Chapter 1363 The toys of a great country

Previous page        Return to Catalog        Next page

    Hearing what the head of the headquarters said, many military leaders and chiefs were still a little confused. What is an aero-engine high-altitude test bed?  Is this thing important?  How could the head of the headquarters be so excited?

    As a result, before these unit leaders and chiefs could raise questions, the head of the headquarters had already reported to the military leaders beside him: "The China Ascendas project was started five years ago. It was invested by Ascendas, located at the southern foot of Qinling Mountains.  Party and the Aviation Industry Corporation jointly funded the establishment. After the southeast coastal incident in 1996, in response to the superiors¡¯ initiative to strengthen the construction of basic scientific research, the headquarters also invested 800 million yuan to participate"

    Hearing this, the military leader suddenly realized: "OhI 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 exceeds 3 billion yuan, of which Ascendas Investment will bear 32%, the headquarters will bear 26%, the local government will bear 26%, and the Aviation Industry Corporation will bear 16%  , it was originally expected to be completed in 8 years, but I didn¡¯t expect it to be completed in only 5 years¡±

    The head of the headquarters sighed with emotion: "No wonder these China Takeoffs are so confident in showing off their wd-64vip aero engines. With the support of the 'Headquarters Building' project, the originally time-consuming and labor-intensive test flight verification has been completed on the ground."  It can be easily accomplished. After all, as the world's second largest aero-engine high-altitude test bed, the 'Headquarters Building' project has two high-altitude simulation experimental cabins with a diameter of 6.5 meters, which can simulate an altitude of 30,000 meters, a speed of Mach 3.8, and a net air flow rate.  It is the operating state of an aeroengine in an environment of 1158 kilograms per second Its technical level is second only to the 8.7-meter-diameter astf high-altitude test simulation platform built by NASA, Boeing and Lockheed Martin in the late 1980s"

    Hearing this, the military leader thought it was okay. After all, he was the one who approved the entire "Headquarters Building" project. But it was different for others present, because many of them had heard of the existence of this project for the first time.  In addition, the head of the headquarters did not speak loudly, but it was just enough to be heard by the heads of troops and leaders present, which further confirmed that the head of the headquarters was using the report to introduce the "headquarters" to them, the head of the troops and leaders.  Building" project, naturally listened more carefully.

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

    After all, many people present are very knowledgeable. For example, the previous leader of the Air Force who knew a lot about aero engines, and the leader of the Naval Aviation, knew the value of this high-level aero engine high-altitude test bed.

    ¡°To sum it up in one sentence, if you want to develop mature aero engines, high-altitude test benches are the absolute standard.

    Otherwise, almost all countries or companies that threaten to develop aero engines are just rogues!

    Because the high-altitude test bed is equivalent to the movie enlightenment of the island nation's love mentor before the macho man and the beauty race, compared to the aerospace engine, they are absolutely complementary and indispensable.

    The reason for this is that there is no way. With the improvement of aviation technology, the flying height and flying speed of aircraft are also rising.

    The situation at medium and low altitudes is pretty good. An ordinary test bench can simulate normal pressure, wind and speed. The environment above an altitude of 10,000 meters is completely different. Under such circumstances, how should the engine's air intake speed be controlled?  ?  What is the impact of air pressure on engine surge?  How to maintain the efficiency of the engine at supersonic speed?

    These things require a high-altitude test simulation platform to make them.

    Of course, some experts say that it is also possible to use a test aircraft.

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

    An ordinary fighter?

    The speed and height can be achieved, but the aircraft platform is too small to accommodate so many testing instruments and equipment.

    Large bombers and transport aircraft can now carry large instruments and equipment. The problem is that they can only fly at Mach 0.85, which makes them unable to complete high-altitude and high-speed test flights.

    What's more, after all, test flights are very risky. If something goes wrong and a plane crashes, it will not only cause loss of personnel and property, but more importantly, it will be a blow to the entire morale and progress.

    Of course, the most important thing is the cost. It takes nearly 500,000 hours to test an aero engine from its parts. The whole machine test takes at least 120,000 hours, of which 10,000 hours are needed for commissioning tests.  If all these 10,000 hours were used for aircraft test flights, the cost would be so high that it would be crushing.

    That¡¯s all. The key point is that the efficiency of test flights with airplanes can also drive people crazy. After all, there will always be bad weather with wind, frost, rain and snow throughout the year. In order to ensure safety, flight tests can only be suspended. If it happens againCoupled with unfavorable factors such as the aircraft's mechanical failure and personnel's rotation gaps, it may take seven or eight years to figure out the results after 10,000 hours of test flight testing.

    Therefore, whether in terms of economic cost, efficiency, or safety, the high-altitude test simulation platform is an indispensable and important support in the development of aeroengines.

    But precisely because of this, the threshold for a high-altitude simulation test bed is extremely high. After repeated visits to the entire earth, only the five gangsters on the Security Council are equipped with this thing. In other words, only these five gangsters are theoretically capable of developing and producing it.  High performance aero engine capabilities.

    As for Germany, Japan, India, Brazil and other secondary powers who keep saying that they want to enter the aero-engine industry, the five gangsters just smile and watch the jokes of these secondary powers.

    You don¡¯t even have a high-altitude test simulation platform, but you still want to develop a high-performance aero engine?  Not to mention anything else, when the aircraft is traveling at Mach 1.5 per hour, how should the mechanism in the inlet change to ensure that the high-speed injected airflow does not damage the turbine fan blades, but also efficiently ensures the normal operation of the aeroengine without danger?  The surge?

    Using supercomputers for calculations?  Come on, even if you have a supercomputer, you still need relevant basic data to support it. How do you come up with these basic data?  Of course it is done bit by bit using a high-altitude simulation test bench, otherwise?

    And this Mach 1.5 airflow disturbance test is still the most entry-level small experiment among all high-altitude tests. As for the test of the working conditions of the turbofan-ramjet engine at an altitude of 30 kilometers and at a speed of Mach 3.5, that will only happen in the next twenty years.  The commanding heights in the aerospace industry.

    Therefore, it is useless no matter how officials and media in Germany, Japan, India, Brazil and other countries clamor for breakthroughs in their own aviation engines. The key is to see whether there are key supporting facilities. If not, even if they are strong men, they just don¡¯t understand anything.  The first brother can only be teased by beautiful women instead of taking the initiative to conquer.

    The problem is that Germany, Japan, India, and Brazil also want high-altitude test bench simulation benches, but this thing is really not something you can get if you want it, because the high-altitude simulation test bench not only requires a lot of investment, but also has extremely high technical requirements.  It is also a typical high energy consumption, which is simply not something that ordinary countries can afford. Because of this, the high-altitude simulation test bed is also called a toy of big countries!
