And/or

Isolation of

In order to reduce the damping effect of the fluid pressure between the back flow surface of the front driving part and the back driving part on the power mechanism, the following three methods can be adopted:

1.1, the capability of the synchronous movement of the front drive back flow surface and fluid is greater than that of the front drive head flow surface; the flow speed of the fluid on the back flow surface of the power front driving part is smaller than that of the fluid on the front flow surface of the power front driving part. (the embodiment can be that the material or the structure with different friction coefficients or different roughness is adopted on the back flow surface and the head flow surface of the front part; the higher the synchronous motion capacity is, the smaller the relative flow speed is)

Detailed Description

A fluid dynamic method for an aerodynamic vehicle, comprising the following steps:

the power mechanism is provided with a power front driving part, one surface of each part of the power mechanism, which faces to the advancing direction of the power mechanism, is a head-on surface, and the other surface, which is back to the advancing direction of the power mechanism, is a back-flow surface; the flow surface of the power front driving part meets the requirement that the pressure of fluid borne by the power front driving part plays a role in damping the advancing of the power mechanism; the fluid power method enables the front driving face to move at a high speed, then enables fluid on the flow surface of the power front driving part and the power front driving part to move relatively, reduces pressure of the fluid on the flow surface of the power front driving part, and enables the front driving part to move to achieve a gain effect on the advancing of the power mechanism.

The power mechanism is provided with a power rear-drive part, and the back flow surface of the power rear-drive part meets the requirement that the pressure of fluid borne by the power rear-drive part plays a role in gaining the advancing of the power mechanism; the fluid power method comprises the step of reducing the damping effect of fluid motion between the back flow surface of the front driving part and the back driving part on the advancing of the power mechanism by adopting a fluid damping effect reduction method.

The fluid damping effect reduction method is characterized in that the flow rate of fluid on the back flow surface of the power front driving part is smaller than the flow rate of fluid on the surface of a part, opposite to the power front driving part, of the power mechanism.

The fluid damping effect reduction method is characterized in that the flow speed of fluid on the back flow surface of the power front driving part is smaller than that of fluid on the front flow surface of the power front driving part.

Furthermore, the rear driving part is kept not to move, or the damping effect on the power mechanism generated by the movement of the rear driving part is smaller than the gain effect on the power mechanism caused by the fluid on the front driving part in the movement process of the front driving part; and then the pressure of the fluid on the front driving part flow surface is smaller than the pressure of the fluid on the rear driving part flow surface.

The driving member is formed on a track in one movement period, and at least 30% of the movement of the driving member on the path is not circular movement.

The distance between the front driving part and the power mechanism satisfies the following conditions: and the fluid on the surface of the power mechanism opposite to the back flow surface of the front driving part moves under the action of the front driving part, and the fluid pressure on the surface of the power mechanism opposite to the back flow surface of the front driving part is reduced.

The working principle is as follows:

the fluid speed on the flow-facing surface of the front driving part is gradually increased, the pressure of the fluid on the flow-facing surface is gradually reduced, the fluid on the rear driving surface is hardly influenced, and a normal pressure value is kept, so that an upward fluid pressure difference is formed between the front driving surface and the rear driving surface, and when the pressure difference is larger than the gravity borne by the power mechanism, the lifting force for suspending or moving upwards is provided.

The core of the invention is as follows:

according to the invention, the reduction of the fluid pressure on the upstream side of the front drive part is obtained through the movement of the front drive surface (a necessary technical scheme), meanwhile, the damping effect of the fluid on the upstream side of the front drive part is weakened (an optional technical scheme), when the resultant force borne by the power mechanism in the vertical and upward direction is increased, the capability of suspending or flying upwards (or floating) is finally achieved by overcoming the self gravity, and the front drive parts in different directions can be adjusted to fly or displace in different directions in the same way. The hydrodynamic method and its use are explained in detail below by 6 examples of "an aerodynamic vehicle".

