Aircraft generating a lift from an interior thereof

A flying saucer generating a lift from its interior, comprising:

• an equipment main body has a shape of flying saucer, having a plurality of ports over a casing of the equipment main body, and having at least one exit at a lower surface of the casing, a tail or a surrounding area thereof, and having a fluid channel between the ports and the exits;
• and
• an engine, located inside the fluid channel and having an air-in vent and an air-out vent, wherein the air-in vent communicates with the port, and the air-out vent communicates with the exit,
• characterized in that the engine drives the fluid to flow within the fluid channel, the fluid channel is a water channel or an air channel, so that the fluid speed inside the fluid channel and the upper surface of the casing communicating with the fluid channel is larger than that on the lower surface of the casing, resulting in a pressure difference between the upper and lower surfaces of the casing and thus creating a lift, and the fluid channel is an air channel when communicating with the air, while the fluid channel between the ports and the exits is a water channel when communicating with a suction engine in the water;
• having plurality of engines over the flying saucer, wherein the suction engine communicates with the fluid channel.
