The disclosure provides an aircraft and an engine of the aircraft, and relates to the field of aviation technology. The engine includes an outer casing, an inner casing, a first rotating shaft, a first fan, a second fan, a first combustion chamber and a second combustion chamber. An outer channel is formed between the inner casing and the outer casing, and the inner casing has an inner channel; the inner casing includes a first section and a second section axially distributed, and the first section is located in the second section near the outer air intake end. side. The first rotating shaft is rotatably arranged in the inner casing. The first fan includes an inner turbine part, a first connection part and an outer turbine part, the inner turbine part is connected to the first rotating shaft and located in the inner channel; the second connection part is connected to the inner turbine part around, and the outer turbine part is connected to the second connection part And located in the outer duct. The second fan is connected to the first rotating shaft, and the outer diameter of the second fan is larger than that of the first section. The first combustion chamber is arranged between the second fan and the outer turbine part. The second combustion chamber is provided between the second fan and the inner turbine part.
Description
technical field [0001] The present disclosure relates to the field of aviation technology, in particular, to an aircraft and an engine of the aircraft. Background technique [0002] At present, with the development of aviation technology, people have higher and higher requirements on the performance of the aircraft, wherein, as a core component of the aircraft, the performance of the engine is directly related to the performance of the aircraft. Among them, the turbofan engine is widely used. The existing turbofan engine generally includes an inner duct and an outer duct. The airflow from the external duct is mixed and ejected in the nozzle to provide thrust to the engine. At the same time, there is usually an afterburner between the outer duct and the nozzle, which further burns the airflow flowing out of the inner duct and the outer duct, thereby increasing the thrust of the engine. However, the afterburner increases the length of the engine, and the fuel consumption of ...
