Patent ID: 7231817

Claim:
An inspection system for a turbine engine, comprising: at least one receiver coupled to a component of a turbine engine proximate to a turbine blade assembly; at least one cylindrical support housing coupled to an outer surface of an outer turbine cylinder; at least one generally elongated outer housing extending at least from the at least one cylindrical support housing coupled to an outer surface of an outer turbine cylinder through the at least one receiver coupled to a component of a turbine engine and biased towards the at least one receiver and towards the turbine blade assembly; wherein the outer housing is supported with a substantially spherical bearing that is coupled to an outer surface of the outer housing and bears against an inner surface of the at least one cylindrical support housing to form a seal sealing the outer housing to the at least one cylindrical support housing; wherein the inner surface the at least one cylindrical support housing is generally parallel to a longitudinal axis of the outer housing enabling axial movement of the outer housing relative to the at least one cylindrical support housing while maintaining a seal between the outer housing and the at least one cylindrical support housing regardless of axial movement of the outer housing relative to the at least one cylindrical support housing.
