Galaxy Technology Empire

Dr. Ma brought a dozen researchers and engineers from the Institute of Marine Science and Technology to the Electromagnetic Research Institute of Galaxy Technology.

"Welcome Dr. Ma to come." Huang Haojie smiled and shook hands with Academician Ma.

"Don't be polite, hero. I'm here to learn from you too." Dr. Ma said with a smile.

"Please come inside."

Huang Junjie took Dr. Ma and his party to the Electromagnetic Research Institute.

Galaxy Technology has recently upgraded all its laboratories.

The Materials Research Institute, Battery Research Institute, Superconductor Research Institute, Electromagnetic Research Institute, Electric Vehicle Research Institute, Motor Research Institute, Laser Research Institute, Wind Energy Research Institute, Solar Energy Research Institute, and Airship Research Institute have been established respectively.

As well as the Institute of Social Research, which is responsible for researching the market, technological frontiers, policy impacts, etc., and is mainly used as a think tank for Huang Haojie.

In the large test field of the Electromagnetic Research Institute.

Dr. Ma is busy with a group of people. This time he is experimenting with the magnetic crystal material of Galaxy Technology for the effect of electromagnetic catapult.

The electromagnetic catapult is the latest generation of aircraft carrier-specific aircraft catapults being developed by the navies of Milijia, John and Dongtang and other countries.

At present, only the Milijia Navy has publicly announced that it has successfully developed it and installed it on the Ford-class nuclear-powered aircraft carrier under construction.

The same principle as the maglev train, the electromagnetic catapult uses a linear motor as the power source, which is its biggest difference from the traditional steam catapult.

The advantage of the electromagnetic catapult is that it is safer and more reliable, because compared with the steam catapult, its acceleration process is more uniform and it causes less damage to the structure of the aircraft carrier.

Other advantages of electromagnetic catapults are the equipment's light weight, moderate cost and low maintenance costs. On the contrary, compared with traditional catapults, electromagnetic catapults can eject heavier aircraft.

In addition, the system consumes less fresh water and is more energy efficient.

Of course, since there are advantages, there must also be disadvantages.

The disadvantage of the electromagnetic catapult is that once the aircraft carrier's power system or nuclear reactor fails, the entire system will not operate.

In addition, since the catapult consumes a large amount of electricity, the four sets of generator sets that serve as its energy source will take up considerable space.

The electromagnetic catapult consists of a power supply, a forced energy storage device, a guide rail and a pulse generator, as well as a forced cooling and precise control system.

"Dr. Ma, I think we can switch the forced energy storage device to Thor batteries." Huang Junjie looked at the information Dr. Ma brought and suddenly suggested.

Dr. Ma thought for a while and then asked:

"But I'm afraid the power of the electromagnetic catapult is not enough. After all, four electromagnetic catapults require 16,000 kilowatts of power, and the battery is simply not enough to provide such a huge amount of electrical energy instantly."

Huang Haojie explained with a smile:

"No, if magnetic crystals are plated on pulse generators and aircraft tow bars, I estimate that power consumption can be reduced by 60 to 70%.

In other words, at this time, the four electromagnetic catapults do not need 16,000 kilowatts of power, but only about 0.56 million kilowatts. "

Snapped! Dr. Ma immediately clapped his hands and his eyes lit up.

"You are right. If you can really reduce power consumption by 50 to 60%, you can really use batteries as energy storage devices."

Dr. Ma quickly grabbed a kind of scratch paper and started calculating.

Assuming that after magnetic crystal coating, the energy consumption of the electromagnetic catapult is reduced by 60%, then the total power of the four electromagnetic catapults will be 6,400 kilowatts.

Military Thor batteries are 500 watt-hours per kilogram, which requires 12,800 kilograms of Thor batteries, which is 12.8 tons of Thor batteries.

For a battleship, a dozen tons is just drizzle, especially for an aircraft carrier with tens of thousands of tons.

"We'll give it a try right away," Dr. Ma said excitedly.

After all, Huang Haojie's proposal is very tempting. This is not only a matter of power reduction, but also can reduce the power consumption by more than half.

