Rebirth of science and technology academic master

Chapter 247 Large-scale scientific research projects

A rare seven-day holiday during National Day!

Just after the seven-day National Day holiday, Qin Yuanqing received an invitation from his superiors to visit a large-scale scientific research project in China. As for the specifics, he did not go into details, and Qin Yuanqing did not ask. At this level, when it comes to large-scale scientific research projects, Qin Yuanqing already knows that they involve a high level of confidentiality.

After receiving the call, Qin Yuanqing was very strange.

After all, he is not in the system, and he should not be invited to these things. For example, the Everest aircraft engine was developed by him because he led the development.

In the afternoon, a man in military uniform drove a military vehicle to pick him up. After the institute confirmed his identity in detail, Qin Yuanqing got in the car. Only when he arrived at the Air Force Airport did Qin Yuanqing see the expert group. Some of them were known to Qin Yuanqing, and others Qin Yuanqing didn't recognize some of them.

This time we were on a military plane, so you can imagine how high the level of confidentiality was.

The team was led by a leader of the Navy. In addition to experts, there were also leaders of several departments, including the Science and Technology Commission, the General Staff, etc., all of whom were very high-level.

On the military plane, everyone got this information. Qin Yuanqing only found out after looking at the information that this so-called large-scale scientific research project was a domestic aircraft carrier project.

Last year, the 001 aircraft carrier was officially delivered to the Navy, and then the construction of its own domestic aircraft carrier was started. After all, the 001 aircraft carrier originated from the Soviet Union. No matter how the hull is modified, it is still there. The 001 aircraft carrier is actually a transitional aircraft carrier. Its biggest purpose is Conduct drills, explore the use of aircraft carriers, and imitate an entire aircraft carrier construction technology.

And this 002 aircraft carrier is the truly domestic aircraft carrier, which was built by China from scratch. According to the data, this 002 aircraft carrier is similar to the 001 aircraft carrier, about 315 meters long, about 75 meters wide, with a displacement of 55,000 tons and a full load displacement of 67,000 tons. The power system is powered by 4 steam turbines, with 4 shafts, 4 propellers and twin rudders for propulsion. It has a total power of 200,000 horsepower, a maximum speed of up to 32 knots, an endurance of 4,000 nautical miles at a speed of 30 knots, and an endurance of 12,000 nautical miles at a speed of 20 knots. . . . .

From a design point of view, the 002 aircraft carrier is modified and upgraded based on the 001 aircraft carrier. It has increased the hangar capacity and can carry at least 36 carrier-based aircraft, which is a 50% increase compared to the 001 aircraft carrier.

After Qin Yuanqing read the information, the plane landed, and a military vehicle came to pick him up. He arrived at the scientific research base in just ten minutes.

They plan to stay at the scientific research base for half a month, visit the scientific research base, and serve as a think tank to help solve their respective professional matters.

They were also greeted by a luxurious lineup, and the chief engineer said enthusiastically: "Experts are welcome to come and help us solve our problems!"

Then he took everyone to the guest house and held a small reception banquet. The food for the banquet was very rich, including all kinds of seafood.

"Academician Qin, it is better to meet than to be famous! Your name is like thunder!" A middle-aged man in a white military uniform chatted with Qin Yuanqing enthusiastically: "I am Ma Weiming, and we are alumni!"

"Brother Ma, I've heard of you for a long time. You are also a famous person in our Shuimu!" ​​Qin Yuanqing also said politely.

Ma Weiming is an expert in power and electrical engineering, an academician of the Academy of Engineering, a professor and doctoral supervisor at the Naval Engineering University, and the director of the National Defense Science and Technology Key Laboratory of Ship Integrated Power Technology at the Naval Engineering University. He has long been committed to independent system integrated power generation and electromagnetic compatibility of independent power systems. Teaching and research in the fields of , power electronics application technology and other fields, he is the top scientist in the country in this regard. He studied and received a doctorate in electrical engineering from 1993 to 1996 in Shuimu. In 1996, he was named a national young and middle-aged expert with outstanding contributions. In 1999, he won the national top ten "Outstanding Professional and Technical Talents" medal and the Ho Leung Ho Lee Science and Technology Award. . In 2001, Ma Weiming was elected as an academician of the Academy of Engineering at the age of 41. He is one of the few people who can be elected as an academician at a very young age.

"I was so happy to know that you were on the expert team this time that I didn't sleep all night last night, thinking that you could help our team!" Ma Weiming and Qin Yuanqing clinked their wine glasses, took a sip of juice, and said.

"Do you need my help with any questions?" Qin Yuanqing was a little confused: "I'm a theoretical person, I don't know much about technology and application issues."

What impressed Qin Yuanqing the most about Ma Weiming was that in his previous life, he was known as the man who caused the most "war neglect" headaches. Many people even lamented: "Sorrow for his misfortune, anger for his inability to fight." China's century-old achievements were destroyed by Ma Weiming , the lifelong enemy of Bureau!

In Qin Yuanqing's view, Ma Weiming is the top scientist in the field. If he can't solve the problem, Qin Yuanqing probably won't be able to solve it either, unless he cheats!

