Shi Lei was very satisfied with Shadow Dragon's noise control. In order to test Shadow Dragon's control flexibility, Shi Lei directly used the small environment of the 501 dormitory to conduct the test in Shi Lei. The performance was very good, especially when it came to changing directions.
Because the bottom of the Shadow Dragon's cabin uses three cameras to monitor the scene in real time, and the Shadow Dragon has a four-propeller symmetrical design...
When changing direction, there is no need to turn at all. You can go directly forward, directly backward, or in any other direction. This is a very obvious advantage compared to the Steel. It allows the Shadow Dragon to move freely in a small space.
It's like there are no restrictions. It can be flexible and has noise control, which is very suitable for complex urban environments. It can be used in urban environments, which will allow Shadow Dragon to handle it with ease.
"Little Lizi, how is Shadow Dragon's defense?" Shi Lei asked with worry.
Whether it's the propeller blades that look a little thin or the exposed live-action capture camera, they don't look like anything with high defense...
Li Guai’s next words confirmed this!
"Brother Shitou, the defense power of Shadow Dragon cannot be compared with that of Steel! After all, Steel uses special aviation metal, while Shadow Dragon is only made of aluminum alloy. Whether it is a pistol, a micro submachine gun, or even a high-altitude projectile,
It may cause fatal damage to the shadow dragon." Li Chai said with some embarrassment.
But Li Chai immediately continued: "Brother Shitou, although the defense of Shadow Dragon is not good, its cost is far lower than that of Steel! The cost of Shadow Dragon without the weapon module is only a little more than 10,000 yuan! Moreover,
Most of the cost is concentrated on the onboard computer, high-efficiency lithium battery, and ranging radar and camera. These components can be recycled over and over again."
Shi Lei nodded helplessly. After all, the cost was only one-tenth of the cost, and Shi Lei was not surprised by the answer. Because no matter how you look at the Shadow Dragon, it doesn't look like a high-defense machine.
The positioning of Shadow Dragon is more to perform tasks in the urban environment. Security issues in the city. Most criminals do not have firearms. Therefore, they cannot cause harm to Shadow Dragon!
In the small CNC machining center, the electromagnetic gun barrel was finally processed. Li Chai opened the door of the small CNC machining center, took out the barrel from the tooling, and rubbed the section of about ten centimeters with a weird smile on his face.
silvery white metal tube.
Shi Lei felt a chill in his heart. Xiao Lizi's movements were too obscene, as if he was masturbating
"Xiao Lizi, you guy, pay attention to your image!" Shi Lei couldn't help but remind him.
Li Guai chuckled. "Brother Shitou, don't underestimate this barrel. Although it is only 10cm long, its price is two thousand yuan!"
"So expensive?" Shi Lei looked at the ugly short tube and didn't understand why it was so expensive.
Li Chai explained: "Brother Shitou, this is a special metal. It can better adapt to electromagnetic effects and allow the cannonball to reach a higher initial velocity! The special diamond drill bit alone to process it also cost 20,000 yuan!"
Although it is a bit expensive, the effect should be very good!”
"Try it?" Shi Lei said expectantly.
"I'll assemble it first!" Li Chai took the 10cm electromagnetic gun barrel to the workbench, put the barrel through the latch, and installed it into the mechanical device just now.
That mechanical device is the core device accelerator and switch part of the electromagnetic gun. There are three main parts of the electromagnetic gun, energy device, accelerator and switch.
In terms of energy, it is provided by Yinglong. Li Yue designs the accelerator and switch in the same part. The switch section must also be connected to Yinglong and handed it over to Yinglong Automation.
After the installation of the cannon, Li Yue took out a bag of steel beads and loaded the bomb supply system of the electromagnetic gun. The micro -electromagnetic gun designed by Li Jue was 5 grams of solid steel balls.
While installation, Li Yue introduced the basic parameters of the micro -electromagnetic gun while introducing Shi Lei. "Stone Brother, with the energy of the shadow dragon, can only support up to 50 artillery. And each firing, it takes about 1 minute of power.
"
Shi Lei's eyebrows are squeezed together, and it is really a luxurious electromagnetic cannon that consumes 1 minute of stagnation!
"How is power?"
On the workbench, I found a draft paper and handed it to Shi Lei: "The calculated data shows that the solid steel ball with a considerable power.
Shi Lei didn't know the meaning of these data, and said directly: "Little plum, you give me a distance, to what extent the power of micro -electromagnetic guns!"
As the so -called surgery industry has a specialized attack, Shi Lei is a super bull in the computer industry, but in the machinery industry, it has become a rookie cargo SE.
Although Li Yue does not understand the computer's knowledge, he understands that Shi Lei does not understand.
