Abstract: The present invention relates to a lift generation apparatus for vertically taking off/landing a drone or an airplane, and more specifically, to a vertical takeoff/landing apparatus capable of making it possible to generate the maximum lift by spraying a fluid in the opposite direction to the rotary direction of an airfoil to increase its relative speed. Meanwhile, the most frequently used method currently is to place a large number of propellers in the case of a drone, to use a pressure spray method of Harrier jets, and to make an airplane take off or land on a long runway by using a centrifugal compressor apparatus. However, the conventional internal combustion engine, aviation engine, etc., use fossil fuel for driving, thereby contaminating the environment, making severe noise from the propellers, spraying wind toward the ground surface, and scattering dust, which are some of their many problems. The present invention is devised to effectively solve such problems, and aims to supply a fluid to flow in the opposite direction to the rotary direction of the airfoil generating lift, to increase the relative speed of the lift wings, to have a high climbing power, to not pollute the environment, and to provide the optimal vertical takeoff/landing apparatus for drones and airplanes. Accordingly, the present invention is an essential one.
