The invention discloses an aircraft engine exhaust pipe and an aircraft with the aircraft engine exhaust pipe, and relates to the technical field of aircraft engines. The aircraft engine exhaust pipe comprises an inner pipe and an outer pipe, wherein the inner pipe contains an inner pipe transition section and an inner pipe extension section, one end of the inner pipe transition section is connected with an engine exhaust nozzle, the other end of the inner pipe transition section is connected with the inner pipe extension section, and an included angle is formed between the axis of the inner pipe extension section and the axis of the engine exhaust nozzle; the inner pipe is sleeved with the outer pipe, and an annular cavity is formed between the inner pipe and the outer pipe along the axis direction of the inner pipe. The aircraft comprises the aircraft engine exhaust pipe. The aircraft engine exhaust pipe and the aircraft have the advantages that the included angle which deflects downwards is formed between the axis of the exhaust pipe and the axis of the engine exhaust nozzle, tail jet flow is guided to the direction far away from the lower surface of a wing, and damage caused by high-temperature and high-speed fuel gas to an aircraft airframe is effectively avoided; meanwhile, engine nacelle temperature and exhaust pipe wall temperature are cooled sufficiently, the structure is simple, and installation is convenient and fast.
Description
technical field [0001] The invention relates to the technical field of aircraft engines, in particular to an aircraft engine exhaust pipe and an aircraft with the same. Background technique [0002] The turbine engine and the nacelle are hung in front of the aircraft wing through the engine frame. The high-temperature and high-speed gas generated by the combustion of the engine fuel is directly discharged from the airframe through the tail nozzle. Aircraft Airframe Hazards. At the same time, it will also cause the temperature of the accessories installed on the outer wall of the engine casing and the nacelle to be too high, which will affect the performance and service life. Contents of the invention [0003] The purpose of the present invention is to provide an aircraft engine exhaust pipe and an aircraft with the same. The engine exhaust pipe is used to discharge the high-temperature and high-speed gas generated after the engine fuel is burned, and effectively avoid the...
