Abstract
A fiber optic linked flame sensor for continuous optical monitoring of the combustion process within the combustion chamber of a gas turbine engine. The system includes a high temperature optical probe, a fiber optic cable, and electro-optics module. The high temperature probe is mounted on the engine skin and sighted in a manner so as to view the combustion process taking place at its origin just aft to the fuel nozzle. The appropriately constructed fiber optic cable connects the high temperature probe with the electro-optics module. The radiation transmitted via the fiber optic cable is then received by an ultraviolet photodiode located in the electro-optics module and coupled with appropriate electronics.
