Rebirth of science and technology academic master

XAC Group

Compared with the last time I came here, the area of ​​​​XAC Group has expanded a lot. Obviously, with the Y-20, Y-30, H-20, and 'Phantom' stealth strategic bombers settled in XAC Group, XAC Group has expanded its area. The Aircraft Group has to expand. After all, these aircraft are big, and the assembly plants are not comparable to ordinary assembly plants.

The steady flow of orders has given XAC enough confidence and financial resources to expand, whether it is the expansion of factories, the increase of production lines, or the increase of workers!

"Principal Qin, from the current point of view, the performance of the 'Phantom' stealth strategic bomber is very satisfactory in all aspects. XAC has finally completed the first prototype. The superiors have great expectations for the 'Phantom' stealth strategic bomber. Even during the test flight, the dean may personally participate." The CEO of AVIC Group said energetically.

Over the years, Huaxia has continued to make breakthroughs in aircraft. Naturally, the groups below have benefited a lot. However, as the superior, AVIC Group has also benefited a lot. It often receives awards from superiors. The previous leaders were directly transferred to local supervisors. One place.

And now, the 'Phantom' stealth strategic bomber is about to roll off the production line, followed by test flights. Although it may not be ready for service before the National Day, it is definitely a major political achievement and enough to make the leaders of AVIC happy.

"Speaking of which, President Qin, you are a great benefactor to our AVIC Group. With your promotion, our aviation field has achieved tremendous development and achievements." The AVIC leader said with a smile: "Perhaps our domestically produced large aircraft will be officially commercialized next year. , Chinese people can also use our own large aircraft, and don’t have to worry about being intimidated!”

AVIC is a behemoth with aviation equipment, transport aircraft, engines, helicopters, airborne equipment and systems, general aircraft, aviation research, flight testing, trade logistics, asset management, finance, engineering construction, automobiles and other industrial sectors. It has more than 140 member units, more than 30 listed companies, and more than 500,000 employees. Anyway, in China, whether it is building fighter jets, transport aircraft, helicopters, or military engines, they all belong to AVIC.

In the Shuimu University Aero Engine Research Institute, AVIC Group also holds 10% of the shares and is nominally managed by AVIC Group.

In recent years, China's aviation industry has advanced by leaps and bounds, making huge breakthroughs in both military and civilian aspects, among which Qin Yuanqing cannot be circumvented. Without Qin Yuanqing, such great achievements would never have been possible.

With the arrival of leaders from all parties, the first prototype of the 'Phantom' stealth strategic bomber officially rolled off the production line. After the red cloth was lowered, the 'Phantom' stealth strategic bomber was seen wearing a big red flower on its nose. In front of the behemoth of the 'Phantom' stealth strategic bomber, it looks particularly small.

When the leader gave a speech, he said happily: "Comrades have worked hard. In order for us to be able to equip the 'Phantom' stealth strategic bomber as soon as possible, I heard that the employees of XAC worked day and night, and finally in the near future The final assembly of the first 'Phantom' stealth strategic bomber prototype has been completed before. This is a very remarkable miracle. On behalf of the military, I would like to thank you for your efforts!"

The applause rang out enthusiastically, this was indeed a miracle!

After all, how long does it take from finalizing the 'Phantom' stealth strategic bomber to building the first 'Phantom' stealth strategic bomber prototype? You have to know that if it is in the United States, it will take at least three or four years, and three or four years. It's considered fast. Even if it takes five or six years to produce a prototype, that's normal.

Qin Yuanqing also expressed his sincere admiration for these dedicated and silent employees. He knows the Phantom stealth strategic bomber best and understands its technical content very well. It is conceivable that he can produce a prototype so quickly. We all know how hard all parties have worked just to let China have a stealth strategic bomber as a national artifact as soon as possible to protect China's security and safeguard China's sovereignty and interests.

The leader's speech was very inspiring.

When it was the turn of the leaders of AVIC to speak, the leaders of AVIC, as their immediate superiors, proudly said: "Thanks to the strong support from all parties for our aviation industry, we can produce the first prototype of the 'Phantom' stealth strategic bomber as scheduled. This It's a great joy. The Phantom stealth strategic bomber was developed entirely by ourselves. We master the core technology and its accessories are completely localized. Its performance is the most outstanding among the strategic bombers currently in service in the world. Yes, surpassing the American B2 stealth strategic bomber!"

"Next, we will speed up the test flight work, complete the test flight work as soon as possible, and put the 'Phantom' stealth strategic bomber into service!" AVIC leaders said firmly and forcefully.

Suddenly, warm applause roared.

