  • Rotorcraft fuel system having enhanced crash resistance
    Patent number: 10196151
    Abstract: A rotorcraft includes a fuselage having a fuel tank receiving assembly with a fuel tank positioned therein. The fuel tank including a plurality of interconnected fuel bags operable to contain liquid fuel. A network of straps is disposed about the fuel tank forming a restraint assembly. The network of straps includes at least one perimeter strap extending at least partially about at least two fuel bags and at least one surrounding strap extending at least partially about the at least two fuel bags. The at least one perimeter strap has at least two intersections with the at least one surrounding strap.

  • Fuel drain valve for a turbine engine
    Patent number: 9086016
    Abstract: A valve assembly for an engine, the valve assembly can include a housing; an in-flow port configured for connection with a drain line; a first out-flow port configured for connection with a fuel line; a second out-flow port configured for connection with a disposal line; and a passageway that is rotatable with a handle, the passageway being operable to redirect a flow of a fluid between the fuel line and the disposal line. The handle is configured to impede an attachment of the fluid source to a water wash connection when the passageway is in a position to direct the flow of the fluid from the drain line to the fuel line.
