Abstract: There is disclosed an auxiliary rotation device 28 for a gas turbine engine 10. The auxiliary rotation device 28 comprises: an electric machine 30 configured to be coupled to a rotor of the gas turbine engine 10; and a dedicated electrical storage device 32 coupled to the electric machine 30. During a period of powered operation of the gas turbine engine 10 the electric machine 30 is configured to act as a generator so as to charge the dedicated electrical storage device 32. Following the period of powered operation of the gas turbine engine 10 the electric machine 30 is configured to act as a motor by discharging the dedicated electrical storage device 32 so as to cause the rotor to rotate for a period of time to provide even cooling of the rotor around its circumference. There is also disclosed a method of cooling a rotor of a gas turbine engine 10 using an auxiliary rotation device 28.

Abstract: A robot for performing diagnostics on a conveyance system is provided. The robot including: a controller configured to control operation of the robot; a propulsion system configured to move the robot to a conveyance system; and a data collection system configured to collect data of the conveyance system, the data collection system comprising at least one of: an inertial measurement unit (IMU) sensor configured to detect an acceleration of a conveyance apparatus of the conveyance system; a camera configured to capture images of the conveyance system; and a microphone configured to detect sound emanating from the conveyance system.

Abstract: A circumferential seal for a rotating component comprising a static seal part and a rotating seal part having a common rotational axis. The rotating seal part comprises a fin seal, wherein the fin seal comprises a protective coating.

Abstract: A variable vane mechanism for adjusting the angle of stator vanes in a gas turbine engine is provided. The mechanism includes a circumferentially extending unison ring that is driven circumferentially around a casing by an actuator. The unison ring is connected to the stator vanes via levers such that the angle of the vanes changes with circumferential movement of the unison ring. The unison ring and the casing are each provided with at least one rigging hole in order to set the initial angle of the vanes. At least one of the unison ring and the casing are each provided with at least two rigging holes, so that the initial angle of the vanes can be adjusted by selecting different combinations of rigging holes. This may allow accumulations in tolerances to be compensated for and/or may allow the engine to be tested at different initial vane angles.
