Even a layman could understand what Qi Mantang meant, so what caused the cracking?
There must be some other fault that affects the pickle fork.
David's reaction was also very fast. He looked very fierce. This time he led the team here. Such obvious defects in the plane were exposed by China. After returning, he would definitely not have a good time. He could only blame China by making unreasonable demands.
"So, what did you do on this plane to cause the pickle fork to break?"
Qi Mantang was practically furious. He turned to the reporters and said, "Please pay attention to what I have to say. I hope BOYING can explain to users around the world why the Pickle Fork was designed to have a lifespan of 90,000 takeoffs and landings, but only 30,000 in reality. If this aircraft has such an obvious design flaw, why hasn't it been improved? Are there other design flaws?"
The safety performance of an aircraft is closely related to every journalist, especially transnational journalists who are frequent flyers. If the aircraft is so unsafe, how can their lives be protected?
David didn't expect the Chinese to be so cunning that they would incite reporters to cause trouble.
You should know that the 737 is currently BOYING's most profitable aircraft. People in later generations also know that this model of aircraft has very high sales volume and is BOYING's star product. Although it is said that there have been modifications and performance improvements, each modification is just a small change to facilitate price increases.
It can be said that BOYING made a fortune from this type of aircraft.
David couldn't help but think of the Red Star Feiteng, which was launched in the first half of the year by China Ice Motors. It was a new car that perfectly replaced the Ford that was about to be put into production. It was like a child that was about to be born but died in the womb.
This seriously damaged Foote's vitality.
The Red Star Yahoo perfectly replaced Eagle Country's luxury brand LR new car, causing Eagle Country's new car, which was launched half a year later, to be stillborn again.
China has twice intercepted two established car brands, severely damaging them. Could this time be targeting BOYING? Is China unable to produce large cars at the moment, so it's using this method to make BOYING lose money?
David was so scared that he broke out in cold sweats. This realization terrified him. The economic situation in the United States is very bad now, with trade deficit, balance of payments deficit, plummeting US dollar, gold outflow, and rising unemployment rate. He didn't want to be homeless.
David raised his fist and attacked Qi Mantang. A Chinese soldier pulled Qi Mantang away and grabbed David's wrist. "Comrade, it's not right to attack!"
David suddenly felt a pair of pliers clamping his wrist. His face turned pale with pain and cold sweat broke out. An American officer came over and gestured to the Chinese soldiers, and David was released.
The American officer was very angry and yelled at David, asking him why he attacked the Chinese when it was clear that the Chinese did not attack him.
Once a conflict occurs, it is obvious that the US soldiers are not at an advantage, and Russia will definitely not help them. The best situation is that neither side helps each other. However, this place is close to the border of China, and the other side can fire a shell at us.
In the eyes of American officers, David is just a dead dog that can't think.
"They slandered this plane. I am a senior engineer of BOYING Company. I will not allow anyone to slander my company!" David said righteously.
Qi Mantang had someone to back him up, so he was confident. "Haha, the evidence is right here. Do you really think that this plane was shot down by a Chinese artillery shell?"
David said angrily, "Why not? This isn't the first time you've done this!"
Someone behind him cheered, "That's right, just last year, you shot down eight of our planes in one go!"
Qi Mantang was so angry that he almost laughed. He said to the American officer, "Sir, please tell your compatriots that what we shot down was not a civilian airliner, but a fighter jet that was bombing in our airspace!"
The American officer's face turned completely black, and he glared at David fiercely. He was afraid that David didn't understand his curse words.
At this moment, a Russian expert came over carrying a piece of engine debris. He was unaware of the dispute and said objectively, "I think there's a problem here!"
No one cared about fighting anymore and they all gathered around. Qi Mantang gestured to the Chinese soldiers, who squeezed into the crowd and took a photo of the fragment.
This is a digital camera contributed by Ji Xia. It has high pixels and its clarity is much higher than the best SLR camera today.
Therefore, the circle of tooth marks on the fragment was photographed very clearly.
"Where did these teeth marks come from?" Qi Mantang pointed suspiciously. "What kind of tool was used to tighten it here?"
It was normal for Qi Mantang to have such doubts. He was not a boying person and was not familiar with the materials and craftsmanship used on the aircraft.
The BOYING engineers all looked grim. Meanwhile, the Russian expert carefully examined the debris and analyzed the surrounding debris. He raised his own question, "Based on my experience, the tear point should be here. Judging from the tear pattern, I suspect the aircraft resonated while flying at high altitude!"
"Impossible!" David objected, and Anne nodded. "Obviously, no matter what industry we're in, the first thing we have to avoid during the design phase is resonance!"
The Maozi expert nodded. "Indeed, but the circle of tooth marks here is very unusual. I don't know what kind of tool would leave such tooth marks, but it's clear that these tooth marks may change the natural frequency of this part, and thus the natural frequency of the engine."
Once the engine and the fuselage resonate, the consequences will be unimaginable.
When Ji Xia taught at the research institute, he avoided the issue of resonance.
This also led to the fact that when the Russian experts proposed this idea, they were all confused, and this silly look was also noticed by the Americans.
Annie still found it hard to believe, and the Russian expert didn't force her. He handed the fragment to the American and said, "Can you do a fault simulation?"
That is, use a new part, carve a tooth mark at this place, and then measure the natural frequency of this part and the engine.
If the final analysis results point to the cause of the plane crash, then we need to trace how this scratch came about. No matter how we trace it, it cannot be intentional.
Because, in order to cause a plane crash in this way, not only does one need a powerful computing brain that can reversely calculate how deep the scratches should be to change the natural frequency of the parts, thereby changing the natural frequency of the engine to be consistent with the fuselage, but one also needs a set of 737 parts drawings.
Behind the hotel where the Americans were staying, a tall man in a leather coat was negotiating with the waiter in the hotel. He secretly handed a wad of money to the waiter, handed her a small button, and then hurried away.
