It turned out that Gu Cheng was right, and the people from the Natural Fund finally walked away.

Gu Cheng is not afraid that they will stumble on himself in the back, and the trick that can be driven out is nothing more than to ask some scientists or scientific research institutions not to go to the Tianqing Science Foundation and cut off from the upstream.

So the question is, if you don't apply for funding from the Tianqing Science Foundation, can the Natural Science Foundation allocate funds?

If not, it's impossible to stop it.

Gu Cheng's foundation for maintaining this huge scientific and technological empire is, in the final analysis, the core technology, which has not changed before, has not changed now, and will not change in the future.

He doesn't mind raising a group of scientists under his command to enrich Tianqing Technology Group, and its bottom-up building from basic science to applied science is not one or two, but the entire system.

As long as you have real skills, as long as you do academics, you can't see it today, but it will be shown in the future, and the future of Tianqing Technology Group will inevitably be diversified development.

……

The Tianqing Science Foundation caused an uproar in the academic community, and Gu Cheng's working hours had to be increased after this foundation, so he adjusted his working hours and increased his routine working hours by one hour, that is, the working hours of each working day changed from the previous three hours to four hours.

Two hours in the morning generally deal with the affairs of Tianqing Science Foundation, plus some daily office, and two hours in the afternoon is used for Pan Technology.

The time arrangement is extremely sufficient, and the working hours have been increased by 33% at once, and Gu Cheng feels that there are few people who work as hard as him.

……

In the afternoon of the next day, Gu Cheng came to Tianqing Industrial R&D Center.

Engaged in a Tianqing Science Foundation, 200 billion yuan per year funded by scientific research funds, the company has saved more than 400 billion yuan from its inception to the present, it took almost two and a half years, he decided to spend nearly half of a sentence, the company's own operation also requires huge expenses, do not earn more small money, and Tianqing Technology will be hollowed out in a few years.

The gold-swallowing ability of basic research is a bottomless pit.

"Boss, more than a dozen partners in the electromagnetic weapons project have already brought their technical backbones over." When he came to the R&D center, Zhou Huang came to report when he learned about it.

Xiao Zhou is now Gu Chengdeli's development assistant, although he does not have the name of an assistant, but when he has an assistant, although he is still on Gu Cheng's red list.

"How many are there?" Gu Cheng asked.

Zhou Huang took out a tablet from his belt, looked at it and said, "There are 228 people in total." ”

"It's a little less, but it's pretty much the same." Gu Cheng nodded, and after a while, he walked to the hall of the project team.

The current focus is to get electromagnetic weapons out and open up new business growth points for the company.

The so-called electromagnetic orbital weapon, which is simply composed of two fixed parallel guide rails and an armature that slides along the axis of the guide rail, is an electrical energy weapon that uses electromagnetic acceleration technology to fire projectiles, and can also be included in the high-energy weapons.

The principle, simply put, is that during launch, a strong electromagnetic force (Lorentz force) causes the projectile to reach an extremely high initial velocity and fly away from the guide. And this initial velocity is much higher than that of a projectile fired by a conventional chemical propellant, and the range is also long.

Traditional thermal weapons that use gunpowder as the firing energy source can accelerate the projectile to about 1.8 km/s, which is close to the limit of the speed of the projectile launched by chemical energy.

The limits here, of course, do not include the means of rocket propulsion.

However, with the development of military science and technology, the speed that can be obtained by using chemical energy to launch projectiles is far from being able to meet the needs of current anti-armor, air defense, and interception high-speed missile technology.

For example, the spherical chariot of Tianqing Technology Group, which focuses on foreign trade exports, has its armor defense capability, and the traditional tail stable shelling armor-piercing projectile has no temper at all, which makes the spherical chariot ignore the enemy's firepower and run rampant on the battlefield unscrupulously.

The shield is already ahead, and the spear is already behind.

In this case, the emergence of electromagnetic orbital weapons that use electrical energy to launch projectiles is also a trend in technological development.

