First Claim
Patent Images
1. A gas turbine engine, comprising:
- a compressor;
a combustor in fluid communication with the compressor;
a turbine in fluid communication with the combustor; and
an active balancing system configured to balance at least a portion of the gas turbine engine during operation of the gas turbine engine, including;
a static engine component having a first magnetic element;
a rotor component operative to rotate about an axis, the rotor component having a second magnetic element, wherein the second magnetic element and the first magnetic element are disposed to be positioned opposite each other at one point during a rotation of the rotor component;
a vibration sensor configured to sense a vibration in the gas turbine engine; and
a controller configured to execute program instructions to activate one or both of the first magnetic element and the second magnetic element to selectively attract one to the other or to selectively repel one from the other based on an output of the vibration sensor to reduce the vibration.
