The submarine was carrying out a routine cruise mission of the Parrot Navy this time. Its main purpose was to monitor the every move of the Longxia Navy at the doorstep of Longxia.
It is also because Longxia lags behind the West in the development of submarine research and development and anti-submarine technology, which has given other countries an opportunity to take advantage of it, allowing them to swagger into our territorial waters with their submarines and monitor the movements of our warships. At the same time, it has also created a lot of trouble for our country to safeguard the "Nine-Dash Line".
Xu Jianguo and his group were naturally unaware of this matter and remained on the Qiongzhou ship, heading towards the target sea area.
…
Although life on the ship was boring, fortunately Xu Jianguo was a quiet person who didn't like to move. He read books and drank tea, ate and slept on time. When he had nothing to do, he would go for a walk and look around on the deck, so he didn't feel so bored.
A day later, the Qiongzhou and two other frigates finally arrived at the target sea area of this mission.
This sea area is located in the southern territorial waters of Longxia Kingdom. The water is clean and transparent, blue and deep. The sea surface shimmers under the sunlight, like a huge piece of blue silk inlaid with countless dazzling gems.
This is where they are about to start testing the unmanned submarine. Everyone is full of anticipation at this moment, but also a little nervous.
The unmanned submarine tested this time can be said to be the result of Xu Jianguo's efforts throughout the past year, and it can also be said to be the result of the hard work of countless engineers from the Longxia Weapons Research Institute. It contains a summary of knowledge from multiple fields, such as fluid mechanics, chemistry, physics, materials science, radio science and acoustics.
As the anchors of the three warships sank into the sea, Xu Jianguo also appeared in the conference room with Zhao Huanbin and other engineers from the institute.
At this time, Wang Fengshan was standing at the front. As a representative of the navy, he needed to first motivate and mobilize everyone, and then Xu Jianguo, the director of the institute, would assign specific tasks.
"Comrades, everyone who can attend this meeting today should know why it is for. I won't say anything extra, I believe you all understand that the unmanned submarine that Engineer Xu and his team have painstakingly developed is crucial to the future development of our country's navy. Although we can't get involved in the testing, I require each of you to understand the importance of this test mission. During the test, everyone must unconditionally execute Engineer Xu's orders. Anyone who disobeys will be dealt with by military law!" Wang Fengshan said with a serious expression.
As soon as the words fell, the captain of the Qiongzhou, Zhu Dejun, the deputy captains Feng Dagang and Shi Xiangyang, as well as the chief officers and training staff of the other two frigates, immediately stood at attention and loudly agreed, "Yes!"
After Wang Fengshan finished speaking, Xu Jianguo walked to his seat and began to assign tasks to everyone.
The assignments for the institute's test engineers had already been arranged before they arrived in Qiongzhou.
So what we are mainly talking about here is the work distribution of the three naval ships.
Because the operating radius of the unmanned submarine can reach an astonishing thirty nautical miles, in order to prevent any accidents, he needs three warships to ensure that there are no other ships interfering in the surrounding test area.
What we need to be especially wary of are the fishermen's fishing boats, because in later generations, Chinese fishermen have used fishing nets to salvage foreign unmanned submarines more than once.
After arranging all the tasks, Xu Jianguo led a group of engineers from the research institute to the deck. At this time, the unmanned submarine had already been hoisted out of the cabin.
Under Xu Jianguo's order, Deputy Director Zhao Huanbin began to arrange for engineers to come forward to lift the canvas and start the final inspection before the test.
This unmanned underwater vehicle, named "Dolphin" by Xu Jianguo, looks like a nimble deep-sea elf. Its main body is streamlined and its shell is made of high-strength titanium alloy. This material can not only withstand the huge water pressure in the deep sea, but also has good corrosion resistance.
It is about two meters long and about seventy centimeters to one meter in diameter. Its small size contains huge energy.
The Dolphin unmanned underwater vehicle is equipped with an advanced power system and uses a new battery technology developed by the institute's special research team. A single charge can support it to sail continuously underwater for up to a week.
This battery has the advantages of high energy density, fast charging and good low-temperature performance, enabling unmanned submersibles to adapt to various complex marine environments.
In terms of propulsion, it combines propeller propulsion and seawater jet propulsion.
The propeller is specially designed to provide stable power and reduce noise when sailing at low speed.
Seawater jet propulsion comes into play when sailing at high speeds, enabling it to reach the target area quickly.
The detection system of the "Dolphin" is also unique. A high-resolution sonar device is installed on its front end. This sonar has an extremely wide detection range and can accurately scan the seabed terrain, obstacles and other potential targets within a radius of several kilometers.
Whether it is reefs and shipwrecks on the seabed, or unidentified objects hidden in the mud and sand, they cannot escape its keen "hearing".
At the same time, it is also equipped with a multispectral optical sensor that can observe the ocean environment in different spectral bands.
In the visible light band, the activities of marine life, the turbidity of seawater and other information can be clearly captured.
In the infrared band, areas with abnormal temperatures can be detected, such as submarine volcanic activity or other heat sources.
