Foil Kites
Sportair has focused our attention on Foil Kites, specifically for use on land. Foil Kites are recognisable by their similarity to an air bed, as they have cells that are filled with air, and are often refered to as Lie Lows. This air in cells is what gives the kite its shape, and the more air rammed into the cells by movement, the better the kites holds its shape. This also gives them the name of Ram Air kites.
Essentually, Foil Kites have two skins (Twin Skin), the air is directed between these skins, and into divisions, or cells, through openings in the leading edge of the kite. It is the way that the skins, and cells are positioned that provides the shape of the kite.
