Chapter 359: Farm Vehicle and A-4 Skyhawk Attack Aircraft, a Miraculous Encounter in Heifei
With Mr. Hu as a contact, the issue of buying an airplane was quickly resolved. There would be no problem in applying for entry as long as there was no ammunition, and there would be no problem in applying for flight according to aviation control.

But there is one thing: once you get in, it will be difficult to get out.

Fortunately, Ren Zhong did not think of bringing this thing back to China. On the one hand, it was too sensitive. On the other hand, there was no need for it. Technically, it was already decades old.

Now even the JF-17 in China is several generations ahead of it!

Considering the impact, F-4H will not be displayed to the public for the time being. TA-4 will be used as the endorsement of Yunlong Automobile, and it will be directly named Yunlong! It will be placed in the factory where Yunlong agricultural vehicles are produced by the joint venture, so that everyone who visits can see it, and in newspapers and short videos, this will be used as a gimmick to build the personality of the product.

Linking Yunlong agricultural vehicles with airplanes at once shows the strength of Yunlong Automobile.

Taking advantage of the opportunity, the company launched the Yunlong Y-3 pickup truck, which has the core of an agricultural vehicle and the appearance of a pickup truck. It is equipped with a 1.8-liter diesel engine, has a maximum design speed of 75 kilometers per hour, and a cabin load capacity of 750 kilograms.

The Y-3 carriage is further lengthened by 1 meters.

The price is only 25888! It is still priced in RMB, which is 3698 US dollars when converted into US dollars, which is directly above the price of a local second-hand car that is more than years old.

But it has the functions of a smart car such as a large smart screen, dual-electric power, reversing image, WiFi connection, etc.!

This is simply a dimensionality reduction blow!
However, Ren Zhong didn't care about these things. He just wanted to find a way to get the technology of the two fighter jets back.

In order to solve this problem, Ren Zhong called his two senior brothers Li Shaoxin and Wu Jiancheng and asked them to find a way to form a tape measure team. With their connections, they could find an aviation tape measure team in Jincheng. Although it was a little difficult, with the addition of Grandpa Cao, it would be a problem. Grandpa Cao was familiar with most of the most technically skilled retired old men in Jincheng, so they soon put together a black and white travel team.

Among these people, there are veterans from the J-7 production line, retired engineers who worked on the design of the Xiaolong, veterans who worked on avionics and the turbojet 13F afterburner engine, and even a PhD in materials science.

I went there with a tape measure and a wrench.

A-4 attack aircraft

Although it is not necessary to disassemble and reassemble the two fighters, the difference is estimated to be not much. It may be a bit difficult to ask these old guns to go through the F-22, as many things may be difficult to identify. But if you ask them to deal with two second-generation aircraft, some of them have been dealing with J-7 for half their lives, so they are very familiar with second-generation aircraft. Although these are two systems, many concepts and practices are similar.

Physical measurement and obtaining accurate three-dimensional data is only the first step. Ren Zhong looked at the introduction materials of the various components of the F-4, which involved so many new materials and new processes. That was really despairing. Fortunately, he is not working alone now. For some things now, he only needs to take back the general concepts and ideas, and the team below can quickly produce results.

But these achievements do not include anything related to jet engines.

Even after decades, the technical data of the J79 jet engine is still confidential, and Ren Zhong has no access to it. Even if the actual object can be obtained, for an engine, size and shape are only about % of its secrets.

Most of the secrets are buried in the underlying materials. For example, super-high temperature alloy materials are really daunting.

These things are technologies that cannot be bought with complete processes even if you have money. Fortunately, there are some professors of materials science who are researching this area. The basic laboratory production processes and samples of the first, second, and even third generation high-temperature crystal materials have been popularized, allowing Ren Zhong to buy some practical technologies and take them to the world of Sword and Fairy for further research and development of mass production process production lines.

Of course, it is not realistic to break through to the third generation in one step, and many of the experimental instruments in the laboratory are not currently available in the world of Bright Sword.

At present, the international smelting methods of high-temperature alloys mainly rely on three major artifacts: vacuum induction furnace (VIM), vacuum consumable furnace (VAR), and electroslag remelting furnace (ESR).

Ren Zhong has just completed the introduction of electroslag remelting furnace technology from the main world. The application range of electroslag remelting furnace is very wide. It can not only be used to produce aviation bearing steel, high-temperature alloys, precision alloys and certain non-ferrous metals, but also to produce large high-quality alloy steel ingots weighing hundreds of tons, large flat ingots or plate ingots, hollow steel ingots, composite plates, as well as melt-casting rolls, gear blanks, turbine disks, pressure vessels, aircraft landing gear, gun barrels and other special-shaped castings.

For the current Longguo, this is a tool with the highest technological content at present, especially for turbine discs, aircraft landing gear and other special components that are urgently needed for aircraft. There is almost no alternative technology to complete them now.

From the 3-ton electric slag remelting furnace to the 10-ton electric slag remelting furnace, Ren Zhong spent tens of millions of consulting fees in the main world before he mastered this key technology in the world of Bright Sword. Now there are more than 200 electric slag remelting furnaces distributed across the country, with an annual output of nearly 200 million tons of electric slag steel, which meets the needs of special steels such as tanks, cannons, aircraft landing gear and train wheels.

To manufacture high-temperature alloys now, a vacuum induction furnace (VIM) is necessary. The smelting process of new high-temperature alloys represented by powder high-temperature alloys is still a very cutting-edge research technology even in the current situation of the main world. In the world, the powder high-temperature alloys of Dama use VIM or VIM+VAR double smelting process, and the powder high-temperature alloys of Liumao use VIM+ESR+VAR triple process. Obviously, the effect and the final product are also leading the world.

As for Longguo itself, the domestic powder high-temperature alloys have basically just evolved to the VIM single refining process, which results in the purity of powder high-temperature alloy materials being lower than the advanced foreign level.

The good news is that we have the basic models, so Ren Zhong can spend money to buy the manufacturing technology of vacuum induction furnace (VIM) in China, and he can also get some outdated model manufacturing technology of vacuum consumable furnace (VAR), but he may not be able to buy the triple process.

With the current level of the world of Bright Sword, we should be thankful if we can achieve solo training.

Fortunately, J79 is from the middle of the last century, and its technological level is considered ancient in the current main world. Once the high-temperature alloy is solved, half of the problem is solved. After all, the turbojet 5 has been developed in the world of Bright Sword. In principle, it is not unattainable to break through J79 with the new technology.

If this engine breaks through, Ren Zhong believes that the Dragon Country Air Force will be ahead by at least 20 years! After all, this is a real big push! Even in the Rogue Eagle's own sequence, it has been used from the F-4 to the F-16 decades later before its mission came to an end.

If it reappears in the world of Bright Sword, it will be a landmark event for Longguo, which means that from heavy fighters like F-4 to light fighters like J-7, they can all be easily driven by this engine. It's just that one chooses twin engines and the other chooses single engines.

In this way, with the high-low coordination of F-4 and J-7, the sky of Dragon Country will be as stable as a rock for at least twenty years.

Of course, in Ren Zhong's mind, the J-7 is no longer a copy of the initial version of the Mig-21, but the latest FTC2000G version that has been modified to the point that even Mikoyan-Gurevich would not be able to recognize it!

Although it is impossible to make the avionics and radar so powerful, Ren Zhong has the opportunity to copy the appearance back to the world of Bright Sword.
