On the sixth day, the master company began to investigate the main structure of the aircraft. Looking at the behemoth in front of you, even if it is deformed, you can still feel the delicacy in it. According to Dr. John of the United States, the United States is the only country in the world that can now process such a monolithic component in a huge piece of iron that is more than 20 meters long and three meters high.

According to the density of titanium alloy 4.5, the weight of such an iron ingot is as high as 7,200 tons, and the overall structure processed from it is only a thin 7 tons! Every corner is extremely smooth and the light is recognizable. One building block is enough to make the strong foundation of the United States clear.

Then investigate the cause of the problem, the personnel of the master company openly steal the scientific and technological achievements of the United States, and do not let go of every corner, portable three-dimensional scanning, metal flaw detection and other tools are in battle, and the huge metal structure is scanned into the computer little by little. These numbers, design methods, concepts, etc., are enough for the master company to increase the aerospace design for more than a year out of thin air.

For such shameless behavior of the master company, of course, the United States found out, but they still have the last resort, so they don't care about the small actions of the master company, but the expert team of the master company is really powerful, and every component has been analyzed with defects, these analysis from the master company are equally important to the development of the United States' aerospace.

Technical analysis from another perspective allows the United States to see its own shortcomings from another angle. In addition, the analysis equipment, computers, software, etc. used by master companies also make the United States salivate. It is precisely because of this that the Americans have let go of the technology of letting master companies scan themselves, and they will stay in our country in the end anyway!

Hundreds of people scanned and analyzed a huge component, and it took two days to find the cause. The main reason is that Zhang Jingyuan feels that there can be no problem with the engine, and the problem must be in the United States itself, so as the final main structure, the analysis is even more precise to the limit.

In the tail section of the frame, where the engine was mounted, a less noticeable deformation occurred. According to the analysis, this place was not created after the fall, but deformed at a high altitude.

This is the first time in all the analyses that the cause of the disaster has been clearly identified.

Of course, the experts on the American side are not rice buckets, and after a little analysis, all Americans have a bad face: it is very likely that this disaster is really not the fault of the master company, but its own reasons.

Compared to the original design drawings in the United States, this place is obviously strongly distorted. In fact, as soon as they saw the problem here, the master company analyzed the reason: the engine power was too large, so that the structure could not withstand the huge force and deformed; Under the force of hundreds of tons of thrust, a slight deformation will produce several tons of force to act on the rest of the aircraft, and it is conceivable that under the action of this sudden increase in lateral force, it is not difficult to understand the disintegration of the aircraft. In particular, the aircraft was hitting the ultimate speed of Mach 5 at that time, and the aircraft was still shaking violently, which further aggravated the engine tremor and had a more drastic impact on the architecture.

Finally, after metal flaw detection, metal section analysis, etc., it was finally determined that the cause of the accident of the aircraft had a great relationship with it.

It's just that the Americans have a hard mouth, and they don't know if it's for the sake of face or something else, so they insist on saying that there is a problem with the engine. For this reason, the master company also had to spend a little time analyzing the engine.

It's just that the original engine fell from a high altitude, and the speed was several times the speed of sound, and even the engine of the master company was all in pieces, and the collection was incomplete.

Then test the engine in good condition! In fact, by now, the Americans have understood in their hearts that ninety percent of the problems lie with themselves, but they still have the idea of what if, and still ask the master company to check the engine, and take all the remaining four spare engines in the United States to check.

"Let's just use the dynamic check!" Looking at the Americans, Zhang Jingyuan rolled his eyes disdainfully, "A few are broken, and the master company will make up for a few!" ”

All four engines were placed on the real platform, not only running at full power, but also on the test bench, vibration testing was carried out in strict accordance with the highest standards of aerospace.

Of course, in this process, because it is in a real environment, the heat dissipation of the engine will be much better, and the lubricating oil needs to be changed every 24 hours. Seven days of uninterrupted operation, and all kinds of test vibrations have been maintained, except for 8 oil changes, the engine is intact.

It is already obvious that the cause of the accident is actually the Americans' own products!

Zhang Jingyuan led the team to analyze the key points of the accident and came to the conclusion: smart is mistaken by smart!

Yes, the Americans think that their technology is good, but they have planted a problem with it.

It turns out that in the overall architecture, the position of the carrying engine is really a little fragile; The original design was more reasonable, but the Americans, relying on their own strong technology, reduced the burden on the support frame for the key position! Through the guò hollowing process, the overall structure has been reduced under the guarantee of basic strength.

This kind of burden reduction, under the static action is not any danger, after all, it has been carefully calculated, but the flight of the aircraft, is a dynamic process, in the violent shaking, so that the stress concentration is difficult to diffuse, and the final result of the guidance is the gradual accumulation of stress, and the final guidance of the structural deformation, and then directly caused this air crash.

This kind of behavior typically explains what it means to be smart but mistaken by smart! Believing too much in your own technology has led to such a result.

It wasn't just a simple plane crash, it cost the United States a lot of money; The most important thing is to make the people's minds float!

At present, many people are shouting that they will severely punish the high-quality companies that sell inferior products, and even some Americans are shouting the slogan of expelling inferior goods from China. For this reason, Huaxia Capital in the United States suffered a sudden outbreak of resistance, and the losses received were really considerable.

Looking at the report on the table, the President of the United States frowned a little, things are big! In addition to the problems here, the products of the master company, under the most demanding conditions, are still perfect.

However, the difficult thing now is, how to account for the people? Don't you tell everyone: don't get angry, it's not the reason of the master company, it's our own reason! Is it possible? Just think about it and you can see the consequences!

So, continue to press and not report for duty? That won't work either! The master company will definitely poke it out! At that time, the consequences will be even more severe. For the first time, the president of the United States admired China's strong speech control and hated American freedom and democracy.

"Negotiate with a master company!" Suddenly, the president of the United States came up with such an idea, can this matter make the master company take the blame? Not a frame-up, of course, but an insider deal! Now the master company, the United States really does not dare to go to the black hand!
