Chapter 329 Phantom Stealth Bomber

Chapter 3: The Phantom Stealth Bomber

B2 stealth strategic bomber!
Known as the most expensive aircraft in the world, one costs 24 billion U.S. dollars, and you can’t buy it even if you have money. The United States will not allow such a big killer to be sold. After all, it is the B2 stealth strategic bomber in service in the United States. There are less than 20.

Although the B2 stealth strategic bomber has been in service for more than ten years, nearly 20 years, but the American B2 strategic bomber has never participated in air shows, let alone air show performances, even in the United States, basically they will not be displayed.

As for the specific situation of the B2 stealth strategic bomber, even the national intelligence agencies know very little, almost the data released by the United States itself.

Qin Yuanqing looked at an airplane model in the meeting room. It was shaped like a big bat with a very large wingspan. The flying wing layout made it look weird, but it also gave it obvious advantages.

As before, he crossed the river directly touching Ying Jiang's head.

Therefore, the appearance of this stealth bomber code-named "Phantom" looks almost exactly the same as the B2 stealth strategic bomber. It is not an exaggeration to say that it is a twin.

"Dean, we have rigorously demonstrated such a layout, and it is theoretically feasible." Tang Bin, the deputy chief engineer of the 'Phantom' stealth bomber, said that Qin Yuanqing personally served as the chief engineer of the 'Phantom' stealth bomber, and then set up Among the seven deputy chief engineers, Tang Bin is the deputy chief engineer of the Aero-Engine Research Institute. He was just elected as an academician of the Academy of Engineering last year: "According to the layout of the flying wings, the bomb magazine of the bomber is located in the middle, between the two engine inlets, and the magazine It can be very large and can hang more than 20 tons of ammunition."

"Because our 'Phantom' strategic bomber is the benchmark B2 stealth strategic bomber, we put forward multiple indicators for its performance, such as stealth, supersonic speed, and large bomb load!" It has been proved that there is no problem with the current preliminary design plan, and it can be achieved after the technology is improved.”

"Our academy is mainly responsible for aero engines. After demonstration, only four large afterburning turbofan engines, each with a thrust of 10 tons, can fully realize the maximum take-off weight of the 'ghost' strategic bomber of 180 tons. It can achieve supersonic cruise at Mach 1.2, the service ceiling can reach 16000 meters, the maximum range is 1.2 kilometers, and it can reach 1.9 kilometers after refueling." Tang Bin said.

"Old Tang, when it comes to engines, you must be very careful, and demonstrate again and again to ensure that there is no problem." Qin Yuanqing said: "You also know that an aero engine is the heart of an aircraft, the source of power, and it determines the performance of the aircraft."

Qin Yuanqing is not optimistic. Although aero-engines have developed five types of aero-engines in the field of aero-engines, each of which is very advanced in performance and has received unanimous praise from the military, it must be known that the engines of strategic bombers are different. It is the thrust problem, it must ensure that the aircraft can reach Mach 1.2 supersonic flight, but also ensure good stealth performance.

The stealth performance lies not only in the paint with stealth performance, but also in the aerodynamic layout of the aero-engine.

"Dean, we are currently arranging supercomputer simulations for verification." Tang Bin said: "In terms of materials, Mr. Liu and his team have made another breakthrough, and the high temperature resistance has reached 2000°C."

Qin Yuanqing was a little surprised. He didn't expect to have a new breakthrough in materials. Although it's just an increase of 50~100°C, this is a remarkable achievement.

"It seems that another great achievement has been made in terms of materials. This year, the first prize of the Progress Award will be lost." Qin Yuanqing said with a smile.

Last year, with the Y-30 strategic transport aircraft, the aero engine won 8 national awards, which can be said to be fruitful.Looking at this year, it would not be said that there is no gain. At least the high temperature resistance of materials has increased by 50~10°C. At the awards conference, it was at least the first prize of the Progress Award.

"The entire research and development plan will be completed by September next year, and then the model will be manufactured for wind tunnel experiments, and the prototype of the engine will be manufactured and tested at the same time. It is planned to manufacture the prototype of the 'Phantom' stealth bomber and conduct its first test flight by 9," Tang Bin introduced. The current plan: "The power system, avionics system and other aspects are currently the most advanced in China, and a large number of alloy materials and composite materials are used. Even now, the application of graphene is being demonstrated. The entire research and development cost is expected to invest 2019 billion yuan, or about 200 billion U.S. dollars."

Qin Yuanqing nodded slightly, which means that from the preparation last year to the first test flight of the 'Phantom' stealth bomber, the development cycle will reach 4 years.

Four years seems to be much longer than the original Everest engine and Y-4 strategic transport aircraft, but the research and development of an aircraft is really very short.

Of course, like the B2 stealth bomber, it took more than [-] years from the confirmation of development to the first test flight. It is also because the United States did not allocate all the research and development costs at once, but listed a schedule for pre-development, otherwise it would not take so long.

