Chapter 42 41. Wu Daguan - the father of aero engine power

Wu Daguan (1916-2009), male, Han nationality, from Zhenjiang City, Jiangsu Province, a member of the Communist Party of China.During his lifetime, he was a member of the Standing Committee of the Science and Technology Committee of the former Ministry of Aviation Industry.Famous aero engine expert. Wu Daguan graduated from Southwest Associated University in 1942, and then went to the Lycoming Engine Factory and Pratt & Whitney in the United States for further studies. In March 1947, he rejected the high-paying employment of relevant units in the United States, and resolutely returned to serve the motherland. In November 1949, he served as the leader of the aviation preparatory group of the Ministry of Heavy Industry of New China, participated in the preparation of the new China's aviation industry, and was the founder and founder of my country's aero-engine business.His struggle is closely connected with many "firsts" in the new China's aero-engine industry: he established the first aero-engine design organization in New China, led the development of my country's first jet engine model, and created the first in my country's aviation history. An engine test base, presided over the establishment of the first set of effective rules and regulations for aero-engine development, established the first aerodynamic design and development team in New China, and presided over the compilation of my country's first general specification for aero-engine development, known as "Father of China's aero-engine".He was awarded the honorary title of "Old Expert with Outstanding Contributions" by the former Ministry of Aeronautics and Astronautics, and was posthumously awarded as a national outstanding Communist Party member after his death.

In the early days of the founding of the People's Republic of China, Chairman Mao repeatedly emphasized: "We must not only have a strong army, but also a strong air force and navy." To defend the "air supremacy" of the motherland's airspace, we must establish an independent aviation industry and cultivate a A self-designed aircraft and engine team.Among them, the development of the engine is more critical, because it is the "heart" of the aircraft and plays an extremely important role in the safety, reliability, and combat performance of the aircraft. In September 1956, Wu Daguan went to Shenyang Liming Engine Factory as the director of the first engine design room in New China.Five years later, he presided over the creation of my country's first engine design research institute in Shenyang, the Aero Engine Research Institute of the Sixth Research Institute of the Ministry of National Defense.

Everything is difficult at the beginning, how to design the engine?He thought hard and decided that the first jet engine would start from a trainer. In March 1957, the development of the Jet 1A engine began. Manpower transfer, information search, and equipment construction... There are many problems and complex problems. The most important thing is that the engine development must carry out parts and machine tests.In order to design and manufacture experimental equipment so that test technicians can learn electronic technology, Wu Daguan took out the six vacuum tube long and short wave radios he brought back from the United States for them to disassemble and practice.He led the trial production staff to make the tester by themselves, and solved the two most critical tests of the engine's flame tube and turbine blade cascade.After more than 200 days and nights of hard work, the engine was successfully developed that year. On July 26, 1958, the JJ-1 aircraft equipped with the Jet-1A engine was successfully tested.The newborn "Chinese Heart" began to beat! On August 5, Marshal Ye Jianying, then Vice Chairman of the Military Commission, and Commander Liu Yalou of the Air Force visited Shenyang to attend the celebration meeting of thousands of people. In September 1958, two JJ-1 planes equipped with Eruption 1A went to Beijing and made a wonderful flight show.One year later, Dongfeng 107, a high-altitude and high-speed fighter equipped with a Hongqi 2 engine, successfully drove off, presenting a generous gift to the 10th anniversary of the National Day!After 18 years of research and development, the turbojet 7A engine has been designed and finalized. Its successful development is a successful leap from imitation to improved modification of Chinese engines.The turbojet 7A engine, together with the J-8 aircraft, won the National Science and Technology Progress Special Award. It is not only equipped with a large number of Chinese Air Force, but also exported to foreign countries. It has become an important milestone in the history of my country's aeroengines!The turbofan 6 engine is an important model developed by Wu Daguan during his lifetime. In 1964, when the world's first afterburning turbofan engine was just beginning to be developed, he led researchers to track the advanced technology of this world's aero-engine.He made up his mind that if he wanted to do it, he would do the most advanced. In the later period of the "Cultural Revolution", Wu Daguan, who was "liberated", immediately put himself into the test work of the turbofan 6 engine before he had time to heal his body.The development of the turbofan 6 engine has provided sufficient talents and technical reserves for the development of my country's Kunlun and Taihang engines in the future, and has accumulated rich development experience.

In his later years, Wu Daguan still did not change his infatuation with aero-engines. In 1983, when the country was demonstrating the third-generation combat aircraft developed by my country, it focused on the issue of importing foreign engines or self-developed. At that time, opinions were very different, and many people strongly advocated the introduction of mature foreign engines.At this critical moment that determines the future and fate of the Taihang engine, Wu Daguan shouted loudly: "We must embark on a road of China's independent development of aero-engines. Otherwise, we will always be controlled by others, and fighter jets will never have Chinese cores!" Headed by Wu Daguan Nine experts jointly signed a letter to Comrade Deng Xiaoping, which aroused the great attention of the Party Central Committee, and the Taihang Engine project was approved.His far-sightedness determined the development direction for the development of new aero-engines. In 1993, an important test developed by Taihang Engine reached the standard at one time. After hearing the news in Beijing, he said excitedly: "This is the best news! This proves that we have this ability. Taihang Engine There is great hope!" After 18 years of honing, the Taihang engine has finally become a powerful tool.After hearing the news of the successful development of the "Taihang" engine, Wu Daguan was so excited that he burst into tears.

Over the past decades, under the leadership of Wu Daguan, my country has established an increasingly perfect research and development system and cultivated a team of excellent scientific research personnel; 6 The development of the engine and the patented production of the Spey engine have compiled the general specifications of the engine. Wu Daguan has written yesterday, won today, and established tomorrow in the history of Chinese aeroengines throughout his life.
