Abstract: Disclosed is a lift generating appartus for an aircraft which includes a generally circular principal wing with its peripheral portion bent downward, forming a bowl-shaped space opening downward; a high-pressure gas producing device provided on the principal wing; a plurality of jet nozzles provided within the central portion of the bowl-shaped space in a circular arrangement at angular intervals to jet a high-pressure gas produced by the high-pressure gas producing device radially outward from the central portion of the bowl-shaped space; and suction openings for sucking the external air as a secondary fluid from outside the bowl-shaped space by suction generated by the ejector effect of the high-pressure gas jetted from the jet nozzles. The supply of the secondary fluid into the bowl-shaped space in addition to the high-pressure gas further increases the static pressure within the bowl-shaped space, so that the lift acting on the principal wing is enhanced.
