Description

Rail vehicle with wing wing vehicle with wing

Technical field

The present invention is a completely new type of vehicle that has both the speed and characteristics of the aircraft and is flying on the track like a train.

Background technique

In early 2008, severe snow and ice disasters occurred in 21 districts and cities in Hunan, Guizhou, Jiangxi, Jiangsu, Anhui and other provinces in southern China, causing more than 437,000 transmission towers to be destroyed, and more than 369,000 transmission lines damaged. The road transport was completely interrupted. Only 20,000 vehicles on the Beijing-Zhuhai Expressway were blocked and could not be operated. The shortest period was 3 days and the longest was 7 days. More than 20 airports were closed and more than 3,700 flights were cancelled. More than 1.9 million people who are returning home for the Spring Festival are blocked, and all traffic tools are unable to function, and even drinking water is difficult. Under this circumstance, the state has to take extraordinary measures to mobilize about 900,000 troops, more than 2.25 million militiamen, and mobilize thousands of local workers and people to participate in disaster relief and relief. The direct economic losses amount to more than 150 billion yuan, and the human and material resources invested are more It is difficult to count.

Will such a major disaster happen in the future? This is unpredictable. The key is to find countermeasures and methods to deal with such disasters. With good countermeasures and reliable methods, even greater disasters can be handled with ease. It is not difficult to see from the above disasters that the key problem that needs to be solved urgently is: How to make the transmission line not afraid of ice and snow, how to make the vehicle unblocked in ice and snow.

Summary of the invention

According to the shortcomings of the existing transmission lines exposed in the air, the ice is inevitable, the electric locomotive has no difficulty in walking, the car is bound to slip on the ice and snow, and the aircraft cannot take off on ice and snow. And the drawbacks of landing, in addition, air crash accidents have occurred in recent years. It reminds me of: It is necessary to create a brand-new means of transportation to make it run on the track, thus avoiding the problem of slipping, and placing the track in the air, hiding the transmission line under the track, so that it is not subject to any weather. Affected, if it is used as an imaging aircraft to fly on the track, it can replace the aircraft and does not need the airport, but become the fastest, safe and reliable all-weather vehicle on the land.

With such a vehicle, it is possible to replace the maglev train, because the principle of magnetic levitation is: It is necessary to lay a coil like a motor stator on two rails to generate a magnetic force, how long the track is, and how long the coil has to be laid. It is estimated that the cost is very high, and the equivalent of the motor rotor is installed on the locomotive. After the power is turned on, the powerful magnetic force generated by the two coils is used to suspend the locomotive and push the train forward, so the power consumption is also huge. In order to verify my estimation and experience the superiority of magnetic levitation, in 2008 I made a special trip to Shanghai to visit and take the maglev train. From the experience, I saw that its superiority is obvious. When the top speed is 431 kilometers, the car body is still It is as smooth as sitting in an airplane. It is also feasible to increase the speed to more than 500 kilometers per hour. (The information shows that the manned operation has reached 517 km/h), and the sound heard is similar to that of a plane. However, the cost is indeed very high. The investment of 30 kilometers is 10 billion yuan, the ticket for one-way ticket is 50 yuan, and the ticket for two-way ticket is 80 yuan. It is still a loss. It needs to subsidize 100 million yuan per year to maintain operations. It fully proved my estimation, so the maglev trains in Germany and Japan stopped operating, but Shanghai continued to operate. It can be seen that the development of such vehicles is subject to investment and operating costs.

Why can't high-speed railways, which are currently heavily invested and built in China, reach speeds like maglev trains? This is also determined by the structural characteristics of the wheel-rail traffic. Some people have done precision calculations. The maximum speed of wheel-rail traffic can only reach 350 kilometers. Beyond this speed, the adhesion between the steel wheel and the rail will become very high. Small, the steel wheel will slip on the rail and lose its progress. Power, practice has proved the correctness of its theory.

