Abstract

PURPOSE:To reduce the weight of a vehicle and to improve energy efficiency, by a method wherein a flying vehicle device is floated by means of the lift of a wing and a lift generated by a ground effect, and it is flied in a given height position above a runway for the exclusive use by means of the propulsive force of a flying body. CONSTITUTION:When a power is applied on a motor fan 24 for transmission rotation, a vehicle (flying body) 21 is started to run on a lower runway 14 by means of wheels 31. When a speed is increased to a high value of at least about 120km/H, a lift based on a wing theory and a ground effect is exerted on wings 22a1-22b2, and the flying body is flied in a state to hold a height of about 30cm from runways 14 and 15. The lateral position of the flying body 21 is regulated by a ground effect on a support wall 11a of a wing control plate 33, and by steering the direction radar of a vertical tail assembly 23, stable flying can be continued. This constitution enables reduction of the weight of a vehicle serving as a high speed land traffic means, improves energy efficiency, and enables reduction of the generation of noise due to non-contact running.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is directed to the theoretical lift of the wing and the ground effect.
The present invention relates to a flying vehicle device that has a flying main body equipped with wings that utilize lift force (ffect) and flies at a predetermined height on a dedicated running path.

<Conventional technology and its problems> Currently, high-speed railway vehicles that use electric motors, or so-called Shinkansen vehicles, have wheels that rotate on the rails through contact friction, so there is a speed limit, and it is necessary to ensure contact friction force. Therefore, the weight of the vehicle must be increased, the energy efficiency is poor, and the noise is large.

A superconducting magnetically levitated linear motor car is being researched and developed as an alternative high-speed vehicle. So far, a prototype model has been running and we are aiming for practical use, but since the use of superconductivity is essential for linear motors, the weight of the vehicle is large, and the power consumption to maintain a low temperature is considerable, making it uneconomical. When you think about it, it cannot be said that the outlook is necessarily bright.

On the other hand, although aircraft, which are air transportation, have advantages over railways in terms of speed and economy, they require vast runways, which means that the distance from airports to city centers is long, and the resulting traffic Considering the inconvenience of transportation and the unavoidability of a hopeless situation in the event of an accident, it is difficult to say that this also has a bright future, especially as land transportation.

This trend is particularly noticeable in countries like Japan, where it is difficult to secure land for runways.

The present invention replaces the conventional concept of track-based vehicles, which requires a certain amount of weight in order to achieve high speed, and replaces the concept of aircraft with land-based vehicles, which aims to reduce weight to the utmost in order to increase energy efficiency and obtain speed. This project proposes a new land transportation system that can be applied to moving vehicles to increase speed, improve energy efficiency, reduce noise, and further improve safety.

Means for Solving the Problems> In order to achieve the above object, the present invention provides a dedicated running path;
a vehicle that is guided by the travel path and flies on the travel path using a ground effect; A wing that uses theoretical lift force and ground effective lift force, propulsion means and braking means for the flight main body, and vehicle support means that supports the vehicle at a position above the running road at least in the low thrust region of the propulsion means. The present invention provides a flying vehicle device having the following characteristics.

In order to achieve high-speed driving with energy efficiency, weight reduction is an absolute requirement, and at speeds of 100 km/h or higher, aerodynamic forces (lift, drag) exert a large effect on the vehicle, making it difficult to drive at high speeds. It can be said that not using that lift force in a vehicle is wasting a treasure. By reducing the weight and using lift, there is no need to use the energy of magnetic levitation at speeds above about 250 km/h. Moreover, when the wing is within about 30 cm of the ground surface, the lift is further improved, e.g. by about 30%, which is the so-called ground effect (G
round effect). In the present invention, the vehicle is lifted off the road surface while the vehicle is running by using the above-mentioned lifting force and the ground effect.

In other words, as shown in Figure 3, when a wing is in a flow, the pressure on its upper side (Pu) is theoretically lower than that on its lower side (Pe), resulting in a bending lift force against the flow U. . A wing is a device that generates this force.

Furthermore, as shown in Fig. 4, when the wing 1 is at a height h relative to the ground (or water surface) 2, the pressure Peg on its lower side becomes larger (Peg>Pe), and as a result, t, g> L
This generates a large lift force (high lift force).

As shown in Figure 5, the size is such that wing 1 is on the ground 2
The property of increasing inversely as it approaches (ground effect:
Ground Effect). The wing cross-sectional shape makes it possible to obtain a wing with good ground effect characteristics (FIG. 5b). Here, a wing with good ground effect characteristics is a wing having a cross-sectional shape that becomes larger at a predetermined height h from the ground.

In the present invention, a substantially flat dedicated running path is provided to obtain such a ground effect of the wing. A flight main body as a passenger car or a freight car is placed on the running path, and at least one pair of wings extending to the left and right of the flight main body are provided on the running path. When the flight main body travels on the road at high speed by the propulsion means, the above-mentioned large true lift force and ground effect lift force are generated from around 1100 km/h, for example, and the flight main body floats onto the road.

