The party flag fluttered at the grassroots level 丨 China Airlines: Insert the party flag on the main battlefield of scientific research and production

Aviation engine is the "heart" of the aircraft and one of the most complicated and precise industrial products. In order to take the road of independent development of the product, from 2016 to 2021, China Aviation Engine Group Co., Ltd. established more than 2100 "casting hearts" new Long March party members' assault team to overcome the main battlefield of scientific research and production.

In China Hangfa Hunan Institute of Power Machinery, the leader of the party members, Wang Xu, led the team members to be conducting the first renovation test of the AES100 civil turboshaft engine for the first time. Just 2 months ago, this engine had just passed the 3000 -hour operation test.

Wang Xu, Secretary of the General Research Department of China Hangfa Hunan Institute of Power Machinery: 3,000 hours, this is already a highest level in our country.

As the "heart" of the aircraft, the aviation engine directly affects the performance and reliability of the aircraft, and is an important manifestation of national science and technology, industry and national defense strength. In 2016, the AES100 engine development project was established. The goal was to use eight and a half years to produce a civilian turbhaft engine that was completely independent and independent in my country.

Wang Xu, Secretary of the General Research Department of Hunan Hunan Hunan Institute of Power Machinery: The technical indicators required are very high, the request to reach the international advanced level, and the development is quite difficult. Many people think that this is almost an impossible task.

In March 2017, China Hangfa Hunan Hunan Institute of Power Machinery regulated 28 technical backbones to form a "cast heart" new Long March party member assault team to launch an impact on this seemingly impossible task.

Wang Xu, secretary of the overall research department of Hunan Hunan Hunan Institute of Power Machinery: The party member assault team has to run with time. Since the country has this demand, we must complete this task as required.

What makes people unexpected is that during the program demonstration stage, the party members' assault team encountered heavy difficulties. In order to reduce the bearing temperature, the AES100 engine adopts a ring oil supply technology for small and medium -sized engines for the first time. At the beginning, it was not ideal for repeated test effects.

Wang Xu, Secretary of the General Research Department of China Hangfa Hunan Institute of Power Machinery Research: In a spatial range of a fist, we need to arrange bearing, lubrication, pipelines, sealing, and support more than a dozen components. This requirement is very high. The entire commando owner is engaged in brainstorming together, and we are all in a hurry.

The final period of the plan review is approaching day by day. In order to overcome the problems, each of the members of the party members' assault teams are like they are on the clockwork, collaborating, combined, and finally solved this technical problem in a timely manner.

Wang Xu, secretary of the overall research department of Hunan Hunan Hunan Institute of Power Machinery: People of different positions include design, trial production, and testing. Everyone is like a gear. As soon as the drawings push over, and then try to make the people over there, whether it is at night, they start working overtime.

The combustion room is the core component of the aviation engine. The highest temperature of the center exceeds 2000 ° C. This requires the designer to accurately control each detail to ensure that the engine can work normally in high temperature and high pressure environments.

Yang Yang, member of the party member assault team of Hunan Hunan Hunan Power Machinery Research Institute: Even if the relevant size deviates from 0.01 mm, it may cause severe changes in the temperature field. If the temperature field is unstable, it is likely to damage the engine.

During that time, the team members of the party members ate and lived in the office almost every day. Through the simulation test, they were a little refined towards the most ideal design solution.

Deng Wei, a member of the Party Member Commissioner of Hunan Hunan Hunan Hunan Power Machinery Research Institute: Our party members' assault team opened the 5+2 and white and black models. Many colleagues who lived far away brought marching beds and washing supplies to the office.

Under the cooperation of all members of the party member commando, the comprehensive performance indicators of the engine burning room finally reached the international leading level.

On July 27, 2021, the first flight of the AES100 engine dual -hair installation helicopter was successful, which marked a solid step in the independent development of my country's civilian turboshaft engine.

A party member is a banner. On the road of "casting the heart", the bright red party flag led the direction of the forward. A vibrant party member commando team guarded the cause of my country's aviation engine to continue to reach a new level with the spirit of struggle.

Liu Linzong, deputy secretary of the Party Group of China Aviation Engine Group Corporation: Really made the party building work on the main battlefield independently developed by aviation engines, and explored a new way for party building integration into the center. Not only the ideal and beliefs, but also the heart of the officer to start a business, but also the heart of the aviation equipment.
