US 5,349,850 A · Instrumentation light probe holder

Abstract

An instrumentation light probe holder for use in observing and measuring operating characteristics of rotating blades of a gas turbine engine during engine operation or rotating components of a machine during operation is disclosed. The holder includes an elongated cylindrical member for insertion into an opening or bore formed radially through an annular casing of the gas turbine engine or machine housing. The cylindrical member has a hollow interior for receipt of an instrumentation light probe and a first end for insertion into the casing or housing and for holding an operating end of the probe at a selected set-back distance from the rotating blades or components. A grasping mechanism is provided for releasably holding the light probe in the cylindrical member.