Now, when the wing is at a height h above the running path, the lift force (floating blade) is P (see Figure 6), and for some reason the wing curls,
Assuming that the lift force increases to Pl, the ground effect principle acts in such a direction that the wing returns to the position h due to the weight of the vehicle. Further, if the height h decreases to h2, the lift force rapidly increases to P2, and it also tries to return to the height h. Therefore, the lift force due to the ground effect acts to always move the wing position toward a certain stable position. In this way, the flying main body is made to float on the traveling path by using the theoretical lift force of the wings and the lift force due to the ground effect, and is driven at high speed by the propulsion means and braked by the braking means. In the low thrust region, the lift force decreases, so the vehicle is supported by the vehicle support means.

Here, it is sufficient that the dedicated running path is approximately flat, and there is no need to make it uniformly smooth. The dedicated travel path may be partially discontinuous or may be on the water surface.

The flight body is made of a material that resembles an aircraft and can be extremely lightweight, such as duralumin for aircraft, or a new material developed in recent years such as carbon fiber, and is formed into a wing-shaped fuselage shape. The same applies to the wing material.

It is sufficient to have at least one pair of wings on both the left and right sides of the flight body, but if two or more pairs of so-called comb-shaped wings are used, the wing length can be shortened, and the running path width can be shortened.

The wing area can be reduced by making the wings compound.

As the propulsion means for the flight main body, an electric fan that obtains electric power from the running road via a pantograph, a turbo fan using aviation materials, etc. may be used, or a near motor or a turbo jet may be used depending on the case.

The braking means for the flight main body is an elevator or spoiler provided on the trailing edge of the wing to assist the rising and descending movements of the flight main body, and furthermore, means for supporting the vehicle at a position above the running road at least in the low thrust region. If the propulsion means are wheels, wheel disc brakes can be used, and if the propulsion means is a linear motor, electromagnetic braking can be used.

As means for supporting the vehicle at a position above the traveling road at least in the low thrust region, in addition to the above-mentioned direct support type wheels (which may be retractable), a floating support method using electromagnetic force, etc. are used.

<Example> The present invention will be explained in detail below.

In one embodiment shown in FIGS. 1A and B and FIG. 2,
A vehicle 12 that flies using the ground effect is arranged on a dedicated running path 11.

Running route 11 can be created by improving the existing Shinkansen running track.
It has a lower running path 14 and an upper running path 15 supported by supporting legs 13. The upper surface of the demarcated route 14.15 is the vehicle 12
When the wing flies, it is formed into a substantially flat surface that is substantially parallel to the lower surface of the wing. As shown in FIG. 7, embedded electric wires 16 are buried in the running path 14.15 along the direction of vehicle travel, and a pantograph 17 electrically connected to the vehicle 12 is pressed onto the embedded electric wires 16. Electric power is drawn into the vehicle 12 by sliding contact due to the pressing force of the spring 18.

The vehicle 12 mainly includes a flight main body 21, two pairs of front and rear biplane wings 22a to 22d extending from the main body 21 to the left and right sides, and an electric fan 24 provided at the rear end of the vertical stabilizer 23. The electric fan 24 is a means of propulsion for the flight main body 21,
At the same time, when functioning as a spoiler, it also functions as part of the braking means.

The thrust of the electric fan 24 is automatically controlled in a central control room via an embedded electric wire 16.

The blade angles of the blades 22a to 22d can be adjusted freely, and the angles of the elevators 26a to 26d provided at their rear edges can also be adjusted freely.

A rudder 27 is provided on the trailing edge of the vertical tail 23 so that its angle can be adjusted freely.

Drooping wheels 31 are provided on the lower surface of the flight main body 21 so as to be freely retractable, and constitute vehicle support means for supporting the vehicle 12 at a predetermined position on the running path 14.15 when the thrust is in a low range. There is. The wheels 31 are retracted while the vehicle 12 is in flight.

The flight main body 21 or the supporting legs of the wheels 31 are provided with an upper running path 1.
A wheel 32 (or a mechanical limiter) is provided opposite the opposing inner end of the upper running path 15, and when the vehicle 12' deviates excessively from a predetermined direction in the lateral direction, the wheel 32 and the inner end surface of the upper traveling path 15 are This deviation is regulated by contact. However, such lateral position control is mainly performed on the upper and lower running paths 14.1.
An airfoil control plate 3 is installed at the outer end of the biplane lower wings 22a+, 22b+, opposing the inner surface of the support wall 11a that supports the outer side of the wing 5.
3 is disposed, and by utilizing the so-called ground effect on the inner surfaces of the support walls 11a of the left and right airfoil control plates 33, the flight main body 21 can fly over a predetermined position on the travel path 14, 15.

Incidentally, the flight body 21 and the single members 22a to 22d, 23 are each made of a lightweight aircraft material.

