[0052]This embodiment provides a turbine engine unit (not shown), which includes a turbine engine (not shown) and the turbine engine exhaust noise reduction structure 10 provided in the first embodiment. An exhaust port (not shown) is arranged on the turbine engine, and the exhaust port is connected with the air inlet 130, so that the exhaust gas discharged through the exhaust port can enter into the diffusion cavity 110 through the air inlet 130, and After sufficiently diffusing in the diffusion cavity 110 , it is guided to the gas outlet 140 through the guide channel 120 , and is led out through the gas outlet 140 . Wherein, the exhaust noise reduction structure 10 of the turbine engine can reduce the exhaust speed and reduce the noise of the turbine engine unit.

Abstract

The invention discloses a turbine engine exhaust and noise reduction structure and a turbine engine unit, and relates to the fields of turbine engines. The turbine engine exhaust and noise reduction structure is applied to the turbine engine. An exhaust port is formed in the turbine engine. The turbine engine exhaust and noise reduction structure comprises a housing and an isolation structure; the isolation structure and the housing jointly form a diffusion cavity and a guide channel communicating with the diffusion cavity; an air inlet and an air outlet are formed in the housing; the air inlet communicates with the diffusion cavity and is connected with the exhaust port; one end, far from the diffusion cavity, of the guide channel communicates with the air outlet; the area of the air inlet is less than that of the air outlet; and an included angle is formed between the guide direction of one section of the guide channel and the orientation of the air inlet. The turbine engine unit adopts the turbine engine exhaust and noise reduction structure. The turbine engine exhaust and noise reduction structure and the turbine engine unit can reduce the exhaust velocity and reduce regenerated noise.

Description

technical field [0001] The invention relates to the field of micro engine sets, in particular to a turbine engine exhaust noise reduction structure and a turbine engine set. Background technique [0002] As an important combat unit, individual soldiers are carrying more and more intelligent and informational equipment. Processing systems and life support systems, etc. At the same time, the personal portable generator set provides power supply guarantee for the equipment. The lightweight and silent technology of micro-generator sets is the most effective means to solve the power supply guarantee problems of individual soldiers and combat squads in the field without mains power, such as communication, combat, and portable equipment. Therefore, all military powers in the world are scrambling to develop miniature high-density generator sets to meet the needs of individual combat. Due to the high speed and high power density of the turbine generator set, it is the main directi...
