Patent ID: 8448892

Claim:
An aircraft generating a lift from its interior, comprising: an equipment main body has a shape of triangle and can move in the air, in the water and on the ground; the equipment .main body which can move in the air and water has a fluid channel communicating with a suction engine, wherein the air-in vent and the air-out vent of the engine can be closed in the water, the fluid channel is an air channel when communicating with the air, and is a water channel when communicating with the suction engine in the water, and wherein the fluid channel is used for water storage; 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, 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.
