    摘要: An exhaust device for a compressor bypass bleed system of a ducted fan engine includes a housing having an inlet end and an outlet end and defining a centerline axis from the inlet end to the outlet end, an inlet flow conditioner arranged at the inlet end, the inlet flow conditioner including a plurality of inlet openings for conducting a flow of compressed air therethrough into the housing, and an exit screen arranged at the outlet end of the housing. The exit screen includes a plurality of exit openings therethrough arranged at an acute angle with respect to the centerline axis so as to provide a flow of compressed air therethrough into a bypass flow passage at least partially in a same direction as a bypass airflow through the bypass flow passage.

    摘要: A method of operating and cleaning a torch ignitor for continuous ignition includes issuing a fuel-lean flow through a combustion chamber of a torch ignitor. The method also includes heating interior surfaces of the torch ignitor, wherein the fuel-lean flow reacts with carbon deposits on the interior surfaces to remove the carbon deposits.

    摘要: Systems and methods are provided for cleaning one or more cooling passages associated with a combustion chamber of a gas turbine engine. The gas turbine engine has a compressor section upstream from the combustion section. The method includes receiving a pressurized fluid from a source and directing the pressurized fluid through an inlet of a chamber such that a portion of a plurality of particles within the chamber is entrained within the pressurized fluid. The method includes injecting the pressurized fluid with the entrained portion of the plurality of particles downstream from the compressor section through an end wall of a diffuser and deswirl system upstream from a combustor plenum of the combustion section to clean the one or more cooling passages associated with the combustion chamber.
