On July 26, 2022, the State Intellectual Property Office of China (SIPO) sent the good news that our director and chief scientist Prof. Xue Wei's "A method and device for laser impact strengthening of the bottom plane of the tongue and groove of aircraft blades" (Patent No. ZL201310384555.6) won the gold medal, realizing the landmark breakthrough of our institute in supporting the construction of national strategic scientific and technological It is a landmark breakthrough of our institute in supporting the construction of national strategic science and technology force and promoting the construction of new development pattern.
The patent is jointly developed by Prof. Xue Wei's team and the teams of Jiangsu University and Southeast University, which independently innovated the design of using the optical path transformation system to change the circular spot of the laser beam into a high power density bar-shaped spot, and at the same time, setting the inflow injection device and water pumping device at the two ends of the bottom of the tenon slot to achieve a uniform and stable water confinement layer to strengthen the bottom plane of the tenon slot by laser impact, solving the This solves the common technical problem of "plasma shielding" effect and uneven and unstable water confinement layer in the industry. At present, the patent technology has been successfully applied in China Aviation Development Shenyang Liming Aero Engine Co., Ltd. and Shenyang Aircraft Industry (Group) Co., Ltd. to lead the technological progress of China's high-end equipment core components laser strengthening manufacturing industry, to meet the needs of major national projects and significantly enhance international competitiveness. At the same time, it also provides strong support for the city's provincial technology innovation center and other innovation highland construction.
In recent years, our institute has been deeply implementing the national innovation-driven development strategy and the strategic deployment of a strong intellectual property rights, holding fast to the main line of high-quality development, highlighting the value-oriented and transformation-application-oriented, promoting the transformation of intellectual property rights from pursuing quantity to improving quality and promoting transformation, unswervingly implementing the innovation-driven strategy, continuously increasing the investment in science and technology, strengthening the key core technology research and development, continuously leading laser technology and promoting industry The China Patent Award is a prize awarded by the State Intellectual Property Office.
The China Patent Award is jointly granted by the State Intellectual Property Office and the World Intellectual Property Organization, and is held annually. It is the highest award in the field of intellectual property in China, and is the only governmental award in China that rewards inventions and creations granted with patent rights.
