Lift generating apparatus, an aircraft employing the lift generating apparatus, and a lift generating method.

摘要

A lift generating apparatus for an aircraft comprises a generally circular principal wing (1) with its peripheral portion bent downward, forming a bowl-shaped space (4) opening downward; a high-pressure gas producing device (10) provided on the principal wing; jet nozzles (13) provided within the central portion of the bowl-shaped space (4) in a circular arrangement at angular intervals to jet a high-pressure gas produced by the high-pressure gas producing device (10) radially outward from the central portion of the bowl-shaped space (4); and suction openings (16) 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 (13). 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 (1) is enhanced. The high-pressure gas jetting rate of each jet nozzle is regulated to produce a horizontal thrust for horizontal flight.
