A Review on the Manufacturing Technology of High Property Blisk

整体叶盘是先进大推力航空发动机的一种新型结构部件,它的应用对于提高发动机性能、简化结构、降低重量、提高可靠性等具有重要的作用。主要介绍了航空发动机整体叶盘的先进制造加工技术,综述了采用精密锻造技术、精密铸造技术、线性摩擦焊接技术、数控铣削加工技术和电解加工技术制造整体叶盘的国内外研究现状与各项技术的优缺点,并展望了我国高性能整体叶盘先进制造技术的发展方向。

Blisk was a new integrated structure of blades and disk actually used in the aero-engine of high thrust-weight ratio, and the structure form was beneficial to reduce the number of parts and weigh which greatly improved the engine per-formance and reliability. The paper introduced advanced manufacturing technologies for the blisk, and reviewed the re-cently development and their merits and drawbacks of precision forging technology, precision casting technology, linear fric-tion welding technology, NC milling technology, and electrochemical machining technology used to manufacture the blisk, and finally analyzed the development tendencies of the blisk manufacturing technology in our countries.
