The Power of the Hk326 Electromagnetic Gun!

Shuangqing University, No. 1 Doctoral Dormitory Building, 501 Dormitory.

Shi Lei was very satisfied with the noise control of Shadow Dragon. In order to test the control flexibility of the Shadow Dragon, Shi Lei directly used the small environment of the 501 dormitory to conduct the test in Shi Lei.

Controlling the U-shaped joystick, Shadow Dragon moved flexibly in the small bedroom space. Handling is excellent, especially when it comes to changing directions.

Due to the bottom of the cabin of the Shadow Dragon, three cameras are used to monitor the scene in real time, and the Shadow Dragon is a symmetrical design of four propellers.

When changing directions, you don't need to turn at all, you can go straight forward, or go straight back, or any other direction. Compared with the steel number, this has obvious advantages. [

The good control performance allows the Shadow Dragon to move freely in a small space without being restricted at all.

Slowly landing the Shadow Dragon, Shi Lei nodded in satisfaction, the Shadow Dragon already had two advantages. Whether it is flexible control performance or noise control, it is very suitable for complex urban environments.

Especially the flexible operation performance, in the urban environment, will let the Shadow Dragon handle with ease.

"Little Lizi, how is Shadow Dragon's defense?" Shi Lei asked with a worried look.

Whether it's a thin-looking propeller blade or a live-action capture camera exposed outside. Not like anything with high defense.

Li guessed the next words, confirmed this!

"Brother Stone, the defensive power of the Shadow Dragon can't be compared to that of the Steel! After all, the Steel is made of special aviation metals, while the Shadow Dragon is only made of aluminum alloy. Whether it is a pistol, a miniature submachine gun, or even a high-altitude parabolic It may cause fatal damage to Shadow Dragon." Li Guai said a little embarrassedly.

But Li Chai immediately continued: "Brother Stone, although the Shadow Dragon's defense is not good, its cost is far lower than that of the Iron and Steel! The Shadow Dragon without the weapon module costs just a little more than 10,000 yuan! Most of the cost is concentrated in the onboard computer, high-efficiency lithium batteries, and ranging radar and cameras. These parts can be recycled and reused.”

Shi Leinai nodded. After all, the cost was only one-tenth, and Shi Lei was not surprised by the answer. Because how to look at the shadow dragon, how is it not like a high defense body.

The positioning of the shadow dragon is more to perform tasks in the urban environment, security issues in the city, and most criminals will not have firearms. Therefore, it is harmful to the Shadow Dragon Law!

In the small CNC machining center, the barrel of the electromagnetic gun was finally processed. Li Guai opened the hatch of the small CNC machining center and took off the gun barrel from the tooling. With a strange smile, he rubbed the section of about ten centimeters. silver-white metal tube.

Shi Lei felt a chill in his heart, and Xiao Lizi's movements were too obscene, as if he was masturbating

"Little Lizi, pay attention to your image!" Shi Lei couldn't help reminding him.

Li Guai smiled, "Brother Stone, don't underestimate this barrel, although it's only 10m long, it costs 2,000 yuan!"

"It's so expensive?" Shi Lei looked at the unremarkable short tube and didn't understand why it was so expensive.

Li Gu explained: "Brother Shitou, this is a special metal that can better adapt to electromagnetic effects and allow the gun to reach a higher initial speed! It cost 20,000 yuan just to process its special diamond bit! It's a bit pricey, but the effect should be very good!"

"Try it?" Shi Lei said expectantly.

"I'll assemble it first!" Li Guai took the 10m electromagnetic gun barrel, came to the workbench, put the gun barrel through the lock, and installed it into the mechanical device just now.

That mechanical device is the accelerator and switch part of the core device of the electromagnetic gun. The electromagnetic gun mainly has three parts, the energy device, the accelerator and the switch. [

The energy source is provided by Shadow Dragon, and Li Guai designed the accelerator and switch in the same part. The switch part should also be connected to Shadow Dragon and handed over to Shadow Dragon for automatic control.

After the installation of the gun barrel was completed, Li Gu took out a bag of steel balls and put it into the supply system of the electromagnetic gun. The miniature electromagnetic gun designed by Li Chai uses a solid steel ball with a weight of 5 grams.

Li Guai introduced the basic parameters of the miniature electromagnetic gun to Shi Lei while installing it. "Brother Stone, based on the energy situation of the Shadow Dragon, it can only support 50 shots at most. And each shot will consume about 1 minute of airborne power."

Shi Lei's eyebrows were huddled together, and one shot took 1 minute to stay in the air. It was really a luxury electromagnetic cannon!

"How's the power?"

Li Guess found a piece of scratch paper on the workbench and handed it to Shi Lei: "The calculated data shows that the power is quite impressive. The initial speed of a 5-gram solid steel ball reaches the level of 800 meters!"

Shi Lei didn't quite understand the meaning of these data, so he said directly: "Little Lizi, give me a distance explanation, how powerful is the miniature electromagnetic gun!"

