The front stator, the rotor and the back stator are arranged axially, the rotor is arranged between the two stators, the air inlet working end surface of the rotor and the air outlet working end surface of the front stator are mutually closely overlapped, the air inlet of the rotor and the air outlet of the front stator have the same number, shape and area, the air inlet closed zone of the rotor and the air outlet closed zone of the front stator have the same number, shape and area, when the rotor rotates, all the air inlets of the rotor and all the air outlets of the front stator can be mutually completely overlapped and communicated, the air outlet working end surface of the rotor and the air inlet working end surface of the back stator are mutually closely overlapped, the air outlet of the rotor and the air inlet of the back stator have the same number, shape and area, the air outlet closed zone of the rotor and the air inlet closed zone of the back stator have the same number, shape and area, when the rotor rotates, all the exhaust ports on the rotor and all the air inlets on the rear-stage stator can be simultaneously and completely superposed and communicated with each other, the directions of the space holes on the rotor and the stator are opposite, when the air inlet of the rotor and the air outlet of the front-stage stator are completely overlapped and communicated with each other, the air outlet of the rotor is sealed by the air inlet sealing area of the rear-stage stator, when the sealing ratio is more than 1, the middle position of the sealing area seals a space port, according to the mutual position arrangement structure of the space port and the closed zone on the rotor and the stator, the space port and the closed zone of the stator at the front stage and the stator at the rear stage are fixed in position, when the rotor rotates, the mutual positions of the space ports and the closed areas of the front stage stator and the rear stage stator are unchanged to form a closed compressor, according to the requirements of engines with different performances, the number of the closed compressors can be increased to form a multistage closed compressor, and the stators of the two closed compressors which are overlapped with each other can share one stator.

The working principle of the closed type gas compressor is as follows: when the rotor rotates, the mutual positions of the space port and the closed zone on the preceding stage stator and the following stage stator are unchanged, when the exhaust port of the preceding stage stator and the air inlet port of the rotor are communicated with each other to work, the gas in the space of the rotor forms a low-pressure zone at the air inlet port of the rotor under the action of centrifugal force, the gas at the air inlet port of the rotor is lower than the gas at the exhaust port of the preceding stage stator, the gas at the exhaust port of the preceding stage stator enters the space of the rotor, the rotor continues to rotate, when the exhaust port of the rotor and the air inlet port of the following stage stator are communicated with each other to work, because the air inlet port of the rotor is closed by the exhaust closed zone of the preceding stage stator at the moment or is partially closed, the exhaust port of the preceding stage stator is also closed by the gas inlet closed zone of the rotor at the same time or is partially closed, the influence of the gas at the exhaust port of the preceding stage stator on the gas inlet port of the rotor is greatly reduced, and the gas in the space of the rotor is acted by the centrifugal force, when the air inlet of the rotor and the air outlet of the front stator are mutually communicated to work again, the closed type air compressor finishes one working process, the larger the sealing ratio of the rotor and the stator of the closed type air compressor is, the longer the air outlet of the rotor and the air inlet of the rear stator are mutually communicated to work, the longer the time that the air inlet of the rotor is sealed by the air exhaust sealing area of the front stator is, the smaller the influence degree of the air pressure of the air outlet of the front stator on the air pressure of the air inlet of the rotor is, and the lower the air pressure formed by the air inlet of the rotor under the action of the centrifugal force of the rotor is, meanwhile, the higher the air pressure formed at the rotor exhaust port is, the larger the air pressure difference formed between the rotor exhaust port and the air inlet port is, the higher the working efficiency is, when the sealing ratio on the rotor and the stator is more than 3, in the process that the air exhaust port of the rotor and the air inlet port of the rear-stage stator are mutually connected to be completely disconnected, the air inlet port of the rotor is completely sealed by the exhaust sealing area of the front-stage stator, the air pressure at the air inlet port of the rotor is not influenced at all by the air pressure at the air exhaust port of the front-stage stator, the gas in the rotor space forms an extremely low air pressure area at the air inlet port of the rotor under the action of centrifugal force, and simultaneously forms an extremely high air pressure area at the air exhaust port of the rotor, and a great air pressure difference is formed between the air exhaust port and the air inlet port of the rotor, and according to the law of conservation of energy, the centrifugal force in the rotor space is completely converted into high air pressure energy at the position of the rotor exhaust port, and the high air pressure energy is completely pressed into the space of the rear-stage stator through the air exhaust port of the rotor, the closed type compressor has the highest working efficiency and is also the main reason that the closed type compressor has higher working efficiency compared with the traditional open type compressor, because the air pressure of the air inlet of each stage of rotor of the traditional open type compressor is always influenced by the air pressure of the air outlet of the stator at the front stage, and a larger air pressure difference cannot be formed between the air outlet and the air inlet of the rotor, the traditional open type compressor needs a plurality of stages of rotors to work, if two closed type compressors work together at the moment, a multi-stage closed type compressor is formed, and the working modes of the two closed type compressors are the same as that of a ship lock.

The beneficial effects of the closed compressor are as follows:

1. the production cost of an aircraft engine is greatly reduced, the same rotating speed is achieved, the centrifugal force in the rotor space of the closed type air compressor and the huge pressure difference formed between the air outlet and the air inlet of the rotor are incomparable with the rotor of the traditional open type air compressor, the larger the sealing ratio of the rotor and the stator is, the higher the working efficiency is, when the sealing ratio of the rotor and the stator is more than 3, the unit volume air displacement of the closed type air compressor is about 1/16 of the air displacement of the traditional open type air compressor, meanwhile, the kinetic energy consumption of 15/16 is reduced compared with the traditional open type air compressor, the kinetic energy of 15/16 can be reflected on the closed type air compressor in a high rotating speed mode, the centrifugal force generated in the rotor space is in a positive proportion relation with the rotating speed of the rotor, and therefore, the air compression ratio of the primary closed type air compressor with the same power and the same volume is more than 10 times that of the primary rotor of the traditional open type air compressor, according to the requirements of engines with different performances, the closed compressors with different closing ratios are selected, the compressors of all turbine engines can be controlled within 5 levels, and the production cost of the engines is greatly reduced.

2. The multistage closed gas compressor is an optimal mechanical structure of a continuous high-energy weapon which takes gas and liquid as working media and has no time limit.