"Brother Stone, based on the calculation formula of the kinetic energy, E12MV2, that is, the kinetic energy is equal to half of the quality multiplied by the quality. The speed of the miniature electromagnetic cannon is 800 meters.
A great number! "After Li Yue's explanation, it was found that Shi Lei was still confused, obviously it was explained!
Shi Lei cough: "Directly, it is equivalent to what it is!"
Li Yue thought for a while, only to explain: "Stone Brother, do you know the M4 Cabers?"
In the previous life, the M4 Kabbin gun was Shi Lei's favorite. Whether it was the SHE hitting speed, or the confirmation of Jing, or the SHE Cheng, it was very excellent.
"Well, I know!" Shi Lei nodded and surprised: "Mu Fei is almost the same as the M4 Cabbam?"
Li Jian nodded, "Yes! M4 Cabba's muzzle's early velocity is 880m seconds, the muzzle kinetic energy is 1645 scorch ears, the bullet weight is slightly lighter than 5 grams. Our miniature electromagnetic cannon is almost the same as the Kablin gun, that is, it is also the kinetic energy.
The power is almost the same! "
After listening to Li Yue's explanation, Shi Lei understood that his previous mistakes about the power of electromagnetic guns. The original power could not only look at the speed. It also depends on the quality of the projectile, and the kinetic energy that was finally combined.
The kinetic energy is energy!
The higher the energy, the greater the destructive power, and the higher the power!
There is another example to explain the power of micro -electromagnetic guns, that is, the famous black star five -fourth -type pistol, the muzzle kinetic energy is only 480 Jiao ear.
After almost understanding the power of micro -electromagnetic guns, Shi Lei finally showed a smile. But Shi Lei raised another doubt. Although he didn't know much about physics and did not know much about the conversion between energy, Shi Lei still knew
One kilowatt time. That is, the one -time electricity is equivalent to many, many scorched ears.
Why does one shot of the electromagnetic gun consume one minute of Shadow Dragon's battery life?
Shi Lei asked his doubts, and Li Guai took out more detailed parameter drawings and explained them 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.
Shadow Dragon uses distributed battery energy supply. A total of five batteries are installed. They are on the four frames of the propeller and the main battery compartment of the cabin. The total capacity of the five electromagnetic batteries reaches 2.2 kilowatt hours.
Each of the four propellers has a power of 300w. The total power of the four propellers reaches 1.2kw, which consumes 1.2 kilowatt hours of electricity per hour.
Shadow Dragon also has on-board computers, ranging radars, and surveillance cameras, which also consume power, adding up to almost 5 million watts, which is 0.5 kilowatt-hours of power per hour.
The total power consumption of Shadow Dragon in one hour is 1.7 kWh, and the total power remaining is 0.5 kWh, which can support about ten minutes of flight time.
The maximum flight range is 80 minutes, which is still quite ideal!
One electromagnetic gun only has 1,600 joules of energy. For the Shadow Dragon, which has nearly 8 million joules of energy, why does it take about 1 minute to reduce the flight range once it fires?
Calculated according to the total energy divided by the total time, approximately 8 million joules of energy are divided by the flight time of approximately 80 minutes, which consumes approximately 100,000 joules per minute.
Is the difference between 100,000 joules and 1,600 joules too big?
In fact, this is not the case. Due to process limitations, material limitations, and structural limitations of the miniaturized electromagnetic gun, the energy conversion efficiency of Lorentz force and electromagnetic effects is very low!
A conversion rate of only 1.6% is not surprising!
After listening to Li Cai's explanation, Shi Lei coughed and asked, "Xiao Lizi, in a word, there is still a lot of room for improvement in the micro electromagnetic gun in the future?"
"Well! You can say that! With the improvement of the technology and craftsmanship we have mastered, better material input, and more advanced frames, our electromagnetic gun will eventually become more and more powerful!" Li Chai was confident.
Full of openings.
Shi Lei clapped his hands and said, "I'm relieved now! Little Li, put this electromagnetic gun on first. I want to 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 mini submachine gun, they all adopt a modular design.
As long as it is standard modular, you only need to load it accordingly and it can be completed in a few minutes!
It took Li Guai seven or eight minutes to install the electromagnetic gun and the shadow dragon together. He also checked it once and confirmed that there was no problem before he said to Shi Lei: "Brother Shitou, there is no problem!"
Shi Lei checked the battery information fed back by the ech system. There was still 76% battery left, which could last for more than fifty minutes of flight.
As the shadow dragon took off, Shi Lei controlled the shadow dragon to fly out of the living room and towards the outside world.
Li Chai said nervously: "Brother Shitou, the electromagnetic gun is very powerful. What are you going to use to test its power?".
