As the core of modern maritime forces, aircraft carriers have a powerful strike force and a strategic role. On the aircraft carrier, there are many key equipment, tools, and components that are expensive, such as rivets on the deck, and some cars worth more than 100,000 yuan. There is also a must-have tool--- blocking cable, which is even more valuable. This is the most expensive rope on the aircraft carrier, one is worth 10 million, and only China, the United States, Russia and the United Kingdom have the core technology. Why is a seemingly ordinary rope so expensive?
The birth of aircraft carriers can be traced back to World War II, when, with the rapid development of aviation technology, the Navy needed a platform capable of delivering powerful strikes at sea. The aircraft carrier came into being and became a first-class system capable of carrying a large number of carrier-based aircraft to the theater of operations and carrying out long-range strikes. The power of the aircraft carrier is mainly reflected in the attack capabilities of its carrier-based aircraft, which can quickly maneuver and project strength to strike at enemy targets.
In terms of battlefield applications, aircraft carriers have a variety of combat methods. First of all, it can carry out long-range strikes by carrier-based aircraft. Carrier-based aircraft can perform a variety of tasks, including maritime patrols, air interception, land attacks, and more. Secondly, aircraft carriers can also fight through their own ** through naval guns, missile systems, etc. In addition, the aircraft carrier can also be used as a command platform to carry out combat operations in coordination with other ** and carrier-based aircraft. The presence of aircraft carriers can change the battlefield pattern and play an important role in protecting the country's maritime borders, carrying out long-range strikes, and maintaining regional stability.
In the process of take-off and landing of carrier-based aircraft on an aircraft carrier, the arresting cable is one of the most important tools. A blocking cable is a special kind of rope that is used to achieve a rapid deceleration process of a carrier-based aircraft from a flying state to a complete stop. When a carrier-based aircraft lands on an aircraft carrier, it is necessary to quickly stop the aircraft by means of a blocking cable to ensure safety and not to fall into the sea. This is a highly technical and dangerous operation that requires the arrestor cable to be characterized by high strength, abrasion resistance and high temperature resistance.
Arrest cables are expensive because the manufacturing process is complex and demanding, requiring the use of special materials for manufacturing. To ensure the strength and durability of the arresting cable, high-strength alloy steel wire and coating technology are often employed. Such materials and processes make the arrest cable tensile and anti-abrasion, anti-abrasion and corrosion resistant, and can work well in harsh offshore environments. Generally, it needs to withstand a tensile force of 100 tons.
Due to the usually long service life of aircraft carriers, each aircraft carrier needs to be replaced several times during its service. In addition, the huge impact and friction that the arresting cable is subjected to during the take-off and landing of the carrier-based aircraft will also cause its rapid wear. Therefore, the requirements for the arresting cable are very high and must undergo strict quality inspection and maintenance to ensure the normal operation of the aircraft carrier and the safety of the pilot. Generally, the life of the blocking cable is about 100 times, and the cost of use is 100,000 yuan.
In 1997, France built the only nuclear aircraft carrier "Charles de Gaulle" other than the United States, but it lacked a blocking cable, and finally had to buy it from the United States, spending 1.5 million US dollars, equivalent to more than 10 million yuan. After entering the 21st century, China also had its first aircraft carrier "Liaoning", which wanted to buy a blocking cable from Russia, but its quality and craftsmanship could not meet our needs, and later it was purchased from the United States, and the other party offered $10 million a **. This obviously wants to slaughter us.
Eventually, China decided it was on its own, so it immediately invested resources and began building a process blocker. You must know that the flight speed of the carrier-based aircraft is very fast, reaching 1,000 kilometers per hour, and if you want to be fast when landing, it will be zero, then you must block the cable to withstand the strong impact force, so it must have at least a tensile force of more than 100 tons. And it must also have enough abrasion resistance and resilience. In the end, after hard work, in 2012, our blocking cable handed over a satisfactory answer, on the Liaoning ship, only 2 seconds after the carrier-based aircraft landed, the fighter plane completely stopped. At this point, China has once again broken the technological monopoly of the West.
