Upper and lower double-ducted jet-type pipeline ultra-high-speed flying car operation method and operation system

Abstract

The present invention relates to the field of rail transit technology, and more particularly to an upper and lower dual-duct jet-type duct super-high-speed flying car operating method and operating system. During intake, the flying car's head propeller compresses most of the incoming air from the front of the car in the upper duct through the intake channel to the lower duct. A small portion of the airflow at the front of the car is compressed through the intake channel to the lower duct by the action of the deflector on the flying car body and the body propeller. During compression, the flying car's bottom propeller compresses the airflow through the intake channel to the pressure chamber of the lower duct at the bottom of the flying car. During jet discharge, the dynamic sealing state of the pressure chamber of the lower duct at the rear of the flying car is broken, and the high-pressure airflow in the lower duct is ejected from the air outlet channel along the rear of the flying car to the upper duct. The flying car's tail propeller guides the airflow to the rear of the car body, realizing the flying car's jet-type super-high-speed operation in the duct. The construction of the upper and lower dual ducts within the duct effectively organizes the airflow, reduces the flying car's running resistance, and improves the operating efficiency of the super-high-speed flying car.

Description

Technical Field

[0001] The present invention relates to the field of rail transportation technology, and in particular to an operation method and an operation system for an upper and lower double-duct jet-type pipeline ultra-high-speed flying car. Background Art

[0002] The development of ultra-high-speed flying cars mainly needs to solve two major problems: reducing resistance and controlling noise. The current solution is to eliminate wheel-rail friction resistance and reduce aerodynamic resistance through low-vacuum tube magnetic levitation electromagnetic propulsion technology. The noise can be controlled inside the tube through tube constraints, greatly reducing the noise impact along the line. However, at the same time, the low-vacuum tube weakens the aerodynamic effect and greatly increases the cost expenditure in many aspects such as tube construction, low-vacuum maintenance, and later maintenance. The low-vacuum tube has many unfavorable conditions for escaping in distress, emergency rescue, and daily inspection and maintenance. There are also many technical difficulties in powering the ultra-high-speed vehicle body, and the use of battery storage will cause weight problems.

[0003] In response to the above problems, the present invention proposes an upper and lower double-ducted jet duct ultra-high-speed flying car operation method and operation system that does not require low vacuum and magnetic levitation electromagnetic propulsion technology, and achieves jet ultra-high-speed flight through upper and lower double-ducted air flotation and aerodynamics under conventional atmospheric pressure. Summary of the Invention

DETAILED DESCRIPTION

[0058] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0059] In this description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediary, or internal connections between two components. Those skilled in the art will understand the specific meanings of these terms based on the specific circumstances.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all the embodiments.

[0061] The present invention provides a method for operating an ultra-high-speed flying car using an upper and lower double-ducted jet-jet pipeline, which is specifically as follows:

[0062] S1: If Figure 20 As shown, the space inside the pipeline 1 is divided into upper and lower ducts by the bottom plate 101. The lower duct below the bottom plate 101 is divided into multiple pressure chambers by the partition 102. The flying car 2 runs in the upper duct. The bottom plate 101 is provided with an air intake channel and an air outlet channel connecting the pressure chamber and the upper duct along the running direction.

[0063] S2: The operation method includes suction, compression, and ejection (such as Figure 10 and 23 shown);

[0064] During air intake, the head propeller 202 of the flying car 2 compresses most of the airflow from the front of the vehicle in the upper duct through the air intake channel to the lower duct. A small portion of the airflow from the front of the vehicle is compressed through the air intake channel to the lower duct by the deflector 203 on the body of the flying car 2 and the body propeller 204. The airflow in the gap between the top of the flying car 2 and the duct 1 is constrained by the gap and is always in a laminar state (because there are no spatial conditions for the formation of eddy turbulence).

[0065] During compression, the bottom propeller 205 of the flying car 2 compresses the airflow through the air intake channel into the pressure chamber of the lower duct at the bottom of the flying car 2. The power provided by the bottom propeller 205 replenishes the energy loss during the flow of the airflow and keeps the pressure chamber of the lower duct in a dynamic sealing state.

