    摘要： An aspirator assembly for inflating an emergency slide. The aspirator assembly includes a bell housing, a mixing chamber, and a nozzle assembly. The bell housing includes a ring defining an inlet port at which a check valve is located and into which ambient air can flow. The mixing chamber has an outlet port, The nozzle assembly is located in the mixing chamber and includes plural passageway sections defining concentric rings and cross bars. The passageway sections include internal passageways in communication with plural nozzle jets through which a compressed air is introduced into the mixing chamber to mix with the ambient air. The passageway sections are of an airfoil shape cross-section having a rounded leading end directed towards the inlet port and a trailing end is directed toward the outlet port to reduce air turbulence within the mixing chamber.

    摘要： A valve arrangement for inflating an inflatable device includes a valve body comprising an inlet, an outlet, a main fluid channel, a first ball detent, and a second ball detent. A lifter and a sleeve are located in the main fluid channel. A locking ball is disposed at least partially within a locking ball aperture disposed in the sleeve. A piston is coupled to the lifter and fluidly coupled to a command pressure cavity of the valve body. A spring biases the lifter toward a ball locking position whereby the lifter urges the locking ball at least partially into the first ball detent. A valve operation initiator controls a flow of pressurized gas into the command pressure cavity to urge the lifter to a ball releasing position to free the sleeve, as to the locking ball, to translate to an open position to fluidly couple the inlet with the outlet.

    摘要： An evacuation guidance system may comprise a plurality of floor guidance lights, a plurality of seat guidance lights, a plurality of exit signs, and a controller in communication with the plurality of floor guidance lights, the plurality of seat guidance lights, and the plurality of exit signs. The plurality of floor guidance lights may include a plurality of fore-aft floor lights and a plurality of port-starboard floor lights. The controller may be configured to determine a closest exit door to each floor guidance light, each seat guidance light, and each exit sign. The controller may command each floor guidance light, each seat guidance light, and each exit sign to indicate a direction of the closest exit door.