In order to break the armor structure of spherical combat vehicles, armor-piercing projectiles fired by chemical energy cannot be used, but projectiles fired by electromagnetic weapons.

Gu Cheng came to the hall of the project department and looked around, 200 relevant technical R&D personnel had gathered here early, and the big guys were all from the technical backbone of more than a dozen military enterprise groups, and some were old friends.

For a while, the conversation was hot, and with the arrival of Gu Cheng, more than 200 people in the project hall noticed it.

Suddenly, the noisy discussion came to an abrupt end.

"There are so many people, let's not introduce ourselves one by one." Gu Cheng looked at his watch and said with a smile: "When the introduction is over, my off-duty time is basically up, so let's get straight to the point." ”

The hall was quiet, only Gu Cheng's voice, the researchers present were all experts in this field, but for the young Gu Cheng on the stage, they did not have too much prejudice because of their age, although the boss's notice required them to come here with a learning mentality, to be honest, it was almost clear that their research and development strength was not as good as Tianqing Technology.

But then again, the giant of Tianqing Technology Group was created by him, and the instructions of the superior leaders show that Tianqing Technology should not be simple in this field.

Gu Cheng didn't know what these researchers from the partners were thinking, and he didn't need to know, he said in an orderly manner:

"The concept of electromagnetic weapons is not born today, to this day, the problem of principle has been basically solved, but because there are still some problems to be solved in engineering technology and manufacturing process, so its development is still in the experimental stage, whether the scientific research institutions of various countries have actually used it, because they are in a state of secrecy, I don't know, but you can come here, it means that your company should be in the experimental stage in the field of electromagnetic weapons."

After a simple opening, Gu Cheng motioned for everyone to look at the main screen in the hall, and immediately called up some data and said: "According to the different structures, there are three kinds of electromagnetic weapons, namely railguns, coil guns, and heavy guns. ”

After a while, Gu Cheng looked at everyone: "But our project does not use the idea of parallel guide rails, but uses coaxial coils, that is, coil guns, because the light electromagnetic weapons we want to do are positioned in the project." ”

Speaking of this, Gu Cheng called up a theoretical model on the big screen and introduced: "The coaxial coil is composed of a series of specified acceleration coils around the gun chamber and the projectile motion coil around the projectile, which uses the electromagnetic force generated when the acceleration coil and the projectile coil are mutually inducted as the acceleration force of the projectile. ”

"When the acceleration coil is suddenly added with a current, a corresponding induced current will be generated in the projectile coil, and then the two coils are equivalent to two electromagnets, they repel each other, and the force received by the projectile coil is the acceleration force, which is used to supply power to the acceleration coil when fired, so a magnetic field moving along the barrel tube is generated, and this magnetic field interacts with the magnetic field excited by the induced current in the projectile coil to produce a continuous acceleration force, so that the projectile accelerates."

The R&D personnel present were more surprised, they originally thought that they were going to engage in railguns, but they didn't expect it to be coil guns.

Gu Cheng paced back and forth and said:

"It should be noted that the interaction between the acceleration coil and the projectile coil is equivalent to the interaction between two magnets, which can both repel and attract, and the performance is that it can both accelerate and slow down the projectile."

"Therefore, it is necessary to ensure that the magnetic field generated by the acceleration coil is precisely synchronized with the motion position of the projectile coil, and the coaxial coil has three major advantages over parallel tracks."

"First, the acceleration force is large, and its acceleration force peak is 100 times that of the parallel guide."

"Second, because the projectile in the coaxial coil is not in direct contact with the gun chamber, it moves by magnetic levitation, so there is no friction between the barrel and the projectile, and the acceleration force is applied to the entire projectile, so that the energy utilization rate is high, and the accurate data given by the theoretical model is 57.55%."

"Thirdly, the current required is much smaller than that of the track, and there is no megaampere-level pulse current, which can simplify the switchgear."

"Because of these characteristics and advantages, coupled with the energy core technology of our Tianqing Technology Group, which solves the power supply problem, it is possible to develop electromagnetic rifles and miniaturize electromagnetic weapons."

