The invention relates to a centrifugal multistage turbofan efficient aviation novel engine structure. The centrifugal multistage turbofan efficient aviation novel engine structure comprises a thrust device containing a centrifugal multistage fan main air inlet and outlet outer duct, an air spraying device containing a centrifugal multistage compressor high pressure inner duct and an inner duct airinlet. The centrifugal multistage turbofan efficient aviation novel engine structure is characterized in that under the effect of a rotor, centrifugal multistage fans rotate at a high speed to form an air pump, formed high pressure gas is outwards pushed through an exhaust opening of the outer duct, and turbofan engine main thrust is formed; centrifugal multistage compressors rotate at a high speed to form an air pump, the supercharge ratio is greatly increased, a turbine motor is pushed when high temperature and high pressure air burnt by a burning chamber is sprayed outwards, and the air issprayed out through an ai