As the saying goes, there is a specialization in the art industry. Shi Lei is a super genius in the computer industry, but in the machinery industry, he has become a rookie.

Although Li guess doesn't understand computer knowledge, he understands what Shi Lei doesn't.

"Brother Stone, according to the calculation formula of kinetic energy, e1\2mv2, that is, kinetic energy is equal to half of the mass multiplied by the square of the speed. The speed of the miniature electromagnetic gun is 800 m/s, the weight of the solid pill is 0005kg, and the kinetic energy is 1600 joules. This is an amazing number!" After Li Guess finished explaining, he found that Shi Lei was still in a confused state, obviously explaining it in vain!

Shi Lei coughed: "Say it directly, it's as powerful as something!"

Li Guai thought about it for a while, and then gave an example: "Brother Stone, do you know the m4 carbine?"

In the past life, the m4 carbine was Shi Lei's favorite. It was excellent in terms of shooting speed, accuracy, or range.

"Well, I know!" Shi Lei nodded and said in surprise, "Could it be similar in power to the m4 carbine?"

Li guess nodded, "That's right! The m4 carbine's muzzle velocity is 880m/s, the muzzle kinetic energy is 1645 joules, and the sub-weight is slightly less than 5 grams. Our miniature electromagnetic gun is a little different from the carbine in terms of kinetic energy. It's just the difference in power!"

After listening to Li Gu's explanation, Shi Lei realized the mistake of his previous idea about the power of the electromagnetic gun. It turned out that the power can not only be determined by the speed, but also by the mass of the pill, and the kinetic energy of the final combination.

Kinetic energy is energy!

The higher the energy, the greater the destructive power, and the higher the power!

There is another example to illustrate the power of the miniature electromagnetic gun, that is, the famous Black Star 54-type pistol, the muzzle kinetic energy is only 480 joules.

After almost understanding the power of the miniature electromagnetic gun, Shi Lei finally showed a smile. But Shi Lei raised another doubt. Although he didn't know much about physics and the conversion between energies, Shi Lei still knew that one kilowatt-hour of electricity, that is, one kilowatt-hour of electricity, was equal to many, many joules.

Why does it take one minute of the Shadow Dragon's battery life to fire an electromagnetic cannon?

Shi Lei asked his doubts, and Li Gu took out a more detailed parameter drawing and explained it to Shi Lei. [

According to the conversion of energy, one kilowatt-hour, that is, one kilowatt-hour of electricity is equal to 3.6 million joules.

The Shadow Dragon uses distributed battery energy supply, and a total of five batteries are installed, which are the four frames of the propeller and the main battery compartment of the cabin. The total capacity of the five electromagnets has reached the level of 22 kWh.

Four propellers, each with a power of 300w, the four propellers add up to 12kw, and consume 12 degrees of electricity in one hour.

The Shadow Dragon also has an on-board computer, ranging radar, and surveillance cameras, which also consume power, adding up to almost 500w, which is 05 kWh per hour.

The total power consumed by the Shadow Dragon in one hour is 17 kWh, and the total power remaining is 05 kWh, which can support more than ten minutes of flight time.

The maximum voyage is 80 minutes, which is still quite ideal!

One electromagnetic cannon only has an energy of 1600 joules. For the Shadow Dragon, which has an energy of nearly 8 million joules, why is it necessary to reduce the range of about 1 minute when firing once?

Calculated by dividing the total energy by the total time, about 8 million joules of energy, divided by about 80 minutes of flight time, about 100,000 joules per minute.

Is the difference between 100,000 joules and 1600 joules too big?

In fact, it is not. Due to the limitations of technology, materials, and the structure of miniaturized electromagnetic guns, the efficiency of Lorentz force and electromagnetic effect in converting energy is very low!

With a conversion rate of only 16, it is not surprising!

After listening to Li Gu's explanation, Shi Lei coughed and asked, "Little Li, in a word, there is still a lot of room for improvement in the future of miniature electromagnetic guns?"

"Well! It can be said that! With the improvement of our technology and craftsmanship, there will be better material input and a more advanced frame. Our electromagnetic guns will eventually become more and more powerful!" Li Guess is confident Full mouth.

Shi Lei clapped his hands and said, "I can rest assured! Little Lizi, put this electromagnetic cannon on it first. I will test it myself to see how powerful it is!"

The process of installing the electromagnetic gun is very fast, whether it is the electromagnetic gun or the mp7 submachine gun, all of them adopt a modular design.

As long as it is standard modular, it only needs the corresponding loading, and it can be completed in a few minutes!

It took Li Guess seven or eight minutes to install the electromagnetic gun and the shadow dragon together, and after checking it again, after confirming that there was no problem, he said to Shi Lei: "Brother Shi, it's no problem!"

Shi Lei checked the power information reported by the eh system, and there is still 76 power, which can last for more than fifty minutes of flying.

As the shadow dragon took off, Shi Lei controlled the shadow dragon to fly out of the living room and flew to the outside world.

Li Guai said nervously, "Brother Stone, the electromagnetic gun is very powerful. What are you going to use to test its power?"
