Estimating the term…
A turbomachine, a computing system for a turbomachine, and a method for overspeed protection are provided. The turbomachine includes a first rotor assembly interdigitated with a second rotor assembly together operably coupled to a gear assembly. A plurality of sensors is configured to receive rotor state data indicative of one or more of a speed, geometric dimension, or capacitance, or change thereof, or rate of change thereof, relative to the first rotor assembly or the second rotor assembly. A controller executes operations including receiving rotor state data from the plurality of sensors; comparing rotor state data to one or more rotor state limits; and contacting one or more of the first rotor assembly or the second rotor assembly to a contact surface adjacent to the respective first rotor assembly or the second rotor assembly if the rotor state data exceeds the rotor state limit.
A computing system for a turbomachine, wherein a first rotor assembly is interdigitated with a second rotor assembly, and wherein the first rotor assembly and the second rotor assembly are operably coupled to a gear assembly, and wherein a fan assembly is operably coupled to receive power from the gear assembly, wherein the computing system is configured to execute operations, the operations comprising:
