Patent number: 10450866Abstract: A rotor of an aircraft engine includes a disk wheel and at least two turbine blades. A damping device is arranged below a blade platform and inside a cavity between the blades in the radial direction. The cavity is formed by a respective recess at adjoining blades, with respective recesses having an outer guide surface in the radial direction, acting together with the damping device during operation of the rotor. The guide surface extends radially, from the lateral edge area of the blade to the central area of the blade. The respective recess extends circumferentially from a boundary plane defined by the lateral edge area of the blade to a side surface that delimitates the guide surface towards the blade center. The recess of at least one of the adjacent blades completely receives the damping device.Type: GrantFiled: July 22, 2016Date of Patent: October 22, 2019Assignee: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventors: Markus Weinert, Tobias Leymann
