High-cold test flights, low-temperature test flights...many domestic aircraft models begin their first flights in the new year

　　Since the beginning of this year, a number of domestically produced aircraft models have started their "first flights in the new year" across the country, which is rare in the history of our country's aviation industry.

　　Among them, the amphibious aircraft plans to obtain airworthiness certificate this year, and is currently seizing the time to conduct test flights before obtaining the certificate. This also means that it is one step closer to being put into market application.

　　Today, we followed reporters as they approached a number of domestically produced aircraft models undergoing test flights.

　　In Mohe, a domestically produced 13-ton large civil helicopter launched its first high-cold test flight.

　　In Suining, the MA-60 fire extinguisher launched an ultra-low altitude water drop test flight, one step closer to being put into actual combat.

　　In Jiamusi, two types of domestic helicopters "joined" the Northeast to jointly carry out low-temperature test flights.

　　In Hailar, my country's largest amphibious aircraft AG600M under development is also struggling to conduct low-temperature test flights. This period is the only test flight opportunity this year before obtaining certification.

AG600M test flight site commander Zhao Yuhe, deputy general manager of Aviation Industry General Aviation South China Company:

The temperature during this period is the last window we can seize this year.

　　This year is a critical year for the airworthiness certification of the AG600M aircraft, which is a necessary condition for its application. For this reason, the test flight team rushed to Hailar at the end of January. In order to successfully complete the test, the flight test team formulated a strict schedule and planned to complete the low-temperature test of the three major systems and four flight tests in 10 days.

AG600M test flight site general commander Zhao Yuhe, deputy general manager of Aviation Industry General Aviation South China Company:

The rhythm is very tight. Here we are doing the heating test after the engine is cooled, and the other group is also doing the door opening and closing test. These can be done in parallel. as parallel as possible.

Lu Yang, deputy director of the Flight Test Center of AVIC South China Company:

We basically enter the site at 7 o'clock or 7:30 every morning. Depending on the situation at night, we are not sure what time we can go back.

　　However, when we first arrived in such a cold place, and as soon as the plan was implemented, something unexpected happened. The flight test team had just finished the hatch test when the taxiing test encountered a big problem.

　　It turned out that Hyrule had been extremely cold those days, and a yellow cold wave warning had been issued. Before, it only took three or four hours to prepare for the test, but now it took twice as long, which greatly delayed the completion of the daily tasks.

Dong Hao, deputy captain of the AG600M Maintenance Group, Aviation Industry Flight Test Center Maintenance Department:

If this link is postponed indefinitely, a lot of subsequent work will have to be postponed.

　　The last window must be completed within 10 days, but the plan cannot keep up with the changes. What should I do? Everyone decided to use a stupid way to get the time back.

Reporter:

How many people are coming to work overtime tonight?

AG600M air mechanic Zhang Pengfei, flight test center maintenance officer of Aviation Industry General Aviation South China Company:

more than 20. After waiting for the plane to leave, we basically drove every 2 and a half hours.

　　Everyone in the team knows that as soon as the Spring Festival is over, they will immediately go to the northwest to do a strong crosswind test, and then they will do a plateau test flight. Every plan is very important, and there is no room for delay. Therefore, although tired and cold, everyone worked hard to do their job well.

　　In the end, with the efforts of everyone, AG600M successfully completed all tests in 10 days and ended the field work ahead of schedule.

Dong Hao, deputy captain of the AG600M Maintenance Group, Aviation Industry Flight Test Center Maintenance Department:

They are all his own "children". It can obtain certificates one month earlier, even one day earlier, and it will be delivered to users one month or one day earlier, which will definitely make them very proud. (CCTV reporter Cui Xia, Xu Jing and Yang Xiao)
