Jiaolong Deep-Sea Submersible
The Jiaolong manned submarine was China's first self-designed and self-integrated deep-sea manned submarine. In 2002, China started its research and development work, and the assembly was completed on September 1, 2007. In August 2009, the 1000-meter and 3000-meter sea trials were carried out. 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 the Jiaolong returned to the dock of the National Deep-Sea Base in Qing Dao after completing China's first Atlantic manned deep diving scientific expedition mission. The Jiaolong was 8.2 meters long, 3.0 meters wide, and 3.4 meters high. It weighed no more than 22 tons, had a maximum load of 240 kilograms, a maximum speed of 25 nautical miles per hour, and a cruising speed of 1 nautical mile per hour. It carried three people and was designed to dive to a maximum depth of 7000 meters. It could move freely in the sea area that occupied 99.8% of the world's ocean. The system included the main body system of the manned submarine, the surface support system, the mother ship modification system, and the submarine training system. There were three major technological breakthroughs: near-bottom automatic navigation, deep-sea hovering positioning, and high-speed underwater sound communication. In terms of structure, it was made of titanium alloy with a thickness of 70 mm to resist ultra-high pressure. There were three observation windows made of pure glass. The design of the ballasting iron was ingenious. It began to provide negative buoyancy to make the submarine sink. When it reached a certain depth, it would throw away part of the ballasting iron to reduce the pressure on the propeller and increase its speed. After the operation was completed, the part that was thrown away would become positive buoyancy to rise. In terms of communication, the domestic sonic system could solve the problem of extracting sound transmission signals caused by different seawater density and temperature. Sonar could accurately send and identify signals and explore the surrounding terrain. There was also a domestic ultra-short baseline positioning system to provide underwater positioning and navigation services. Some equipment could broadcast the exploration process. As for the life support system, there were two sets of oxygen supply systems inside, which could guarantee the safety of three people for 84 hours. The power source was an oil-filled silver-zinc-filled battery with a capacity of more than 110 kWh, which could provide power for dozens of hours. As of August 18, 2024, Jiaolong had completed 300 dive missions in the Pacific Ocean, Indian Ocean, and Atlantic Ocean, carrying a total of 900 people. The novel "Flood Dragon" is equally exciting.
