Abstract: An aspirator system for inflating an inflatable evacuation device includes an aspirator body having a plurality of flapper doors configured to open to allow intake of atmospheric gas. The aspirator system also includes an aspirator barrel connecting the aspirator body to the inflatable evacuation device, having connected inflation chambers wrapping around a circumference of the aspirator barrel and arranged along a length of the aspirator barrel, and being configured to provide an aspirator barrel chamber for guiding the atmospheric gas to the inflatable evacuation device when the aspirator barrel is inflated. The aspirator system also includes a showerhead nozzle connected to the connected inflation chambers, configured to direct high-pressure gas to inflate the aspirator barrel and compel intake of atmospheric gas through the plurality of flapper doors, to inflate the inflatable evacuation device.

Abstract: According to various embodiments, disclosed is a beam structure comprising a four-point cross section for an inflatable article comprising an inflatable slide. The beam structure has greater beam strength and provides greater structural support than an inflatable beam having a traditional circular cross section.

Abstract: An inflatable evacuation slide is provided. The slide may comprise a slide surface with a tubular member coupled to the slide surface. The tubular member may comprise a translucent material defining a chamber internal to the tubular member. A light source may be directed into the chamber and configured to illuminate the tubular member from within the chamber.

Abstract: An evacuation system is provided. The system may comprise a door sill, a girt coupled to the door sill, a slide coupled to the girt, and a measurement device coupled the girt and/or the slide. The measurement device may further comprise a line having a predetermined length and a weight coupled to the line, and the measurement device may be configured to adjust a length of the slide in response to a position of the weight. A method is also provided. The method includes opening a door to expose a door sill, inflating the emergency slide with the emergency slide coupled to the door sill, and deploying a measurement device configured to measure a height of the door sill from a surface. The measurement device may comprise a line coupled to the door sill and a buoyant weight coupled to the line, and wherein the line has a predetermined length.

Abstract: Disclosed is an emergency slide system comprising a slide having a telescoping structural support, and a slide surface. The emergency slide system further comprises a gas deployment device comprising a gas generator, compressed gas cylinder, or both. The gas deployment device may further include an aspirator, according to various embodiments. The telescoping structural support provides a more compact and quickly deployable system.
