Chapter 238 [Development of Electromagnetic Weapons]

Facts proved that Gu Cheng was right, and the people from the Natural Science Fund finally left in despair.

Gu Cheng is not afraid that they will trip him up from behind. The trick he can do is to stop some scientists or scientific research institutions from going to the Tianqing Science Foundation and cut off from the upstream.

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

If not, it is impossible to stop it.

The foundation of Gu Cheng's maintenance of this huge technology empire is ultimately the core technology. This has not changed before, it has not changed now, and it will not change in the future.

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

As long as there is real ability, as long as you do academics, you can't see it today, but it will be revealed in the future. The future of Tianqing Technology Group must be diversified.

……

The Tianqing Science Foundation caused an uproar in the academic circles. With this foundation, Gu Cheng's working hours had to be increased. For this reason, he adjusted his working hours and increased his routine working hours by one hour, that is to say, every The working hours of the working day have changed from the previous three hours to four hours.

The two hours in the morning are generally used to deal with the affairs of the Tianqing Science Foundation, plus some daily office work, and the two hours in the afternoon are used to promote technology.

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

……

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

The Tianqing Science Foundation was set up, with 2000 billion yuan of scientific research funds as the foundation every year. The company has accumulated more than 4000 billion yuan of wealth since its establishment. It took almost two and a half years. He decided to spend it in one sentence. Nearly half of the time, the operation of the company itself also requires huge expenses. If you don't earn more small money, Tianqing Technology will be hollowed out in a few years.

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

"Boss, more than a dozen partners of the electromagnetic weapon project have brought their technical backbones here." When he came to the R&D center, Zhou Huang came to report after learning about it.

Xiao Zhou can now be regarded as Gu Cheng's development assistant, although he is not named as an assistant, but when he has an assistant, even though he is still on Gu Cheng's red list.

"How many people?" Gu Cheng asked.

Zhou Huang took out a tablet from his belt, looked at it and said, "A total of 228 people."

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

The current focus of work is to develop electromagnetic weapons and open up new business growth points for the company.

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

The principle, simply put, is that during the launching process, the powerful electromagnetic force (Lorentz force) makes the projectile fly away from the guide rail at a very high initial velocity.And this initial velocity is much higher than the initial velocity of the projectile launched by conventional chemical propellants, and the range is also far.

Traditional thermal weapons using gunpowder as the energy source for launching can accelerate projectiles to about 1.8 km/s, which is already close to the limit of the speed of projectiles launched by chemical energy.

Of course, the limit here does not include the rocket propulsion method.

However, with the development of military science and technology, the speed 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 technologies.

For example, the spherical chariot of Tianqing Technology Group, which is mainly for foreign trade export, has armor defense capabilities, and the traditional tail-stabilized shell-piercing armor-piercing projectile has no temper for it. This makes the spherical chariot ignore the enemy's firepower and run wild on the battlefield. superior.

The shield has gone ahead and the spear has fallen behind.

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

To break the armor structure of a spherical chariot, armor-piercing projectiles launched by chemical energy will not work, but projectiles fired by electromagnetic weapons must be relied on.

Gu Cheng came to the lobby of the project department and looked around. Two hundred related technical R&D personnel had gathered here early. The big guys came from technical backbones of more than a dozen military industrial enterprise groups, and some were old friends.

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

Suddenly, the noisy discussion stopped abruptly.

"There are so many people, so let's not introduce ourselves one by one." Gu Cheng looked at his watch and said with a smile: "After the introduction is over, it will be almost time for me to get off work, so let's get straight to the point."

The hall was quiet except for Gu Cheng's voice. The researchers present are all experts in this field, but they didn't have too much prejudice against the young Gu Cheng on the stage because of his age. They came here with a learning mentality, and to be honest, they were short of saying that their research and development strength was not as good as Tianqing Technology.

But having said that, he was the one who created the giant of Tianqing Technology Group. Such instructions from the superiors show that Tianqing Technology should not be easy 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 methodically:
"The concept of electromagnetic weapons was not just born today. Today, the problems in principle have been basically solved, but because there are still some problems to be solved in engineering technology and manufacturing technology, its development is still in the experimental stage. I don’t know whether the scientific research institutes in China have actually used it, since they are all in a state of secrecy, but everyone can come here, which shows that your company should be in the experimental stage in the field of electromagnetic weapons.”

After a simple opening, Gu Cheng motioned 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 types of electromagnetic weapons, namely rail guns, coil guns, and reconnection guns. The one that is relatively rapid, relatively mature in theory and practice, and closest to weaponization is mainly electromagnetic rail weapons, or electromagnetic rail guns to be precise."

After a while, Gu Cheng looked at everyone: "But our project does not adopt the idea of ​​​​parallel guide rails, but uses coaxial coils, that is, coil guns, because the project we are going to target is a light electromagnetic weapon."

