Take Off My Aviation Era

Genius remembers this site address in one second: [] The fastest update! No ads! Hearing what the head of the headquarters said, many army leaders and heads were still a little at a loss. What is an aero-engine high-altitude test bed? Is this important? How could the head of the headquarters become so excited?

As a result, before the leaders and leaders of these troops raised questions, the head of the headquarters had already reported to the military leaders beside him: "The project of China Ascendas started five years ago. It was invested by Ascendas and is located at the southern foot of the Qinling Mountains. Fang and the Aviation Industry Corporation jointly funded the establishment. After the southeast coastal incident in the year, in response to the higher-level initiative to strengthen the construction of basic scientific research, the headquarters also invested 100 million yuan to participate in it..."

Hearing this, the military leader suddenly said: "Oh...I remember, you are talking about the ‘headquarters building’ project, right?"

The head of the headquarters nodded: "Yes, it is the'headquarters building' project. The total investment of the entire project is more than 100 million yuan, of which Ascendas Investment will bear %, headquarters will bear %, local governments will bear %, and Aviation Industry Corporation will bear %. Completed, I didn’t expect it to be completed in less than a year..."

Speaking of the head of the headquarters, he sighed with emotion: "No wonder these Chinese take off so confidently displaying their -p aero engine. With the support of the'headquarters building' project, the original time-consuming and labor-intensive test flight verification can be done on the ground. Easy to complete. After all, as the world’s second largest aero-engine high-altitude test bed, the'headquarters building' project has two high-altitude simulation test cabins with a diameter of .m, which can simulate the altitude of meters, with a speed of .mach, and a net air flow of kilograms. The operating state of the aero engine in the second environment... Its technical level is second only to the high-altitude test simulation platform built by NASA, Boeing and Lockheed Martin in the late 1980s with a diameter of .m..."

Hearing this, the military leaders were nothing. After all, he approved the entire "headquarters building" project, but the others present were different, because many people had heard of the existence of this project for the first time. In addition, the voice of the head of the headquarters was not very loud, but it happened to be able to be heard by the leaders and leaders of the troops present. It also confirmed the head of the headquarters. This is to introduce them to the heads and leaders of the troops. Naturally, I listened more carefully to the "Building" project.

But because of this, many people were shocked by the advanced nature of this project.

After all, many people at the scene are still very knowledgeable. For example, the leader of the Air Force who knows a lot about aero engines, and the leader of the naval aviation force, are very clear about the value of this high-level aero-engine high-altitude test bed.

To sum it up in one sentence, if you want to develop a mature aero engine, the high-altitude test bench is the absolute standard.

Otherwise, almost all countries or companies that threaten to develop aeroengines are gangsters!

Because the high-altitude test bed is equivalent to the small film enlightenment of the island country love mentor of the macho and the beautiful woman before the drag racing, and it is absolutely complementary and indispensable.

The reason for this is that there is no alternative. With the improvement of aviation technology, the flight altitude and speed of aircraft are also rising.

The situation at low and medium altitudes is not bad. Normal pressure, wind and speed can be simulated with ordinary test benches. The environment above 10,000 meters is completely different. In this case, how should the intake speed of the engine be controlled? ? How much does air pressure affect the surge of the engine? How to maintain the efficiency of the engine under supersonic speed?

These things need high-altitude test simulation platform to make it.

Of course, there is an ironclad saying that the same can be done with a test flight.

The question is what kind of flight test aircraft is needed to complete such a complicated high-altitude and high-speed flight test?

Ordinary fighter?

The speed and height can be achieved, but the carrier platform is too small to hold so many test equipment.

Large bombers and transport aircraft can carry large-scale instruments and equipment. The problem is that only the speed of Mach can not complete the high-altitude and high-speed test flight missions.

What's more, there is a big risk in the test flight after all. If something goes wrong and the plane is destroyed or killed, it will not only lose personnel and property, but more importantly, it will be a blow to the overall morale and progress.

Of course, the most important thing is the cost. It takes nearly 10,000 hours to start the test of an aero engine from its parts, and the whole machine test takes 10,000 hours. Among them, the test run requires 10,000 hours. If all the flight tests are carried out in an hour, the cost can be extremely high.

That's all, the key is that the efficiency of flight test with aircraft will make people crazy. After all, there will always be bad weather of wind, frost, rain and snow during the year. In order to ensure safety, the flight test can only be suspended. Unfavorable factors such as mechanical failures, personnel's shifts, and so on, the 10,000-hour flight test said it would not take seven or eight years to figure it out.

Therefore, whether it is from economic cost, efficiency, or safety, the high-altitude test simulation platform is an indispensable and important basis for the development of aeroengines.

But also because of this, the threshold of the high-altitude simulation test bed is extremely high. Counting the entire earth, only the five gangsters of the Security Council are equipped with this thing. In other words, only these five gangsters are theoretically capable of development and production. The capabilities of high-performance aeroengines.

As for Germany, Japan, India, Brazil and other second-tier powers who keep saying that they want to enter into aero engines, the five big currents are just a smile, and each one is holding their arms to see how these second-tier powers make jokes.

You don't even have a high-altitude test simulation platform, and want to develop a high-performance aeroengine? Don’t say anything else~www.readwn.com~ When the aircraft is at Mach per hour, how should the mechanism in the air intake be changed to ensure that the high-speed jet does not damage the turbofan blades, but also efficiently guarantees the aero engine Work normally without dangerous surge?

Do calculations with supercomputers? Come on, even if you have a supercomputer, you have to have relevant basic data as support to calculate it. How do these basic data come from? Of course it is done a little bit with a high-altitude simulation test bench, otherwise?

And this Mach airflow disturbance test is still the most entry-level small experiment among all high-altitude tests. As for the kilometer altitude, at the Mach speed, the turbofan-ramjet working condition test will be the next two decades. The commanding heights of the field.

Therefore, it is useless for the official and media in Germany, Japan, India, Brazil and other countries to clamor for breakthroughs in their own aero engines. The key is to see whether there is a key supporting package. If not, even if it is a macho, it just doesn’t understand anything. The first brother of, can only be played by beautiful women instead of actively conquering.

The problem is that Germany, Japan, India, and Brazil also want high-altitude test benches, but this is not something that you can get if you want, because the high-altitude simulation test benches not only require a large investment, but also have extremely high technical requirements. It is also a typical high energy consumption, which is simply not something the average country can afford. Because of this, the high-altitude simulation test bench is also known as the toy of the big country!
