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 over." Huang Haojie smiled and shook hands with Academician Ma.
"Heroes, don't be polite, I'm here to learn from you too." Dr. Ma said with a smile.
"Please come inside."
Huang Junjie took Dr. Ma and his team to the Electromagnetic Research Institute.
Galaxy Technology has recently upgraded all its laboratories.
The Materials Research Institute, the Battery Research Institute, the Superconductor Research Institute, the Electromagnetic Research Institute, the Electric Vehicle Research Institute, the Motor Research Institute, the Laser Research Institute, the Wind Energy Research Institute, the Solar Energy Research Institute, and the Airship Research Institute were respectively established.
As well as the Institute of Social Research, which is responsible for investigating the impact of cutting-edge market science and technology policies, etc., and is mainly used as a think tank for Huang Haojie.
In the large test field of the Institute of Electromagnetics.
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 many countries, including the Milijia John Kingdom and the Eastern Tang Dynasty.
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 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 it causes less damage to the structure of the aircraft carrier.
Other advantages of electromagnetic catapults are the light weight of the equipment, 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, if 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 is composed of a power supply forced energy storage device 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 the pulse generator and aircraft tow bar, I estimate that the 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."
Bang! Dr. Ma immediately clapped his hands and his eyes lit up.
"You are right. If you can really reduce the 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, so 12,800 kilograms of Thor batteries are needed, which is 12.8 tons of Thor batteries.
For a battleship, a dozen tons is just drizzle, especially for an aircraft carrier that can easily weigh 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. It 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 were 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 3850 nautical miles, which is about 7000 kilometers.
So if you can save, try to save as much as possible. After all, not only the electromagnetic catapult on the aircraft carrier needs electricity, but also all aspects of the life of the radar and laser crew members need to consume electricity.
Huang Haojie led the people from the Galaxy Science and Technology Electromagnetic Research Institute and followed Dr. Ma and others to develop this improved version of the electromagnetic catapult.
The main reason why he is so interested is the electromagnetic catapult, which is 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 USS Ford aircraft carrier. The ejection weight limit of the electromagnetic catapult of the Ford aircraft carrier is 45 tons. Generally, 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!"
swish
In an instant, the model was ejected by the electromagnetic catapult. Fortunately, Huang Haojie had already prepared 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. 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 5.8 g in extreme cases.
"Turn down the power by 25."
After a while, the 10-ton model was once again hung on the aircraft's tow bar.

"How?" Huang Junjie turned around and asked.
"It's great. It's a perfect electromagnetic catapult with the addition of magnetic crystals. It's completely transformed." 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 has 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, you can increase the ejection speed as much as possible because there is no need to worry about factors affecting the human body.
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 often range from 500 to thousands of tons, it is difficult to adjust the power. In addition, not only does the interval between steam catapults be long, but if the steam catapult works continuously, the ejection force and speed will decrease significantly by the fifth projectile.
Obviously, this magnetocrystalline electromagnetic catapult is already practical.
This is the power of materials. When the materials meet the requirements, the technology often becomes simpler.
