Li Changfeng's life has returned to calm again.

After the envoys of the Western world established diplomatic relations with the great cadres, they did not leave in a hurry and wandered around the capital to buy things, but this had nothing to do with him.

He devoted all his energy to nuclear weapons research.

In the blink of an eye, half a year has passed.

The complicated processes such as precipitation, solvent extraction, and ion exchange required for the separation of immersion water have all been broken through, and the relevant solvents have been blended and small-scale experiments have been done.

The results are encouraging.

Although there are still some problems, the required nuclear materials are still separated.

The next step is ion exchange resin filtration, where heating and gasification are very troublesome and require a lot of electricity support, and many of these key technical difficulties have not yet been broken.

There is both theory and direction, all that is needed now is patience and time.

At this time, the construction of the second hydropower station in Daqian was about to be completed and put into operation, and Li Changfeng ordered the construction of a nuclear raw material extraction plant near the hydropower station to prepare for the next step of filtration to make yellow cakes.

Yellowcake is a common name for uranium concentrate in the form of diuranicate or uranate.

The next step is to purify the purer uranium concentrate, and when it is brown or black, it indicates that its purity is basically up to standard, and it can be used for subsequent nuclear weapons manufacturing processes.

At this point, Li Changfeng handed over the follow-up research to Liang Dafu and the Nuclear Weapons Research Institute, and went to the automobile factory to inspect.

The light truck based on the Changfeng automobile engine has completed road tests and load durability tests, and today is the day of the final test before it is officially put into production.

For the development of the entire industrial system, this day is of great significance, and Li Changfeng naturally wants to personally inquire about it.

When I came to the R&D workshop, it was already full of people.

After everyone finished worshipping, He Yongyan, president of the Mechanical Research Institute, began to introduce.

"Your Highness, let's talk about the engine first, we have improved the cylinder structure, the volume of the cylinder has also been expanded, the power has been greatly improved, and the durability has been tested, and there is absolutely no problem!"

As he spoke, He Yongyan took Li Changfeng to a disassembled engine and began to introduce it in detail.

Li Changfeng listened to the test, and there was no need to be impatient at all.

The process of listening is the process of learning, which will make his mind more open, and he can remember more relevant knowledge from his previous life, and he will build a more powerful engine after he is done.

Ultimately, it's about building airplanes.

This is crucial.

Think about it, what is the use of nuclear weapons if they are researched but do not have the ability to deliver them?

As for what precision-guided missiles, intercontinental ballistic missiles, he can't even think about now.

Compared to propeller planes, this is just too complicated.

In the end, He Yongyan said: "Of course, the disadvantage is not nothing, that is, the fuel consumption has increased, which will lead to an increase in the cost of use." ”

Li Changfeng said with a smile: "The increase in horsepower will inevitably lead to an increase in fuel consumption, which is normal, don't mind, in the future, you can make a fuss about the combustion ratio and compression ratio, and the fuel consumption may be reduced." ”

He Yongyan nodded: "Well, this has been mentioned by Dean Liang before, and it is a future research topic, okay, let's take a look at the truck chassis again, this thing is very important for a truck." ”

In this regard, Li Changfeng did not have the slightest interest.

"The prince of the chassis will not look at it, and go directly to the finished product."

"Yes, Your Highness."

He Yongyan didn't talk nonsense, and directly brought Li Changfeng to the sample that was about to be mass-produced.

After seeing the real car, Li Changfeng couldn't help but twitch his cheek.

At the beginning, he considered the need to transport goods for long and short distances, and at the same time to sleep in the car, so he directly drew a drawing of the Wuling double-row truck based on his memories of his previous life, and asked them to make it according to this shape.

His expectation was a little bit of a look.

As a result, the actual car in front of him greatly exceeded his expectations.

Some details have been changed, and if you add a Wuling logo, it is almost exactly the same as the Wuling god car in the previous life.

For a while, Li Changfeng had a feeling of time and space confusion.

Seeing his strange expression, He Yongyan asked a little nervously, "Your Highness, is there a problem?" ”

Li Changfeng came back to his senses and said with a smile: "There is no problem, it has exceeded the expectations of this prince, very good!" ”

He Yongyan suddenly breathed a sigh of relief, opened the car door and introduced.

"In line with the principle of cost saving and practicality, the cab is very simple and ......"

Li Changfeng watched quietly.

Where is this simple, it can only be described as simple.

There is nothing but the pedals used to steer the car, as well as the handbrake and steering wheel.

The only commendable thing is that due to Li Changfeng's special reminder, the seat is not the kind that goes straight up and down, it is somewhat ergonomic, which is very important to the driver.

As for the back row, it's even more rudimentary, it's just a bench with a backrest, made of metal, and there are no two cushions.

Li Changfeng has no dissatisfaction with this.

At the beginning of the design of this car, Li Changfeng's request was to reduce the cost as much as possible, so that the price of the truck could be lowered and more businessmen and ordinary people could afford it.

Changfeng brand trucks should become the entrepreneurial partners of the people and gallop in all corners of Daqian.

After the introduction, Li Changfeng personally got into the car and drove for a while, the gear shift was smooth and the horsepower was strong, and there was no problem with pulling goods.

"The car is fine, so the car factory will immediately put it into mass production."

Because there are no wagons, the railway and road networks that Daqian is building are still transporting construction materials by horse-drawn carts, ox carts, and rickshaws, which is very inefficient.

The advent of trucks will inevitably greatly improve the efficiency of construction, which is very important for him to promote the process of industrialization of the Great Qian.

He Yongyan naturally knew the importance of the truck, and nodded solemnly and said, "Your Highness, rest assured, the automobile factory has made sufficient preparations and can start production today." ”

"Very well, how is the development of the diesel engine engine progressing?" Li Changfeng asked.

At present, the load capacity of this gasoline-fueled light truck is not strong enough.

If you want to pull more and heavier cargo, you have to use a diesel engine with a torque far higher than that of a gasoline engine.

He Yongyan said: "Dean Liang has taken us to study the diesel engine before, we have mastered the basic principles, and there is even a less mature prototype, and we will invest more time and energy in the future, and I think it will soon be applied to practical applications." ”

Li Changfeng nodded with satisfaction: "Very good, some core researchers will be dispatched to carry out technical research on diesel engines, and then you will lead some researchers to start new research." ”

He Yongyan suddenly became interested: "What are you studying?" ”

Li Changfeng didn't say it right away, and said: "Have you ever imagined using the power generated by the engine to make something like a bird fly under the control of a person?" ”
