The research on underwater gliders in China started late. At present, there are five scientific research units studying it, namely Shenyang Institute of Automation, China Academy of Sciences, Institute of Robotics and Automotive Technology, Institute of Oceanography of Shanghai Jiaotong University, Zhejiang University and China Ocean University.

2065438+On May 22nd, 2004, the water glider independently developed by Tianjin University passed the test in the northern part of the South China Sea1500m, which set a number of records for the China water glider, such as the longest trouble-free voyage, the longest time, the most profile movement and the deepest working depth, and broke through the foreign technical blockade. The water glider independently developed by Tianjin University is called Haiyan, which uses the latest hybrid propulsion technology and can work continuously for about 30 days. Compared with the traditional unmanned cableless submersible (AUV), Haiyan is lighter and thinner. It looks like a torpedo, with a length of 1.8m, a diameter of 0.3m and a weight of about 70kg. It combines buoyancy drive and propeller propulsion technology, which can not only achieve the same turning and horizontal motion as AUV, but also have the ability of traditional glider profile gliding (that is, zigzag motion).

10On June 55438+05, the underwater glider developed by Shenyang Institute of Automation, Chinese Academy of Sciences ended its one-month sea trial in the South China Sea, and completed the synchronous area coverage observation test and long-distance observation test of several gliders. In the long-endurance test, the total voyage of the glider at sea exceeded 1000 km, reaching 1022.5 km and lasting for 30 days, setting a new record for the longest voyage and the longest working time of the deep-sea glider in China.

In the future, China's military enterprises may produce a large number of enlarged petrels. This underwater robot can carry large sensors and detect frogmen, mines and submarines at a longer distance, and China's anti-submarine capability in the South China Sea is expected to jump. In addition, they may even carry weapons to carry out underwater escort or attack missions.

At the beginning of 20 15, China accused Viet Nam of sending "frogmen" to the waters where China confronted China. They laid a large number of obstacles such as fishing nets and floating objects to interfere with Vietnamese ships. The appearance of the armed version of Haiyan in the future will completely invalidate the jamming tactics of Vietnamese frogmen-China underwater combat robots will patrol around the drilling platform like sharks, and will automatically attack once they detect the approach of Vietnamese frogmen.
