The huge aircraft carrier is currently the giant at sea, and the propeller that pushes the aircraft carrier forward is so large that it is beyond people's imagination, and the 110,000-ton aircraft carrier propeller is as big as a few floors, and such a huge equipment can be manufactured. China's Zhenjiang has the answer and has successfully built the world's largest propeller.
At present, the mainland has built three aircraft carriers to build aircraft carriers, and the rapid development of technology has also aroused the attention of the world.
If the construction of an aircraft carrier is regarded as an overall project, it is like building a building, which has many construction contents and is composed of different construction parts.
How big is the propeller of a 110,000-ton aircraft carrier?
The super-large propeller developed by the mainland Zhenjiang China Shipbuilding is huge, with a diameter of 10 meters, which is equivalent to the height of a three-story ordinary residential building, and when rotating at full speed, this diameter is equivalent to twice the propeller of the American aircraft carrier, providing a strong guarantee for the high-speed navigation of the mainland aircraft carrier.
The huge propeller built by Zhenjiang Zhongchuan can reach 600-800 revolutions per minute, which will form a huge whirlpool in the seawater, and when the propeller of the aircraft carrier rotates, it will not only form a huge thrust, but also produce obvious sound, so the manufacturing of propellers also requires high-tech composite materials to reduce noise.
Not only that, the difficulty of building an aircraft carrier propeller is very large, and it is conceivable that it is necessary to soak in seawater for a long time, and provide huge propulsion assistance for an aircraft carrier of about 100,000 tons with the power system, and constantly rotate at high speed, which is a great challenge to the stability and high strength of the propeller.
Due to the corrosive effect of the high salinity of the seawater, the huge reaction force that the propeller is subjected to when it rotates, and the long hours of sailing in the seawater, these put forward very high and strict standards for the manufacture of propellers.
The material selected for the construction of the helix angle is currently used copper with special metals such as zinc, tin, aluminum, manganese, and silicon, and titanium alloys based on titanium and other metals added.
After these metals are processed in a special ratio, they are not only lightweight, but also highly corrosion-resistant, and have high strength and toughness, which are exceptionally strong, and can be completed when the aircraft carrier is sailing at full speed, as well as the impact of wind and waves, and the bearing capacity of the propeller.
The construction cost of titanium alloy is very high, and the processing requirements are very many, and the difficulty is very large, and it can only be built using a super-large CNC stamping process, but the advantages of titanium alloy are also obvious, which can reduce the reflection section of the radar, help the aircraft carrier achieve better stealth function, and can also reduce the weight of the aircraft carrier by virtue of its lighter density, so as to promote the navigation of the aircraft carrier more smoothly and quickly.
If only from the appearance, the structure of the propeller is very simple, only a few huge blades, like the appearance of an electric fan, but the real propeller, the existence of high technology inside, is beyond people's imagination of complexity, the structure of the propeller includes a variety of scientific and technological factors to propel the efficiency, noise ratio vibration frequency and hydrodynamic force and water flow into the blade angle and speed calculation, etc., these are related to whether the aircraft carrier can be promoted, to achieve flexible navigation, steering, but also related to the navigation safety of the aircraft carrier, So the propeller, which seems to be inconspicuous, is actually the core component.
Of course, any part of the whole is an indispensable part, but the propeller is related to the aircraft carrier moving on the sea surface, the most direct thruster.
At present, the 110,000-ton huge propeller built by the mainland has set a global record, and it is also the largest propeller in the world, which is equivalent to twice the size of the propeller of the US aircraft carrier.
The success of the construction of the huge propeller also means that China is now able to increase the displacement of the aircraft carrier and expand the size of the aircraft carrier, so as to achieve the effect of increasing the ability of the aircraft carrier to carry weapons and the overall strengthening of combat strength.
Zhenjiang CSSC was able to develop a huge propeller that set a world record, breaking the long-term monopoly of the West on this technology, realizing the mainland's independent patent technology research and development, and to a certain extent, realizing scientific and technological innovation.
At present, Continental's scientific research team is still making unremitting efforts to continuously optimize the propeller technology in terms of power transmission, improving efficiency, converting cutting water flow into thrust, and preventing cavitation. At the same time, greater progress has been made in the anti-corrosion technology of paddles.
It is precisely because of the unremitting progress of the mainland scientific research team to build better aircraft carriers for the mainland, constantly break through the bottleneck of research and development, ensure the safety of the construction and use of aircraft carriers, and provide technical support for the mainland navy to build a more powerful combat power.
Judging from the current situation, the mainland's propeller construction technology has reached the world's advanced level, which also provides a great confidence guarantee for the mainland to carry out the new aircraft carrier construction plan in the future.
