Abstract

The invention discloses a turbine turbofan engine and a spacecraft. The turbine turbofan engine comprises an inner supporting structure arranged at the periphery of a main shaft and an outer supporting structure arranged at the periphery of the inner supporting structure, wherein an outer bypass airflow channel is formed between the inner supporting structure and the outer supporting structure; a combustion chamber is arranged in the outer supporting structure positioned outside the outer bypass airflow channel; an inner bypass airflow channel enables air to flow from an air inlet of the inner supporting structure and communicates to the inside of the combustion chamber along a radially-penetrating outer bypass airflow channel. The whole structure of the turbine turbofan engine is simple, large bypass ratio can be realized at a temperature before a low turbine, the propulsive force of the engine is increased, and the oil consumption rate is reduced.

Description

technical field [0001] The present invention relates to the technical field of aero-engine structures, and in particular, to a turbo-turbofan engine. Furthermore, the present invention also relates to a spacecraft comprising the above turbo-turbofan engine. Background technique [0002] The fan, high-pressure compressor, combustion chamber, high-pressure turbine and low-pressure turbine of a conventional turbofan engine are on the same axis. The schematic diagram is as follows image 3 shown. The high-speed rotating fan compresses the air to a certain pressure, and the air is divided into two parts through the diverting device, one part of the air enters the outer duct, and the other part enters the inner duct. Compressed air entering the inner canal is compressed to a higher pressure by a high-pressure compressor rotating at a higher speed. After the high-pressure air enters the combustion chamber, it is quickly mixed with the fuel, and after being ignited, a high-tempera...