A fluid dynamic mechanism:

example 1:

an aerodynamic aircraft as shown in fig. 1-5 is provided with one or more groups of aerodynamic mechanisms, each group of aerodynamic mechanisms being provided with one or more aerodynamic mechanisms; the aerodynamic mechanism comprises a power front drive part 1 and an aerodynamic mechanism 3; the power mechanism 3 comprises a main body 30, a motor 31, a storage battery 32 and a control box 33; the main body 30 comprises a cylinder shell 301 and a partition plate 302, wherein the partition plate 302 is fixedly arranged in the cylinder shell 301 and is close to one end of the cylinder shell 301; the motor 31 is fixedly arranged on the isolation plate 302, and an output shaft 310 of the motor 31 penetrates through the isolation plate 302; the front driving part 1 is sleeved on an output shaft 310 of the motor 31 and is arranged on two sides of the isolation plate 302 together with the motor 31; the front drive part 1 is sleeved on the inner side of the cylinder shell 301 through a bearing 2.

The front drive part 1 has a smooth surface on the flow surface, so that the viscosity of the air on the flow surface is infinitely close to 0.

The distance d between the precursor 1 and the isolation plate 302 is smaller than 1/2 of the diameter of the precursor 1, so that the fluid on the isolation plate 302 is acted on by the precursor 1 and moves on the isolation plate 302 at a high speed, so that the fluid pressure on the isolation plate is reduced.

The distance between the precursor 1 and the isolation plate is not limited to 1/2 for the diameter of the precursor 1 in the embodiment, and the fluid on the isolation plate 302 moves at a high speed on the isolation plate 302 under the action of the precursor 1, so that the fluid pressure on the isolation plate is reduced. "are all within the scope of the present invention.

The working principle is as follows:

as shown in fig. 3, the force pressure applied to the power mechanism 1 in the power direction includes:

air pressure F1 acting on the front drive part head-on surface S1,

The air pressure F3 acting on the precursor back flow surface S2,

The air pressure F4 acting on the surface of the isolation plate 302 opposite to the front-part back flow surface S2,

Air pressure F2 acting on the surface of the rear drive.

In summary, the resultant force F of the air applied to the power mechanism is:

F= -F1+F3-F4+F2

when the front drive does not work, air does not flow on the power mechanism, and the vertical height difference of the front drive, the isolation plate and the rear drive is equal to 0, so that F1= F3= F4= F2, and F =0;

when the front drive part is driven by the output shaft of the motor to rotate at a high speed, air on the flow surface of the front drive part 1 and the flow surface of the front drive part 1 move relatively, and the air pressure F1 on the flow surface of the front drive part 1 is reduced according to the Bernoulli law; on the other hand, the air pressure F3 acting on the back flow surface of the precursor 1 is reduced, and the air pressure F4 acting on the partition plate is also reduced; the airflow acting on the rear drive face is unaffected and therefore F4 does not change. Since the variation delta F1\ delta F3\ delta F4 of F1\ F3\ F4 is directly related to the rotating speed of the precursor, and the variation delta F3 is approximately equal to delta F1 or delta F3 is approximately equal to delta F4, F = - (F1-delta F1) + (F3-delta F3) - (F4-delta F4) + F2= (-F1+ F3-F4+ F2) + delta F1-delta F3+ (delta F4= delta F1-F3 + (delta F4) is approximately equal to delta F1 or delta F4 > 0, the aerodynamic force is obtained.

When the front drive rotates at a high speed, the fluid between the front drive and the separation plate is acted by the front drive to do high-speed circular motion and has centrifugal force; because the power mechanism is difficult to realize full sealing, at least one part of fluid between the front drive part and the isolation plate can be thrown out from the space between the front drive part and the isolation plate, so that the air pressure between the front drive part and the isolation plate is reduced, and the front drive part is easy to deform; in this embodiment, the front drive component is sleeved in the bearing, and the bearing is sleeved in the cylinder shell 301, so that the bearing bears the air pressure difference between the flow surface and the back flow surface of the front drive component, thereby protecting the working stability of the front drive component.

