The invention provides an in-flight emergency evacuation system in an aircraft which has a seating area comprising of plurality of rows of passenger seats which are positioned on plurality of rails. The passenger seats are slidably movable on the rails. The system further discloses at least one emergency room which is configured to accommodate the passenger seats inside it during an emergency condition for safely ejecting the passengers outside of the emergency rooms. During an emergency condition, the crew members of the aircraft can hit the evacuation button which automatically starts the evacuation process. Once the evacuation button is pressed, the slidably movable motorized passenger seats which are positioned on the rails starts moving in a sequential manner into the emergency room which is capable of accommodating one row of passenger seats at a time and ejecting it outside the aircraft.

An aircraft evacuation assembly for electricity dispersion may include a composite packboard housing defining a packboard compartment, wherein the composite packboard housing is electrically nonconductive, and a girt mounted to the composite packboard housing and disposed in the packboard compartment. The evacuation assembly may further include a metal stud extending through the composite packboard housing, wherein the metal stud includes a first end portion disposed external to the packboard compartment and a second end portion disposed internal to the packboard compartment in electrical contact with the girt. The evacuation assembly may further include a flexible strip attached to an external surface, relative to the packboard compartment, of the composite packboard housing. The flexible strip may be electrically conductive and the flexible strip may extend between and electrically connect the first end portion of the metal stud and an electrical interface.

A lightning strike dispersion structure may include a composite component having an outboard surface, wherein the composite component is electrically nonconductive. The lightning strike dispersion structure may include a metal sheet coupled to and extending across a minority portion of the outboard surface of the composite component, wherein the metal sheet is electrically conductive. The lightning strike dispersion structure may also include a metal stud coupled to and in electrical contact with the metal sheet, the metal stud extending completely through the composite component, wherein the metal stud is electrically conductive.

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.