"Don't say that, you are recognized as a top algorithm master, computer expert, power expert, materials expert, structural expert..." Ma Weiming said quickly. Although Qin Yuanqing is not half his age, he has been in the car since After showing off his skills in the fields of aviation and aerospace engines, Qin Yuanqing already has several labels on his head.

Then several scientific researchers came over to communicate with Qin Yuanqing. They all said good things, hoping that Qin Yuanqing could solve some problems for them or provide them with ideas to solve the problem.

The aircraft carrier is a huge system, backed by a powerful country. After all, modern aircraft carriers and the aircraft carriers during World War II are two different things and cannot be compared. Just like Markov, the director of the Black Sea Shipyard, was asked what the factory would need if the aircraft carrier was to be completed. Markov’s classic answer was: “The Soviet Union, the Party Central Committee, the State Planning Commission, the Military Industrial Committee and the nine defense industries Department, 600 related majors, and 8,000 supporting manufacturers. In short, it takes a great country to complete it."

The number of construction supporting units for the domestically produced 002 aircraft carrier has also reached 532. It is strongly integrated by various departments at the higher level and integrates a large number of experts. The peak number of employees is planned to reach 5,000.

An aircraft carrier involves more than 600 majors. It is no exaggeration to be hailed as a symbol of comprehensive national strength.

Although China has modified the 001 aircraft carrier and explored a complete set of aircraft carrier technologies, it is still in the imitation stage after all, and there are always some things that are not satisfactory. For example, because it has not conquered the steam ejection technology, the 002 aircraft carrier still uses a ski jump to take off. In terms of power, conventional power is still used instead of nuclear power because the technology is not yet mature.

It can be said that although the 002 aircraft carrier has begun to be built, there are still many technical difficulties to be solved. It is also destined that the 002 aircraft carrier is used for training rather than China's final ship. There will definitely be a 003 aircraft carrier.

In the afternoon, other experts were still resting. After all, many experts were no longer young. However, Qin Yuanqing was dragged to their team by Ma Weiming. As he walked, he said: "Our team is engaged in power engineering and is responsible for ejection from the aircraft carrier." This is the content of the device.”

"Electromagnetic ejection?" Qin Yuanqing asked curiously.

"Yes, you know that too?"

Qin Yuanqing smiled and said: "I am also a fan of the puppet army! How is your progress? Can it be installed on the aircraft carrier?"

Ma Weiming shook his head and said: "The current ship is definitely hopeless. Electromagnetic power ejection still has many problems to deal with!"

Electromagnetic ejection, with electromagnetic force as the driving force source, is one of the most cutting-edge military technologies in the electromagnetic field. It is on par with, or even slightly surpasses, all-electric comprehensive propulsion technology. It is the truly top core technology in the aircraft carrier field of human civilization today. It has always had the word label of 'advanced' and 'cutting-edge'.

At present, the entire technology of electromagnetic catapult is extremely difficult to develop. Only the USS Ford aircraft carrier of the US Navy in the world uses electromagnetic catapult technology.

As a rabbit who has been studying the United States and crossing the river by feeling the eagle sauce, how could he not develop electromagnetic ejection.

It's just that as a latecomer, with a relatively late start and relatively little money, China is still a long way from being mature in the field of electronic ejection.

Qin Yuanqing once watched a video made by the Bureau, which introduced steam ejection and electromagnetic ejection. Electromagnetic ejection quickly and continuously allows aircraft to take off, which greatly enhances the combat effectiveness of the aircraft carrier. It is a pity that until the moment Qin Yuanqing was reborn, China's electromagnetic catapult is not used on aircraft carriers.

Of course, it was rumored at that time that the 003 aircraft carrier used electromagnetic ejection, but there was no official confirmation.

Qin Yuanqing came to Ma Weiming's design team. Ma Weiming introduced Qin Yuanqing. Because he wanted Qin Yuanqing's help, Ma Weiming introduced it in detail.

Their team not only deals with catapult issues, but also includes independent system integrated power generation, power electronics, and electromagnetic compatibility of power systems.

Qin Yuanqing was keenly aware of the anomalies in the data, and then put forward some suggestions of his own. At the same time, Qin Yuanqing personally optimized the data architecture.

Ma Weiming was very happy, and at the same time he felt incredible. Is this the world's top mathematician? His computing power is so terrifying.

You must know that aircraft carriers, as a large-scale scientific research project, can naturally use supercomputers. They were all calculated by supercomputers and there were no problems. As a result, Qin Yuanqing selected 10 problems in less than a day and was able to make suggestions for modifications. As for the software, they cooperated with top computers. As a result, Qin Yuanqing optimized the software. After optimization, the software only remained 20% of its original size, but its performance increased by 30%.

As Qin Yuanqing continued to understand more deeply, he vaguely understood that from the perspective of the aircraft carrier system, it is actually equivalent to a computer. Software and hardware are both very important. If the hardware is advanced, the software cannot function, and if the hardware is backward, the software cannot function if it is advanced. Enough fighting power.

The operating system of the aircraft carrier actually uses a very backward operating system. This shows that those computer institutes in China are really not good at operating systems. Qin Yuanqing was involved in the aircraft carrier's operating system when solving the software system of Ma Weiming and his team.