In summary, the invention enables the front driving part to move at a high speed, then enables the fluid on the power front driving part and the power front driving part to move relatively, then reduces the pressure of the fluid on the power front driving part, then enables the pressure on the power front driving part to be smaller than the pressure on the power rear driving part, and then enables the aircraft/the water craft/the submersible vehicle to obtain or improve the moving capability (including the acting force of lifting force and/or horizontal movement).

In order to obtain better power effect, the front drive of the embodiment also adopts the following gain technology:

gain scheme 1:

as shown in fig. 4, 5 and 2, the front-drive element 1 has one or more flow storage cavities 10 on the back flow surface, one end of each flow storage cavity 10 is closed, and the other end is open, so that the fluid in the cavity of the flow storage cavity 10 is in fluid communication with the outside; the fluid storage chamber 10 is provided with a fluid escape prevention mechanism, and in this embodiment, the fluid escape prevention mechanism is characterized in that the distance from the open end of the fluid storage chamber 10 to the output shaft 310 of the motor 31 is smaller than the distance from the closed end of the fluid storage chamber 10 to the output shaft 310 of the motor 31, so that in the rotation process of the front drive 1, the fluid in the fluid storage chamber 10 flows to the closed end due to centrifugal force and cannot flow out from the open end.

The flow storage cavity 10 is composed of one or more hollow truncated cones (101, 102, 103 in the present embodiment) with equal wall thickness and one or more partition plates (2 blocks 104, 2 blocks 105, 2 blocks 106, 2 blocks 107 in the present embodiment); the inner diameter of the hollow round table with equal wall thickness towards one end (hereinafter referred to as the lower end) of the separation plate 302 is smaller than the inner diameter of one end (hereinafter referred to as the upper end) of the separation plate 302, the outer diameters of the upper end and the lower end of the partition plate 101 are respectively smaller than the inner diameters of the upper end and the lower end of the partition plate 102, the outer diameters of the upper end and the lower end of the partition plate 102 are respectively smaller than the inner diameters of the upper end and the lower end of the partition plate 103, the partition plate; the partition plates 104, 105 and 106 are uniformly distributed along the diameters of the end parts 101, 102 and 103, and divide each hollow truncated cone with the same wall thickness into 8 equal parts, so as to form 24 flow storage cavities 10.

The working principle is as follows:

as shown in fig. 3, the fluid pressure on the front-drive back-flow surface S2 is reduced by a value Δ F3 to damp the occurrence of power, while the fluid pressure on the surface S3 of the isolation plate 302 facing the front drive is also reduced, and the corresponding fluid pressure reduction value Δ F4 on the surface S3 is increased to gain the occurrence of power; as shown in fig. 4 and 5, since the flow storage cavity is arranged on the front-drive-piece back flow surface, and the upper end (the closed end) of the flow storage cavity is farther from the rotating shaft than the lower end (the open end), the fluid entering from the lower end of the flow storage cavity is pressed towards the upper end by the centrifugal force without flowing away from the flow storage cavity, and then the movement speed close to that of the front drive piece with the flow storage cavity is obtained, namely, the relative movement speed of the fluid on the front-drive-piece back flow surface S2 relative to the back flow surface S2 is close to 0, so that Δ F3 is close to 0; on the other hand, since the partition plate 302 does not rotate, and the fluid on the plate surface S3 of the partition plate 302 rotates under the action of the front drive 1, that is, the fluid on the plate surface S3 of the partition plate 302 moves at a high speed on the surface S3, Δ F4 is greater than 0, Δ F4 is greater than Δ F3, and the power mechanism is improved to obtain power facing the same direction as the incident flow surface.

