    Abstract: A purging air flow system for passing air over a lens to keep it clean and free from particulate contaminants and also for providing a positive flow of air away from the lens has baffles which cause a flow across the lens that is not symmetrical to avoid a dead air or stagnation zone in the center of the lens. The air supply used for such purging is controlled adequately so the flow changes direction and particles are removed from the main flow of purge air by inertial separation prior to the time the air contacts the lens. Such air entrained particles might otherwise deposit on the lens. A flow control orifice also may provide a secondary flow to carry the particles separated from the main flow out of the flow passageway.

    Abstract: Disclosed is a fuel injector for a gas turbine engine combustor that includes a fuel nozzle for injecting fuel into the gas turbine engine combustor and a fiber optic microphone operatively associated with the fuel nozzle for measuring acoustic pressure differentials within a combustion chamber of the gas turbine engine combustor. The fiber optic microphone includes a fiber bundle having at least one light transmitting fiber and one light receiving fiber; and a dynamic pressure-sensing diaphragm operatively spaced apart from a sensing end of the fiber bundle. The diaphragm has a reflective surface and is formed from a material capable of withstanding temperatures associated with flame exposure. The diaphragm is adapted and configured for deflecting in response to acoustic pressure changes within the combustion chamber. The fuel injector can further include a mechanism for measuring the temperature of the diaphragm, so as to account for changes in the material properties of the diaphragm caused by temperature changes in the combustion chamber.
