Chapter 892

This test does not exist because there is a problem with the engine, but because the test professors can't help it. They want to see what the engine is in. They take the initiative to stop the engine at full power and then check it.

They were a little shocked by the inspection results. After running at full power for 3 hours, theoretically speaking, all the structures of the engine have no big problems! All this shows a point!

That is, its structure and material strength cooperate with each other, which makes the structure of the engine extremely stable, so it is so abnormal.

In short, it's like a computer at the end of the last century. When installing, you need to prevent dust, static electricity, etc. you need to bring foot covers in a computer class.

But what about computers now? If you don't clean the chassis for several years, there are a lot of dust in it, but your machine still runs steadily without any problems.

This is the effect that the component structure and material life have exceeded the damage to it by the environment. After the phantom breaks through the thermal barrier, they don't know whether the engine can maintain this performance, but under normal air and normal speed, this means that its structural and material stability has exceeded all existing engines.

After obtaining such data, these professors immediately made another decision, that is, go directly to the high-altitude test bench, then carry out destructive test, and carry out full force test on the high-altitude test bench.

The routine test results of the previous high-altitude test-bed have far exceeded the data of all other engines in China, which is simply outrageous.

The full force test on the high-altitude test bench also made everyone extremely satisfied. In the process of simulating the high-altitude environment, the duration of its full force state also reached 3 hours. The only difference is that in the inspection process after 3 hours, some materials inside had slight deformation and some state changes for the first time.

After seeing that the engine had a problem, the old professors in charge were slightly relieved, because the engine without a problem was too unreal! If this continues, several old professors will have problems themselves and can't stand the stimulation.

While the engine test is carried out, other designs of phantom and various components are constantly tested, especially the composite material, which can still be built by the state, although the cost is very high.

However, countless tests have been carried out on composite materials. The test of materials is relatively simple. There are many methods for limit test in various environments, but the more the test is, the more we can understand the strength of this material.

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

It has to be said that some domestic systems in this regard are better than those in foreign countries. This system of concentrating on doing great things can make the breakthrough of relevant processes fast.

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

The overall design of the phantom fighter has also been completely completed. The version given by Jiang Yanhai is not complete, especially in some details, which are directly completed by the concerted efforts of various professors, and the internal structure design has been optimized again.

These designs and optimizations were discussed and demonstrated with Jiang Yanhai, and all the verification lasted until the end of September.

After more than three months of continuous testing, other parts of the phantom are easy to say, including the electronic system. In fact, some J20 fighter electronic systems can be used. After all, J20 is not completely finalized now, and all the equipment inside has been completely updated.

In the past three months, the engine test has not stopped. A total of 10 engines have been maintained on different test stands. The cost is calculated by running water every day.

Eight engines have been damaged in three months, and the cost of a single engine is US $12 million. The cost of 18 engines is US $220 million, equivalent to about rmb1.5 billion, which does not count the fuel consumed by these 18 engines almost continuously in three months.

This is a terrible figure. Although the fuel is calculated directly according to the cost price, the price of this new mixed fuel is about 4200 yuan per ton because of the refinery purchased by Li Yunfeng.

During these three months, 18 engines were tested almost at any time, and their total test time had exceeded 13000 hours.

Moreover, many test strengths are even several times higher than the previous test strength, because it is found that if tested according to the previous standards, it will have no meaning and can not get its limit, so it began to increase its test strength.

In three months, the engine test and other parts test of phantom consumed a total of nearly RMB 3 billion! This means that Li Yunfeng paid directly without any hesitation. Otherwise, these small research countries simply can't afford to play!

When Jiang Yanhai provided almost all the drawings, only the necessary tests cost money. Without tens of billions of funds for R & D from beginning to end, it is impossible to develop it.

After all, a factory has developed an assembly vehicle with more than 90% of the components purchased from other foreign automobile enterprises, which cost 10 billion. Where do you go to reason?

In such a comparison, the price is really too low.

At the end of September, Jiang Yanhai was 21 years old and 22 years old, but his birthday had not passed, and Li ruobai had no time recently.

Li ruobai has also joined forces with these electronic research institutes and has been carrying out the last step of research. The reason for the research is that Jiang Yanhai and Li ruobai are facing the fighter!

A phantom fighter with original material color and undergoing final assembly work!

Yes, 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. The engine test for more than 10000 hours has exceeded too many standards, especially the strength of many tests here has been too abnormal.

The reason why I chose to make it at this time is that this year is a special year. It is the 70th anniversary of the founding of the people's Republic of China. There will be a military parade at that time. Now I choose to make it as a gift for the National Day!

Of course, Jiang Yanhai can't think of such a thing as the military parade. It's impossible. They just have a look inside the base.

In such a scene, every soldier wants to go, but they all know they have more important tasks.

Another important impact of the phantom production is that Jiang Yanhai and Li ruobai can stand in front of the stealth fighter.