The "Phantom" stealth strategic bomber is different. The development cost is listed at one time. The research institute does not have that much money, but Qin Yuanqing has it. He directly lends it to the research institute without interest, and will return it to him after obtaining the technology buyout fee in the future. that is.

So four years is neither too long nor too short, thanks to the technical accumulation of the Aero Engine Research Institute in the field of aero engines, many of the previous breakthroughs can be applied, plus thousands of R&D personnel are basically experienced.And other units have been tempered in J-10, J-20, Y-20 and other projects over the years, and the research institute is also willing to give money. Otherwise, such a scientific research project can be completed in 10 years. .

"Old Tang, please let me know that a meeting of deputy chief teachers will be held in the courtyard on July 7, and the other six deputy chief teachers will be invited to the courtyard." Qin Yuanqing said.

"Yes, Dean!" Tang Bin said.

Tang Bin was originally a full professor of the School of Aeronautics and Astronautics. Later, when the Institute of Aeronautical Engines was established, he joined the academy. Over the years, he has stood out with his excellent technical ability. , stand out among peers.

After all, to be elected as an academician, basically you have to be over 55 years old, or even 60 years old. Being able to be elected as an academician at the age of 60 is considered relatively young.Tang Bin was just 50 years old when he was elected as an academician.

Another elected academician is 'Hou Yong', who was 54 years old when he was elected as an academician, and was also appointed by Qin Yuanqing as the vice president of the Aero-Engine Research Institute.

If it weren't for Hou Yong's lack of qualifications, Qin Yuanqing would have liked to let him be the dean directly, and then Qin Yuanqing could get away from many meetings.

It’s just that sometimes you have to admit that qualifications do exist, and it takes a few years for an academician to enjoy it.Like now, if Hou Yong is allowed to connect with some units, those units may not be able to give face.

Then Qin Yuanqing took a look at the preliminary plan that was set now, and made slight adjustments to the aerodynamic layout to optimize the gas flow performance, and then made some structural adjustments to make the structure more reasonable and avoid waste.

Sometimes, although Qin Yuanqing does not rely on the system, he can often achieve better optimization by relying on his own ability and feeling.

And every researcher in the research institute is already accustomed to Qin Yuanqing's magic. In their minds, Qin Yuanqing is like a god, omnipotent and omnipotent.

"Jiayi, what's the matter?" Just as Qin Yuanqing was going to check on the situation of the Material Institute, he received a call from Xu Jiayi.

"Boss, can you come back, I have something to report to you!" Xu Jiayi whispered.

Qin Yuanqing was surprised. There was something that he couldn’t say on the phone. You must know that their phones were not purchased from the market, but were specially made and strictly inspected before they could be used. There was no problem with their safety. Worried about being monitored.

And it's already nine o'clock in the evening, and Xu Jiayi hasn't got off work yet?Isn't this girl always yelling, she should have a good rest and spend time with the child during this period of time?
Although he was curious, Qin Yuanqing still left the Aero Engine Research Institute and went to the Automobile Research Institute. He saw that the Automobile Research Institute was full of black lights, and none of the offices were lit.

Qin Yuanqing couldn't help muttering in his heart, what the hell is Xu Jiayi up to, he asked him to come over after get off work, isn't he just kidding himself?

Is she divorced?Want to seduce yourself?
But you are not that kind of person?

Qin Yuanqing entered his fingerprints, performed facial recognition, entered the gate, picked up his mobile phone and called Xu Jiayi, and at this moment, the light suddenly turned on, it was not a bright light, but a colored light, and then he saw Xu Jiayi's hand Holding a bouquet of flowers, Yang Jing walked over with a big cake in her hands, while the others held electronic candles in their hands.

"Boss, happy birthday! On behalf of everyone, thank you, thank you for guiding us forward!" Xu Jiayi said softly.

Then the cheerful birthday song sounded, and everyone sent their most sincere wishes to Qin Yuanqing.

A huge sense of happiness suddenly struck, and Qin Yuanqing couldn't help being moved so that the corners of his eyes became moist. These guys suddenly gave him such a big surprise.

Qin Yuanqing closed his eyes slightly, made a wish, and then blew out the 26 candles on the big cake at once, and there was warm applause and cheers immediately.

"Thank you everyone, thank you for this surprise, I am very happy to have you!" Qin Yuanqing said sincerely to everyone.

He himself forgot that today was his birthday, but these guys all remembered it.Then I gave myself such a big surprise.

Holding flowers in his hands and wearing a birthday hat on his head, Qin Yuanqing cut the cake by himself. The cake was very big. After Qin Yuanqing cut the first piece of cake, other people helped cut the cake one after another.

Qin Yuanqing rose up and invited everyone to hang out together, but Xu Jiayi and others drove Qin Yuanqing home one after another, making Qin Yuanqing laugh dumbfounded, and even asked him to help pack things, but they refused to let him go home early.
