The significance of the Jiaolong manned submarine
The Jiaolong Manned Submersible was of great significance in many aspects. First of all, it was China's first self-designed, self-integrated deep-sea manned submarine, marking a major breakthrough in China's deep-sea exploration technology. China became the fifth country after the United States, France, Russia, and Japan to master deep-sea manned diving technology, announcing that China had entered a new era of manned diving. Secondly, Dragon could build a stable and reliable platform for scientists to explore the deep sea and study the deep sea. It had many abilities to explore the ocean, such as seabed operations and positioning systems, which was helpful for scientific research related to the deep sea. Moreover, the Jiaolong had reached a depth of 7062 meters, setting the world's record for the largest diving depth of similar operational submarines. This achievement reflected China's strength in the field of marine science and technology. It also meant that China had the ability to carry out operations in more than 99% of the world's oceans. It had great and far-reaching significance for further understanding the ocean, developing the ocean, protecting the ocean, and promoting the peaceful use of international seabed resources by mankind.

Jiaolong Manned Submersible Encyclopedia
The Jiaolong manned submarine was China's first self-designed and self-integrated deep-sea manned submarine. In 2002, the relevant research and development work was started. The assembly was completed on September 1, 2007. In August 2009, the 1000-meter and 3000-meter sea trials were carried out successively. On June 27, 2012, the diving depth reached 7062 meters, creating the world's record for the largest diving depth of similar operational submarines. China became the fifth country after the United States, France, Russia and Japan to master the deep diving technology, opening a new era of China's manned deep diving. On May 28,2024, the "Deep Sea No. 1" scientific research ship carrying it returned to the dock of the National Deep Sea Base in Qing Dao, marking the successful completion of China's first Atlantic Ocean manned deep diving scientific expedition mission. It was 8.2 meters long, 3.0 meters wide, and 3.4 meters high. Its empty weight did not exceed 22 tons, its maximum load was 240 kilograms, its maximum speed was 25 nautical miles per hour, and its cruising speed was 1 nautical mile per hour. It carried three people, and its designed maximum diving depth was 7000 meters. It could move freely in the sea area that occupied 99.8% of the world's ocean area. The Jiaolong Manned Submersible System consisted of the main body system, the surface support system, the mothership modification system, and the submarine training system. It had three major technological breakthroughs: near-bottom automatic navigation, deep-sea hovering positioning, and high-speed underwater sound communication. It could build a stable and reliable platform for scientists to explore and study the deep sea. The novel "Flood Dragon" is equally exciting. Everyone is welcome to click and read it!
Disadvantages of the Jiaolong Manned Submersible
Flood Dragon was originally positioned to explore the deep sea and did not have any attack capabilities. Its power system could only keep the submarine moving at a low speed underwater, but it could not provide high-speed underwater navigation. It was too large and there were large irregular objects outside the ship. The noise when it sailed underwater was relatively loud, and it was easy to be discovered by the anti-submarine department of the enemy aircraft carrier battle group and suffer from long-range and near-range anti-submarine attacks. It was too small to even carry a light torpedo safely. It was not aggressive. In addition, Dragon needed a long time to prepare for each dive, and it couldn't dock and rescue people.

The problem solved by the Jiaolong submarine
Dragon solved the following problems: 1. [Pressure resistance problem: The Dragon needs to overcome the huge water pressure on the seabed. For example, the water pressure in the Mariana Trench is more than 1000 times the standard atmospheric pressure.] China successfully resisted ultra-high pressure by using a 70-millimeter-thick titanium alloy shell, and the three observation windows made of pure glass on its structure could also withstand water pressure. This showed that China's technology in the waterproof aspect of submarines had reached the forefront of the world. 2. [The difficulty of controlling the rise and fall of a submarine: It must be able to sink and rise smoothly.] Dragon solved this problem with the help of ballasting iron. The ballasting iron began to provide negative buoyancy for the submarine to sink. After reaching a certain depth, it threw away part of the ballasting iron to make its specific gravity close to the density of seawater, reducing the working pressure of the propeller. After the operation was completed, it threw away the ballasting iron again to obtain positive buoyancy. 3. ** Communication problem **: Because electromagnetic waves are seriously weakened underwater, the submarine needs to transmit information using sonar, but there is a problem in extracting sound transmission signals in different seawater environments. Dragon's domestic sound system solved this problem. Its sonar could accurately send and identify signals, and it could also explore the surrounding fine terrain. At the same time, the domestic ultra-short baseline positioning system could provide underwater positioning and navigation services, and the equipment could broadcast the exploration process. 4. ** Life support problem **: Like a space capsule, a deep-sea vehicle needs water, food, and a circulatory system to ensure that the submariners can operate normally underwater. There were two oxygen supply systems inside Dragon, which could guarantee the safety of three people for 84 hours. The novel "Flood Dragon" is equally exciting.
