Example

[0031] First embodiment

[0032] See figure 1 In this embodiment, a turbine engine exhaust noise reduction structure 10 is provided, which is applied to a turbine engine (not shown), where the exhaust velocity of the turbine engine is relatively large, and the exhaust noise caused by it is also particularly large. The turbine engine exhaust noise reduction structure 10 is connected with the turbine engine, which can greatly reduce the exhaust velocity of the turbine engine, and can greatly reduce the regeneration noise generated by the exhaust gas, and can meet the requirements of high flow velocity noise reduction of the turbine engine.

[0033] Wherein, the turbine engine is provided with an exhaust port (not shown), the turbine engine exhausts through the exhaust port, the turbine engine exhaust noise reduction structure 10 is used to connect to the exhaust port, and the turbine engine exhaust noise reduction structure 10 It is used to reduce the speed of the exhaust gas dischar...

Example

[0051] Second embodiment

[0052] This embodiment provides a turbine engine assembly (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 in the figure) is provided on the turbine engine, and the exhaust port is connected to the intake port 130 so that the exhaust gas discharged through the exhaust port can enter the diffusion cavity 110 through the intake port 130, and After being sufficiently diffused in the diffusion cavity 110, it is guided to the air outlet 140 through the guide channel 120, and is led out through the air outlet 140. Among them, the turbine engine exhaust noise reduction structure 10 can reduce the exhaust speed and noise of the turbine engine unit.

Abstract

The invention discloses a turbine engine exhaust noise reduction structure and a turbine engine unit, and relates to the field of turbine engines. The invention provides a turbine engine exhaust noise reduction structure, which is applied to the turbine engine. The turbine engine is provided with an exhaust port. The turbine engine exhaust noise reduction structure includes a casing and an isolation structure. The isolation structure and the casing together form a diffusion space. The housing is provided with an air inlet and an air outlet, the air inlet is connected with the diffusion cavity, the air inlet is used to connect with the exhaust port, and the guide channel is away from the diffusion cavity. One end communicates with the air outlet, the area of ​​the air inlet is smaller than the area of ​​the air outlet, and the guiding direction of one section of the guiding channel forms an included angle with the orientation direction of the air inlet. A turbine engine unit adopts the above turbine engine exhaust noise reduction structure. The turbine engine exhaust noise reduction structure and the turbine engine unit provided by the invention can reduce the exhaust velocity and reduce the regenerative 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...
