Chapter 1364

And that's why only the top five hooligans of the Security Council can play in the high altitude simulation test bed.

Because most of the time, this kind of toy that only big countries are qualified to start is not decided by technology and capital, but whether they have the ability of independence.

For example, Japan and Germany are not short of capital and technology. Even the energy sources that are a headache for many countries can be easily solved by these two countries if they are willing to. After all, the developed nuclear power can completely solve this problem.

But the key problem is that Japan and Germany have original sin. The US military stationed in the two countries' territory is not for dry food. How can you develop the advanced aviation industry and compete with the US father for food?

So let alone the fact that the two countries want to build high-altitude simulation test-bed, that is, the general aircraft engine test-bed, the American father is not willing to do it.

Of course, Americans don't say that they don't want Japan and Germany to enter the aero-engine industry. It's just that when the two countries make breakthroughs in a certain key field, there will always be one or another, which will directly interrupt your progress.

In fact, the situation in Brazil is similar to that in Japan and Germany. After all, it's the backyard of the Americans. The natural influence is there. If you want to climb to the high end of the industrial chain, the American father can kick it at will.

As for India, from a geopolitical point of view, it is much better than Japan, Germany and Brazil. The problem is that apart from being able to say things with one mouth open, India has nothing to do with other aspects. It needs capital without capital, technology without technology, and the most important thing is power. It also threatens to produce high-performance domestic aeroengines before the 1920s, In addition to cheering up India's brainless domestic people, it's basically a joke.

The vision turns back to China's high altitude simulation test bed.

The investment and technical difficulties were so great that China Tengfei didn't plan to build it by itself at first. After all, in 1995, a high-altitude simulation test bed named "equipment-01" was built in the mountainous area of northern Sichuan in the southeast of cotton. The simulation test bed was built in the mid-1960s, which is a part of the third line construction. Due to the huge investment and the complicated technical difficulties, it is difficult to build, After three decades of unremitting efforts of two generations, the construction was finally completed in the 1990s.

The whole project covers an area of 400 mu, with a total installed power of 220 MW, or 2.2 million KW.

What's the concept?

The total installed capacity of the Gezhouba Water Control Project completed in 1988 is only 2.71 million kilowatts. The power consumption of a "equipment-01" high altitude simulation test rig is almost equal to that of a Gezhouba hydropower station. It can be seen that the high altitude simulation test rig is an old power plant, and it has the rhythm of how much it has.

But even so, compared with the other four rogue high-altitude simulation test-bed in the same period, the "equipment-01" high-altitude simulation test-bed is not enough to see. After all, the cabin diameter of the largest high-altitude simulation test-bed is only 3.7 meters, the air flow can only be 120 kgs, the simulation environment can only be maintained at an altitude of 200 million meters, and the speed is only Mach 2.4.

Compared with the United States and Russia, the speed above Mach 3 at 30000 meters can only be regarded as a younger brother.

Even so, the "equipment-01" high altitude simulation test bed is immeasurable for the development of domestic aero-engine. Because of this, after the completion of the "equipment-01" high altitude simulation test bed in 1995, vortex jet-7, vortex jet-13“ The imitation model of "Spey" engine is "Qinling"; New turbofan-6; Imitate the vortex shaft-8 and vortex shaft-13 made in France; Taihang heavy turbofan engine just put into development

It can be said that the whole domestic aero-engine has flocked to the newly completed "equipment-01" high altitude simulation test bed in northern Sichuan, and they are ready to make up for the shortcomings of their own aero-engine with this set of advanced test equipment.

At that time, there were many military and civil turbofan and turboshaft engines in the hands of the take-off department, which needed further theoretical verification on the high-altitude simulation test bench, especially the high-altitude data of the second generation, the second generation, the fifth generation and the third generation core aircraft, which was very important for the future development of China's take-off aero-engine.

However, many high-altitude situations could not be achieved before, so that the performance of many aircraft launch equipment in China's take-off was only on paper, so that many finalized models were put into actual use before problems and deficiencies were found, resulting in many air accidents. Therefore, to make up for this shortcoming is also a major task for China's take-off.

However, the "equipment-01" high altitude simulation test platform has only four high altitude simulation test chambers, namely, the No.1 chamber with a diameter of 2 meters, the two No.2 and No.3 chambers with a diameter of 3 meters, and the largest No.4 chamber with a diameter of 3.7 meters.

This number simply can not meet the test requirements of many domestic aero-engine models. We should know that the test time of an aero-engine on the high altitude platform is at least 2000 hours.

This is quite smooth. In case of any accident, 4000 to 5000 hours is also normal. In other words, if an aeroengine wants to be fully demonstrated and reach mature performance, it will take a year and a half on the high altitude platform alone.

If China's take-off has only one or two models, it will be enough. If we work hard and wait for a while, we will be able to rank. The key is that China's take-off's aero-engine has a full spectrum. One WD series alone will produce 12 sub models. If the "equipment-01" high altitude simulation test platform gives all the quota to China's take-off, other development units will not have to live, Because we can't wait until the 21st century for China to take off and finish the high altitude platform test.

But if we don't take off for China, wouldn't it be a waste to invest so many sub models in the early stage?

In addition, the "equipment-01" high altitude simulation test bed could not meet the simulation of the altitude above 20000 meters and the speed above Mach 2.5, which could not provide any help for the development of China's next generation aero-engine and ramjet turbofan in line with aviation power, With the help of the favorable opportunity of the newly built "equipment-01" high altitude simulation test bed in China, fully absorb the technical success and engineering experience, and invest a large amount of money to build a higher level high altitude test bed, so as to meet the increasing demand of China's takeoff test.

In this way, with the help of Zhuang Jianye, a huge high-altitude test-bed with an area of 782 Mu and a total power consumption of more than 435 MW sprang up deep in the southern foot of Qinling Mountains.

In order to express the largest scale project of China's take-off since its founding, the leader of China's take-off, self-reliance, aviation and aerospace double master, naming maniac, Jianye, Nb, Zhuang naturally could not miss such a good naming opportunity, so he gave a domineering and elegant name: zbdl!

As a result, I don't know whether the higher-level leaders are too simple minded, or whether the naming method of Zhuang Jianye is not obvious enough. After the newspaper was published, the higher-level functional departments transliterated zbdl as "headquarters building", so the "headquarters building" project came into being