[0066] During jetting, the dynamic sealing state of the pressure chamber of the lower duct at the rear of the flying car 2 is destroyed, and the high-pressure airflow in the lower duct is ejected from the air outlet channel along the rear of the flying car 2 to the upper duct, and the tail propeller 206 of the flying car 2 guides the airflow to the rear of the car body 201, realizing the jet-like ultra-high-speed operation of the flying car 2 in the pipeline 1.

[0067] In the present invention, the incoming flow is equivalent to the air flow, and specifically refers to the air flow toward the front portion of the flying car 2. The air intake channel and the air outlet channel can be the same channel or different channels. The air intake channel and the air outlet channel can also be a single channel or multiple channels.

[0068] In the non-operating state, the interior of the pipeline 1 of the present invention is in a normal pressure environment, thereby solving the technical difficulties and financial expenditure problems existing in low vacuum pipelines.

[0069] In the present invention, as the airflow around the vehicle body is directed by deflector 203, deflector 203 and the vehicle body propeller 204 utilize boundary layer entrainment technology to alter the turning point of the airflow as it flows through the vehicle body, ensuring that the airflow maintains orderly laminar flow throughout its compression into the lower duct. When flying car 2 disturbs the airflow within duct 1, the airflow within duct 1 remains relatively static. When flying car 2 is in operation, the airflow in the gap between the top of flying car 2 and duct 1 is constrained by the gap. This constrained, laminar airflow forms an air film on the surface of the flying car.

[0070] During the intake process, the airflow at the front of the flying car 2 is introduced into the lower duct, so the airflow pressure at the front of the flying car 2 decreases; during the compression process, the airflow pressure in the lower duct increases; during the ejection process, the airflow pressure at the rear of the flying car 2 increases, so that there is a pressure difference between the front and rear of the flying car 2 during the entire process, and the pressure at the rear of the flying car 2 is higher than that at the front of the flying car 2; there is a pressure difference between the bottom and the top of the car body 201, and the pressure at the bottom of the car body 201 is higher than that at the top of the car body 201.

[0071] The lift-to-drag ratio of the flying vehicle 2 in the pipeline 1 is estimated as follows:

[0072] The dimensions and load capacity of Flying Car 2 are as follows: 2.5m high, 3m wide, 10t deadweight, 100 passengers, and 20t fully loaded. When Flying Car 2 is operating in a self-steady state, the lift force L is balanced with the fully loaded gravity G, i.e.:

[0073] L=G=Mg=20000kg*9.8N / kg=196000N

[0074] In the self-steady state, the flying car 2 is in a stable state, and the resistance and aerodynamic force are balanced. The aerodynamic force of the flying car 2 is provided by the pressure difference between the front and rear of the car body 201. Since the cross-sectional area of ​​the flying car 2 is an irregular shape, the cross-sectional area S is estimated to be 7m 2 The atmospheric pressure difference ∆p before and after the vehicle is 0.01 bar. The power F generated by the pressure difference ∆P is: F=∆PS, and the power F is numerically equal to the resistance D, that is, F=D; the resistance D is:

[0075] D=F=∆pS=0.01bar*7m2 =0.01*101325Pa*7=7092.75N

[0076] The lift-to-drag ratio is:

[0077] K=L / D=27.6339≈28

[0078] When the lift provided by the head propeller 202, the deflector 203, the body propeller 204, and the bottom propeller 205 is greater than the gravity when fully loaded, the flying car 2 moves upward in the upper duct, the sealing effect of the pressure chamber in the lower duct is weakened, and the pressure decreases, causing the flying car 2 to gradually move downward. During the downward movement, the sealing effect of the pressure chamber in the lower duct is strengthened, and the pressure increases, causing the flying car 2 to gradually move upward. The flying car 2 gradually reaches a self-stable operating state during the upward and downward adjustment process. In order to improve the self-stable operating state of the flying car 2 in the pipeline 1, in the present invention, the pressure chambers divided by the partition 102 are all pressure chambers of the same structure and size; and the pipeline 1 in the present invention is a pipe body of equal diameter.