The operation of the above configuration will be described next.

The electric power introduced via the embedded electric wire 16 and the pantograph 17 is controlled by a central control room to control the starting power of the electric fan 24, the blade angle of the blades 22a to 22d, and the elevator 26.
a to 26d and the steering angle of the rudder 27, storage of the wheels 31,
Performs a protruding action. Various sensors for such control are not shown.

When the vehicle 12 is currently stopped, the vehicle 12 is supported on the lower running path 14 via the wheels 31.

When electric power is applied to the electric fan 24 to rotate it at high speed for departure, the vehicle 12 receives thrust and starts running. When the vehicle 12 reaches a high speed region of about 120 km/h or more,
A lift force based on the true theory and a lift force based on the ground effect act on the single bodies 22a to 22d, causing the flight body 21 to move along the travel path 14.
15 While maintaining the height of the upper wing to approximately 30 cm, move vehicle 1.
Fly 2. At this time, the vertical position of the single members 22a to 22d is maintained at a predetermined value due to the above-mentioned effect of the lifting force based on the ground effect. Just in case, the lower wing 22a of the biplane
A roller may be provided on the upper surface to safely restrict excessive floating of the vehicle 12 by contact with the lower surface of the upper traveling path 15. However, in this embodiment, when the vehicle 12 floats excessively, the contact between the pantograph 17 and the embedded electric wire 16 is cut off, so the driving force of the electric fan 24 is lost, the thrust is insufficient, and the vehicle 12 descends. There is no risk of excessive levitation of the vehicle.

In order to safely levitate the vehicle 12 at the time of departure, the wings 22a to 2
2d, or the elevators 26a to 26d.
can be used to quickly levitate.

While the vehicle 12 is in flight, it is possible to continue more stable flight by steering the rudder 27 and adjusting the steering angles of the elevators 26a to 26d. When flying a vehicle, there is no need to load fuel like an aircraft, and there is no need for a pressure-resistant structure like an aircraft, making the materials lighter and overall extremely lightweight. Since the lifting force based on the ground effect and the true theory is used, there is little energy loss, high efficiency is achieved, and since the vehicle does not come into contact with other objects, noise reduction can be achieved.

Since the blades 22a to 22d have two pairs (comb-shaped blades) at the front and rear and are biplane, the blade length and blade area can be reduced, and the blade structure does not need to be made high in strength, which also contributes to weight reduction. Furthermore, since there is no need to increase the track width, the conventional elevated track for Japan's Shinkansen can be improved to create a two-tiered round trip route.

In order to stop the vehicle 12, the angle of the wings 22a to 22d,
The steering angles of the elevators 26a to 26d are controlled, and the wheels 3
1 to protrude, and at the same time reduce the driving force of the electric fan 24. As a result, the traveling speed of the vehicle decreases, the lift force of the wings also decreases, the vehicle is decelerated, and the vehicle lands via the wheels 31. Here, as braking means, elevators 26a to 26d, wheels 31
This includes a disc brake installed in the engine, a reversing device for the electric fan 24, etc.

In addition to the embodiments described above, a beam near motor can be used as the vehicle propulsion means, and in this case, as the vehicle support means, one based on electromagnetic force can be applied. However, the advantages and disadvantages of linear motor cars will continue to be the same, and weight increases and deterioration of energy efficiency cannot be avoided. Fuel may be loaded to drive a turbo fan or turbo jet.

In addition to the above-mentioned braking means, a spoiler or electromagnetic braking in the case of a nonear motor can be used as a braking means for the vehicle.

The vehicle was made of lightweight materials such as aircraft-grade duralumin.

There are only a few wings (one pair on the left and right is sufficient, and of course it is fine even if they are single wings).

Furthermore, if the ground effect is used, it is also possible to use the ceiling effect in a similar device. Ceiling effect refers to the characteristic that when a ceiling is placed above the wing, the smaller the distance between the ceiling and the wing, the more high lift is generated.If a means is provided to maintain the distance between the ceiling and the wing at a predetermined value, good.

The vehicle does not need to have only one flying body, but may have a plurality of flying bodies connected in a train shape. In this case, the propulsion device may be provided in only one flight main body and the others may be omitted, or the propulsion device may be attached to the other flight main bodies.

<Effects of the Invention> As described above, according to the present invention, it is possible to fly at a predetermined height position on a dedicated running track by levitating using the lift force based on the true theory of the wings and the lift force based on the ground effect. Furthermore, since the weight of the vehicle can be reduced, the energy for levitation of the vehicle can be obtained only by thrust, resulting in high energy efficiency.

In addition, by improving the conventional Shinkansen elevated road, it is possible to easily construct a running track, and there is no need for a large runway.
Since it runs on a dedicated track, it can be controlled by computer, and its non-contact driving reduces noise. It is also an effective means to limit the use of aircraft to intercontinental travel and use the vehicle according to the present invention as a means of land transportation.
