  • Gas turbine engine and blocker door assembly
    Patent number: 9803557
    Abstract: A blocker door assembly which may be for a cooling system that may be applied to a gas turbine engine includes a plurality of blocker doors circumferentially spaced about an engine axis. Each blocker door is constructed and arranged to move in a circumferential direction to, at least in-part, control air flow through a passage in an adjacent fixture. A sync-ring is concentrically located about the engine axis, disposed in an annular first duct in direct communication with each passage, and engaged to each one of the plurality of blocker doors for simultaneous operation. The sync-ring is aero-dynamically shaped to reduce surrounding airflow resistance.

  • Bulkhead and fuel nozzle guide assembly for an annular combustion chamber
    Patent number: 5419115
    Abstract: An assembly of a bulkhead 48 and fuel nozzle guide 62 for a fuel nozzle 46 disposed in a combustion chamber 24 is disclosed. Various construction details which provide for positively cooling components of the assembly are developed. In one detailed embodiment, the nozzle fuel guide is spaced from the bulkhead to form an annular gap G.sub.1 which is divided by a heat shield 72 into annular orifices 108, 112 for supplying to cooling air passages 126, 128 bounded by the heat shield 72.
