When talking about "maintenance", what do you think of first? Probably many friends will think of driving their car to a 4S store for maintenance. In fact, not only cars, but also aircraft carriers need maintenance. The first domestically produced aircraft carrier has just completed its "maintenance" recently and has begun to re-launch with a brand-new appearance. So what has been done for the first maintenance of the domestic aircraft carrier this time? What impact will it have on aircraft carriers? Let’s take a look below.
According to public media reports, we saw that the domestic Shandong ship has completed its first "4S store" maintenance and is moving out of the dock. Of course, this "4S store" is not an ordinary place, but Dalian Shipyard . The first domestic 901 comprehensive supply ship has also arrived at the shipyard. During the restorative training after completing maintenance, the two ships may be matched again. In fact, the official name of this "maintenance" is: the first planned availability improvement maintenance. As can be seen from the name, this is a planned regular maintenance and improvement plan.
Judging from the pictures, the Shandong ship that has completed maintenance is indeed brand new. It is not an exaggeration to say that it has just been launched into the water. So why is there such a big change? This is mainly due to the content of the first maintenance, which includes the re-paving of the deck coating. Simply put, it means re-paving the upper take-off deck of the carrier-based aircraft with a high-temperature, salt-corrosion and anti-rust coating to ensure that the carrier-based aircraft has An optimal environment for takeoff. Re-coating will also make it more cost-effective, just like painting the road black and then marking the sidewalk, so it will indeed look brand new. Of course, some military fans will ask, just 2 years after the Shandong ship entered the fleet, does it mean that its deck coating is not durable?
In fact, this is not the case. As long as the carrier-based aircraft takes off and lands, there will be wear and tear, and regular maintenance is to keep the aircraft carrier in the best condition. It is worth noting that as a new ship, in the process of forming combat effectiveness, the Shandong ship will inevitably conduct high-intensity take-off training, including night take-off and maximum sortie take-off, etc., so the wear and tear will inevitably be greater, and this maintenance After that, perhaps the Shandong ship will develop complete combat capabilities, which is very worth looking forward to.
Another important step in maintenance is cleaning and painting the bottom of the ship. This is mainly for the lower part of the ship and the part below the water. In fact, this part is difficult to see during normal navigation and parking, even with a bright appearance. Beautiful ships often need to be cleaned after a period of operation below the waterline. Take American aircraft carriers as an example. During the maintenance and overhaul process, a large number of marine shellfish and barnacles often adhere to the bottom, which is very harmful to the bottom of the ship.
A large amount of shellfish accumulated over a long period of time will increase the weight of the ship and affect its performance such as rapid turning and speed. The barnacles themselves also secrete corrosive mucus, which can even cause serious problems such as water seepage at the bottom of the ship for a long time. Moreover, unlike the hull, the bottom of the ship is immersed in highly corrosive seawater for a long time, and the damage is more obvious.
Therefore, in addition to cleaning up the numerous accumulations on the bottom of the ship in the dock, the Shandong ship will also be repainted with a layer of red anti-rust paint . In this way, the maintained Shandong ship will be used in a brand new state, which can effectively maintain the aircraft carrier. service life, greatly improving the ship's continuous combat capability. It is also worth mentioning that after having a lot of experience in using the Liaoning ship aircraft carrier, the Shandong ship also made some small improvements, such as some small welded bosses next to the deck, which may be due to the experience of using the previous aircraft carrier. , this time the Shandong ship seems to have been installed at the same location during maintenance. It seems that there are still some minor improvements after docking.
Generally speaking, this planned regular maintenance will be carried out according to time. In addition, overhaul and maintenance will be carried out after a certain number of years, etc. Of course, the overhaul time of a conventionally powered aircraft carrier will be relatively shorter, while a nuclear-powered aircraft carrier will require a longer period of overhaul and maintenance to ensure the normal operation of related equipment.With three aircraft carriers in the country, and even more aircraft carriers in the future, docking maintenance of related ships will also be a common thing for everyone. In order to ensure that after one aircraft carrier is docked, there will still be other aircraft carriers to take over its tasks and maintain the overall With the level of combat power, it is also imperative to build multiple aircraft carriers. The structure of one aircraft carrier in port, one for dock maintenance, and one for performing tasks will become the norm.
