Flying vehicle

A flying vehicle comprising:

• an annular hollow outer body having an outer circumferential open portion defined in an outer circumference thereof and an inner circumferential open portion defined in an inner circumference thereof, wherein the outer open portion air-communicates with the inner open potion;
• a blade system comprising at least one blade, the blade system being rotatably disposed within the annular hollow outer body, wherein the blade system is configured to allow air flow from the outer circumferential open portion to the inner circumferential open portion;
• a first magnetic system including magnets arranged on the annular hollow outer body and the blade system respectively, wherein the first magnetic system is configured to enable the blade system to be kept to have a clearance with the annular hollow outer body and to be kept in a floated state using a first magnetic force;
• a second magnetic system including electromagnets placed on the annular hollow outer body and permanent magnets placed on the blade system, wherein the second magnetic system is configured to allow the blade system to rotate using a second magnetic force;
• a central inner body surrounded by the inner circumference of the annular hollow outer body;
• a steering system disposed along an outer circumference of the central inner body, wherein the steering system is configured to allow air discharged from the inner circumferential open portion via the blade system to flow upwardly or downwardly;
• a controller disposed within the central inner body, wherein the controller is configured to control rotation of the blade system and operation of the steering system;
• and
• a power supply disposed within the central inner body, wherein the power supply is configured to supply power to the controller and the electromagnets.
