摘要:
An aspirator for inflating an aircraft evacuation slide, emergency raft or other inflatable device includes a flexible, collapsible aspirator barrel that is inflated during operation to form a substantially rigid tube. According to one embodiment, the inflatable support member receives a flow of high pressure air directly from the aspirator injector nozzle assembly. According to another embodiment, the collapsible aspirator barrel receives a flow of high pressure gas directly from the high pressure inflation source. Because the aspirator barrel of the present invention is collapsible, the present invention occupies significantly less space when stored than an equivalent aspirator with a rigid aspirator barrel.
摘要:
An inflatable evacuation slide (12) for emergency evacuation of an aircraft (16) comprises a pair of main support tubes (24,28) supporting a flexible sliding surface (30). The main support tubes (24,28) taper from a widest point near the exit opening of the aircraft (16) to a narrowest point at the foot end (50) of the slide (12). This arrangement of main support tubes (24,28), together with the toe end transverse tube (54) and the head end transverse tube (56), form a quasi-trapezoidal truss structure, which is inherently more stable than the rectangular slides of the prior art.
