Embodiment Construction

[0020] Aircraft permanent maglev electromagnetic ejection platform: dig a trench of 8 x 8 meters along one side of the airport runway, the length is equal to the airport runway, the foundation is about two meters of reinforced concrete (depending on the soil quality), and the wall is 1 meter thick steel bar Concrete, install the upper and lower magnetic rails on both sides of the side wall, and repel the corresponding magnetic rails of the aircraft permanent magnetic levitation electromagnetic ejection platform to play a guiding role. according to figure 2 , The profile of the guide rail is to make the guide rail, the upper width is 3.5 meters, the lower width is 2 meters, and the height is 5 meters. The surface is level with the runway. The length is the same as that of the airstrip. Accurately install each magnetic track. The guide rail needs to be installed in the middle of the foundation, and the water ditch should be done well. Aircraft permanent maglev electromagnet...

Abstract

The invention relates to a permanent magnet suspension electromagnetic ejection platform for an airplane and belongs to the technical field of magnetic suspension. The permanent magnet suspension electromagnetic ejection platform for the airplane is mainly characterized in that two groups of powerful repellent rare earth permanent magnets 11 are used to produce suspension force, and the repulsion of four groups of electret combined magnets 5, 8 and19, a ranging probe 7 and an automatic system 2 are used to solve the problems on weight of an airplane and attenuation of magnetic force to match the balance of suspension force; the four groups of electret combined magnets are arranged among the side wall and two wings of the permanent magnet suspension electromagnetic ejection platform (thereafter platform for short) for the airplane, and the strong push force of each linear motor symmetrically acts on the two sides of a guide rail to solve the problems on guide, drive and stabilizing functions 6, 18,9, 10; the figure 2 is shown as follows: the above groups of magnets and the linear motors are symmetrically mounted on the side wall, the permanent magnet under the two wings of the platform on the guide rails and the basic magnetic rail repel each other to form 10 tons of suspension force per meter; the platform is designed generally to be 20 meters long; the total suspension force of the platform is up to 200 tons and can eject the airplane which is about 200 tons, so that more than 90% of the take-off oil consumption of the airplane can be saved.

Description

Technical field: [0001] This invention belongs to the field of magnetic levitation technology. The difference from the existing magnetic levitation technology is that the existing one is electromagnetic levitation, but this invention is permanent magnetic levitation. The existing ones are reverse attraction to generate levitation force, but this invention is positive repulsion to generate levitation. force. And all permanent magnets and permanent electric combined magnetic rails adopt mutual repulsion, which overcomes the strong attraction generated by the two poles attracting each other, saves more than 90% energy than the existing electromagnetic levitation technology, greatly reduces magnetic pollution, and reduces operating costs. Background technique: [0002] At present, military and civilian airports in various countries in the world are taxiing and taking off on the runway. This is very fuel-intensive and susceptible to weather conditions. The invention "aircraft p...
