A hybrid-electric gas turbine engine and method of operating includes independently controlling a first electric machine providing torque to a first shaft to maintain a desired clearance between a first set of blades rotatably coupled to the first shaft, a...

The invention relates to a method of detecting and localizing partial rotor-stator rubbing during the operation of a turbine, in which the rotor (1) of the turbine is monitored by means of at least one pair of sensors (3, 30, 4, 40) of the rotor vibrations...

The device includes a longitudinally-extending sheet metal piece (46) constituting a heat shield arranged upstream from the upstream radial wall (18) of a spacer sector (16) against the inner surface of a casing (14). The sheet metal piece bears axially ag...
