The 003 aircraft carrier conducted an electromagnetic catapult test at Pudong Airport, and the ejection distance was only more than 100 meters
Recently, a news about China's Type 003 aircraft carrier has caused heated discussions on the Internet. It is reported that when a passenger took off from Pudong Airport, he accidentally photographed the scene of the 003 aircraft carrier conducting an electromagnetic catapult test, and this test was carried out not far from the shore, and the picture was very shocking.
In wartime, heavy aircraft carriers compare the number of aircraft carriers and the take-off efficiency of carrier-based aircraft. The fastest time for the American steam catapult is to take off one plane in 3 minutes, and 2 lanes, that is, 2 planes can take off in 3 minutes. China's electromagnetic catapult is one in 30 seconds, 3 lanes, that is, 3 take-offs in 18 beams. The U.S. military catapulted one plane, and it used 2 to 3 tons of clean water. The aircraft carrier itself purifies about 400 tons of water per day, which can support the take-off and landing of 80 fighters of the entire carrier-based aircraft wing. Regardless of other factors, one US aircraft carrier is equivalent to 160 aircraft a day. China has 60 aircraft carriers, and as long as there is electricity, it can take off and land once in three hours, which is equivalent to 480 fighters in one day. That is, 1 aircraft carrier of China is equivalent to the combat power of 3 aircraft carriers of the US military.

It can be clearly seen from the video that the island of the 003 aircraft carrier is full of officers and soldiers, and a huge electromagnetic catapult equipment is placed on the deck, at the time of the test, a J-15 fighter was ready, and the electromagnetic catapult also made a piercing buzzing sound, and then, the fighter was successfully ejected and took off, however, surprisingly, despite the great power of the electromagnetic catapult, this fighter only flew a short distance and landed on the sea, And the 003 aircraft carrier did not continue with the follow-up tests, and the whole process was very hasty.
The electromagnetic catapult test encountered problems, and the ejection distance was only more than 100 meters
After seeing this scene, some netizens have forwarded comments and questioned the effect of the electromagnetic catapult test, after all, the electromagnetic catapult of an aircraft carrier is usually tested at sea, and the ejection distance of the test must at least have a certain guarantee, but this time the test was carried out not far from the shore, and the ejection distance was only more than 100 meters, such a test effect is indeed incomprehensible.

In fact, this is not the first time that the 003 aircraft carrier has carried out electromagnetic catapult tests, as early as last year, the 003 aircraft carrier has carried out several electromagnetic catapult tests at sea, and the test effect at that time was very successful, the ejection distance can easily reach 400 meters, and the whole test process is very smooth, without any accidents, therefore, this time the electromagnetic catapult test at Pudong Airport undoubtedly gave all passengers a very big surprise.
Possible reasons, there are problems with the deck angles and the design of the ejection trolley
Since the electromagnetic catapult of the 003 aircraft carrier has been successfully tested several times, why did such a problem arise in this test? In fact, in order to ensure the normal operation of the electromagnetic catapult, the angle of the deck and the design of the catapult trolley are very important, and only the cooperation of these two can ensure the successful take-off of the fighter and ensure that the combat mission can be carried out smoothly after takeoff.

It can be clearly seen from the video that this time the electromagnetic catapult test was carried out during the day, and it was not far from the shore, such a test site selection is very strange, it is very likely that the test task of the 003 aircraft carrier is very heavy, there is no way to choose to test at sea like other aircraft carriers, and can only choose to test not far from the shore, and such a test site selection will definitely have a certain impact on the test effect of the electromagnetic catapult.
In addition, there may also be certain problems in the design of the catapult trolley, resulting in the fighter not being able to get enough take-off power, so that the ejection distance is very short, of course, this is only a possibility, and the specific reasons need to be further analyzed and investigated.
The difference between an electromagnetic catapult and a steam catapult, how does it work
I believe that many people do not know much about electromagnetic catapults, in fact, electromagnetic catapults and steam catapults are two different technical routes, and electromagnetic catapults are currently the most advanced carrier-based aircraft catapult methods in the world, and their working principles are very complex.

When the fighter needs to eject and take off, there will be a special operator to control and adjust the ejection process, and then through the control equipment, a certain amount of electric energy will be input to the energy storage equipment, and the energy storage equipment will store this part of the electric energy, and after the machine is ready, the stored electric energy will be released instantaneously, and a very strong electromagnetic field will be formed through the electromagnetic track, so that the fighter will be successfully ejected and taken off.
In contrast, the working principle of the steam catapult is much simpler, it is mainly through the steam injection behind the nozzle of the carrier-based aircraft, which generates a huge thrust, so as to eject the carrier-based aircraft to take off, however, the ejection effect and ejection distance of the steam catapult are greatly limited, and it is also very troublesome to maintain, which is why more and more countries are starting to use electromagnetic catapults.
What exactly went wrong with the electromagnetic catapult of the 003 aircraft carrier
Judging from the current situation, it seems that there are some problems with the electromagnetic catapult of the 003 aircraft carrier, which will lead to a very short ejection distance for this test, so what went wrong?
It is not that the output power is adjustable, but that the ejection thrust curve is adjustable. The output power of steam catapult must also be adjustable, but the steam pressure release process is difficult to adjust, resulting in excessive thrust in the early stage of ejection, and insufficient thrust in the later stage because of low steam pressure. Electromagnetic catapult does not have this problem, and can achieve the initial stage of ejection, the end of the middle stage, and the best thrust can be given.

First of all, it may be because there is a problem with the selection of the test site this time, after all, the test task of the aircraft carrier is very heavy, and there is no way to choose to test at sea like other aircraft carriers, and can only choose to test not far from the shore, such a test site selection will indeed have a certain impact on the test effect of the electromagnetic catapult.
Secondly, there may also be certain problems in the design of the catapult trolley, which cannot provide enough take-off power for the fighter, which will lead to a very short ejection distance, of course, this is only a possibility, and the specific reasons need to be further analyzed and investigated.
No matter what causes the problem of the electromagnetic catapult of the 003 aircraft carrier, I believe that the relevant departments will conduct a serious analysis and investigation of this, find out the problem, and then make corresponding adjustments and optimization, after all, the electromagnetic catapult is a very important part of the aircraft carrier, and its development is of great significance to the combat capability of the aircraft carrier and the ejection ability of the fighter, and the development of electromagnetic catapult technology may also be applied to military aircraft of greater quality in the future, and make greater contributions to the mainland's national defense.
