Where is the electromagnetic ejection of the Fujian ship?

As the first ejection aircraft carrier designed and built in China, the Fujian ship adopts a flat -headed long flight deck to configure electromagnetic ejection and blocking device.

The electromagnetic jets equipped by Fujian ship have become the focus of attention from the outside world. How big is its advantage?

The original title was "The electromagnetic ejection used by the Fujian ship. How big is the advantage? ", Does not mean looking at the view of the think tank.

The carrier -based aircraft take -off method of the carrier can be divided into two categories: slippery take -off and ejection take -off. Choose different carrier -based aircraft and corresponding take -off and landing methods to largely determine the combat effectiveness of the carrier.

For light aircraft carriers, it is not only a feasible way to take off with a sliding deck, but also must also introduce a carrier -based fighter with a short -range take -off/vertical landing capability simultaneously. This has also led to today and South Korea to promote light aircraft carrier programs, and F-35B fighters must be introduced from the United States.

The British "Queen Elizabeth" -class aircraft carrier uses a skid to take off

In contrast, the choice of large and medium -sized aircraft carriers is much larger. The US "Nimitz" class, Ford -class super carrier and French "Da Gogh" use the standard "ejection take -off+blocking landing" mode, which can be equipped with a variety of conventional fixed -wing aircraft. Russia's "Kuznetsov" and India's "Super Rich King" and "Vikrant" aircraft carrier chose the "Slide take -off+blocking landing" mode, but it can only take off and land fixed wing fighters, but not cannot Take off fixed wing early warning aircraft. The British "Queen Elizabeth"-class aircraft carrier is even more unique. He chose the F-35B fighter aircraft to cooperate with the "Slide and take off+vertical landing" mode.

Military experts said that the benefits of slippery -style take -off are that the maintenance costs of aircraft carriers can be reduced and the structure of the aircraft carrier can be simplified. However, the sliding deck restricts the take -off weight of the fighter, resulting in the combat radius, stagnation time and weapon carrying volume of the fighter. At the same time, special aircraft, including early warning aircraft, cannot take off using the skidial deck, causing the aircraft carrier to lose long -distance air warning detection capabilities during the long sea of ​​war. In addition, the sliding deck will occupy the pillar space of the aircraft carrier flying deck, causing the parking space and scheduling of carrier -based aircraft to be affected.

In contrast, the advantage of ejection take -off is very obvious. The first is that the fighter can take off with fuel and ammunition, which is equivalent to directly improving the combat capabilities of the fighter. At the same time, the ejection take -off can also allow the aircraft carrier to have the ability to carry a fixed -wing carrier -based early warning aircraft, which greatly improves the early warning detection of aircraft carriers and the ability to ensure and scheduling the carrier -based aircraft.

The US "Ford" aircraft carrier installed 4 electromagnetic projectiles

However, the ejection take -off requires a very high -specific ejection device. The US "Nimitz" and the French "Damage" use steam projectiles, and its manufacturing processing technology is in the hands of the United States. The currently updated generation of the ejection device is an electromagnetic ejaculation. According to experts, electromagnetic rebounders have great advantages over steam projectiles. For example, digital management and monitoring can be performed, and aircraft of different quality can flexibly control the control of ejection force, the weight and capacity of electromagnetic population ships are low. Maintenance is relatively simple. According to the test results of the US Navy, the 4 steam ejaculation of the "Nimitz" -class aircraft carrier can usually ensure a maximum ejection take -off of 200 times a day, and the 4 electromagnetic jets of the "Ford" increase this number to 270 times , Greatly improved the displacement efficiency of carrier carrier aircraft.

In addition, the electromagnetic ejaculation can also easily control the ejection force. It is as large as transport aircraft and early warning aircraft. Various models of drones can take off from the aircraft carrier by ejection, making the aircraft carrier's combat mode more flexible. However, the development of electromagnetic jets is even more difficult to develop. The "Ford" has failed to form a combat effectiveness for several years. One of the main reasons is that the failure rate of electromagnetic jets is high.
