  • Tangential air entry fuel nozzle
    Patent number: 5479773
    Abstract: The two scrolls 22 forming air inlet slot 20 are each formed of a fixed vane 36 and a floating vane 38. The thin and hot floating vane 38 is secured to the massive and cooler fixed vane 36 with a longitudinal slidable joint 42. The floating vane may expand without restraint of the fixed vane, so that buckling is avoided and inlet slot 20 is uniform.

  • Gas turbine engine cooling air flow
    Patent number: 5157917
    Abstract: A turbofan engine uses fan air to cool bounding surfaces of the exhaust duct at all times. A portion of the fan air flow is used for augmentor combustion in the augmentation mode. In the non-augmented mode the flow for combustion is stopped and the cooling air is used to cool the tail cone and exit guide vanes. Infrared radiation is thereby reduced when non-augmented.

  • Control connector
    Patent number: 4440423
    Abstract: A two member control connector for joining multiple hydraulic control conduits (20) has one member (14) attached to the underwater equipment. The other member (10) is raisable to the water surface and also carries annular seal assemblies (24) around the mating ends of the conduits (20). The seal assemblies are each retained in a dove-tail groove (26). A vent passageway (42) is also provided in either the seal or the member (10) to prevent the occurance of differential pressure under the assembly, possibly resulting in seal loss.
