GAS TURBINE ENGINE OPTICAL SYSTEM

摘要

A turbine engine optical system includes a plurality of viewing ports in an engine case that are circumferentially spaced from one-another. At least one optical device is optically coupled to the ports for viewing an internal chamber defined by the engine case and for depicting at least spatial temperature distributions. The chamber may be an exhaust chamber and the controller may have the capability to correlate events in the exhaust chamber to events in an upstream combustor chamber and may thereby adjust operating parameters of a fuel system of the combustor.

1. A turbine engine optical system comprising:
a plurality of viewing ports in and circumferentially spaced about an engine case located downstream of a combustor section for depicting the spatial temperature distribution in an annular exhaust chamber defined between the engine case and an exhaust cone; and at least one optical device constructed and arranged to receive depictions through the plurality of viewing ports to detect at least exhaust temperature distributions.
