The rise of a great power: starting with military industry

Chapter 913 Pulsating Assembly Line

Hotel banquet hall.

Thousands of mathematicians gathered here.

This is a celebratory reception organized by Southwest Associated University.

Liu Tao had a smile on his face and a wine glass in his hand as he communicated with the mathematicians one by one.

Liu Tao knew some of the domestic mathematicians, but not most of them.

For example, Liu Tao knows all the academicians, and he also basically knows all the outstanding national youths. As for the others, Liu Tao only knows some of them.

Liu Tao basically doesn't know any overseas mathematicians.

The only one that I am relatively familiar with is Vitton.

It’s 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 is great enough to completely establish his identity and status as one of the world's top mathematicians.

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 over the past 350 years, many mathematicians have made important contributions to proving Fermat's Last Theorem.

Euler expanded the application of imaginary numbers, Kummer established the theory of ideal numbers, Faltings proved the Model conjecture, and Ken Batry proved the Frye proposition.
Fermat's Last Theorem has spawned so many new ideas and new achievements that Hilbert once likened Fermat's Last Theorem to "a goose that lays golden eggs", and his words were 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.

In proving Fermat's conjecture, Liu Tao built a solid bridge connecting the two isolated mathematical islands of elliptic curves and modular forms, in which many modern mathematical achievements were perfectly integrated, adding a strong stroke to the idea of ​​the grand unification of mathematics foreshadowed by the Langlands Program, making the prospect of the grand unification of mathematics more clearly visible.

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

He came to an aircraft engine factory, which specialized in producing laser-engraved helicopter aircraft engines.

In normal aircraft engine assembly, after the compressor, turbine and other large components are assembled, the test bench is transferred to a horizontal position and then to the next workstation to install external piping, additional casing 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 a pulsating assembly line has shortened the assembly cycle by more than one third.

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

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

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

This output is already very high.

只需要4条脉动式总装生产线，歼10或者歼11战斗机的年产量便可以达到100架。盘山集团对于航空发动机的需求量是十分巨大的，既需要歼7的各类型航空发动机，还得歼8的各类型航空发动机，便是歼教7高教机、歼7A高教机、雄鹰高教机的航空发动机需求量都非常大，歼10战斗机、歼11战斗机这两款的发动机需求更不要说。

There is also a huge demand for engines for laser engraving helicopters.

Without the pulsating assembly production line, it would be impossible to meet the needs of Panshan Group.

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

Panshan Group has aviation engine factories like this not only at the 011 Aviation Base, but also in other places.

After all, this is done from a security perspective, to ensure that even if the entire 011 aviation base suffers a devastating blow, aircraft engines can still be produced and aircraft manufactured elsewhere.

This is bottom-line thinking.

Although this will result in less than ideal production efficiency, it is necessary for safety.

All major countries in the world do this.

The same goes for not only aircraft engines, but Panshan Group has also set up aircraft production lines in other places instead of concentrating all aircraft production lines at the 011 Aviation Base.

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

After inspecting this aircraft engine factory, Liu Tao went to inspect another aircraft engine factory, which is specialized in producing different aircraft engines required for the J-7 series. The J-7 series' self-use version of the aircraft engine has been replaced with the latest model, which can have more powerful aircraft engines, making the aircraft have greater speed and greater maneuverability.

There are differences between the domestic version of aircraft engines and the export version of aircraft engines. The difference is not only reflected in the service life of the aircraft engines, but also in the performance. The export version of aircraft engines is roughly equivalent to 70% of the domestic version of aircraft engines.

The engines needed for the J-7 modification are the largest in scale. Not only because the latest J-7 modification needs engines, but also the existing J-7s and the exported J-7 series fighters need to be replaced.

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

Currently, the Chinese Air Force has about 125 American third-generation fighter jets. The most numerous domestically produced aircraft are the J-7 and J-8 modified models, with a current number of about 600. Another 400 will be produced in the future. Both models have reached the level of second-generation and a half fighter jets; a small number of J-7s and J-8s have been modernized, with a total of about 30 aircraft.

歼10战斗机目前有72架，歼11战斗机有96架，各类型高教机总共有168架。

The Chinese military is currently equipped with 250 "Ray Sculpture" helicopters.

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

At this time, the workers are producing wholeheartedly.

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

A J-7 series aircraft engine like this one can meet a quarter of the demand each year.

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

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