[0079] In order to enhance the starting (equivalent to the flying car 2 going uphill) and braking (equivalent to the flying car 2 going downhill) of the flying car 2 in the pipeline 1, in the present invention, preferably, a high-pressure pressure tank is installed in the lower duct of the pipeline 1. When the rear end of the flying car 2 is located in front of the high-pressure pressure tank, the high-pressure pressure tank starts to discharge high-pressure gas, increasing the pressure at the rear end so that the car body 201 can achieve the effect of accelerating uphill or accelerating starting; a low-pressure pressure tank is installed in the lower duct of the pipeline 1. When the rear end of the flying car 2 travels behind the low-pressure pressure tank before going downhill or braking, the low-pressure pressure tank at the bottom starts to discharge low-pressure gas, reducing the pressure at the front end of the flying car 2, so that the flying car 2 can achieve the effect of slowing down downhill or slowing down braking.

[0080] When the flying car 2 tilts to the left in the pipe 1, the propeller 204 of the car body is adjusted, the air pressure on the left side increases and the air pressure on the right side decreases, and the car body 201 deflects to the right. After deflecting to the right, the air pressure on the left side decreases and the air pressure on the right side increases, causing the car body 201 to tilt to the left and gradually reach a stable position.

[0081] When the car 2 tilts to the left in the pipe 1, the volume of the space between the left side of the car 2 and the inner wall of the pipe 1 decreases, the pressure increases, the volume of the space between the right side of the car 2 and the inner wall of the pipe 1 increases, the pressure decreases, and the car 2 will deflect to the right; when the car 2 deflects to the right, the volume of the space between the right side of the car 2 and the inner wall of the pipe 1 decreases, the pressure increases, the volume of the space between the left side of the car 2 and the inner wall of the pipe 1 increases, the pressure decreases, and the car 2 will deflect to the left, and this cycle continues until the volume of the space on the left and right sides of the car 2 is gradually equal, that is, the pressure on the left and right sides is equal, and a stable state is reached.

[0082] The specific embodiments of the present invention are described in detail below. The various angles mentioned in the present invention can be measured and calculated by those skilled in the art using aerodynamics based on the actual size of the vehicle body 201 . Example 1

[0083] The present invention provides an upper and lower double-ducted jet-jet pipeline ultra-high-speed flying car operation system capable of realizing the above-mentioned operation method, comprising a pipeline 1 and a flying car 2;

[0084] The pipeline 1 includes a bottom plate 101 disposed within the pipe body and dividing the space within the pipeline 1 into upper and lower ducts. The lower duct below the bottom plate 101 is divided into multiple pressure chambers by a partition 102. The edge of the bottom plate 101 is sealed with the pipe body of the pipeline 1, and a first opening 103 is provided in the middle of the bottom plate 101 along the running direction to allow air in and out. The first opening 103 also serves as an air intake channel and an air outlet channel connecting the pressure chamber and the upper duct.

[0085] The flying car 2 includes a car body 201 that is parallelogram-shaped when projected from the side and semicircular when projected from the front. When viewed from above, the width of the front tip of the car body 201 gradually widens and transitions to the car body, and the width of the rear of the car body 201 gradually decreases from the car body. The front tip of the car body 201 is located at the lower part of the car body 201. Two head propellers 202 are symmetrically arranged side by side in the middle of the front of the car body 201, and two tail propellers 206 are symmetrically arranged side by side in the middle of the rear of the car body 201. A plurality of deflectors 203 are arranged side by side along the front-to-back direction on the side of the car body 201. A deflection gap is formed between the plate body of the deflector 203 and the surface of the car body 201. The connection between the plate body of the deflector 203 and the surface of the car body 201 gradually tilts toward the rear of the car from top to bottom (such as Figure 1 As shown in FIG, the width of the guide plate 203 gradually widens from top to bottom, the air flow inlet of the guide gap faces the front of the vehicle body 201, and the width of the guide gap gradually widens from top to bottom; at least two body propellers 204 are provided in the guide gap, and two rows of bottom propellers 205 are provided side by side at the bottom of the vehicle body 201 in the front-to-back direction, and the width of the vehicle body 201 occupied by the two rows of bottom propellers 205 is adapted to the first opening 103 (as shown in FIG. Figure 11 shown).

