An inflatable evacuation slide for emergency evacuation of an aircraft comprises a pair of main support tubes supporting a flexible sliding surface. The main support tubes taper from a widest point near the exit opening of the aircraft to a narrowest point at the foot end of the slide. This arrangement of main support tubes, together with the toe end transverse tube and the head end transverse tube, form a quasi-trapezoidal truss structure, which is inherently more stable than the rectangular slides of the prior art.

Evacuation slide having trapezoidal outline

An aircraft life raft assembly for use as a deployable escape slide from an egress opening of an aircraft. The escape slide is a longitudinally extending structure with a center line that extends from the head end of the slide, adjacent the egress opening, to a toe end that is located adjacent the horizontally extending ground plane. Pressurizing means is operative to inflate the escape slide, which escape slide has panels or panel members of flexible material with an upper sliding surface that extends in the longitudinal direction. The escape slide has a portion of its length that is curvilinear in plan view, which curvilinear portion maybe close to the egress opening of the aircraft or anywhere along the length of the escape slide.

Escape slide

A deployment control for an inflatable escape slide for use in a structure such as an aircraft is disclosed wherein the escape slide has an inboard end and an toe end. The inboard end of the slide is suitably attached to an egress on the structure for deployment and extension of the slide by inflation means whereby the slide extends from an elevated egress to a ground support. The slide has inflatable tubes with a slide surface. The inflation means is operative upon actuation to provide pressurized fluids to the tubes which will inflate and distend the tubes into a longitudinally extending escape slide under the control of a restraining control device (or devices). Such device is operative upon pressurization of the tubes to deploy an outboard portion of the slide to which one end of the device is connected to move relative to the inboard end of the slide to which the other end of the device is connected at a controlled rate for a predetermined length of the slide.
