  • Rotor comprising a rotor component arranged between two rotor disks
    Patent number: 11339662
    Abstract: A rotor of a gas turbine, having two adjacent rotor disks having a plurality of blade-holding grooves for receiving rotor blades, distributed around the periphery thereof, and having an axially extending peripheral ring projection radially beneath the blade-holding grooves. A peripheral rotor component is fixed to the ring projections, between the rotor disks. In order to protect the periphery, the rotor disk or the rotor component includes at least two recesses arranged on the periphery in a distributed manner, in each of which engaging shoulders of the rotor component or the rotor disk engage.
    Type: Grant

  • Apparatus to translate two-dimensional planar positions into three-dimensional fixed radial positions
    Patent number: 10314555
    Abstract: An apparatus includes a base. The base includes a first mount configured to receive a first device. First and second guides overlap each other, are each pivotally coupled with the base, and each include an arcuate body. The chassis is received by the first guide and the second guide so as to be configured for sliding along the first guide and the second guide. The chassis includes a second mount for receiving a second device for movement of the second device between a first set of points defining a reference spherical cap relative to the base. A member may be provided between the chassis and an actuator operable to move among a set of points defining a reference plane so as to cause movement of the chassis among another set of points defining a reference spherical cap about the first mount for the first device.
