Description

Disc propeller

Technical Field

The invention relates to the field of power propellers, in particular to a power propeller which utilizes an environmental pressure field to form thrust so that a mechanism can overcome gravity and other resistance to realize movement.

Background

The technology for overcoming gravity or other assistance force to obtain thrust in the current middle atmospheric environment comprises the following steps: using atmospheric buoyancy (airship), rocket, vane machine, etc. Commonly used vane machines, such as propellers, provide the lift required to do work on the air medium to lift. The turbofan jet engine also obtains thrust by high-speed acting on gas through high-speed rotation of the blades; since the blades work on the air, a large amount of vibration and noise are generated along with the work, and the work has serious influence on passengers and the surrounding environment.

Some vacuum lift discs are applied recently, but the engineering feasibility of the vacuum disc is difficult to realize, and the practicability is poor.

Disclosure of Invention

According to the Bernoulli principle of fluid, when the upper surface of the disc rotates, the lower surface is static; because the air has different flow rates up and down, surface pressure difference is generated on the upper disc surface and the lower disc surface, so that the thrust for pushing the disc to move is formed, and particularly, when the pressure difference reaches or exceeds the self weight, the lifting force is formed by overcoming the gravity.

Furthermore, the disc propeller consists of a rotating disc and a fixed disc; the two disks are coaxial, the power machine is arranged on the fixed disk, the output end of the fixed disk is connected with the rotating disk, and a rotary sealing structure is arranged between the two disks, so that the pressure field between the disks is isolated from the outside when the rotating disk rotates.

Furthermore, a labyrinth structure with a lubricated low-friction pair is adopted at the sealing positions of the edge of the two disks, the shaft end and the like, so that a reliable sealing effect is ensured under the condition that the rotating disk rotates at a high speed.

Further, the power machine can be a motor, an internal combustion engine, a transmission mechanism and other power mechanisms.

Furthermore, the power machine can be arranged in a way that a single power machine is coaxial with the rotating disc, or a plurality of power machines are uniformly distributed on the edge of the disc to synchronously drive the rotating disc.

Further, the balancing machine is mounted on the fixed disk to balance the rotational inertia of the rotating disk. The change of the rotation angle of the fixed disc is realized by changing the rotation speed.

Furthermore, the balancing machine can be uniformly driven by the power machine, and the inertia disc is reversely driven after passing through the speed change system.

Further, the balancing machine may be an inertia disc driven by other power systems, the rotation direction of which is opposite to that of the power machine.

Furthermore, the power source and the control system are arranged on the fixed disc, so that energy supply and rotating speed control of the power machine and the balancing machine are realized.

Further, the power source and the control system can be arranged outside the mechanism, and the weight of the disc propeller is reduced through a wire connection mode. The control system can also be controlled in a wireless control mode.

Furthermore, the solar film is arranged above the rotating disc of the disc propeller, so that external energy is fully utilized, and the energy consumption of the disc propeller is reduced.

Further, a flight cabin or a cargo hold can be hung below the fixed disc of the disc propeller, so that manned driving or unmanned driving is realized.

Further, the disc propeller is used as a power propulsion unit, and a plurality of disc propellers can be used in parallel and in series.

The invention obtains thrust by utilizing the pressure difference of atmospheric pressure on the outer surface of the disc propeller, and has the advantages of low energy consumption, high efficiency, low noise and vibration, large lift force under unit size, simple structure and high reliability. The principle of the invention can be applied to various fluid occasions, replaces power blades such as propellers and the like as power driving units in vehicles, and has considerable market prospect;
