Galactic Tech Empire

Chapter 81 Electromagnetic Ejection
Dr. Ma brought more than a dozen researchers and engineers from the Sea Research Institute to the Electromagnetic Research Institute of Yinhe Technology.

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

"Don't be polite, hero, I'm also here to learn the scriptures this time." Dr. Ma said with a smile.

"Come inside please."

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

Galaxy Technology has recently carried out previous upgrades to all 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 Electric Machines, the Institute of Lasers, the Institute of Wind Energy, the Institute of Solar Energy, and the Institute of Airships were respectively established.

And the Social Research Institute, which is responsible for market research, technological frontiers, policy impact, etc., 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, which is used for the effect of electromagnetic catapults.

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

At present, only the Milijia Navy has publicly announced the successful development 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 the 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 the structural damage to the aircraft carrier is also less.

Other advantages of electromagnetic catapults are the low weight of equipment, moderate cost and low maintenance cost.Conversely, electromagnetic catapults can launch 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 the electromagnetic catapult is that once the aircraft carrier's electrical system or nuclear reactor fails, the entire system will not be able to operate.

In addition, since the catapult needs to consume a large amount of electricity, four sets of generator sets as its energy source will take up a 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 replace the forced energy storage device with Thor batteries." Huang Junjie looked at the materials brought by Dr. Ma and suddenly suggested.

Dr. Ma thought for a while, and then asked:
"But the power of the electromagnetic catapults is probably not enough. After all, four electromagnetic catapults need 1.6 kilowatts of power, and the battery is simply not enough to provide such a huge amount of power in an instant."

Huang Haojie explained with a smile:
"No, if you put magnetite on pulse generators and aircraft tow bars, I estimate that you can reduce power consumption by 60-70%.

That is to say, at this time, the four electromagnetic catapults do not need 1.6 kilowatts of power, but only about 0.56 kilowatts of power. "

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

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

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

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

The military Raytheon battery is 500 watt-hours per kilogram, so 12800 kilograms of Raytheon batteries are needed, which is 12.8 tons of Raytheon batteries.

For a battleship, more than a dozen tons is nothing more than a drizzle, especially for an aircraft mother that can easily cost tens of thousands of tons.

"Let's try it 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 power consumption by more than half.

If it is a nuclear-powered aircraft mother, it is okay to say that the non-nuclear-powered aircraft mother has short legs, and if the energy consumption of the electromagnetic catapult is added, the legs will be even shorter.

How many nautical miles can Liaodong travel with a full tank of fuel?
According to the known public information: when the Liaodong sails at a speed of 18 knots, the maximum cruising distance can reach 7000 nautical miles, which is about 13000 kilometers.

However, when traveling at a high speed of 30 knots, the maximum cruising distance is only 3850 nautical miles, which is about 7000 kilometers.

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

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

The main reason he was so interested was the electromagnetic catapult, which was in fact the monkey version of the mass catapult.

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

After being busy for half a month, with the support of Huang Haojie, Dr. Ma finally built the first improved electromagnetic catapult.

The guide rail length 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, each weighing 10 to 50 tons.

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

"Dr. Ma, let's start the test!"

"Okay, I checked everything here, and there is no problem."

Soon a model of about 10 tons was dragged onto the aircraft tow bar of the electromagnetic catapult.

"start!"

Whoosh... touch...

In an instant, the model was ejected by the electromagnetic catapult. 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 at the side. Obviously, the speed of the model just now exceeded the expected speed, reaching 112 meters per second. Obviously, this speed is not suitable.

After all, the ejection speed of the aircraft is not as fast as possible. If it is a drone, it is fine, but if the aircraft has a pilot, the pilot may be finished.

Generally, when ejecting and taking off, the aircraft needs to accelerate from rest to a speed of about 100 kilometers per hour (270 meters per second) with the help of the catapult within a distance of less than 75 meters. This process needs to be completed within 3 seconds. The pilot must at least Withstand the acceleration of 4 G (equivalent to 4 yourself pressing on the body), and it can reach about 5.8G in extreme cases.

"Turn down the power by another 25%."

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

Whoosh... touch...

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

"It's great, it's like a perfect electromagnetic catapult with a magnetic crystal, it's like a completely new body." Dr. Ma stared at the 79 meters per second displayed on the speedometer excitedly.

For the next three days, Dr. Ma tested the electromagnetic catapult at the test site. After three days of intensive testing, the data of the improved version of the electromagnetic catapult 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 reach about 60 tons.

The ejection speed is 60-224 meters per second, especially when ejecting drones, 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 Raytheon batteries as forced energy storage devices, the structure and technology become simpler.

Compared with steam catapults with a capacity of [-] to [-] tons, it is difficult to adjust the power. In addition, the interval between steam catapults is not only long, but if the steam catapult works continuously, the power and speed of the fifth catapult will drop significantly.

Obviously, this magnetic crystal electromagnetic catapult is already practical.

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