Wang Wei, a special technician of aerospace, died of illness at the age of 48

On September 22, the Aerospace Sea Eagle (Zhenjiang) Special Materials Co., Ltd. issued a notice that Wang Wei, a special technician of China Aerospace Science and Industry Group, died in the early morning of the day at the age of 48.

Wang Wei has won a number of honors. He is a leader in Jiangsu Province manufacturing craftsman and a national skilled master studio. During his lifetime, he exceeded many difficulties in the field of aircraft assembly and made a great contribution to the delivery of the first large domestic aircraft.

Wang Wei's workmates before lifetime

Overcome multiple technical difficulties

Started the front line for two consecutive months

In the second half of 2015, Wang Wei received the assembly mission behind the fuselage after the C919 passenger plane. He said, "The complete independent C919 large aircraft is a new thing. Many technical issues during the assembly process are also the first time I touched it arrive."

There are hundreds of parts and tens of thousands of standard parts in the back of the fuselage of the C919 passenger aircraft. It is necessary to complete 15 -hole test projects, involving more than 1,800 composite material test films, and the number of holes reached more than 20,000. In order to ensure the smooth delivery of the back of the fuselage after the first machine, under the circumstances of heavy tasks, no foreign aids, and the difficulty coefficient, Wang Wei gave up holiday rest. , Solve various technical problems. In the end, the development and assembly work of the post -rear stage after the C919 was successfully completed, and it contributed a huge contribution to the delivery of the first large domestic aircraft.

Wang Wei studied hard before his lifetime, and he was improving. The technical difficulties of the aircraft assembly riveted were overcome by him one by one:

Successfully solved the problem of riveting and holes in composite materials; by improving technology and optimizing the inspection process, the component assembly cycle was shortened by more than 30%, and the research results were promoted and applied in the assembly of other composite materials components in C919 to obtain Chinese COMAC experts. Highly recognized; participated in the research and development of digital manufacturing technology based on digital detection, which reduced the manufacturing cost by 30%-40%, the product development cycle was shortened by 40%-60%, and the technology was applied to the first machine behind the first machine fuselage. Equipment of the segment; the hole -making experiments of the composite material parts are performed to meet the process compliance requirements of the composite composite stacking structure of the composite material, so that the sea eagle special company becomes the first composite material parts to complete C919 body structure supplier.

Since becoming a representative of the National People's Congress, he has proposed a number of suggestions such as "improving the introduction of skill talents and retaining talents", "improving the protection of grassroots courts", "strengthening the supervision of short video APPs" and "proposals to abolish relatives".

farewell!
