Chapter 913 Pulsating Assembly Line

Hotel banquet hall.

Thousands of mathematicians gathered here.

This was a celebration reception organized by Southwest Associated University.

Liu Tao had a smile on his face, holding a wine glass in his hand, and communicating with mathematicians one by one.

Liu Tao knew some of the domestic mathematicians, but he didn't know most of them.

For example, Liu Tao knew all the academicians, and he also basically knew the outstanding young people of the country. As for the others, Liu Tao only knew some of them.

Liu Tao basically didn't know any overseas mathematicians.

The only one he was slightly familiar with was Witten.

It was not Witten's identity as a mathematician, but Witten's identity as a physicist.

Other mathematicians took the initiative to greet and communicate with Liu Tao.

Liu Tao's achievement of proving Fermat's conjecture alone was great enough to completely establish Liu Tao's identity and status as the world's top mathematician.

Fermat's Last Theorem is a monument in the history of mathematics.

Some people say that the process of proving Fermat's Last Theorem is a history of mathematics. Because in the past 350 years, many mathematicians have made their own important achievements in order to prove Fermat's Last Theorem.

Euler expanded the application of imaginary numbers, Kummer founded the theory of ideal numbers, Faltings proved the Model conjecture, and Ken Betley proved the Frye proposition.

Fermat's Last Theorem gave birth to so many new ideas and new achievements. Hilbert compared Fermat's Last Theorem to "a goose that lays golden eggs", which is true.

Each branch of mathematics was once considered to be an isolated island, which developed independently on its own island. For example, elliptic curves and modular forms belong to different mathematical islands. In 1967, Robert Langlands speculated that many branches of mathematics are closely related. This speculation later evolved into the Langlands Program, which is considered to be the "grand unified theory" of mathematics.

Liu Tao established a solid bridge connecting the two isolated mathematical islands of elliptic curves and modular forms in proving Fermat's conjecture. Many modern mathematical achievements were perfectly integrated in it, adding a strong stroke to the concept of the grand unification of mathematics predicted by the Langlands Program, making the prospect of the grand unification of mathematics more visible.

A few days later, Liu Tao arrived at the 011 Aviation Base.

He came to an aircraft engine factory, which specializes in the production of "Ray Sculpture" helicopter aircraft engines.

In the normal assembly of aircraft engines, after the assembly of large components such as compressors and turbines, the bench is turned to a horizontal position, and then to the next station to install external pipelines, additional casings and other components, which is very complicated.

If the production quantity is large, the production capacity will be greatly affected.

So the pulsating assembly production line is used here.

The use of the pulsating assembly production line has shortened the assembly cycle by more than one third.

The pulsating assembly production line is not unfamiliar to Panshan Group. The diesel engines for tanks and armored vehicles were produced using the pulsating assembly production line.

Now, pulsating assembly lines are also being used for aircraft engines and aircraft.

For example, the J-10 and J-11 fighters are produced using pulsating assembly lines, and the annual output of one production line can reach 25.

This output is already very high.

With only four pulsating assembly lines, the annual output of the J-10 or J-11 fighters can reach 100.

Panshan Group has a huge demand for aircraft engines. It needs various types of aircraft engines for the J-7 and J-8. The demand for aircraft engines for the J-7 advanced trainer, J-7A advanced trainer, and Eagle advanced trainer is very large, not to mention the demand for engines for the J-10 and J-11 fighters.

There is also a huge demand for engines for the ‘Ray Eagle’ helicopter.

Without the pulsating assembly line, it is impossible to meet the needs of Panshan Group.

Besides, the aircraft engines produced by Panshan Group are not only used for the production and manufacturing of its own aircraft, but also provided to other units.

Panshan Group has such aviation engine factories not only in 011 Aviation Base, but also in other places.

After all, this is considered from the perspective of safety. It is necessary to ensure that even if the entire 011 Aviation Base is devastated, aviation engines and aircraft can be produced in other places.

This is the bottom line thinking.

Although this will not achieve the ideal production efficiency, it is necessary for safety.

All major countries in the world do this.

The same reason is that Panshan Group has set up aircraft production lines in other places instead of concentrating all aircraft production lines in 011 Aviation Base.

This ensures that unless the enemy is sure to destroy all the factories 100%, if some factories are destroyed, aircraft can still be produced continuously for the troops to use.

After inspecting this aviation engine factory, Liu Tao went to another aviation engine factory for inspection. This is a factory that specializes in producing different aviation engines required by the J-7 series. The aviation engines for the J-7 series have been replaced with the latest ones, which can have more powerful aviation engines, making the aircraft have stronger speed and stronger maneuverability.

The self-use version of the aircraft engine is different from the export version of the aircraft engine. The difference is not only reflected in the service life of the aircraft engine, but also in the performance. The export version of the aircraft engine is about 70% of the self-use version of the aircraft engine.

The scale of the engine required for the J-7 modification is the largest, not only because the latest J-7 modification needs an engine, but also because the original J-7 needs to be replaced, and the exported J-7 series fighters also need to be replaced.

Although most of the original J-7s have been sold, there are still some in active service in the military.

At present, the Chinese Air Force has about 125 American third-generation fighters. The largest number of domestic aircraft is the J-7 modification and the J-8 modification. The current number of the two is about 600, and another 400 will be produced in the future. Both of these models have reached the level of second-generation and a half fighters; a small number of J-7s and J-8s have been modernized, and there are about 30 of them in total.

There are currently 72 J-10 fighters, 96 J-11 fighters, and a total of 168 advanced training aircraft of various types.

The Chinese military currently has 250 ‘Ray Sculpture’ helicopters.

It is conceivable that the entire Panshan Group has a demand for aviation engines. One aircraft requires more than just one aviation engine.

At this time, the workers are producing wholeheartedly.

Modern production lines, modern production organization methods, this kind of modern production factory is very efficient.

A J-7 series aviation engine like this can meet a quarter of the demand every year.

Only 4 such factories are needed to meet the national demand for J-7 series aviation engines.

Liu Tao inspected it before leaving and went to the production line of the J-10 and J-11 fighter aircraft engines. The pulsating production line here is the most concerned because it is directly related to the production of J-10 and J-11 fighters.
