Chapter 160 Don’t care about me!


On the sixth day, Gaoshou Company began to investigate the main structure of the aircraft. Looking at the behemoth in front of me, even if it is deformed, I can still feel the exquisiteness within it. According to the proud statement of Dr. John from the United States, only the United States in the world can now process such an integral component from a huge iron rod that is more than 20 meters long and three meters high.

Calculated based on the density of titanium alloy 4.5, such an iron ingot weighs as much as 7,200 tons, but the overall structure processed from it only weighs a light 7 tons! Every corner is polished extremely smooth, and the light is discernible. One component is enough to clearly show the strong foundation of the United States.

Then investigating the cause of the problem, the personnel of Gaoshou Company openly stole American scientific and technological achievements, not sparing every corner. Portable 3D scanning, metal flaw detection and other tools were used to scan the huge metal structure into the computer bit by bit. . These data, design methods, concepts, etc. are enough to increase the aerospace design efforts of the master company for more than a year out of thin air.

Of course, the United States discovered the shameless behavior of Gaoshou Company, but they still had the last resort, so they did not care about Gaoshou Company's small actions. On the contrary, Gaoshou Company's expert team was indeed awesome, and every component was analyzed. Despite the shortcomings, these analyzes from expert companies are equally important to the aerospace development of the United States.

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

Hundreds of people scanned and analyzed a huge component, and it took two days to find the cause. Mainly because Zhang Jingyuan felt that there could be no problem with the engine. The problem must lie with the United States itself. Therefore, as the final main structure, the analysis was even more precise to the micron.

At the rear of the frame, where the engine is installed, there is less obvious deformation. According to analysis, this place was not created after falling, but was deformed at high altitude.

This is the first time in all the analyses, that the possible cause of the disaster has been clearly pointed out.

Of course, American experts are not useless. After a little analysis, all Americans look a little unhappy: It is very possible that this disaster is really not the fault of the master company, but the fault of themselves.

Compared with the original American design drawings, this place is obviously strongly distorted. In fact, as soon as they saw the problem here, Gaoshou Company analyzed the reason: the engine is too powerful, so that the structure cannot withstand the huge force and deforms; under the force of hundreds of tons of thrust, even slight deformation will occur. Several tons of force will be generated on the rest of the aircraft. It is conceivable that under the sudden increase in side force, it is not difficult to understand that the aircraft will disintegrate. Especially at that time, the aircraft was hitting the ultimate speed of Mach 5, and the aircraft was still shaking violently. This situation further aggravated the shaking of the engine and had a more severe impact on the structure.

Finally, after metal flaw detection, metal cross-section analysis, etc., it was finally determined that the cause of the aircraft accident was closely related to this place.

It's just that Americans are very tough-talking. I don't know whether it's for the sake of face or something else, but they insist on saying that there is something wrong with the engine. For this reason, the master company also had to spend some time analyzing the engine.

It's just that the original engine fell from a high altitude, and the speed was up to several times the speed of sound. Even the engines of the master company were all broken into pieces, and the ones collected were incomplete.

Then test the intact engine! In fact, by now, Americans have understood that 90% of the problem lies with themselves, but they still hold on to the idea of ​​​​just in case. They still want the master company to check the engines and take over all the remaining 4 spare engines in the United States. examine.

"We will directly use dynamic inspection!" Looking at the Americans, Zhang Jingyuan rolled his eyes disdainfully, "If a few units break down, the expert company will repair them!"

All four engines were placed on the test bench. Not only were they running at full power, but the vibration test was also carried out strictly in accordance with the highest aerospace standards on the test bench.

Of course, during this process, because it is in an experimental environment, the engine's heat dissipation will be much better, and the lubricating oil needs to be replaced approximately every 24 hours. It has been running for seven consecutive days without interruption and has maintained various test vibrations. Except for changing the lubricating oil 8 times, the engine is intact.

It was already obvious that the cause of the accident was actually that the Americans' own products were not up to standard!

Zhang Jingyuan led the team to analyze the key points of the accident, and came to the conclusion: cleverness can lead to mistakes!

Yes, Americans think their technology is very good, but they stumble on it.

It turns out that in the overall structure, the position that carries the engine is really fragile; the original design was relatively reasonable, but the Americans relied on their strong technology to reduce the burden on the support frame at key positions! Through the hollowing process, the overall structure has been reduced in load while ensuring basic strength.

Such load reduction does not cause any harm under static effects. After all, it has been carefully calculated. However, the flight of an aircraft is a dynamic process. In the violent vibration, the stress concentration is difficult to spread, and the final result is It was the stress that gradually accumulated and eventually led to structural deformation, which directly led to this air crash.

This kind of behavior is a typical explanation of what it means to be smart but be misled by your cleverness! Believing too much in one's own skills actually resulted in this result.

This is not just a simple air crash, but it has cost the United States a lot of money; and most importantly, it has made the national mind wander!

Now, many people are already shouting for severe punishment of expert companies selling inferior products, and some Americans are even shouting slogans to expel China's inferior products. For this reason, China Capital in the United States encountered a sudden burst of resistance, and the losses it suffered were considerable.

Looking at the report on the table, the President of the United States frowned a little. The matter was serious! After being troubled for a long time, except for the problem, the products of the master company still passed perfectly under the most demanding conditions.

But the difficult thing now is how to explain it to the people? Should I tell everyone: Don’t get angry, it’s not the fault of Master Company, it’s our own fault! Is it possible? Just think about it and you will know the consequences!

So, continue to suppress and not report? That won’t work either! The expert company will definitely poke him out! The consequences will be more serious by then. For the first time, the president of the United States envied China's strong speech control and hated the freedom and democracy of the United States. "Negotiate with the expert company!" Suddenly, the President of the United States came up with this idea. Can the expert company be blamed for this matter? Of course not framed, but through insider trading! Today's master companies, the United States really does not dare to do evil things!
