![]() The Chairman of Tuy An District People's Committee said that on the body of the "object" described there are two ways of fanning like a propeller in this tail with Chinese characters. ![]() On December 19, this torpedo was received by the Phu Yen Border Guard and then handed over to Khanh Hoa Province's Region 4 Command for "handling", according to Chairman of Tuy An District People's Committee Bui Van Than. ![]() According to domestic newspapers, the torpedo with a length of 6.8m with a diameter of 54cm was brought by a 40-year-old fisherman into the area of ?Mai Nha isle, more than 1.2 nautical miles from Phuoc Dong coast in Tuy An. It is confirmed that this is a torpedo produced in China.Ī fisherman named Tran Minh Thanh in Tuy An district discovered a "strange object" - which was later identified as a torpedo - while fishing near the shore. After the fishermen found the object, they were dragged home and reported to the authorities. On 18 December 2019, a fisherman in the country found a torpedo-like unidentified object found on the coast of Fuyan province in central Vietnam. After successful development, the tactical indicators are directly chasing its latest mod7 type. The original reference object of the fish-10 is the improved MK48 heavy torpedo mod6 in the United States. The three-component fuel consisting of Otto 2 fuel + HAP + water is the fuel with the highest energy density in torpedoes so far, and it also gives the fish-10 the world's advanced range and speed. The three "components", the gas plus the water vapor together become the working fluid of the latter turbine. In order to effectively cool the combustion chamber while fully utilizing the excess heat energy, the fish-10 engineers installed a container in the filling system to spray cooling water into the combustion chamber internally, thus forming a water vapor. At this time, if the seawater is introduced for cooling, the thermal efficiency is lowered. However, the problem that arises is that the heat energy generated by the combustion is too high, and the material of the combustion chamber cannot be absorbed due to overheating. The advanced torpedoes at home and abroad usually adopt the method of adding hydroxyl-ammonium perchlorate (HAP) to form a high-energy dual-component fuel. %) and a mixture of dibutyl succinate (23.5%). The so-called Otto fuel II is 1,2 propylene glycol dinitrate (76%), o-nitrodiphenylamine (0.5). On torpedoes, there is an important single-component fuel called Otto fuel II. Wake detection generally requires that the torpedo capture and enter the wake at a distance of about one kilometer from the ship, and finally attack the ship according to the direction generated by the wake. And electromagnetic anomalies caused by the different motion states of the wake water molecules and other water molecules. The essence is the scattering of sound and light by the bubbles in the wake. Wake detection is a kind of guiding method developed by the torpedo using the physical characteristics of sound, light, electricity and magnetism generated by the ship's wake, which is different from the general seawater. The advanced torpedo represented by fish-10 has begun to adopt the integrated wake detection method. The former is gradually being eliminated due to the small distance. Generally speaking, the end guidance method of torpedo is divided into sonar detection technology and wake detection technology. One of the important reasons why the Fish-10 has received attention is the use of high-speed fiber guidance for remote control.Īfter sailing to the approximate area of the target, the torpedo will open the end guidance mode to find the specific location of the target. China's new generation of submarine-launched heavy torpedoes, the Fish-10, has made strides in the performance of composite guidance and propulsion modules in the torpedo head, which has made its comprehensive performance comparable to that of the world's most advanced torpedoes. China Fish-10 has a speed of 50 knots and has a power range of no less than 50 kilometers, which is a heat-driven torpedo.
