220 Bernd Kroplin The Flying Roof The mixture of the buoyancy principle and the Japanese Kite tradition lead to the design of a station roof.The stadium can be closed or opened within half an hour.The roof is parked in the air outside of the station and is stabilized like a kite,see Fig.12. The Paraglider Finally the good old parachute combines the externally prestessed membrane and the inflated membrane and receives from an intelligent combination of both its stability and its flight control see Fig.13.
