Rebirth of science and technology academic master

Chapter 330 Phantom Stealth Bomber

B2 stealth strategic bomber!

Known as the most expensive aircraft in the world, one costs 2.4 billion U.S. dollars, and you can’t even buy it if you have the money. The United States will not allow such a killer weapon to be sold. After all, it is the B2 stealth strategic bomber in service in the United States. There are less than 20 aircraft.

Although the B2 stealth strategic bomber has been in service for more than ten years, close to 20 years, the American B2 strategic bomber has never participated in air shows, let alone air show performances. Even in the United States, it is basically not displayed.

Regarding the specific situation of the B2 stealth strategic bomber, even the national intelligence agencies know very little about it, and it is almost the data released by the United States itself.

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

As before, just touch Yingjiang's head to cross the river.

Therefore, the appearance of this stealth bomber codenamed "Phantom" looks almost exactly the same as the B2 stealth strategic bomber. It is not an exaggeration to say that they are twins.

"Dean, we have rigorously demonstrated this layout, and it is theoretically feasible." Tang Bin, deputy chief engineer of the Phantom stealth bomber, said. Qin Yuanqing personally served as the chief engineer of this Phantom stealth bomber, and then set up a Among the seven deputy chief engineers, Tang Bin is the own 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 wing, the bomber's magazine is located in the middle, between the two engine inlets, and the magazine It can be very large and can hold more than twenty tons of ammunition.”

"Because our 'Phantom' strategic bomber is the benchmark B2 stealth strategic bomber, we have put forward many indicators for its performance such as stealth, supersonic speed, and large bomb load!" Tang Bin introduced: "After rigorous testing by various units, Demonstration, there is no problem with the current preliminary design plan, and it can be achieved after the technology is improved."

"Our institute is mainly responsible for aviation engines. After demonstration, we only need four large afterburning turbofan engines, each with a thrust of 10 tons, to fully realize the maximum take-off weight of the 'Phantom' strategic bomber of 180 tons. It can achieve supersonic cruise at Mach 1.2, with a practical ceiling of up to 16,000 meters, a maximum range of 12,000 kilometers, and can reach 19,000 kilometers after refueling," Tang Bin said.

"Old Tang, when it comes to engines, we must be very cautious and make repeated arguments to ensure that there are no problems." Qin Yuanqing said: "You also know that the aeroengine is the heart and source of power of an aircraft. It determines the performance of the aircraft."

Qin Yuanqing is not optimistic. Although five engines have been developed in the field of aviation engines so far, each of which has very advanced performance and has been highly praised by the military. However, you must know that the engines of strategic bombers are different, not only It is a matter of thrust, which must not only ensure that the aircraft can reach supersonic flight of Mach 1.2, but also ensure good stealth performance.

Stealth performance lies not only in the coating with stealth performance, but also in the aerodynamic layout of the aircraft 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, with high temperature resistance reaching 2000°C."

Qin Yuanqing was a little surprised. He did not expect that there would be a new breakthrough in materials. Even though it was only an increase of 50 to 100 degrees Celsius, this was an incredible achievement.

"It seems that another incredible achievement has been made in the materials field. This year, the first prize for the Progress Award cannot be won." Qin Yuanqing said with a smile.

Last year, with the Y-30 strategic transport aircraft, the aviation engine won 8 national awards, which can be said to be fruitful. This year, it would not be said that there is no gain. At least the high temperature resistance of the materials has increased by 50~10℃. At the award conference, at least there will be a first prize for progress.

"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 engine prototype will be manufactured and tested at the same time. It is planned to manufacture a prototype of the 'Phantom' stealth bomber and conduct its first test flight by 2019." Tang Bin introduced Current plan: "The power system, avionics system, etc. are all currently the most advanced in China. A large number of alloy materials and composite materials are used, and the application of graphene is even being demonstrated. The entire R\u0026D cost is expected to be 20 billion. Yuan, equivalent to approximately 3.4 billion U.S. dollars.”

