AeroDynamics develops new technology for aero-engine titanium alloy blade production

Recently, AeroDynamics announced that it has recently obtained the authorization of an invention patent titled "A method of diffusion connection of titanium alloy hollow blade", which marks a new breakthrough in the manufacturing technology of key components of aero-engine. This news triggered widespread attention in the industry, showing the continuous improvement of ADFD's technological innovation and R&D strength.
According to the data of Enterprise Search, the patent application number of the patent is CN202211201897.5, and the date of authorization is July 23, 2024. The patent abstract describes in detail the five key steps of the diffusion joining method, including clamping and fixing the titanium alloy hollow blade blank in a vacuum environment, and finally realizing the diffusion joining of the titanium alloy hollow blade through the process of three times of warming and the corresponding holding time. This method effectively solves the problem of blocking the diffusion of pressurized atoms in the joint due to the constant pressurization in the traditional diffusion joining process, thus affecting the performance of the joint, which is of great significance for improving the performance and reliability of the aero-engine.

It is worth noting that AeroDynamics has achieved remarkable results in patent authorization this year, with a total of 31 new patents authorized. Although this number has decreased (by 76.15%) compared to the same period last year, AeroDynamics' R&D and innovation activities remain active considering the complexity and approval cycle of patent applications. In addition, the financial data of the company's 2023 annual report shows that the company's investment in R&D amounted to 553 million yuan, which is a decrease of 22.1% year-on-year, but this level of investment still demonstrates the company's high regard for and continued investment in technology R&D.
AeroDynamics, as a leading enterprise in the field of China's aero-engine, has been committed to enhancing its independent innovation capability and promoting the independent control of aero-engine technology. The patent for the diffusion connection method of titanium alloy hollow blade not only highlights the company's profound accumulation of key manufacturing technologies, but also injects a new impetus for the company's future development.
Looking ahead, AeroDynamics will continue to increase investment in R&D, strengthen technological innovation and talent training, and continuously improve its core competitiveness. At the same time, the company will also actively pay attention to industry dynamics and market changes, grasp the development opportunities, and make greater contributions to promoting the development of China's aero-engine industry.
