Rescue aid for shipwreck - has reflecting kite with inflated sections

摘要

The shipwreck rescue aid has a self inflating shape tied to the survivor as a kite and coated with reflecting material for optical- and radar identification. The shape is delta to provide aerodynamic lift even in high winds. The delta shape has several sections each independently inflated with a lighter than air gas. The securing ties hold the shape in correct attitude for flight and provide better lift than a mere balloon shape.
