1In July, 1962, he was engaged in theoretical and experimental research on aerodynamics of steam turbine flow passage in Shanghai Turbine Boiler Research Institute of China No.1 Ministry of Machinery Industry, and served as the leader of long blade research group and deputy director of aerodynamics research office. He put forward a new theoretical method to calculate the fluid loss of cascade and a general theoretical formula to calculate the exciting force of steam turbine blades.
1964, Yao was appointed as the chief designer of the 200MW turbine set 1000mm twisted blade of Harbin Steam Turbine Works by the First Ministry of Machinery Industry.
In 1965, Yao created a new method for drawing long twisted blades and a computer-aided design method for long twisted blades.
1967 65438+February, worked in Sichuan Dongfang Steam Turbine Factory, and served as the director, deputy chief engineer and chief engineer of the product laboratory of the factory. He led more than 0/00 scientific and technical personnel of the branch company/KLOC to build a relatively complete set of steam turbine, gas turbine and compressor laboratories, and completed a lot of experimental research work. During this period, he was responsible for the research, design and manufacture of 300MW large steam turbine with twisted blades 1000mm, the first director in China. This steam turbine unit was designed and manufactured under the condition of factory's self-reliance. This turbine has been running safely for 10 years, and it has been awarded three times by the Ministry of Electric Power Industry for its good performance.
1983 12 was transferred to the Ministry of Machinery Industry, and has served as chief engineer, director of science and technology department and chief engineer of the Ministry of Machinery and Electronics Industry.
1993, successively served as deputy director of the Ministry of Machinery Industry, Science and Technology Committee of the State Bureau of Machinery Industry, and honorary president of China Academy of Agricultural Sciences. Organized scientific researchers to complete the "Eighth Five-Year Plan" scientific and technological research project of the State Science and Technology Commission-diesel engine waste heat utilization project, and won the "Eighth Five-Year Plan" scientific and technological research achievement award (single award) from two committees and one department (Planning Commission, Science and Technology Commission and Ministry of Finance).
65438+ 1994 was elected as the first batch of academicians of China Academy of Engineering in May, and was also elected as the director of the Department of Mechanical and Transportation Engineering and a member of the presidium of the Academy of Engineering.
During the period of 1996, he led hundreds of researchers and professors to complete the national natural science foundation's major project "Basic research on key technologies of giant hydro-generator set in the Three Gorges of the Yangtze River", which was concluded in May 1999 and was awarded as an excellent project.
1998 was hired by Shandong Provincial People's Government as the president of Shandong University of Technology (hereinafter referred to as Shandong Institute of Technology), a senior scientific and technological consultant of Shandong Province and a senior consultant of Jinan Municipal Government. On July 2 1, after in-depth discussion with Yao, Shandong Science and Technology Commission decided to set up Shandong Clean Energy Engineering Technology Research Center in Shandong University of Technology, and Yao personally took the lead in tackling key national problems such as "biomass rapid pyrolysis technology" and "proton exchange membrane fuel cell technology". On July 5, 1999, the research center was formally established with the approval of the provincial science and technology commission, and a grand unveiling ceremony was held in the school. It is the first clean energy research institution in China.
1In August 1999, he was transferred to University of Shanghai for Science and Technology as the director, professor and doctoral supervisor of the Institute of Power Engineering and Environmental Energy. Yao has worked in the front line for a long time and is a famous technical expert of steam turbine in China. Led scientific and technical personnel to develop 300MW high-power steam turbine and 6MW split-shaft gas turbine unit, won the second prize at provincial and ministerial level twice, and published more than 60 papers.
On September 8th, 2005, seven academicians of China Academy of Engineering, including Yao, and the heads of relevant departments of Zibo gathered together to make suggestions and suggestions for the 11th Five-Year Plan of Zibo's national economic and social development. It is pointed out that it is good for Zibo to strengthen the three dominant industries of chemical industry, medicine and new materials, but it should focus on new materials and run its own characteristics. Only by learning from others' strengths in the development and utilization of new materials, rather than being limited to a certain new material, can we create a "Silicon Valley" of new materials in China. In this way, if national enterprises need new materials, the first thing that comes to mind is Zibo.
On May 3rd, 2006, on behalf of Shandong University of Technology, Yao signed an agreement with the Provincial Economic and Trade Commission on cooperation in science and education to build a strong province. The school has implemented the action plan of building a strong province serving and manufacturing, strengthened the cooperation between schools and colleges, and promoted the integration of Industry-University-Research, which has built a good platform for accelerating the transformation of scientific and technological achievements into real productive forces.
On June 30, 2006, Yao was appointed honorary dean of the School of Mechanical and Power Engineering of Shanghai Jiaotong University. After the appointment ceremony, he gave an academic report entitled "New Methods of Product Design", which mainly introduced the basic content, development direction, application field and research direction of virtual manufacturing technology.
On June 29, 2007, the Ministry of Science and Technology set up an expert advisory committee on scientific research integrity, and Yao became a member.
On July 1 1, 2008, Yao died in Beijing on July 1 1, 2008 at the age of 76. The memorial service was held in Babaoshan, Beijing.
