Metropolis: King of Hackers!

Chu Hao is not quite sure about the meaning of these data, and directly said: "Little Lizi, you give me a distance explanation, to what extent the power of the miniature electromagnetic gun has reached!"

As the saying goes, Chu Hao specializes in technology. Chu Hao is a super talent in the computer industry, but in the machinery industry, he has become a rookie.

Although Li Guai does not understand computer knowledge, he understands what Chu Hao does not understand.

"Brother Chu Hao, according to the calculation formula of kinetic energy, E=1/2MV2, that is, kinetic energy is equal to half of the mass multiplied by the speed square. The speed of the miniature electromagnetic gun is 800 meters per second, and the weight of the 23 solid projectile is 0.005kg. The kinetic energy is 1600 joules. This is an amazing number!" After Li guessed the explanation, he found that Chu Hao was still in a confused state.

Of course it was explained in vain!

Chu Hao coughed: "Just say, it's as powerful as something!"

Guess Li thought for a while before giving an example: "Brother Chu Hao, do you know the M4 carbine?"

In the previous life, the M4 carbine was Chu Hao's favorite. It was excellent in shooting speed, accuracy, or range.

"Well, I know!" Chu Hao nodded, surprised: "Could it be as powerful as the M4 carbine?"

Li Guai nodded, "That's right! The muzzle velocity of the M4 carbine is 880M/s, the muzzle kinetic energy is 1645 joules, and the bullet weight is slightly lighter than 5 grams. Our miniature electromagnetic gun is almost the same as a carbine in terms of kinetic energy. Just the same in power!

After listening to Li Guai's explanation, Chu Hao realized his previous mistakes about the power of the electromagnetic gun. It turned out that power cannot only be based on speed. It also depends on the quality of the projectile 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, Chu Hao finally smiled. But Chu Hao raised another doubt. Although he didn't know much about physics and the knowledge of energy conversion, Chu Hao still knew about one kilowatt hour of electricity. That is, one kilowatt of electricity is equal to many, many joules.

Why does it take one minute of Shadow Dragon's battery life for a single shot of the electromagnetic cannon?

Chu Hao asked his doubts, and Li Guai took out a more detailed parameter drawing and explained it to Chu Hao.

According to the conversion of energy. One kilowatt-hour is equivalent to 3.6 million joules of electricity.

Shadow Dragon uses distributed battery energy supply. A total of five batteries are installed. They are the four frames of the propeller and the main battery compartment of the engine room. The total capacity of five electromagnets has reached the level of 2.2 kilowatt-hours.

There are four propellers, each of which has a power of 300W. The four propellers add up to 1.2kW, which consumes 1.2 kilowatt-hours of electricity in one hour.

The Shadow Dragon also has an onboard computer. Ranging radars, surveillance cameras, these 243 also require power consumption, which add up to almost 500W. That is, 0.5 kilowatt-hours of electricity per hour.

The total power consumed by the Shadow Dragon in one hour is 1.7 kWh, and the total power is still 0.5 kWh, which can support more than ten minutes of flight time.

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

An electromagnetic gun has only 1600 joules of energy. For a shadow dragon with nearly 8 million joules of energy, why does it take about 1 minute to reduce the range of one shot?

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