Gu Cheng has never been a person who drags mud and water, as the development team reaches the scale requirements, he immediately enters the actual development link, and quickly distributes the task, and the technical development team of more than 200 people is divided into four groups, each of which is subdivided into more than a dozen groups, each responsible for their own modules.

And Gu Cheng is in charge of the overall information.

There are four main links: power supply design, electromagnetic emitter design, overall system design, and materials.

The electrical energy required by electromagnetic weapons has been solved, that is, the miniaturized superconducting battery energy storage, for the consideration of firearm design, the power supply design, the energy core and the electromagnetic rifle are separated, when in use, the operation is also very foolish, simply put, the soldier finds the line of the energy core and connects it to the interface on the electromagnetic rifle to be energized.

The weapon must be the simpler the more combative.

The battlefield is changing rapidly, and if the weapon operation is complicated, it will be killed by the enemy long ago.

The detachable design improves safety, reduces the space of the electromagnetic rifle itself, and makes it easy to replace and maintain.

To put it bluntly, on the premise of ensuring that there will not be too much difference in power, the cost should be reduced as much as possible, including manufacturing costs, maintenance costs, and so on.

The design of the electromagnetic transmitter is one of its core technologies.

First of all, it is necessary to design according to the requirements of the use of the weapon system, and determine which launch principle and method to use; Secondly, according to the determined projectile function, the pulse power of the required power supply is calculated, so as to determine the best power supply mode. Again, it is necessary to study the structural form of the launcher, including the gun body, ammunition feeding system, etc.; Finally, it is necessary to form a prototype that can realize the launch cycle under laboratory conditions to conduct launch tests, test relevant data, and modify and improve the prototype to provide the necessary data parameters for the design of the entire weapon system.

As for the material.

There is nothing more suitable than the magic carbon acetyne material, although it cannot be said that it is a universal material, but at present, the products of Tianqing Technology are just indecisive, and the carbon acetyl is solved.

When the electromagnetic weapon is launched, it is to accelerate the projectile under the condition of strong pulse current, and its working conditions are extremely harsh, therefore, the materials used in it have high requirements, whether it is coil, insulation, conductor and other property requirements, carbon ylene materials can be perfectly competent, and carbon ylene has its unique conductive properties, which can be changed from a conductor to an insulator by only 3% stretching.

It can be said that carbyne materials are an indispensable core material for building electromagnetic weapons, and some key modules involved are irreplaceable so far.

The second is the choice of projectile material.

The projectile material of the current electromagnetic gun is mostly light metal, and its external ballistic characteristics have not yet been considered, and the projectile material must be required to be able to withstand the acceleration produced by the acceleration in the chamber much higher than that of the traditional thermal weapon, the acceleration of the electromagnetic weapon is hundreds of thousands of times the acceleration of gravity, coupled with the high-speed collision with the armored target, its hardness is a vital attribute, and once the speed of the projectile reaches more than 3 km/s, the frictional heat generated when it flies at high speed in the air is enough to melt the projectile of ordinary materials.

Therefore, the projectile material not only requires high hardness, but also ablation resistance.

There is no doubt that there is currently no material that better meets the requirements for the properties of a projectile than carboxylene alloys.

However, there is a problem, the value of carboxylene alloy is more expensive than natural carboxylene, and the big dogs can't stand it when they make consumables with this new alloy material worth tens of millions of dollars a ton.

What's more, natural carboxylene is a non-renewable resource, and using it to make projectiles is simply outrageous.

Gu Cheng's choice of projectile materials is based on iron materials, which are low in cost, and the shell is coated with a layer of anti-corrosion, anti-rust, and high-temperature resistant alloy materials.

Alloys such as oxygen-free copper, or steel with tungsten, zirconium, thorium, nickel, chromium, etc., can be considered.

In short, any alloy material can be used to make a projectile, but you can't use a carboxylene alloy.

I can't afford to hurt it!
