A multistage aspirator for an inflatable assembly may comprise a first end defining a primary gas inlet and a second end defining a gas outlet. An internal surface of the multistage aspirator may define a flow path extending from the primary gas inlet to the gas outlet. A first stage of the multistage aspirator may include a first stage orifice extending from the internal surface to an external surface of the multistage aspirator. A second stage of the multistage aspirator may include a second stage orifice located downstream of the first stage orifice and extending from the external surface to the internal surface.

Described is a system for the emergency evacuation of persons from a structure, such as a building, ship, raised platform, stadium or the like, comprising supporting means, designed to be positioned at a window of said structure for the emergency evacuation from said structure; at least one load-bearing structure, coupled with said supporting means, comprising in turn a plurality of modules, each comprising two inflatable longitudinal tubular elements positioned parallel to each other, said modules being positioned in series with each other; a slide having a surface on which the persons evacuated from said structure can slide, said slide being interposed between said two inflatable longitudinal tubular elements of said modules; and a pneumatic inflation system for the selective inflation of said two inflatable longitudinal tubular elements of said modules.

Methods are disclosed for replacing expired or unserviceable aircraft emergency slides (“slides”) in an aircraft. The disclosed methods utilize containers that are configured to securely retain both unserviceable slides and serviceable slides at different times in different configurations as installation tools. The container can be placed on an aircraft through the main door of the aircraft, and are further configured to be easily transported within the aircraft from a staging area of the aircraft to a slide installation and removal point at either the main door or an emergency exit door of the aircraft. The containers can be aligned with the installation and removal point to facilitate replacing an unserviceable slide with a new, serviceable slide. The disclosed methods and containers improve personnel safety concerning lifting and handling of the slides, which are heavy. The containers and methods disclosed herein further facilitate positioning of the slides near installation and removal points and properly orienting the slides, while reducing awkward handling situations for personnel.

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.

An aircraft cabin section with an aircraft door, a cabin floor, and at least one lining mounted to the aircraft door. The aircraft cabin section further comprises at least one seal that is mounted to the at least one lining and seals a space between the at least one lining and the cabin floor. This prevents a cold air draft from entering the aircraft cabin.
