Type 096 Propulsion System.
The submarine is one of the important equipment of the modern navy. Because the seawater has a blocking effect on electromagnetic waves, general radar detection cannot be effective. At present, most countries in the world use sonar to detect submarines, which means that submarines have higher and higher requirements for silence.
However, traditional naval ships use propeller propulsion. Although this method of propulsion is more efficient, when advances, a large number of bubbles will be generated between the propeller and the sea, causing a cavitation effect. The ship’s propellers have a corrosive effect and also produce loud noise; and the mechanical structure of the propeller propulsion system is complicated, and the friction between the bearing and the hull will also produce loud noise, which seriously affects the submarine The silent performance makes it easier to be detected by the enemy's sonar.
So, in order to improve the quiet performance of submarines, pump jet propulsion was developed. The earliest pump-jet propulsion system was developed by the UK in the 1980s and was installed on its own nuclear submarine for testing. The results showed that it can effectively reduce the submarine's noise, which has also been valued by countries all over the world.
Traditional propeller propulsion is well understood by everyone, and pump jet propulsion is similar to putting a shell on the tip of the propeller. The advantage of this is that it can effectively reduce the cavitation effect and reduce the noise level of the submarine. Therefore, the pump jet propulsion system has also been developed as an advanced submarine technology by various countries.
Nevertheless, pump-jet propulsion still requires propeller drive, and the noise in bearings and mechanical structure is still very loud. Is there a solution?
Of course, the team led by Academician Ma Weiming, an expert on military equipment in my country, developed the world's first shaftless pump-jet propulsion system. It replaces the traditional bearing propeller with a ring and drives it by a motor. The advantage of this is that it can effectively reduce the proportion of the mechanical structure in the propulsion system.And it got rid of the structure of the transmission shaft that both traditional propellers and early pump-jet propulsion had. Shaftless pump-jet propulsion also uses electric energy as a power source, which indirectly reduces the internal mechanical structure of the submarine and greatly reduces The noise level of the submarine while it is sailing.
The shaftless pump-jet propulsion system is relatively the most advanced in the world. Whether it is a nuclear submarine or a conventional power submarine, as long as the shaftless pump-jet propulsion is used, it can truly become silent." "Oceanic Black Hole" is of great significance to my country from the perspective of equipment development and from a strategic perspective.
And my country’s academician Ma Weiming’s team is more than just this scientific research achievement. Electromagnetic guns and electromagnetic catapults are also made by the academician Ma Weiming’s team. They are truly national treasure-level scientists. Most of these equipment have come out of the laboratory, entered the stage of actual use, and achieved a leading position in the world. This has also changed the situation in which our country’s weapons and equipment development could only “chase” behind others. Presumably, the United States is also quite shocked in its heart.
