Abstract: An automated method for restoring an end surface of a cylindrical component of a turbine engine by cutting a profile into the end surface is provided. A base of a cutting device is installed against an inner diameter of the cylindrical component. The base is the aligned to the end surface. A cutting head of the cutting device is positioned to a desired position to enable the cutting. A motor of the cutting device is activated to rotate the cutting head about a central axis of the cylindrical component to cut the end surface of the cylindrical component. A profile of the end surface is created by the cutting of the end surface via the motor. Upon activation of the motor, the cutting device is guided along a circumferential direction against the end surface. A system for cutting a profile into a surface of a cylindrical component is also provided.

Abstract: System and methods for predicting a turbomachine engine safe start clearance following a shutdown of the turbomachine engine is provided. The system includes a controller operatively connected to a plurality of temperature detecting means (TDM). The TDMs are arranged at an upper and lower part of the engine casing, and are configured to sense parameters of the engine and to transmit the sensed parameters to the controller. The controller is configured to receive the sensed parameters and to determine, via a control application of the controller, whether components of the engine have sufficient clearance. The controller is further configured to transmit the clearance information, e.g., to a user. Based on the clearance information, the turbomachine engine is restarted.