It can not be seen from the above analysis that the use of the wing instead of the magnetic levitation is the most economical method, not only the rail cost is greatly saved, but also the operating cost is greatly saved, even if the reciprocating orbit is separately constructed (the speed of the reciprocating track cannot be too close, Otherwise it is not safe.) The investment is also much less than the magnetic levitation track, and perhaps more than the existing high-speed railway track. Because the speed of this speed is faster, the track load is smaller. When the lift = gravity, the track load = 0. When the lift > gravity, the track will be slightly upwardly pulled. This force is very small, no It will have a bad effect, but it is still necessary to adjust the lift to make it as balanced as possible. At this point, the track only plays a guiding role (this is its greatest superiority, no other vehicle on the land can be comparable), unlike the present There are high-speed railways that are subject to dynamic loads and are required to be high.

However, at this time, it should be known that the speed of the wing is the determining factor. The speed of the wing is not enough. The speed of the existing general aircraft is about 300 km/h. Therefore, the wheel-rail type is impossible. Only a jet engine can accelerate it. At present, all jet engines are powered by aviation kerosene, which is polluting, but studies have shown that it is feasible to use electric energy as power. The use of electric energy to compress air and the use of jet air to accelerate the locomotive. This is the electric jet engine, which solves the problem of pollution well. Probably there is no such machine in the world. I believe the Chinese can definitely Created, and its speed can reach more than 500 kilometers per hour.

With this kind of engine, I believe that the Chinese can also create another miracle that allows the speeding train (train) to travel on a sloped track like a car, even over a certain slope of the mountain. This is currently impossible for high-speed railways. As a result, with this feature, the construction of the track can be greatly saved.

Because it has to run in the air 10 meters above the ground, it is not afraid of snow and ice disasters, Not afraid of floods, as long as the track is not flooded, it can operate. It is like an airplane and an airport. It is not afraid of falling from the air like a plane, and it will not crash like a car. It has no contradiction with ground vehicles and pedestrians. ). So it is the fastest and safest all-weather vehicle that is safe from any weather.

This kind of transportation also has a great advantage. It does not need to occupy a large amount of cultivated land, and it can be cultivated under the track. In this way, it has a major feature and advantage, that is, its construction cost is lower than the cost of the existing high-speed railway, and its fare is cheaper than the fare of the existing high-speed railway. Adding its speed, safety, and freedom from any weather, it must attract a large number of roads, railroads and air passengers, and allow them to travel quickly, safely and comfortably.

With this type of transportation, it is not afraid of the serious snow and ice disaster as in the beginning of 2008, and it can be handled calmly. The annual peak of the Spring Festival is not a problem. With this kind of transportation, the distance between people is relatively reduced. It takes only 3 hours for people from Beijing to Shanghai to meet. It takes only 5 to 6 hours for Beijing to Guangzhou, and 7 to 8 hours for Beijing to Urumqi. Arrivals. Therefore, it can be said that it is the most important means of transportation that is bound to develop at a high speed in the 21st century. It is not only an indispensable means of transportation between big cities, but also an important means of transportation in the world. When China is built into five vertical and five horizontal The rapid transportation network, which connects the neighboring countries and realizes the Eurasian Continental Bridge, is the era of China's take-off, and Mao Zedong said: "China should make a greater contribution to mankind." By then, this system will not only ensure the free flow of Chinese people in a fast and safe manner, but also ensure the free and free flow of people around the world and reduce the occurrence of air tragedies. It can also create jobs for thousands of people and increase their income. The country can also accumulate tens of billions of wealth to create conditions for the complete elimination of poverty and the common prosperity.

