Abstract
A turbine engine (10) having an optical pyrometer (38) for temperature measurement within the turbine (24) is disclosed. The shroud (64) of the turbine has a deflection surface (142) on the downstream side of an aperture (60) through which the pyrometer (38) images an area (56) in the turbine. The deflection surface (142) deflects into the flow path (26) of the combustion gas particulates which would otherwise enter a plenum (134). The imaging probe (52) of the pyrometer (38) is surrounded by a plenum (134) along its axial length to provide an air purging arrangement for the plenum (134) and the lens (66). Various geometrical relationships between the probe (52) and the shroud (64), and between the probe and the inner surface (98,136) of the plenum (134) are employed to minimize entry of particulates into the plenum and to provide an aerodynamically efficient purging system. Air tapped from a compressor (12) is used to cool the pyrometer (38) and supply the plenum (134).
