APPARATUS, SYSTEM AND METHOD FOR OBSERVING COMBUSTOR FLAME IN GAS TURBINE ENGINE

摘要

PROBLEM TO BE SOLVED: To accurately observe and track combustor flames moving in a combustion chamber of a gas turbine engine.SOLUTION: A fuel injector for a gas turbine engine includes: a nozzle body for injecting fuel and air into a combustor; and an on-axis optical probe located within the nozzle body for observing combustor flame radiation, wherein the optical probe includes a plurality of optical fiber bundles extending to a distal end of the probe, and a shaped lens is supported at the distal end of the probe to provide a multi-directional field of view of combustion characteristics and properties in an operating gas turbine engine combustor.