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

Four years seems to be much longer than the original Everest engine and Y-30 strategic transport aircraft, but the development of an aircraft is actually very short.

Of course, it took more than 20 years for the B2 stealth bomber to go from final development to first test flight. This is also because the United States did not allocate all research and development expenses at once, but set a timetable for pre-development. Otherwise, it would not have taken that long.

The 'Phantom' stealth strategic bomber is different. The development cost is a one-time payment. The institute does not have that much money, but Qin Yuanqing does. He directly lends it to the institute without interest and will pay it back to him after receiving the technology buyout fee in the future. that is.

Therefore, four years is neither long nor short. Thanks to the technological accumulation of the Aero Engine Research Institute in the field of aero engines, many breakthroughs made before can be applied. In addition, thousands of R\u0026D personnel are basically experienced. Other units have been trained in J-10, J-20, Y-20 and other projects over the years, and the research institute is also very willing to pay. Otherwise, such a scientific research project can be completed in 10 years, which is considered good. .

"Old Tang, please inform me that a deputy chief engineer meeting will be held in the courtyard on July 5th, and the other six deputy chief engineers will be invited to the courtyard." Qin Yuanqing said.

"Yes, Dean!" Tang Bin said.

Tang Bin was originally a full professor at the School of Aeronautics and Astronautics. Later, he joined the Aerospace Engine Research Institute when it was established. Over the years, he stood out with his excellent technical ability. The year before last, he was named a candidate for the Academy of Engineering by Qin Yuanqing. Last year, he was elected as an academician of the Academy of Engineering. , stands out among his peers.

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

Another academician was elected as ‘Hou Yong’, who was 54 years old when he was elected. He was also appointed by Qin Yuanqing as the vice president of the Aerospace Engine Research Institute.

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

But sometimes you have to admit that qualifications do exist, and it takes several years for an academician to be successful. Like now, if Hou Yong is asked to connect with some units, those units may not be able to give him face.

Qin Yuanqing then took a look at the preliminary plan and made slight adjustments to the aerodynamic layout to optimize the gas flow performance. Then he 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 abilities and feelings.

Every researcher at the institute has become accustomed to Qin Yuanqing's magic. In their minds, Qin Yuanqing is like a god, omnipotent and omnipotent.

"Jiayi, what's wrong?" Just when Qin Yuanqing was going to check on the situation at the Materials Institute, he received a call from Xu Jiayi.

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

Qin Yuanqing was surprised. Is there anything that cannot be said on the phone? You must know that their phones are not bought in the market, but are specially made and strictly inspected before they can be used. There is no problem with safety at all, so there is no need to use them. Worry about being monitored.

And it's already nine o'clock in the evening, Xu Jiayi hasn't gotten off work yet? Isn't this girl always shouting that she should have a good rest and spend time with her children during this time?

Although he was curious, Qin Yuanqing left the Aero Engine Research Institute and went to the Automobile Research Institute. He saw that the Automobile Research Institute was dark and not a single office was lit.

Qin Yuanqing couldn't help but murmur in his heart, what the hell was Xu Jiayi doing? She asked him to come over after get off work. Wasn't he kidding himself?

Is she divorced? Want to seduce yourself?

But you are not that kind of person?

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

"Happy birthday, boss! I thank you on behalf of everyone, thank you for guiding us forward!" Xu Jiayi said softly.

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

A huge sense of happiness suddenly came over, which made Qin Yuanqing so moved 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. Warm applause and cheers immediately broke out.

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

He even forgot that today was his birthday, but these guys 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 himself. The cake was very big. After Qin Yuanqing cut the first piece of cake, others helped cut the cake.

Qin Yuanqing got up and invited everyone to go out to play, but Xu Jiayi and others sent Qin Yuanqing home one after another, making Qin Yuanqing laugh. Even if he wanted to help pack things, they refused to let him go home early.
