Rebirth of the Auto Giant

Chapter 575 International Advanced Level

"How long do ordinary aircraft tires last?" Wang Shi said, looking at the tires on the ground that had been tested 32 times.

"Chairman, the replacement of aircraft tires is not calculated based on time or mileage, but also based on the number of flights. Aircraft tire wear is mainly during takeoff and landing, and everything is calculated based on the number of aircraft. Generally, they need to be replaced after 200 to 250 flights.

New baby." Fu Chuanli said.

"Basically, it can be used continuously for about a month?" Wang Shi said.

"Yes, it depends on the specific tread wear. The winter may be longer, about two months." Fu Chuanli responded.

"So, the profits here are not low." Wang Shi thought.

"That's right, otherwise the technology that can currently produce aviation tires is blocked by the monopoly technology of several European and American companies. Moreover, the steel wires and nylon ropes in the old tires that were replaced for the first time have not reached the level of fatigue and are within the usable range.

Just do a little refurbishment and replace the upper layers of tread with new ones." Fu Chuanli added.

"Retreaded tires?" That's not okay.

Isn't this just like retreading car tires?

Seeing Wang Shi's surprised words, Fu Chuanli added: "Wang always thinks of retreading tires for cars, right?"

Seeing Wang Shi nod, Fu Chuanli continued: "Aircraft tires, because the materials used are stricter than those of cars, are unmatched in quality by car tires. They use high-strength steel wire beads and high-strength nylon ropes."

The carcass layer has not yet reached its fatigue level. For tires that are replaced for the first time, you only need to retread the rubber surface of the tread."

"This retreading is different from the retreading of car tires outside. This is allowed on aircraft tires. This is a better way to save materials, improve material utilization and save costs." Fu Chuanli said.

Understood.

In other words, this retreading is based on the high-strength steel wire, nylon rope and other high-strength materials used in aircraft tires. In theory, the new tires only take off and land for 200 to 250 flights, which does not reach the fatigue level of these materials. In the original

It is possible to renovate the factory.

"Is the selling price more favorable?" Wang Shi asked.

"Hey." Fu Chuanli said hey twice but said nothing.

You know, it’s called recycling.

"Test this to the number of 250 flights and see the results." Since it is the number of takeoffs and landings of 250 flights, then use this number to see what the final result is.

"Okay." After Fu Chuanli finished speaking, he waved to the employees and put the tires on the inspection stand again. The huge flywheel of the dynamometer slowly started to rotate again, faster and faster. When the speed reached 400 kilometers per hour, the tires

When the tire surface comes into contact with the flywheel, a huge friction sound is heard, and a stream of white smoke rises from the tread, which is the smoke produced by the friction of the 75% heat-resistant natural rubber tread.

Next to Wang Shi, two beauties, Zhao Min and Li Yue, looked on while wearing safety helmets like everyone else.

"How do you feel?" Wang Shi looked at Li Yue and asked.

Li Yue is a flight attendant and can be considered a member of the industry.

Guyan

Although Li Yue is a flight attendant, she has never seen how airplane tires are made. She said magically: "I have never seen it before, and I never thought that an airplane tire is made in this way, and such nylon ropes and steel wires are used."

."

Fu Chuanli now also guessed the identity of the beautiful woman next to Mr. Wang. After hearing Li Yue's words, he introduced: "Just talking about the nylon rope we use, a small nylon rope can lift a child weighing two hundred kilograms."

Heavy

The density of a tire is an average of 10 strands of nylon rope per centimeter. In addition, the rubber used is not ordinary, and 75% of heat-resistant natural rubber is used as raw material to withstand the takeoff and landing of aircraft.

."

The workers were testing, but there was no result for a while. Wang Shi turned around and took the two of them to the tire manufacturing production line to have a look.

Finally, the test reached 250 flights.

Everyone gathered around and saw that there was a lot of wear and tear on the treads, and some treads even had debonding that could be seen with the naked eye on the surface of the tires.

"This is within the standard range. If it is more serious like this, then it needs to be replaced and the tread retreaded." Fu Chuanli fiddled with a small piece of raised rubber and said.

In order to make Dongheng Tires comparable with foreign products, Fu Chuanli has even prepared old tires produced by foreign companies that have been replaced by airlines, and put them together.

"This is a tire produced by a famous foreign brand. It was replaced for the first time and has not been refurbished. I had it retrieved for about 250 flights. Comparing the two, ours is no worse than theirs."

"Well, let's hand it over to relevant domestic institutions for testing to see if it meets national standards, and then apply for a product certificate through an authoritative foreign institution. We can't fool ourselves. After we pass it, we have to see if it meets international standards.

You can't be careless." Wang Shi said, "But judging from the current situation, there should be no problem."

"As long as the technology meets the requirements, it's okay if they don't issue a certificate. We don't need their consent. I want them to see that in the future, all products of our Tangfei Company will use Dongheng Company's tires, so that those competitors who look down on us will

Look, we not only have the market, but we also have the technology."

"Without him, Butcher Zhang, we can still eat meat."

Wang Shi said.

"Okay, I'll do it myself. Let's leave now. The results should be available before tomorrow afternoon." Fu Chuanli also knew that Tang Fei's inventory was running low, so he immediately went out in person, got on the plane with two tires, and flew to

Yanjing conducted audits and tests on national standards.

The next day, at nine o'clock in the evening, Dongheng Company released the latest news on its official website.

After unremitting efforts, the only aviation tire in China has been produced and passed the national standard certification.

This news article describes how Dongheng Company received instructions from the chairman of Tang Dynasty Group Company and established a technical research team. Of course, the content also pointed out that it had received support from the government and also mentioned it.

It is illustrated with pictures and text, and includes a comparison of the tread wear of tires that have been tested for 250 flights, compared with foreign tires that have just been replaced by airplanes and have the same number of flights, with pictures and captions.

The picture is very clear.

After t2000 was silent for a period of time, new good news came, which immediately received strong support from the majority of patriotic netizens.

"Well done to Dongheng, you didn't embarrass the people of the country."

"Now the Tang Dynasty Group owns up to 70% of Dongheng Company's shares, and the Tang Dynasty Group is involuntarily involved."

"Come to the bowl."
