A rotor turning system for turning a rotor is provided. The system may include a rotary driver including a rotating drive shaft. A removable rotor grasping element is configured to frictionally grasp at least a portion of an exterior circumference of a portion of the rotor. A drive linkage couples the rotating drive shaft to the rotor grasping element to impart a torque to the rotor with the rotor grasping element to turn the rotor. A rotor grasping element is also provided for grasping a substantially smooth exterior surface of a rotor to allow for turning of the rotor. A related method is also provided.

An actuation arrangement for effecting actuation of a variable stator vane pivotally mounted on a tubular casing. The actuation arrangement includes: an actuator connector connected to the variable stator vane via an actuating lever; an anchor fixedly mounted relative to the circumference of the tubular casing; an actuator; and a belt extending from the actuator to the fixed pulley. The actuation arrangement further includes a movable pulley movable relative to the tubular casing and connected to the actuator connector. The belt has a loop portion provided between the proximal and distal ends which loops around the movable pulley, the loop portion for transferring forces generated in the belt by the actuator to the movable pulley to effect movement of the movable pulley and actuator connector towards the anchor to effect actuation of the variable stator vane via the actuating lever.

An assembly is provided for an aircraft propulsion system. This assembly includes a housing, a rotor and a system. The rotor is next to the housing. The system includes a mechanical load, a belt drive, a cradle, a slide and an adjustment link. The mechanical load is operatively coupled to the rotor through the belt drive. The mechanical load is fixed to the cradle. The cradle includes a track and extends laterally between a first side and a second side. The cradle is coupled to the housing through the adjustment link at the first side. The cradle is pivotally coupled to the housing at the second side. The slide is connected to the housing. The slide is mated with and configured to move along the track. The adjustment link is configured to change a distance between the housing and the cradle to adjust a tension of the belt drive.

A power transmission for a turbine or a compressor has a housing, a first shaft rotatably mounted so as to be rotatable in one direction in the housing, a barrel rotatably mounted so as to be rotatable in a direction opposite to that of the first shaft within the housing, a first plurality of blades affixed to the first shaft and extending radially outwardly therefrom, and a second plurality of blades affixed to the barrel and extending inwardly therefrom. Each blade of the second plurality of blades is interposed between adjacent blades of the first plurality of blades. A second shaft is mounted exterior of the housing so as to drive the barrel in rotation.

A removable rotor grasping element is configured to frictionally grasp at least a portion of an exterior circumference of a portion of the rotor. A drive linkage couples the rotating drive shaft to the rotor grasping element to impart a torque to the rotor with the rotor grasping element to turn the rotor. A rotor grasping element is also provided for grasping a substantially smooth exterior surface of a rotor to allow for turning of the rotor. A related method is also provided.

A fuel system for a gas turbine engine includes a fuel pump to provide fuel flow during engine operation and a transmission system that includes an output shaft coupled to drive the fuel pump, and an input shaft driven through a mechanical link to a shaft of the gas turbine engine. The output shaft drives the fuel pump at a variable speed that is independent of a rotational speed of the input shaft.

The present invention relates to the field of energy recovery from hot exhaust gases, a type of system that is widely used in industrial generator assemblies to produce steam used in industrial processes or cold to cool perishables or to cool environments. The system according to the present invention applies to the recovery of energy from exhaust gases in small generator assemblies, smaller than 10 MW, and comprises a turbo (1) connected to the exhaust gas outlet (2) in a small power plant generator assembly (3) and in which said turbo (1) is connected to a hydraulic pump (4), which generates pressure and transmits this pressure to a hydraulic pressure accumulator (5) which, in turn, sends hydraulic fluid under pressure for a hydraulic motor (6) of constant speed, which moves a pulley (7), and said pulley (7), in turn, moves another pulley (8), installed directly on the alternator shaft (9) of the generator assembly (3). In addition to pulleys (7,8), the movement can be done through a gear/clutch system or through a torque converter.

A cooling system is disclosed. The cooling system includes a controller, and a cabinet. The cabinet encloses a cooling circuit having an evaporator, a compressor, an expansion device, and an air moving unit, each of which communicates with each other. The air moving unit includes a fan, a motor, and a mechanical kinetic energy recovery system (M-KERS) communicating with the fan and the motor.