The back flow surface is provided with a drainage structure (flow storage cavity), so that the capability of synchronous movement of the back flow surface and fluid can be improved, the surface area of the north flow surface is increased, and the pressure drop (pressure reduction value) is improved when the fluid moves relatively. It is therefore necessary to balance this, i.e. to achieve as high a synchronous movement as possible, otherwise a reaction will occur, and the structure of the reservoir perfectly solves this technical problem.

Gain scheme 2:

the gain technique of the front-driver in this embodiment may also adopt the following technical solutions:

and lubricating liquid is filled between the front drive part and the separation plate.

The working principle is as follows:

since the liquid is relatively incompressible and expandable with respect to the gas, it is less likely to overflow between the precursor and the partition plate during high-speed rotation of the precursor, especially when the precursor is moving in a non-circular motion, such as: when the device moves back and forth, the stability is more obvious, namely, the contact between the front part and the isolation plate is better ensured.

Gain scheme 3:

as shown in fig. 6, the front flow surface of the front part is a smooth spherical surface, and the back flow surface is a rough plane.

The working principle is as follows:

the areas of the incident flow surface and the back flow surface are different, and the specific expression is that in a motion period, the sum of the paths passed by all the points of the incident flow surface is greater than the sum of the paths passed by all the points of the back flow surface; since the two surfaces have the same movement speed, the paths of the fluid passing through the respective surfaces are different in unit time, that is, the flow speeds on the two surfaces are different (the flow speed on the incident flow surface is greater than that on the back flow surface), and then the corresponding fluid pressure reduction values are different, specifically, the relative movement speed of the fluid on S1 and S1 is higher than that of the fluid on S2 and S2, and then DeltaF 3 is greater than DeltaF 4, so that the power mechanism obtains the power facing the same direction as the incident flow surface.

Example 2

As shown in fig. 7, the aerodynamic flight device is provided with a plurality of aerodynamic mechanisms, and each aerodynamic mechanism is provided with one or more front drivers 1, a base 3 and a motor 2; the rotating shaft of the front driving part 1 is fixed on the upper end surface of the base 3 through a bearing 10, gears 11 are sleeved on the rotating shaft of the front driving part 1, and the gears 11 on the front driving parts 1 form a transmission link with the gears on the output shaft of the motor 2 through chains 13; the end of the motor is fixed on the base 3 through a bracket. The front part has smooth spherical surface and rough surface. And a partition plate is not arranged between every two front driving parts, so that airflows on the incident surfaces of the adjacent front driving parts can be mutually influenced. There is at least one pair of adjacent two front drive members turning in opposite directions.

The working principle is as follows:

unlike embodiment 1, this embodiment does not satisfy the distance between the front drive and the rear drive (pedestal): the gas on the base moves at a high speed under the action of the precursor, and then the gas pressure on the base is reduced; and no separation plate is arranged between the front driving part and the rear driving part (base); the principle of generating lift force is as follows:

the areas of the incident flow surface and the back flow surface are different, and the specific expression is that in a motion period, the sum of the paths passed by all the points of the incident flow surface is greater than the sum of the paths passed by all the points of the back flow surface; since the two surfaces have the same movement speed, the paths of the fluid passing through the respective surfaces are different in unit time, that is, the flow speeds on the two surfaces are different (the flow speed on the incident flow surface is greater than that on the back flow surface), and then the corresponding fluid pressure reduction values are different, specifically, the relative movement speed of the fluid on S1 and S1 is higher than that of the fluid on S2 and S2, and then DeltaF 3 is greater than DeltaF 4, so that the power mechanism obtains the power facing the same direction as the incident flow surface.

