On July 19th, the Technical and Acceptance Meeting of the Aerospace Engine Turbine Blade Complex Shaped Hole Processing System was undertaken by the Laser and Intelligent Energy Field Manufacturing Engineering Team of the Advanced Manufacturing Institute of the Institute of Materials Technology and Engineering of the Chinese Academy of Sciences. Held at Ningbo Materials. Experts from the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, Shanghai Institute of Ceramics of the Chinese Academy of Sciences and Ningbo Haitian Seiko and more than 10 researchers participated in the on-site technical test.
The expert group listened to the project work report of the project leader Zhang Wenwu, reviewed the technical test outline on site, and tested the technical acceptance indicators one by one according to the test outline, and carried out five-axis linkage coordinate conversion, autofocus and compensation, and normal automatic detection. Depth control, multi-station shaped hole CAD drive intelligent processing and other functional demonstrations, and on-site drilling of flat parts and blade specimens, fully inspect the equipment's athletic ability, process capability and intelligent level of the kernel control system. According to the index requirements and measured results in the implementation plan, the expert group believes that the technical indicators of the “Aerospace Engine Turbine Blade Complex Shaped Hole Laser Processing System†have reached or exceeded the implementation plan, and successfully completed the development task, which is of great significance. Pass the technical acceptance.
Aeroengines are of great significance to national security and national economy. One of the performance indicators of aero-engines is the pre-turbine operating temperature. The improvement depends on the overall progress of high-temperature materials, thermal barrier coatings and film cooling technology, among which advanced film cooling technology The contribution of temperature increase is about 2/3. In the mid-1980s, the United States took the lead in using complex shaped pore film cooling technology, and the equivalent cooling efficiency of hot-end components such as turbine blades increased from 0.3 to over 0.5, and continues to progress. In China, due to the vacancy of the autonomous processing machine and the backwardness of the processing technology, the long-term failure to break through the complex shaped hole processing technology, the advanced cooling structure design can not be verified, the blade cooling efficiency has so far been different from the Western countries. The lag in cooling technology can indirectly lead to backward engine reliability and overall performance. Therefore, China urgently needs to break through the independent industrial machine tool and related process technology of complex shaped hole processing.
The shape of the aero-engine blade is twisted and the cavity is complex. It is necessary to use laser to machine high-precision and complex shaped holes on the blade. There are five-axis coordinate linkage conversion, autofocus and compensation, normal automatic detection and inclination control, CAD-driven multi-station automation. Many technical difficulties such as processing.
In response to the above challenges, the laser and intelligent energy field manufacturing engineering team has been working on the “simulation-design-equipment-process†innovation chain of complex shaped hole technology in the country after more than six years of continuous research, and has been supported by the Chinese Academy of Sciences equipment project. The company has developed a "complex shaped hole machining system for aero-engine turbine blades" and a complete set of processing technology. After the expert group's appraisal, the relevant technical indicators have reached or exceeded the implementation plan. The project has been greatly assisted by Ningbo Daai Laser Technology Co., Ltd., relying on the company, this technology has entered the stage of industrialization.
"Aerospace engine turbine blade complex shaped hole laser processing system" provides domestic mother machine and complete set of process methods for complex and special low-damage processing of aero-engine and gas turbine turbine blades, combustion chambers, flame tubes and other hot end parts, and can be extended to application. Micro-machining of three-dimensional curved surfaces enables precise three-dimensional processing of many difficult-to-machine materials such as diamond, quartz, ceramics, metals, composite materials, and resins. The breakthrough of this complete set of technologies is of great significance to promote the technological advancement of China's aero-engine and gas turbine hot end components and the breakthrough of micro-machining capabilities.
