ABSTRACT:
Support apparatus for stabilizing an inflatable aircraft escape slide both during deployment and use is disclosed. The support apparatus includes a series of panels or links that are hinged together to form a mechanical girt (support). The upper end of the mechanical girt is attached to a girt bar that is mounted near the lower region of the aircraft egress door to secure the upper end of the escape slide. The mechanical girt is deployed through the aircraft door with the escape slide. As the mechanical girt swings against the exterior surface of the aircraft, latching mechanisms automatically engage mating catches located on the aircraft exterior near the sill of the aircraft door and at a location near the lower edge of the mechanical girt to securely fasten the mechanical girt to the exterior surface of the aircraft. A lower girt bar, that extends across a lower region of the mechanical girt is connected to the inflatable escape slide by a lower girt. The lower girt is dimensioned and arranged to be under tension prior to the full inflation of the escape slide to thereby stabilize the escape slide as it is inflated and utilized for descent. In addition to (or in place of) the lower girt, stabilizing straps are connected from the lower edges of the mechanical girt to positions on the escape slide that are located outwardly of the upper slide terminus. These straps are also dimensioned and arranged to be under tension prior to the full inflation of the escape slide to thereby stabilize the slide.
