Description

a disc propeller

technical field

The invention relates to the field of power thrusters, in particular to a thrust force formed by using an environmental pressure field, so that a mechanism can overcome gravity and other resistances to achieve movement.

Background technique

At present, the technologies that overcome gravity or other assistance to obtain thrust in the medium atmospheric environment include: the use of atmospheric buoyancy (airship), rockets, vane machines, and so on. Commonly used vane machines such as propellers provide the lift required for rising by doing work on the air medium. The turbofan jet engine also obtains thrust through the high-speed rotation of the blades to perform work on the gas at a high speed; because the blades do work on the air, a large amount of vibration and noise will be generated, which will have a serious impact on the occupants and the surrounding environment.

Recently, there have been some applications for the invention of the vacuum lift plate, but the engineering feasibility of the vacuum plate is difficult to realize and lacks practicability.

SUMMARY OF THE INVENTION

The invention is based on the Bernoulli principle of using fluid, when the upper surface of the disc rotates, the lower surface is stationary; because the upper and lower flow rates of the air are different, a surface pressure difference is generated on the upper and lower disc surfaces, which forms a thrust that pushes the disc to move, Especially when the pressure difference reaches or exceeds its own weight, it overcomes gravity to form a lifting force.

Further, the disk thruster is composed of a rotating disk and a fixed disk; the two are coaxial, the power machine is arranged on the fixed disk, the output end is connected with the rotating disk, and a rotary sealing structure is formed between the two disks to ensure that the rotating disk rotates. The pressure field between them is isolated from the outside.

Further, a labyrinth structure with lubricated low-friction pairs is adopted at the sealing positions of the two discs, such as the disc edge and the shaft end, to ensure a reliable sealing effect under the high-speed rotation of the rotary disc.

Further, the power machine may be a power mechanism such as an electric motor, an internal combustion engine, and a transmission mechanism.

Further, the power machine arrangement may be that a single power machine is coaxial with the rotating disk, or a plurality of power machines are evenly distributed on the edge of the disk to drive the rotating disk synchronously.

Further, the balancing machine is installed on the fixed disk to balance the moment of inertia of the rotating disk. By changing the rotational speed, the change of the rotation angle of the fixed disk is realized.

Further, the balancing machine can be driven by the power machine in a unified manner, and after passing through the speed change system, the inertia disc is driven in the reverse direction.

Further, the balancing machine can be driven by other power systems to drive the inertia disk, and its rotation direction is opposite to that of the power machine.

Further, the power source and the control system are arranged on the fixed plate to realize the energy supply and speed control of the power machine and the balancing machine.

Further, the power source and the control system can also be arranged outside the mechanism, and the weight of the disc propeller can be reduced by means of wire connection. The control system can also be controlled by wireless control.

Further, the disk thruster arranges a solar film above the rotating disk to make full use of external energy and reduce its own energy consumption.

Further, a piloted flight cabin or a cargo compartment can be hung under the fixed disk of the disc thruster to realize manned or unmanned driving.

Further, as a power propulsion unit, a plurality of disk thrusters can be used in parallel or in series.

The invention utilizes the pressure difference of atmospheric pressure on the outer surface of the disc thruster to obtain thrust, and has low energy consumption, high efficiency, low noise and vibration, large lift per unit size, simple structure and high reliability. The principle of the invention can be applied to various fluid occasions, and can replace the propeller and other power blades as the power drive unit in the vehicle, and the market prospect is considerable;

The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, characteristics and effects of the present invention.

The technical solution of the present invention is described in detail below.

As shown in Figure 1, the structure of the disk thruster consists of two upper and lower disks: the rotating disk (1) is on the top, and the fixed disk (3) is on the bottom; a power machine (2) is arranged on the fixed disk (3), and the power machine is output. The shaft (2) drives the rotating disk; the cavity between the rotating disk (1) and the fixed disk (3) is sealed, and there are rotary sealing structures (5) on the edges of the two disks.

As shown in Figure 1, in order to balance the moment of inertia of the rotating disk (1), a balancing machine (5) is arranged on the fixed disk (3); the power source (4) on the fixed disk (3) is used to provide the power machine ( 2) and the energy of the balancing machine (5); the control system (7) controls the rotational speed of the power machine (2) and the balancing machine (5).

As shown in Figure 2, the power machine (2) drives the rotating disk (1) to rotate, the air flow generated on the upper surface of the rotating disk (1) causes the surface pressure to decrease along the radial gradient, and the air on the lower surface of the fixed disk (3) is still, The surface pressure is greater than the upper surface pressure of the rotating disc (1), thereby forming a thrust to push the fixed disc. When the upper and lower pressure difference is greater than its own gravity, the disc thruster is lifted off the ground.

The rotary sealing structure (6) between the rotating disc (1) and the fixed disc (3) is a labyrinth structure on the two sealing rings (surfaces), the surface is made of low sliding friction material, and the sealing method is added with lubricating medium. In order to ensure that its structure can work for a long time, the lubrication system will provide the required pressure and circulating supply of lubricating oil (grease).

In order to reduce the weight of the disc propeller, the structures of the rotating disc (1) and the fixed disc (3) are made of high-strength, high-rigidity materials and lightweight keel structure, and the outer skin material is made of compressive lightweight materials, such as aviation High-strength engineering plastics such as aluminum plate and carbon fiber;

The power machine (2) can use an electric motor or an internal combustion engine with light weight and high power ratio; the power source (4) can use a lithium battery or a fuel cell with high specific energy.

In order to reduce the weight of the mechanism, a power source (4) and a control system (7) can be arranged outside the mechanism, and are connected with the power machine (2) and the balancing machine (5) by a wire harness. The control system (7) can also be connected by wireless communication.

Regarding the arrangement of the power machine (2), in addition to the central power machine, several power machines (2) can also be arranged on the edge of the rotating disk (1) to drive the rotating disk (1) with a combined force. Alternatively, according to the motor principle, NS permanent magnet materials arranged alternately on the edge of the rotating disk, armatures are arranged on the edge of the fixed disk (3), and the rotating disk (1) is driven by electromagnetic force to rotate around the disk axis.

The balancing machine (5) is fixed on the fixed plate (3), and the function is to balance the inertia of the rotating system such as the rotating plate (3). The balancing machine (5) can be driven by an independent power mechanism, and its rotation direction is opposite to that of the power machine (2);

A solar energy receiving panel can be arranged on the outer surface of the rotating disc (1) of the disc thruster, so as to make full use of green energy, reduce its own energy consumption and increase the flight duration.

The cockpit or cargo hold is hung on the lower part of the fixed disk of the disc thruster to become a manned or unmanned aerial vehicle, which realizes take-off and landing without runway, and is suitable for transportation in urban and runway-less occasions.

As a propulsion unit, the disc thruster can be used in parallel or in series in multiple groups to provide thrust to the aircraft.
