A boom for an aircraft, and, more particularly, to a tail boom for a helicopter, whereby the tail boom may comprise a watertight compartment and watertight bulkheads. The watertight bulkheads may close at least one end of watertight compartment. Watertight bulkhead may include attachment device, frame, and watertight fabric.

A bulkhead assembly for an aircraft passenger cabin having a floor and a secondary support member includes upper and lower bulkhead panels and a bulkhead coupling member. The upper bulkhead panel defines an elongated tower portion that protrudes through a slot opening in an overhead closeout panel, and directly or indirectly connects to the secondary support member. The lower bulkhead panel connects to the upper bulkhead panel and to the floor via the bulkhead coupling member. A method for installing the bulkhead assembly in the passenger cabin includes connecting the lower bulkhead panel to the floor, joining the lower bulkhead panel to the base of the upper bulkhead panel using a bulkhead coupling member, inserting the terminal end through the slot opening, and connecting the terminal end to the secondary support member behind the overhead closeout panel.

A tie-down for attachment to an aft tail section of an aircraft for inhibiting damage to the aircraft when the aircraft is on the ground is disclosed. The tie-down has a mount member configured to attach to the aft tail section and a projection member supported by the mount member. The projection member extends in a generally downward direction from the mount member so as to provide a contact surface with the ground that is lower than the aft tail section.

Technologies for providing emergency egress routes for a blended wing body aircraft are described herein. In some examples, the emergency egress routes are through a side cabin bulkhead and aft one or more cargo holds. In some examples, the blended wing body aircraft has wings that are high geometry wings. In these examples, the emergency egress routes do not penetrate an aft spar, reducing weight and increasing the integrity of the aircraft.

A method and apparatus for assembling a hanging scaffold system within the aft pressure bulkhead area of an aircraft to provide access to the pressure dome without contacting the pressure dome. The hanging scaffold system comprises a group of horizontal supports to support at least one floorboard. A group of vertical supports is connected to and extends perpendicularly from the group of horizontal supports. A clamping device is attached to each vertical support of the group of vertical supports and further engages an attachment point on an internal structure of an aircraft.