Having said that, Gu Cheng called up a theoretical model on the big screen, and introduced: "The coaxial coil is composed of a series of fixed acceleration coils around the gun bore and a bullet-borne moving coil around the projectile. The electromagnetic force generated by the mutual induction between the coil and the bomb-borne coil is used as the acceleration force of the projectile."

"When a current is suddenly applied to the acceleration coil, a corresponding induced current will be generated in the projectile coil. At this time, the two coils are equivalent to two electromagnets, and they repel each other. The force received by the projectile coil is the acceleration force. When launching This is used to supply power to the accelerating coil, thereby generating a magnetic field that moves along the gun barrel, and this magnetic field interacts with the magnetic field excited by the induced current in the projectile coil to generate a continuous acceleration force, thereby accelerating the movement of the projectile."

The R&D personnel present were quite surprised. They originally thought they were going to make a rail gun, but they didn't expect it to be a coil gun.

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 repel or attract each other, and the performance is that the projectile can be accelerated or decelerated. "

"Therefore, it is necessary to ensure that the magnetic field generated by the accelerating coil is precisely synchronized with the moving position of the projectile coil. The coaxial coil has three advantages compared with the parallel track."

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

"Second, because the projectile in the coaxial coil does not directly contact with the barrel, it moves by magnetic levitation force, so there is no friction between the barrel and the projectile, and the acceleration force is applied to the entire projectile, which makes the energy utilization rate high , the exact data given by the theoretical model is 57.55%.”

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

"Because of these characteristics and advantages, and the energy core technology of our Tianqing Technology Group solves the power supply problem, the development of electromagnetic rifles has become possible, and the miniaturization of electromagnetic weapons has become possible."

Gu Cheng has never been a procrastination person. As the development team reached the scale requirement, he immediately entered the actual development process and quickly distributed the tasks. The technical development team of more than 200 people was divided into four large groups, and each large group was detailed. Divided into 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 transmitter design, overall system design, and materials.

The electrical energy required by electromagnetic weapons has been solved, that is, the energy storage of miniaturized superconducting batteries. For the consideration of firearm design, in terms of power supply design, the energy core is separated from the electromagnetic rifle. When in use, it is easy to operate It is also very foolish. Simply put, the soldiers find the line of the energy core and connect it to the interface on the electromagnetic rifle to power on.

Weapons must be simpler and more effective.

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

The separate design can improve safety, and at the same time reduce the space of the electromagnetic rifle itself, and the replacement of supplies and maintenance are also simple.

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

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

First of all, it must be designed according to the requirements of the weapon system to determine which launch principle and method to use; secondly, according to the determined projectile function, calculate the pulse power of the required power supply to determine the best power supply method; The structural form of the launcher, including the gun body, the bomb supply system, etc.; finally, it is necessary to form a principle prototype that can realize the launch cycle under laboratory conditions, conduct launch tests, test relevant data, and use this to modify and improve the principle prototype. The design of the weapon system provides the necessary data parameters.

As for materials.

There is nothing more suitable than the miraculous carbyne material. Although it cannot be said that it is a universal material, as far as the products of Tianqing Technology are concerned, carbyne will solve the problem of materials.

When the electromagnetic weapon is launched, the projectile is accelerated under the condition of strong pulse current, and its working conditions are extremely harsh. Therefore, the requirements for the materials used are very high. Regardless of the requirements for properties such as coils, insulation, and conductors, carbyne materials can be perfect. Competent, carbyne, with its unique conductive properties, can change from a conductor to an insulator by only being stretched 3%.

It can be said that carbyne material is an essential core material for building electromagnetic weapons. For some key modules involved, carbyne material is 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 been considered yet, and the projectile material must be able to withstand the acceleration produced by the acceleration in the bore, which is much higher than that of traditional thermal weapons. The acceleration of electromagnetic weapons is the acceleration of gravity Coupled with the high-speed collision with the armored target, its hardness is a crucial attribute, and once the speed of the projectile reaches more than 3 kilometers per second, the friction generated when it flies in the air at high speed The heat is also enough to melt the projectiles of ordinary materials.

Therefore, the projectile material not only requires high hardness, but also is resistant to ablation.

There is no doubt that there is currently no material that better meets the property requirements of projectiles than carbon yne alloy.

However, there is a problem. The value of carbyne alloy is more expensive than that of natural carbyne. Using this new type of alloy material worth tens of millions per ton to make consumables is unbearable for big dogs.

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

The core of Gu Cheng's choice of projectile material is to use iron material, which has low cost.

Alloys such as oxygen-free copper, or steel with tungsten, zirconium, thorium, nickel, chromium, etc. are contemplated.

In short, any alloy material can be used to make projectiles, but carbyne alloy cannot be used.

Can not afford to hurt ah!
