The failure of the C919 test flight raises doubtsWhat do those who question China's domestically produced large aircraft think?
Previously, in the field of aviation, most of the technology was dominated by the former United States and some Western countries, especially Boeing and Airbus, which may be more reminiscent of Boeing and Airbus, whose monopoly in the global market gives them a big voice.
With the advent of the C919 domestic large passenger aircraft, this monopoly has been broken, and now the C919 test flight has failedFor these"Singing and declining"What do the Chinese think of the remarks of domestic aircraft?
The development process of C919 domestic large aircraft.
First of all, it is necessary to understand that the C919 is the first domestic aircraft, and due to the relatively short history of development in the aviation field, some equipment, including engines, is not a Chinese product.
For example, the LEAP-1C engine for the C919 is manufactured by CFM International, a U.S.-French joint venture between General Electric of the United States and Safran of France.
It is worth mentioning that the LEAP series engines have also been produced in Type A and Type B, which are installed on the Airbus A320 and Boeing B737 MAX respectively, and are very popular in the aviation field.
The emergence of the C919 has refreshed China's strength in the field of aviation, although it is not a domestic engine, but it can be modified using China's aviation technology.
As early as 2018, the C919 completed its first test flight, ushering in the world's recognition and favor of China's C919, and also brought a total of more than 1,200 orders for C919 around the world.
Naturally, this shocking news not only makes our country go further in the field of aviation, but also makes the expectations of the Chinese people continue to rise, making everyone feel excited.
In 2023, that is, just before that, the C919 received bad news, that is, the first B-919A production aircraft delivered to China Eastern Airlines encountered a problem with a left engine failure during the test flight stage in Beijing and a flight to Hefei.
Since there was no response from COMAC, after a few days of fermentation, this bad news gradually became scandalized: first, the B-919A mass production aircraft"Crash landing"Shanghai Hongqiao?
Second, the potential safety hazards caused by engine problems have begun to be solvedAnd then there is"It took 20 years to be a transport aircraft before it became a passenger plane"、"Not as safe as Boeing", even"No one dares to sit unless they are equipped with a parachute"Target**.
All these points are unfounded"Empty words"！
I have to say that these ** communicators make people feel at a loss, they first struggled with professional knowledge, and then argued, and then we told the truth.
First, the C919 took off from Shanghai Hongqiao Airport to Beijing Daxing, and on the next flight from Beijing Daxing to Hefei, there was a problem with the left engine. This is not a crash landing!Not a forced landing.
Secondly, the C919 took off from Beijing Daxing Airport, even if you don't understand mechanics, can you look at the map?Which is farther from Beijing Daxing Airport?What is called"Forced landing at Shanghai Hongqiao Airport"？!!
In addition, the C919's left engine thrust reverser failed. As we all know, thrust reverser is used to slow down aircraft when they land, and when the runway is long enough, even without thrust reverse, a safe landing can be achieved by braking only on the wheels off the frame.
You must know that there are three braking methods for large passenger aircraft, namely engine thrust reversal, speed brake and wheel braking, of which the braking effect of engine thrust reversal is only 5%, which shows that the impact of this so-called failure is not large.
Not to mention, the essence of a test flight is to recover, find problems, and then solve them. Otherwise, why is it called"Test flights"？Otherwise, why is it called"Test flights"？
Those"Singing and declining"What do the Chinese think about domestic aircraft?
In fact, maybe these people are not Chinese, and there is no meaning to depreciate, you know, C919 during this time, although it suffered the impact of **, but some things also happened, such as"The train overturned in the United States, and a large amount of vinyl chloride leaked and deflagrated"Wait!
However, in this case, it can subside in a short time, as if"Sinking into the sea"I think everyone knows why, after all, the incident itself was not a glorious thing for the United States in the past.
And for the ** trend to follow"Don't be suspicious of the big profits"In principle, the former United States undoubtedly realized its great vision in the face of the failure of C919 delivery, which we can all understand.
Of course, we don't rule out a part of it either"Pessimist"The group is a countryman, but we prefer to believe that these people are the been"Carnival rhythm"so they don't know the truth, but I hope this part of the population will follow"Not knowing the truth, however, we hope that these people will follow it"Don't know the truth, don't speak"principles.
Finally, there is some good news, that is, China's self-developed Yangtze River 2000 motor car turbine engine has completed testing, and it should be put into mass production in the second half of 2023 or 2024, and I believe that the domestically controlled C919 will also be on the market soon!
