Chapter 82: Electromagnetic Catapult

Dr. Ma brought more than a dozen researchers and engineers from the Institute of Maritime Research to the Institute of Electromagnetic Research of Galaxy Technology.

"Dr. Ma is welcome." Huang Haojie smiled and shook hands with Academician Ma.

"Haojie, don't be polite, I'm here to learn from the experience this time." Dr. Ma said with a smile.

"Come inside, please."

Huang Haojie took Dr. Ma and his party to the Institute of Electromagnetism.

Galaxy Technology has recently carried out a front-of-the-road upgrade of all its laboratories.

The Institute of Materials, the Institute of Batteries, the Institute of Superconductors, the Institute of Electromagnetism, the Institute of Electric Vehicles, the Institute of Electrical Machinery, the Institute of Lasers, the Institute of Wind Energy, the Institute of Solar Energy, and the Institute of Airship were established respectively.

and the Institute for Social Research, which is responsible for researching the market, the frontier of science and technology, policy influence, etc., mainly for Huang Haojie as a think tank.

Among the large test sites of the Institute of Electromagnetism.

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 catapults.

The electromagnetic catapult is the latest generation of aircraft carrier special aircraft catapult being developed by the navies of many countries such as Mi Lijia, John and Dongtang.

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

In the same way as the maglev train, the electromagnetic catapult uses a linear electric motor as the power source, which is the biggest difference between it and the traditional steam catapult.

The advantage of an electromagnetic catapult is that it is safer and more reliable, because compared to a steam catapult, the acceleration process is more uniform and the structural damage to the aircraft carrier is also less.

Other advantages of electromagnetic catapults are the low weight of the equipment, the moderate cost of construction and the low maintenance cost. Conversely, electromagnetic catapults can catapult heavier aircraft than conventional catapults.

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 electromagnetic catapults is that if the power system or nuclear reactor of the aircraft carrier fails, the entire system will not work.

In addition, since the catapult needs to consume a lot of electricity, the four sets of generator sets that serve as its energy source will take up a considerable amount of 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 precision control system.

"Dr. Ma, I think we can change the forced energy storage device to a Raytheon battery." Huang Haojie looked at the information brought by Dr. Ma and suddenly proposed.

Dr. Ma thought for a moment, then asked:

"But the power of the electromagnetic catapult in this way may not be enough, after all, four electromagnetic catapults need 16,000 kilowatts of power, and the battery is simply not enough to provide such a huge amount of electrical energy in an instant."

Huang Haojie explained with a smile:

"No, if the magnetic crystal is plated on the pulse generator and the aircraft towbar, I estimate that the electrical energy consumption can be reduced by 60~70%.

That is to say, at this time, the four electromagnetic catapults do not need 16,000 kilowatts of power, only about 5,600 kilowatts of power. ”

Syllable! Dr. Ma clapped his hands suddenly, and his eyes lit up.

"What you said is not wrong, if you can really reduce the power consumption by 50~60%, you can really use batteries as energy storage devices."

Dr. Ma hurriedly grabbed a kind of scratch paper and calculated.

Assuming that the energy consumption of the electromagnetic catapult is reduced by 60% after magnetic crystal plating, the total power of the four electromagnetic catapults will be 6400 kilowatts.

The military Thor battery is 500 watt-hours per kilogram, which requires 12,800 kg of Thor battery, which is 12.8 tons of Thor battery.

And more than a dozen tons is just a drizzle for a battleship, especially for a carrier who is tens of thousands of tons at every turn.

"Let's give it a try." Dr. Ma said excitedly.

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

If it's a nuclear-powered aviation mother, it's easy to say, a non-nuclear-powered aviation mother is already short-legged, and if you add the energy consumption of the electromagnetic catapult, it will be even shorter-legged.

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 range can reach 7,000 nautical miles, that is, about 13,000 kilometers.

At a high speed of 30 knots, the maximum cruising range is only 3,850 nautical miles, or about 7,000 kilometers.

After all, not only the electromagnetic catapult needs electricity, but also radar, laser, and the life of the crew all need to consume electricity.

Huang Haojie took the people from the Galaxy Technology Electromagnetic Research Institute, and also followed Dr. Ma and others to make this improved version of the electromagnetic catapult.

The main reason why he is so interested is the electromagnetic catapult, which is in fact a monkey version of the mass projector.

Or rather, the pre-technology of the mass projector.

After more than half a month, with the support of Huang Haojie, Dr. Ma finally created 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 the test, Huang Haojie also built five large stainless steel aircraft models, weighing 10~50 tons respectively.

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

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

"Okay, I've checked it all here, and there's no problem."

Soon, a model of about 10 tons was dragged onto the towbar of the electromagnetic catapult.

"Let's go!"

Sou...... Touch......

In an instant, the model was ejected by the electromagnetic catapult, but fortunately, Huang Haojie had already prepared to set up several layers of interception nets more than 100 meters away from the end of the catapult.

Dr. Ma looked at the speedometer on the side, and it was obvious that the speed of the model just now exceeded the expected speed, reaching 112 meters per second, which was obviously not suitable.

After all, the ejection speed of the aircraft is not as fast as possible, if it is a drone, it is okay, but if there is a pilot of the plane like this, the pilot may be finished.

Generally, when catapulting and taking off, the aircraft needs to accelerate from a standstill to a speed of about 270 kilometers per hour (75 meters per second) with the help of a catapult at a distance of less than 100 meters, and this process needs to be completed within 3 seconds, and the pilot can bear at least 4 G of acceleration (equivalent to 4 pressing on his body), and the limit can reach about 5.8G.

"Turn the power down by another 25%."

After a while, the 10-ton model was once again hung on the towbar of the aircraft.

Sou...... Touch......

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

"It's amazing, it's just a perfect electromagnetic catapult with magnetic crystals, it's like being reborn." Dr. Ma stared excitedly at the 79 meters per second displayed on the speedometer.

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

The ejection weight of the magnetocrystalline electromagnetic catapult is 1~50 tons, because the maximum model is only 50 tons, but Dr. Ma calculated that the maximum ejection weight of this electromagnetic catapult should reach about 60 tons.

The ejection speed is 60~224 meters per second, especially when catapulting the drone, because there is no need to worry about the factors affecting the human body, the ejection speed can be increased as much as possible.

The ejection interval is between 30~180 seconds, and the weight of the ejection needs to be seen.

Electricity consumption has been reduced by around 63%.

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

Compared with the steam catapult of 500 to 1,000 tons, it is difficult to adjust the power, and the steam catapult not only has a long interval, but also if the steam catapult works continuously, the power and speed of the fifth catapult will be significantly reduced.

Obviously, this magnetocrystalline electromagnetic catapult is already in actual combat.

That's the power of materials, and when the material meets the requirements, the technology often becomes simpler.