[0086] like Figures 1 to 4 As shown, in this embodiment, a first arc-shaped concave surface 209 is provided between the front tip and the blunt part of the vehicle body 201 for cooperating with the incoming flow guide, and a second arc-shaped concave surface 210 is provided between the rear tip and the blunt part of the vehicle body 201 for cooperating with the high-pressure airflow guide in the lower duct.

[0087] like Figure 10As shown in (a), when inhaling, the head propeller 202 of the flying car 2 compresses most of the airflow at the front of the car in the upper duct through the air intake channel to the lower duct; a small part of the airflow at the front of the car is guided to the air intake channel by the guide plate 203 on the body of the flying car 2. Specifically: after the airflow enters through the airflow inlet of the guide gap, it extends downward and backward along the guide gap, is guided by the body propeller 204, and then passes through the airflow outlet of the guide gap (the bottom of the guide plate 203) and is guided to the air intake channel (i.e., the first opening 103) by the bottom propeller 205, and then enters the pressure chamber in the lower duct.

[0088] Furthermore, the present invention provides a specific embodiment of the head propeller 202: Figure 1 As shown, the two head propellers 202 are both symmetrical two-blade forward and reverse propellers, and the planes where the propeller bodies of the two head propellers 202 are located are located in the same plane, the planes where the propeller bodies of the two head propellers 202 are located are perpendicular to the length direction of the vehicle body 201, and the planes where the propeller bodies of the two head propellers 202 are located are perpendicular to the base plate 101.

[0089] like Figure 10 As shown in (b), during compression, the bottom propeller 205 of the flying car 2 compresses the airflow from the front and part of the body of the flying car 2 through the air intake channel into the pressure chamber of the lower duct at the bottom of the flying car 2. In order to facilitate the guidance of the airflow to the air intake channel, this embodiment also provides a specific structure of the bottom propeller 205: two rows of bottom propellers 205 are symmetrically arranged at the center of the bottom of the car body 201, and the planes where the propeller bodies of the bottom propellers 205 in the same row are located are located in the same plane, and there is an angle between the planes where the propeller bodies of the two rows of bottom propellers 205 are located. The angle between the planes where the propeller bodies of the two rows of bottom propellers 205 are located is narrow at the top and wide at the bottom (as shown in FIG. Figure 5 shown).

[0090] Specifically, from the right side of the flying car 2, the airflow compressed into the lower duct pressure chamber flows from top to bottom, from front to back, and from bottom to top (clockwise); Figure 11 As shown, from the rear angle of the flying car 2, the airflow compressed into the lower duct pressure chamber presents a flow from top to bottom (from the center of the intake channel to the side wall of the pressure chamber), from bottom to top along the side wall of the pressure chamber, and from the side wall of the pressure chamber to the center of the outlet channel.

[0091] During jetting, since there is no bottom propeller 205 at the rear of the flying car 2, the dynamic sealing state of the pressure chamber of the lower duct at the rear of the flying car 2 is destroyed, and the high-pressure airflow in the lower duct is ejected from the air outlet channel along the rear of the flying car 2 to the upper duct, and the tail propeller 206 of the flying car 2 guides the airflow to the rear of the car body 201, realizing the jet-like ultra-high-speed operation of the flying car 2 in the pipeline 1.

[0092] Furthermore, the present invention provides a specific embodiment of the tail propeller 206: the two tail propellers 206 are both symmetrical two-blade forward and reverse propellers, and the planes where the propeller bodies of the two tail propellers 206 are located are located in the same plane, there is an angle between the plane where the propeller bodies of the two tail propellers 206 are located and the base plate 101, and the lower parts of the propeller bodies of the two tail propellers 206 are tilted toward the front of the vehicle body 201.