Example 3

As shown in fig. 8, 4 and 5, the aerodynamic aircraft is provided with a plurality of groups of aerodynamic mechanisms, and each aerodynamic mechanism is provided with one or more front drivers 1, a base 3 and a motor 2; the rotating shaft of the front driving part 1 is fixed on the upper end surface of the base 3 through a bearing 10, gears 11 are sleeved on the rotating shaft of the front driving part 1, and the gears 11 on the front driving parts 1 form a transmission link with the gears on the output shaft of the motor 2 through chains 13; the end of the motor is fixed on the base 3 through a bracket. The front driving part 1 has a smooth surface on the flow surface, one or more flow storage cavities 10 are arranged on the back flow surface, one end of each flow storage cavity 10 is closed, and the other end of each flow storage cavity 10 is opened, so that fluid in the cavity of each flow storage cavity 10 is communicated with external fluid; the fluid storage chamber 10 is provided with a fluid escape prevention mechanism, and in this embodiment, the fluid escape prevention mechanism is characterized in that the distance from the open end of the fluid storage chamber 10 to the output shaft 310 of the motor 31 is smaller than the distance from the closed end of the fluid storage chamber 10 to the output shaft 310 of the motor 31, so that in the rotation process of the front drive 1, the fluid in the fluid storage chamber 10 flows to the closed end due to centrifugal force and cannot flow out from the open end.

The flow storage cavity 10 is composed of one or more hollow truncated cones (101, 102, 103 in the present embodiment) with equal wall thickness and one or more partition plates (2 blocks 104, 2 blocks 105, 2 blocks 106, 2 blocks 107 in the present embodiment); the inner diameter of the hollow round table with equal wall thickness towards one end (hereinafter referred to as the lower end) of the separation plate 302 is smaller than the inner diameter of one end (hereinafter referred to as the upper end) of the separation plate 302, the outer diameters of the upper end and the lower end of the partition plate 101 are respectively smaller than the inner diameters of the upper end and the lower end of the partition plate 102, the outer diameters of the upper end and the lower end of the partition plate 102 are respectively smaller than the inner diameters of the upper end and the lower end of the partition plate 103, the partition plate; the partition plates 104, 105 and 106 are uniformly distributed along the diameters of the end parts 101, 102 and 103, and divide each hollow truncated cone with the same wall thickness into 8 equal parts, so as to form 24 flow storage cavities 10.

The working principle is as follows: gain scheme 1 as in example 1.

In the above three embodiments, a "multi-swirl fluid control method" may be adopted to enhance the fluid flow rate, specifically including: a central fluid control method and a circumferential fluid control method; the central fluid control method is to make the central fluid rotate at a high speed in a certain direction, and the surrounding fluid control method is to make the fluid with the central fluid as the central axis rotate at a high speed in the opposite direction of the central fluid, so that the two fluids cooperate to make the controlled fluid form a multi-vortex surrounding effect, and is specifically described by the following embodiments:

example 4

As shown in fig. 9, 10 and 11, the aerodynamic aircraft is provided with one or more groups of aerodynamic mechanisms, and each group of aerodynamic mechanisms is provided with one or more aerodynamic mechanisms; the aerodynamic mechanism comprises a power front drive part 1 and an aerodynamic mechanism 3; the power mechanism 3 comprises a main body 30, a motor 31, a storage battery 32 and a control box 33; the main body 30 comprises a cylindrical shell 301, a separation plate 302 and a drainage plate 303, wherein the separation plate 302 is fixedly arranged in the cylindrical shell 301 and close to one end of the cylindrical shell 301, and the drainage plate 303 is arranged at the open end of the cylindrical shell 301; the motor 31 is fixedly arranged on the isolation plate 302, and an extension part is sleeved at the end part of an output shaft 310 of the motor 31; the extension part is provided with 2 or more air outlet holes 310 in a ring shape at the position between the front drive part 1 and the isolation plate 302; the front driving part 1 is sleeved on the extension part of the output shaft of the motor 31, and is arranged on two sides of the isolation plate 302 together with the motor 31; the extension part passes through the front drive part 1, an air inlet 311 is arranged at the end part of the extension part, and the air inlet 311 is communicated with the air outlet 310.

