Airfoil for steadying an evacuation slide
First Claim
Patent Images
1. An inflatable slide for use in an emergency evacuation system of an aircraft, comprising:
- a main body having a top surface, a bottom surface, a first side, a second side, and a width extending from the first side to the second side, the main body being configured to inflate in response to receiving a flow of fluid;
a first lanyard coupled to the main body;
a second lanyard located nearer the second side than the first lanyard;
a first slip ring slidably coupled to the first lanyard and a second slip ring slidably coupled to the second lanyard; and
an airfoil coupled to the first slip ring and the second slip ring to facilitate movement of the airfoil towards at least one of the first side or the second side, the airfoil being configured to exert a force on the main body in a downward direction corresponding to a direction of gravity in response to receiving a wind flow, wherein the first slip ring and the second slip ring facilitate movement of the airfoil towards the first side and the second side of the main body via the first lanyard and the second lanyard.
