Abstract: An inflatable evacuation slide is presented that includes an aerodynamic spoiler to kill the lift caused by air flowing laterally over the slide. The slide preferably comprises a fabric sliding surface stretched between two longitudinal main side members. The spoiler comprises a fabric panel, supported by a plurality of fabric gussets, that extends outward from each of the main side members. When the main side member of the slide is exposed to a lateral wind load, the spoiler creates a flow separation that kills the lift generated by the airflow. By killing the lift induced by the airflow over the top of the inflatable evacuation slide, zero or negative lift is generated by the airflow over the inflatable evacuation slide, which causes the slide to deploy downward firmly contacting the ground even in high wind conditions.

Abstract: An inflatable emergency evacuation slide system comprises a slide pack (60) with an emergency evacuation slide (10) stored in an uninflated, folded condition together with an inflator (30). A manual inflation lanyard (38) having a mechanical stop (44), such as a crimped ferrule located along its length, is routed in a conventional manner to a point proximal the girt bar (64) securing the evacuation slide (10) to the aircraft (20). The manual inflation lanyard (38) is routed through a grommet (46) at one end of an automatic inflation lanyard (50), the other end of which is attached to the aircraft exit door (18). In operation, when the aircraft exit door (18) is opened in the armed condition, the evacuation slide pack (60) is released from its storage compartment and is dropped from the emergency evacuation exit.
