03-26-2025 Author: KJ technology
The application of vacuum brazing furnace in the aerospace field is very extensive and important, mainly reflected in the following aspects:
1. Manufacturing key components
Aircraft engine components: Vacuum brazing furnaces are used to manufacture various key components of aircraft engines, such as turbine blades, compressor blades, combustion chamber components, honeycomb sealing structures, stainless steel heat exchangers, fuel manifolds, etc. These components need to work in extreme environments such as high temperature, high pressure, and high-speed airflow erosion, thus requiring extremely high welding quality and reliability. The vacuum brazing furnace can provide a non oxidizing and pollution-free welding environment, ensuring the strength and sealing of the welded joints.
Spacecraft structural components: In the manufacturing of spacecraft, vacuum brazing furnaces are also used to connect various structural components, such as flow windows. These structural components need to withstand extreme space environments, including high vacuum, strong radiation, and drastic temperature changes. The vacuum brazing furnace can ensure the stability and reliability of these structural components in extreme environments.
2. Meet high-performance requirements
High thrust to weight ratio: In order to meet the design requirements of high thrust to weight ratio for aircraft engines, new materials and structures are widely used. The vacuum brazing furnace can connect these new materials and structures, achieving high-performance aircraft engine manufacturing.
High reliability: The aerospace industry has extremely high requirements for the reliability of components. The vacuum brazing furnace ensures the quality and reliability of welded joints by providing a non oxidizing and non polluting welding environment, thereby meeting the high reliability requirements for components in the aerospace industry.
3. Application Cases
Foreign applications: For example, the JT9D engine honeycomb sealing ring and fuel manifold from Pratt&Whitney in the United States, as well as the engine casing from GE, are all manufactured using vacuum brazing technology. These components play a critical role in aircraft engines, and their welding quality and reliability directly affect the overall performance of the engine.
Domestic application: In China, Shenyang Liming Engine Company and Chengdu Engine Company have also adopted vacuum brazing technology to manufacture key components of aviation engines and successfully applied it to naval aircraft. These application cases fully demonstrate the importance and broad application prospects of vacuum brazing furnaces in the aerospace field.
