An embodiment of the disclosed method and apparatus relates to a system for detecting a rub in a turbomachine. The system includes a turbomachine; sensors monitoring turbomachine conditions; and an on site monitor in communication with the sensors, and loaded with instructions to implement a method for detecting a rub in the turbomachine.

Method and apparatus for detecting rub in a turbomachine

A number of sealing segments,mounts a brush seal about a rotor. The tips of the brush seal,are maintained out of contact with the rotor surface throughout the entire operating range of the turbomachinery. Thus, the increase in temperature resultant from rubs between the bristle tips and the rotor,which effectively increase vibrations of the turbomachinery are eliminated. Brush seals are therefore maintained out of contact with the rotor throughout the entire operating range of the turbomachinery and thus do not affect the dynamic behavior of the rotor.