It would be okay if it was a nuclear-powered aircraft carrier. Non-nuclear-powered aircraft carriers are already short-legged. If the energy consumption of the electromagnetic catapult is added, the legs will be even shorter.

How many nautical miles can the Liaodong travel with a full tank of fuel?

According to known public information: When the Liaodong sails at a speed of 18 knots, the maximum cruising distance can reach 7,000 nautical miles, which is about 13,000 kilometers.

And if traveling at a high speed of 30 knots, the maximum cruising distance is only 3,850 nautical miles, about 7,000 kilometers.

So save as much as you can. After all, not only the electromagnetic catapult on the aircraft mother needs electricity, but also radar, laser, and all aspects of the crew's life need to consume electricity.

Huang Haojie led the people from the Galaxy Technology Electromagnetic Research Institute and followed Dr. Ma and others to develop this improved version of the electromagnetic catapult.

The main reason why he was so interested was the electromagnetic catapult, which was actually the monkey version of the mass projector.

In other words, it is the front-end technology of the mass projector.

After working hard for more than half a month, with Huang Junjie's support, Dr. Ma finally built the first improved version of the electromagnetic catapult.

The length of the guide rail of this electromagnetic catapult is 135 meters, which is the same length as the catapult at the naval training base.

In order to facilitate testing, Huang Haojie also built five large stainless steel aircraft models, weighing 10 to 50 tons respectively.

Because this is a reference to the electromagnetic catapult of the Ford aircraft carrier. The ejection weight limit of the Ford aircraft carrier's electromagnetic catapult is 45 tons, and general steam ejection is less than 35 tons.

"Dr. Ma, let's start testing!"

"Okay, I've checked everything here and there's nothing wrong with it."

Soon a model of about 10 tons was towed to the aircraft tow bar of the electromagnetic catapult.

"start!"

Whoosh...touch...

In an instant, the model was ejected by the electromagnetic catapult. Fortunately, Huang Junjie had already prepared several layers of interception nets more than a hundred meters away from the end of the catapult.

Dr. Ma looked at the speedometer on the side. It was obvious that the speed of the model just now exceeded the expected speed, reaching 112 meters per second. Obviously, this speed was not suitable.

After all, the ejection speed of an aircraft is not as fast as possible. If it is a drone, it is okay, but if an aircraft with a pilot does this, the pilot may be ruined.

Generally, when taking off by ejection, the aircraft needs to accelerate from standstill to a speed of about 270 kilometers per hour (75 meters per second) with the help of the catapult within a distance of less than 100 meters. This process needs to be completed within 3 seconds. The pilot must at least It can withstand an acceleration of 4 G (equivalent to four people pressing on you), and can reach about 5.8G in extreme cases.

"Turn the power down another 25%."

After a while, the 10-ton model was once again hung on the aircraft's tow bar.

Whoosh...touch...

"How?" Huang Junjie turned his head and asked.

"It's great. It's a perfect electromagnetic catapult with the addition of magnetic crystals. It's like a completely different person." Dr. Ma stared excitedly at the 79 meters per second displayed on the speedometer.

For the next three days, Dr. Ma was testing the electromagnetic catapult at the test site. After three days of intensive testing, the improved version of the electromagnetic catapult data was finally presented to everyone.

The ejection weight of the magnetic crystal electromagnetic catapult is 1 to 50 tons. Since the maximum model is only 50 tons, Dr. Ma calculated that the maximum ejection weight of this electromagnetic catapult should be about 60 tons.

The ejection speed is 60 to 224 meters per second. Especially when ejecting a drone, since there is no need to worry about factors affecting the human body, the ejection speed can be increased as much as possible.

The ejection interval is between 30 and 180 seconds, depending on the weight of the ejection.

The power consumption has been reduced by about 63%.

Due to the use of Thor batteries as forced energy storage devices, the structure and technology have become simpler.

Compared with steam catapults, which can easily range from 500 to thousands of tons, it is difficult to adjust the power. In addition, the interval between steam catapults is not only long, but also if the steam catapult works continuously, the ejection force and speed will decrease significantly by the fifth projectile.

Obviously, this magneto-crystalline electromagnetic catapult is already combat-ready.

This is the power of materials. When the materials meet the requirements, the technology often becomes simpler.
