A foldable kite has a flexible central panel having at least four edges. An even total number of flexible tubes are attached to the central panel, at least one tube being arranged on each of two opposing sides thereof. The flexible tubes are conical in shape so that air entering at the top end of the tube is compressed in a ram-jet action to exit out of a reduced opening at the other end of the tube. The ram-jet action is enhanced by a diaphragm which is centrally arranged within each tube. A rigid support for the central panel is arranged to extend parallel to the side edges thereof. A drogue stabilizes the kite during flight, and additionally functions as a carrying case for the kite.