[0093] In this embodiment, preferably, the vehicle body 201 (the rectangular area located in the middle of the parallelogram) has a total length of 20 m, a height of 2.5 m, and a width of 3 m.

[0094] To enhance the safety of the flying car 2 during emergencies such as emergency landings, in this embodiment, two rows of wheels 207 are arranged side by side along the front-to-back direction at the bottom of the car body 201. The bottom plate 101 near the first opening 103 is tilted downward toward the center of the first opening 103, and the two rows of wheels 207 can support and cooperate with the inclined portion of the bottom plate 101. In this embodiment, the tilt of the bottom plate 101 can constrain the two rows of wheels 207, forcing the car body 201 to travel along the centerline of the bottom plate 101, avoiding collisions with the sidewalls of the pipeline 1 due to angles, and greatly improving safety. In this embodiment, the wheels 207 serve only to provide support and guidance for the car body 201. The wheels 207 and the bottom plate 101 are in a rolling relationship, and no power traction is required. Preferably, the wheels 207 in this embodiment are made of lightweight materials.

[0095] In order to facilitate the provision of power for various propellers and other components on the flying car 2, in this embodiment, the storage battery can be placed at the bottom of the car body 201, making full use of the car body space and facilitating the heat dissipation of the battery in the working state. Example 2

[0096] The present invention provides another specific embodiment of an upper and lower double-ducted jet-jet pipeline ultra-high-speed flying car operation system, comprising a pipeline 1 and a flying car 2;

[0097] The duct 1 includes a bottom plate 101 disposed within the duct body and dividing the space within the duct 1 into upper and lower ducts. The lower duct below the bottom plate 101 is divided into multiple pressure chambers by a partition 102. The gap between the edge of the bottom plate 101 and the duct body of the duct 1 forms an air intake channel connecting the pressure chambers and the upper duct. A second opening 104 is provided in the middle of the bottom plate 101 along the running direction, allowing air to flow from the pressure chamber to the upper duct. The second opening 104 serves as an air outlet channel connecting the pressure chambers and the upper duct.

[0098] The flying car 2 includes a car body 201 that is parallelogram-shaped when projected from the side and semicircular when projected from the front. When viewed from above, the width of the front tip of the car body 201 gradually widens and transitions to the body, and the width of the rear of the car body 201 gradually decreases from the body. The front tip of the car body 201 is located at the lower part of the car body 201. Two head propellers 202 are symmetrically arranged side by side in the middle of the front of the car body 201, and two tail propellers 206 are symmetrically arranged side by side in the middle of the rear of the car body 201. A plurality of deflectors 203 are arranged side by side along the front-to-back direction on the side of the car body 201 to guide the vehicle. The connection between the plate body of the deflector 203 and the surface of the vehicle body 201 gradually tilts toward the rear of the vehicle from top to bottom, and the width of the connection between the plate body of the deflector 203 and the surface of the vehicle body 201 gradually decreases from top to bottom. The guide surface formed by the plate body of the deflector 203 gradually increases from top to bottom. At least one body propeller 204 is provided in front of the vehicle body 201 corresponding to the deflector 203, and a row of bottom propellers 205 are respectively provided at the bottom of the vehicle body 201 outside both sides of the vehicle body 201 along the front and rear directions. The two rows of bottom propellers 205 are respectively located in the intake channel.

[0099] like Figures 13 to 16 As shown, in this embodiment, a first arc-shaped concave surface 209 is provided between the front tip and the blunt part of the vehicle body 201 for cooperating with the incoming flow guide, and a second arc-shaped concave surface 210 is provided between the rear tip and the blunt part of the vehicle body 201 for cooperating with the high-pressure airflow guide in the lower duct.

[0100] like Figure 23 As shown in (a), when inhaling, the head propeller 202 of the flying car 2 compresses most of the incoming flow at the front of the car in the upper duct through the intake channel to the lower duct; a small part of the airflow at the front of the car is guided to the intake channel by the guide plate 203 on the body of the flying car 2. Specifically, the airflow is guided to the guide plate 203 through the body propeller 204, and the airflow extends downward along the downward and rearward guide surface of the guide plate 203, and then is guided by the bottom propeller 205 to the gap between the bottom plate 101 and the pipe 1, and then enters the pressure chamber in the lower duct.