In addition, as I estimate, in the near future, China will create low temperatures for the transmission of electrical energy. Or high-temperature superconducting cable. When constructing the track of the flying car, if you can design the space for the cable in the future, you can avoid the repeated construction and large investment in the future. Now you can create a future investment with only a small investment. Conditions, according to my design, only need to install a cable installation room under the track, you can put 12 to 16 cables (superconducting cable and fiber optic communication cable), which not only saves a lot of investment for the country, but also for transportation companies. Bringing considerable profits, according to my estimation, the country's five vertical and five horizontal fast, net, can save hundreds of billions of dollars in investment in power construction, while bringing tens of billions or even billions of yuan in revenue for transportation companies. Not only that, but it has also created extremely safe and reliable conditions for power companies and communications companies, and even large snow disasters and man-made damage can not be hurt. Moreover, it can solve the unsafe situation in which many large city towers are lined up and the wires are densely covered. Such planning and construction are in line with the scientific development concept and forward thinking.

DRAWINGS

Based on more than one year of research, a preliminary design scheme is proposed, the specific structure of which is shown in Figure 1.

1 ― ― Track 9 1 — Track pier

2 one first car 10 one limit high wheel

3―One motor and transmission mechanism together 11—one drive wheel

4—one wing 12—one track beam

5―One auxiliary jet engine 13―One spare superconducting cable installation room

6 - one medium car 14 one aileron

7 one tail car 15 one wing

8 - an electric main jet engine detailed description

The implementation of this program can be divided into the following steps:

First step model experiment

Since this scheme is an unprecedented idea, it is impossible to achieve success in one step. Therefore, the first step must be to prove the feasibility of the scheme through model test. To this end, firstly, the simulation model of the first car, the middle car and the tail car will be made. Then, the electric jet engine model, as long as the electric jet engine can push the model forward and make the cabin suspend, is the test success, which proves that the scheme is feasible.

The second step is to manufacture a prototype car for no-load experiment.

The prototype car can be designed and manufactured according to the actual operation needs in the future, or it can be manufactured in a reduced proportion. After obtaining experience through experiments, the prototype product is designed.

The purpose of this kind of experiment is to find various problems through experiments, and then solve them step by step in various ways to make them succeed.

According to my assumption, the driving motor and the transmission mechanism are used to drive the driving wheel to run the train and accelerate it smoothly. When the speed is close to 300 km, the main jet engine is started to accelerate the train to 500 km/h or more. The generated lift slowly suspends the carriage, and the height limiter limits the levitation height to a certain range so that the wheels are not off track. The automatic control device can also automatically control the lift of the wing and make the carriage The balance is automatically reached, and the entire train is flying in orbit along the suspension of the wing. When the train is about to enter the station, as long as the jet engine is turned off, the inertia and the wheels can be slowly decelerated, so that the passengers will not feel uncomfortable regardless of starting and stopping.

In the event of a failure of the main engine, the automatic control will automatically start all auxiliary engines. The train will continue to run smoothly without stopping the train, that is, some auxiliary engines will also fail, and the trains will also maintain high speed, because each auxiliary engine, in addition to ensuring the power of the vehicle, An extra energy reserve is available, and the total automatic console is automatically controlled.

In addition, once the train encounters a strong typhoon, hurricane or tornado, the wing of the train can be automatically folded or contracted. At this time, the wheel can be decelerated to avoid accidents and ensure the safety of driving. In addition, when a certain car fails and needs to be repaired, each station has an access passage. After the train arrives at the station, it can be taken out of the main road, moved to the auxiliary road, and replaced with a new car. After the train arrives at the terminal, the train can also be driven into the ramp for overall repair and maintenance. The number of trains in each group can be arranged according to actual needs. It is expected to be at least 4 knots and up to 12 knots, so that no-flight flight can be avoided.

I can think of ways to solve the above problems that may arise and encounter, and carry out experiments. After the success, this kind of experiment is completed.

Step 3 Construction of standard trains and standard tracks for official operation

When all the problems that may be encountered and thought are tested and solved, standardized design can be based on practical experience.

However, it should be thought that the no-load experiment is still very different from the actual operation. Therefore, the initial stage should also be regarded as the experimental stage. It is called “trial operation” as usual, and it is gradually increased from a few passenger experiments. Fully loaded with passengers, you can officially operate without any problems and everything is normal.
