This test did not exist because there was a problem with the engine, but because the professors of the test couldn't help it, they wanted to see what the state of the engine was, and they took the initiative to stop the operation of the engine at full afterburner, and then checked.

And the results of the inspection made them a little shocked, after 3 hours of full afterburner, this engine theoretically has no major problems with all the structures! This all says a lot!

That is, its structure and the strength of materials and other strengths cooperate with each other, which makes the structure of this engine extremely stable, which is why it is so metamorphosed.

In short, it's like a computer at the end of the last century, when you install it, you need to protect yourself from dust, static electricity, etc., and you need to bring it to the last computer class.

But what about computers now? After a few years of not cleaning the case, there is a basket of dust inside, but your machine is still running steadily without any problems.

This is what can only be achieved when the structure and material life of the component exceeds the damage caused to it by the environment. They don't know if the Phantom's engine will be able to maintain this performance after breaking through the thermal barrier, but at regular air and speed, this means that its structural and material stability has surpassed that of all existing engines.

After getting this data, the professors immediately made another decision, which was to go directly to the high-altitude test bench and then conduct a destructive test, and perform a full afterburner test on the high-altitude test bench.

The previous routine test results of the high-altitude test bench have far exceeded the data of all other engines in China, and the good ones are simply not good.

In the process of simulating the high-altitude environment, the duration of its full afterburner state has also reached 3 hours, the only difference is that in the inspection process after 3 hours, some of the materials in it have been slightly deformed for the first time, and some state changes.

After seeing that there was a problem with the engine, the old professors in charge breathed a sigh of relief, because the engine that did not have problems was too unreal! If this continues, several old professors themselves are going to have problems, and they can't stand this stimulation.

While the engine tests are underway, the other designs of the Phantom, as well as the various components, are constantly undergoing various tests, especially the kind of composite materials, which can still be built by the state, although the cost is very high.

However, the testing of composite materials has also been carried out countless times, and the testing of materials is relatively simple, and there are many ways to test the limits of various environments, but the more you test, the more you can understand the strength of this material.

After knowing the strength of this composite material, the country has even adjusted the relevant industrial structure, mainly to strengthen the investment in the manufacturing process of this composite material, because from this aspect it can be seen that the main research direction in the future is composite materials.

It has to be said that some domestic systems in this regard are better than those abroad, and this system of concentrating on doing big things can make the breakthrough speed of related processes soar.

Didn't we use this model to catch up in the past?

The overall design of the Phantom fighter has also been completely completed, and the version given by Jiang Yanhai is incomplete, especially in some details, and these aspects are directly completed by the concerted efforts of various professors, and the internal structure design has also been re-optimized.

These designs and optimizations were discussed and demonstrated with Jiang Yanhai, and all of these verifications continued until the end of September.

After more than 3 months of continuous test work, the other parts of the Phantom are easy to say, including the electronic system, which can actually use part of the electronic system of the J20 fighter, after all, the J20 is not completely finalized now, and all the equipment inside has been completely updated.

In the past three months, the engine testing has not stopped, and a total of 10 engines have been maintained on different test benches to maintain various tests, and the money spent in the middle is simply calculated in terms of turnover every day.

Eight engines were damaged in three months, and each engine cost $12 million. The cost of 18 engines is 220 million US dollars, equivalent to about 1.5 billion yuan, which does not count the fuel consumption of these 18 engines in 3 months.

This is a terrifying number, although the fuel is directly calculated according to the cost price, this new type of mixed fuel, because of the refinery purchased by Li Yunfeng himself, its price is about 4,200 yuan per ton.

During these three months, 18 engines were tested almost all the time, and their total testing time exceeded 13,000 hours.

And many test intensities are even several times higher than the previous test intensity, because during the test process, it was found that if the test was carried out according to the previous standard, it would not be meaningful, and it could not get its limit, so it began to increase its test intensity.

In three months, the engine test, the Phantom's other parts test, etc., consumed a total of nearly 3 billion RMB! This means that Li Yunfeng did not hesitate, and directly paid and settled, otherwise, these small countries would not be able to afford to play at all!

This is still the case that Jiang Yanhai has provided almost all the drawings, and the necessary tests alone will cost money, and if the research and development from beginning to end does not have tens of billions of funds, it is impossible to develop them.

After all, a factory has developed an assembled car that purchases more than 90% of the components of other foreign automobile companies and spent 10 billion.

In this comparison, the price is really too low.

At the end of September, it was said that Jiang Yanhai had turned 21 years old and entered 22 years old, but his birthday had not passed, and Li Ruobai had no time recently.

Li Ruobai and these electronics research institutes have also joined forces to carry out the last step of research, and the reason for the research is that at this moment, Jiang Yanhai and Li Ruobai are in front of this fighter!

A Phantom fighter in its original color and in the final stages of assembly!

That's right, the Phantom has been made! The speed is much faster than Jiang Yanhai thought! The main structural materials, including the engine test, have been completed, and the engine test of more than 10,000 hours has exceeded too many standards, especially the strength of many of these tests is too perverted.

The reason why I chose this time to make it out is because this year is a special year, it is the 70th anniversary of the founding of the People's Republic of China, and there will be a military parade at that time.

Of course, Jiang Yanhai and they don't want to appear in such a thing as a military parade, it's impossible, they just have to take a look inside the base.

It's a scene that everyone who is a soldier wants to go to, but they all know that they have a more important mission.

And another important impact of the phantom production is that at this moment, Jiang Yanhai and Li Ruobai can both stand in front of this stealth fighter.