[0101] Furthermore, this embodiment provides a specific embodiment of the head propeller 202: Figure 1 As shown, the two head propellers 202 are both symmetrical two-blade forward and reverse propellers, and the planes where the propellers of the two head propellers 202 are located are located in the same plane, and there is an obtuse angle between the plane where the propellers of the two head propellers 202 are located and the forward direction of the vehicle body 201.

[0102] like Figure 23As shown in (b), during compression, the bottom propeller 205 of the flying car 2 compresses the airflow from the front and the body of the car through the air intake channel into the pressure chamber of the lower duct at the bottom of the flying car 2. In order to facilitate the airflow to the air intake channel, this embodiment also provides a specific structure of the bottom propeller 205 (such as Figure 19 (as shown): Two rows of bottom propellers 205 are symmetrically located on the outside of the bottom of the vehicle body 201. The planes on which the propellers of the two rows of bottom propellers 205 are located are located in the same plane and are parallel to the bottom plate 101. In this embodiment, one-third of the propellers of the bottom propellers 205 are located on the bottom of the vehicle body 201, and two-thirds of the propellers are located outside the vehicle body 201.

[0103] Specifically, when viewed from the right side of the flying car 2, the airflow compressed into the lower duct pressure chamber flows from top to bottom, from front to back, and from bottom to top (clockwise); Figure 24 As shown, viewed from the rear of the flying car 2, the airflow compressed into the lower duct pressure chamber extends from the top of the side wall of the pressure chamber downward along the side wall, and from the center of the bottom of the pressure chamber upward to the center of the air outlet channel.

[0104] During jetting, since there is no bottom propeller at the rear of the flying car 2, the dynamic sealing state of the pressure chamber of the lower duct at the rear of the flying car 2 is destroyed, and the high-pressure airflow in the lower duct is ejected from the air outlet channel along the rear of the flying car 2 to the upper duct, and the tail propeller 206 of the flying car 2 guides the airflow to the rear of the car body 201, realizing the jet-like ultra-high-speed operation of the flying car 2 in the pipeline 1.

[0105] Furthermore, the present invention provides a specific embodiment of the tail propeller 206: the two tail propellers 206 are both symmetrical two-blade forward and reverse propellers, and the planes where the propeller bodies of the two tail propellers 206 are located are located in the same plane, and there is an obtuse angle between the plane where the propeller bodies of the two tail propellers 206 are located and the forward direction of the vehicle body 201.

[0106] In this embodiment, in order to cooperate with the aerodynamic structure of the rear end of the flying car 2 and guide the airflow to the rear end, as shown in FIG. Figure 18 As shown, the flying car 2 of this embodiment is provided with a tail deflector 208 along the length direction at the middle of the rear of the car. The tail deflector 208 can divert the high-pressure airflow ejected from the air outlet channel of the pressure chamber, and the diverted airflow is guided to the rear of the car by the corresponding tail propeller 206.

[0107] Preferably, two rows of wheels 207 are arranged side by side along the front-to-back direction at the bottom of the vehicle body 201, and the two rows of wheels can respectively cooperate with the bottom plate 101 on both sides of the second opening 104. In this embodiment, since the air intake channel and the air outlet channel are different channels, there is no need to set an inclined structure in the middle of the bottom plate 101 to constrain and cooperate with the wheels 207. However, in order to avoid friction between the vehicle body 201 and the bottom plate 101 during the lifting process, the vehicle body 201 of this embodiment is also provided with wheels 207, and in this embodiment, the wheels 207 only play a supporting role and do not require power traction. Figure 17 As shown, one-third of the wheel body of the wheel 207 in this embodiment is located outside the vehicle body 201.

Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art should understand that they may still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and such modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the embodiments, and they should all be included in the scope of protection of the claims.
