turbine coupled to coaxial LP shafts and HP shafts, respectively, which can drive LP and HP compressors, respectively. The LP compressors include a fan that forms a first primary air-intake compression stage. The LP and HP shafts are mounted on one of two driving mechanisms, an inner ring gear, and a planet carrier for a planetary gear train for driving the fan, the HP shaft being mounted on a disengagement mechanism and the fan being coupled to the planetary gear train via an outer driven ring gear.
