Research Field
To meet the extreme manufacturing needs of the aerospace and power engineering fields, work is carried out in the R&D of composite additive manufacturing, thermal management of high-end equipment, and intelligent and low-carbon manufacturing technologies. Research is also conducted on small- and medium-sized gas turbines, as well as on aviation conversion gas turbines.
Research directions:
■ Composite Additive Manufacturing
To meet national demands in aerospace and other key areas, integrated design of materials, structure, and functions with additive manufacturing is conducted. Multi-metal additive manufacturing equipment and processes researches are carried out; in-situ monitoring for additive manufacturing, and defect control research in refractory metal additive manufacturing are developed.
■ Thermal Management for High-End Equipment
Aimed at improving the performance of high-end equipment such as industrial machine tools, hypersonic vehicles, computing centers, and lasers, thermal management technology is explored, and investigations on designs and manufacturing of high-performance heat pipes, micro-nano-channel clusters, and microchannel cooling devices are conducted.
■ Intelligent and Low-Carbon Manufacturing
Focusing on aerospace and energy equipment fields, intelligent industrial software such as CAM/CAPP/CFD, adaptive processing, and intelligent inspection with independent intellectual property rights is developed. Also green and intelligent equipment like spraying devices are investigated.
■ Research and Development of Small- and Medium-Sized Gas Turbines
Research on performance parameters of small- and medium-sized gas turbines. Turbine design, control system design, whole-machine testing, and development of novel power systems.
■ Development of Aviation Modified Gas Turbines
Research on design and flow matching of 5–10 MW aviation modified gas turbines, key technologies for converting aero engines to land-based use, as well as integration, testing, and promotion of the whole aviation modified gas turbines and generator sets.
Team Building
The new technology laboratory consists of four research teams, including 52 employees, with 6 senior staff members, 6 deputy senior staff members, and 14 intermediate staff members. There are 4 postdoctoral fellows and 21 graduate students (among them, there are 7 international students and 9 joint-trained students).
Project and Major Achievement
In 2024, there were 51 projects under research, including 29 new projects.
In composite additive manufacturing, we've completed the development of a multi-metal additive manufacturing prototype, as well as the development of an aero-engine integrally bladed disk made via multi-metal additive manufacturing. We've achieved design and integrated manufacturing of core components like lattice-filled, highly efficient, compact heat pipes. Our hollow lattice refractory metal tungsten alloy leading edge, compared to traditional designs, has a weight reduction of over 42%, with a formed density of the tungsten alloy exceeding 99%, and we've realized crack-free printing of tungsten.
Regarding thermal management for high-end equipment, we've built a temperature-field measurement system for the entire machine with hardware and software intergrated, and set up a heat-error prediction model. Also, we took part in the 26th China Hi-Tech Fair and the Chinese Academy of Sciences-Guangdong Science and Technology Achievements Matchmaking Conference.
In intelligent and low-carbon manufacturing, we've completed one comprehensive monitoring platform for CNC machine tools, one tool-condition monitoring system, and one adaptive control system for the machining process. We've developed a production assembly process knowledge management system and a knowledge-delivery system. The knowledge-delivery system, based on machine learning models, meets the assessment criteria of a delay of no more than one second and an accuracy rate of no less than 80%. We've also developed specialized CAM software and CNC machining simulation software for integrally bladed disks. And we've led the formulation of the “Green Operation and Maintenance Standards for Computing Centers in the Field of Artificial Intelligence”.When it comes to small- and medium-sized gas turbines, we've assisted in manufacturing a 16 MW gas turbine. We've designed necessary test components, and carried out test preparation work.
In the field of aero-derived gas turbines, the HAT gas turbine has completed an 8 MW operation test and a machine test with 20% air humidification. Its overall design, combustion chamber development, and overall operation control have all been verified.
