Wu Guanghui
Let China's large aircraft fly into the blue sky as soon as possible
Academician of the Chinese Academy of Engineering, currently the chief scientist of China Commercial Aircraft Co., Ltd. , the chief designer of the C919 large passenger aircraft series of national major projects
Wu Guanghui is designed as a large passenger aircraft The leader of the division system always aims at the cutting-edge technology of world aviation, always grasps the development direction of the world's advanced civil aircraft, and proposes design concepts and guiding ideology. In order to better understand the pilot's idea and integrate it into the aircraft design, in order to become a bridge between pilots and designers, in 2008, at the age of 48, he took advantage of weekends and holidays to learn extremely difficult flying with young people. . In 2014, he obtained his first pilot's license; in 2016, at the age of 56, he obtained his commercial pilot aircraft license.
Han Kecen
Diligent and diligent in work, honest, loving, dedicated and dedicated
Member of the Standing Committee of COMAC Science and Technology Committee, second-level expert, chief designer of the basic C919 aircraft Feedback that the C919 aircraft often made a "humming" sound during the test flight. Han Kecen temporarily changed the itinerary to Xi'an and went to Dunhuang to board the plane for troubleshooting. Time was limited. On the way back to Xi'an from Dunhuang, Han Kecen was still researching the source of the "hum" sound, and finally found in an inadvertently recorded video that the slat seal vibrated regularly with the airflow, and the vibration was related to the "hum". The timing of the "hum" sound is highly coincident. This experience of troubleshooting was later dubbed "one-shot set tone".
Wu Xin
Xiu Wu's soaring career from my original intention to serve the country As the captain, Xin has completed or participated in most of the difficult subjects such as FTD, high temperature special projects, negative acceleration, etc., and has led the completion of a number of efficient air-ground coordination schemes. Among them, it is the first time that a large-scale civil fly-by-wire aircraft performs negative acceleration test flight in China. The requirements and possible risks of the test flight are to explore the "no man's land" by the test flight. He led the flight crew to capture test flight resources on the territory of the motherland, successfully expanded the aircraft envelope, and lit up the "test flight map". The aircraft that Wu Xin flew, both in terms of execution efficiency and flight intensity, broke many records and set more than ten firsts, which is of great significance for shortening the C919 certification cycle.
Qi Xuefeng
Tian XingjianThe gentleman is the general manager of the C919 project since he was the general manager of the C919 project, Qi Xuefeng has been the leader of the army and devoted himself to the extremely hard work for several years. The field test flight test and model development are in the midst of the challenge. Since 2022, in the final stage of the C919 large passenger aircraft project certification sprint, Qi Xuefeng organized more than 100 core backbones of the C919 project team to overcome the severe impact of the epidemic, and successively moved to Yanliang in Xi'an, Zhangjiang in Shanghai, Zizhu Park and Jiaxing in Zhejiang and other places Implementing centralized office during wartime, over 200 days in a row, day and night, open holidays, holding more than 200 regular meetings during the wartime centralized office at 8 o'clock every night, working until late at night every day, organizing to overcome nearly 20 major technical problems that affect the collection of evidence , compiled more than 6,000 compliance reports, closed more than 490 airworthiness clauses, completed all pre-certification tasks nearly half a month ahead of schedule, and made outstanding contributions to the domestic C919 large passenger aircraft obtaining the type certificate.
Zhao Keliang
Abandon the idea of fluke and must make it into steel
Thick points and seconds made a blockbuster
The deputy captain of the C919 large passenger aircraft field test team, the deputy chief designer of the C919 model
Zhao Keliang is a well-deserved key man for C919 flight test and evidence collection, C919 In total, hundreds of subjects have to be tested, and he is responsible for a quarter of the test subjects. The flight technology integration team led by Zhao Keliang is responsible for aerodynamic design, icing, flight load, flight performance, handling stability, cockpit design, interior decoration, flight test planning and flight test support, etc. 110 compliance terms and special conditions , undertakes 37 flight test outlines and more than 800 flight test missions. As a "post-60s", he has boarded the C919, which is in the stage of a high-risk stall test flight time and time again. Although the requirements are quite high and the experience is not "beautiful", his answer is concise but powerful. "I am responsible for my plane, and I am fully responsible for the plane. Only by boarding the plane in person will you have the most intuitive feeling. As designers, we need such valuable information to make good design products."