As shown in fig. 10, the hollow part of the drainage plate 303 is in a circular truncated cone shape, and the diameter D of the upper end part is less than the diameter D of the lower end part;

as shown in fig. 11, a centrifugal blade is disposed on the back flow surface of the front drive 1, and the fluid between the front drive and the partition plate is thrown out from the gap 2 by the centrifugal blade, extruded from the flow guide plate 303, and finally enters the air inlet hole 311, and then reenters the space between the front drive and the partition plate from the air outlet hole 310 to complete a cycle.

It is to be noted in particular that: the circumferential movement speed S2 is less than S3, and the radial movement speed S2= S3, so the resultant speed at S2 is less than the resultant speed at S3. Namely, the air pressure reduction value on the back flow surface of the front drive part is smaller than the air pressure reduction value on the partition plate, so that the acting force of the fluid between the front drive part and the partition plate on the power mechanism has a gain effect.

The embodiment can fully and circularly utilize the kinetic energy of the fluid, so that the fluid can be repeatedly utilized once at least for one time to supply power for the next period, the energy loss after operation is greatly reduced, the power performance of the power mechanism is improved, the energy consumption is low, the environment is protected, and the embodiments can be independently applied and can also be combined and applied.

The following conclusions can be drawn from examples 1 to 4:

1) the rear drive is not necessarily present;

2) the area of the rear driving part is increased, so that a larger gain effect cannot be obtained, and because the non-planar projection area is still the same as that of the front driving part, power cannot be obtained; but the lift force is obtained just because the fluid speeds of the front driving surface and the rear driving surface are different;

3) when the rear driving piece exists, the front driving piece and the rear driving piece cannot be completely sealed, so that certain air is certainly present and is communicated with the air outside the power mechanism, and the back flow surface of the front driving piece is still in the air, so that the damping effect caused by the reduction of the air pressure of the back flow surface of the front driving piece is considered (if the damping effect is not solved, the lifting force cannot be generated at all, and at least the reduction value of the air pressure in the advancing direction is smaller than the reduction value of the air pressure in the advancing reverse direction); it can be seen that the damping effect generated by the reduced air pressure value on the front-drive back flow surface can be overcome by the reduced air pressure value on the surface S. The invention controls the distance between the precursor back flow surface and the surface S, particularly the distance between the precursor back flow surface and the surface S is reduced, so that the air densities on the surface S and the precursor back flow surface are the same, meanwhile, the precursor drives the fluid on the surface S to flow on the surface S, the relative movement speed of the air on the surface S and the surface S is higher than that of the air on the precursor back flow surface and the precursor back flow surface, and the air pressure on the surface S is lower than that on the precursor back flow surface.

4) When present on the rear drive face, the pressure change value is close to 0 because the fluid on the rear drive face does not move relative to the rear drive face.

Example 5

An aerodynamic aircraft as shown in fig. 11 is provided with a front drive part 1 'and an assembly chamber 2'; in the advancing direction of the power mechanism, the rear driving part 2 ' is arranged in a cavity of the assembly chamber 2 ', the upper end face of the assembly chamber 2 ' is hollowed out, so that the flow facing surface of the front driving part 1 ' directly contacts with air, the linear motor 3 ' is fixed at one end of the assembly chamber 2 ', and the output shaft of the linear motor 3 ' is connected with and drives the front driving part 1 ', so that the front driving part 1 ' moves backwards in the assembly chamber 2 ', the air in the hollowed-out position of the assembly chamber 2 ' and the flow facing surface of the front driving part 1 ' move relatively, and the air pressure on the flow facing surface of the front driving part 1 ' is reduced.

The space in the assembly chamber 2 'except the front component 1' is filled with lubricating liquid.

Examples 1 to 5 may each prefer the following:

the power front driving part is provided with a plurality of areas, and the steering of the power device in the space is adjusted by controlling the fluid speed of at least 2 positions on the same power front driving part.