Test flight, also known as flight test, as the name suggests, is the process of conducting scientific research and product testing under real conditions. The test objects are various aircraft, such as fighter jets, bombers, transport aircraft, helicopters, and special experimental research aircraft specially used for flight tests. The recording equipment and weapons and equipment on these aircraft are also test objects.

In the final analysis, aircraft must be put into practical use. No matter how good the design is before manufacturing, no matter how good the supercomputer simulation is, or how excellent the wind tunnel test is, in the final analysis, it will not be as clear as the actual application. What problems and problems need to be improved? You can get a clear understanding of it during the test flight, which will facilitate subsequent modifications and improvements.

The Aviation Industry Flight Test Center is my country’s only nationally authorized certification test agency.

No matter what kind of fighter, no matter what kind of helicopter, transport plane, or bomber, it must go through test flights and a series of appraisals before it can be determined whether it can serve.

Therefore, the duration of test flights can be short or long. In short, test flights such as J20B and Y-30 are extremely short. It is the outstanding performance and stability displayed during the test flight that enable superiors to judge that they can be directly put into mass production and service. . In the long run, just like the C919, the entire test flight phase lasts for several years. Some fighters even have many problems. It is normal for the test flight to last for 10 years.

Test flight is also a very dangerous thing. Whether it is the first flight or the entire test flight, the process of exploring the performance of the aircraft seems to be the same as ordinary flight, but in fact it is often accompanied by great risks. .

The world is a big place, and I want to go outside the line and see where the limits of airplanes are. This seemingly small step is often accompanied by great risks. If the speed is too low, the aircraft will be unable to control due to insufficient lift; if the acceleration is too high, the aircraft structure may be irreversibly damaged.

And every exploration close to the limit or even beyond the limit is accumulating strength for the pilot's survival and even victory in the future battlefield. Flight test is a systematic project that integrates science, engineering and risk.

The performance of an aircraft does not entirely depend on the design. After all, an aircraft is designed and manufactured. If the design is good, the manufacturing may not be perfect. Sometimes if the process fails, a certain performance may not meet the design requirements. Sometimes, during the manufacturing process, a certain screw is not tightened, which may lead to serious accidents.

All kinds of situations exist!

It’s not just overseas developed countries that have experienced air crashes during test flights, resulting in the heroic sacrifice of test pilots. Even in our country, it is not uncommon for test pilots to fly airplanes on test flights and become martyrs.

The grand roll-off ceremony of the first prototype allowed Qin Yuanqing to personally see the true face of the Phantom stealth strategic bomber. It was like a large bat, and full of science fiction colors, as if it existed in science fiction novels.

Qin Yuanqing even went so far as to personally board the Phantom stealth strategic bomber to see its interior. The spacious cabin was filled with lithium-air batteries that could not use space, the huge fuel tank, and the cockpit full of modern technology.

Behind these advanced technologies is a high cost. Even with the financial resources of the Aero Engine Research Institute, it can only cover the manufacturing cost of the first prototype, and cannot support the second one. It is also true that after this prototype aircraft will undergo a half-year test flight, the second prototype aircraft will not be produced until the Aero Engine Research Institute pays the second prepaid fee. It can be said that before the 70th National Day, the 'Phantom 'Stealth strategic bombers have no possibility of entering military service.

After all, various test flights to explore the performance of the Phantom stealth strategic bomber require a lot of time and multiple take-off experiments before it is possible to understand the performance of the aircraft.

"This aircraft looks very good and its performance is also very advanced. However, it has one disadvantage: it is expensive. It is so expensive that it makes my body hurt. For such a bomber, half of the aircraft carrier will be gone!" the leader said with a smile.

Even now, with the rapid improvement of China's economic strength, the military budget has been getting higher year by year in recent years. Now the annual military budget reaches 1.268 billion yuan, which is about 214 billion US dollars, which is only equivalent to about 1.2% of the total GDP. to 25% of U.S. military spending. The Chinese military needs to upgrade its equipment in all aspects, so although the military expenditure of 214 billion US dollars is a lot, it is actually not much. The military is eager to use one dollar as two dollars.

The construction of an aircraft carrier fleet costs money, the construction of submarines costs money, advanced rocket launchers cost money, advanced fighter jets cost money, and advanced transport aircraft cost money.

The more advanced the equipment, the more expensive it is. It is for this reason that the military continues to promote a frugal style, hoping to save more money to purchase one or two more pieces of advanced equipment.

And every year when the various military services allocate military expenditures, the big bosses from all parties are always quarrelsome, just wanting to get more funds for their own side and equip themselves with more advanced equipment.
