Description
Technical Field

The common train is powered by electric power or a steam engine and moves forward through the rotation of wheels, so that the speed is low and the efficiency is low; the wheel rail high-speed rail is powered by electric power, and still moves forward through the rapid rotation of wheels, so that the speed is high, the current input into practice reaches 350km/h, and the speed space is further improved due to the restriction of the rotation speed of the wheels and the adverse factors of contact friction with the rail; the magnetic suspension high-speed rail realizes suspension and magnetic drive by providing a magnetic field through electric power, has high speed, is up to 350km/h which is put into practical use at present, has higher construction cost than the wheel track high-speed rail, also has air resistance, and has great cost for further improving the speed.
In the current research and development of the vacuum tunnel magnetic suspension super-high iron, the reduction of air resistance through the vacuum tunnel and magnetic suspension is assumed, the speed can reach more than 350km/h through magnetic driving, but the technical difficulty and cost factors of constructing the vacuum tunnel and high-temperature superconduction lead to the current research and development to be still in an initial stage and far away from practical application.
The principle of the air suspension train is that compressed air is sprayed onto a track by using an aeroengine with high power, so that an air cushion with the thickness of a few millimeters is formed between the bottom of the train and the track, and the whole train is supported and suspended on the track surface. The train is pushed forward by a propeller-type engine arranged at the back. Such trains are commonly referred to as "aerotrain". It is also called an "air train" because it appears to be held up by an air cushion. France is the country in the world where air trains were first built. In the 60 th century of the 20 th century, two air-suspended railways were built in paris and the suburban Orleans, one 18 km long and the other 6.7 km long, and a number of running tests were carried out. The test speed of the train is 200 to 422 km per hour. An air cushion vehicle used in the suburb of Orleans in 1969 is 26 m long, 3.2 m wide, 4.35 m high and 20 tons in weight and can take 3 persons. In 1955, two LWT-12 air trains were manufactured by Yi Andi, purchased by a railroad company such as the united Pacific, but failed to prevail. However, there is no report on how to design an air suspension train and a corresponding track so that the air suspension effect of the train is better, and related technical literature in the prior art.
Because the current most advanced vacuum tunnel magnetic suspension super-high iron relates to the technical difficulties, cost, potential safety hazard and magnetic field environmental protection problems of the realization of the super-conduction and vacuum tunnels, a novel gas suspension high-speed rail transportation device which can operate under normal ground atmospheric conditions, does not need a vacuum tunnel, does not need magnetic suspension, has low construction and operation and maintenance costs, is safe and reliable to operate, is easy to realize in technology, is efficient, energy-saving and environment-friendly and has the speed exceeding 350km/h is urgently desired.
