Chapter 743： Submarine continued

The luxury private submarine test, just follow a supply boat and speedboat with test equipment, ready to rescue. But the other submarine is different. It is underwater from the dock, and above the water is a destroyer and a supply ship.

Entering the water from the water is a process of enjoyment for those who like to dive. Especially the surrounding sound is suddenly enclosed in a small space, especially so. Guo Tailai is very enjoyable.

Entering the submarine with the boss is the six designers who participated in the submarine design, basically belonging to each of the five permanent teams and one Ukrainian expert. It is really powerful to be able to follow the sea test. Everyone wants to see the luxury private submarine.

The sea water selected in this sea area is very clear. It is a good place to test, and it is not deep. The deepest place is only over 50 meters. It belongs to the area where Guo Tailai does not need to wear a pair of crotch to get in and out of the water. It’s not that the submarine was crushed into a group of discus on the spot. There was no other security risk when Guo Tailai had a problem. Moreover, all the parts Guo Tailai have checked, and there is no such dangerous situation.

The submarine dive quietly, Guo Tailai and another designer sat in the viewing cabin, watching the outside scene slowly sinking, all kinds of fish swimming through the transparent porthole in front, the sound around it was quiet and messy.

Although they are all submarine design experts, to be honest, there are not many opportunities to see this underwater world underwater. The submarines they designed previously can all be combat submarines in various countries. There are very few such viewing cabins, not to mention the large portholes next to each seat. This situation has never been seen before, sitting in the first class of the airplane and looking outside. Several design experts are also quite emotional.

After a while, the submarine hovered silently at a depth of forty meters. The two crew members responsible for driving the submarine stared nervously at a pile of instruments. So far, nothing has been found about the control system.

The next step is for the experts. Although every system has been closed and tested on land, it is still necessary to retest it here. Air monitoring system, underwater structure pressure measurement, control system front and rear left and right travel, internal and external lighting systems, and so on.

If it is a real combat submarine, there are too many tests to be tested, underwater noise, weapon systems, communication systems, radar systems, sonar systems, scanning systems, etc., but here, almost none of them. Of course, the basic communication and scanning must be tested, otherwise the underwater is prone to problems, and the civilian submarine is focused on safety, stability and comfort.

For example, underwater toilets are an aspect that requires rigorous testing. A normal submarine, certainly not a luxurious toilet, even a small space, and must follow certain operating procedures to complete. But in the private submarine, this is a very important system, not only the bathroom is very large and comfortable, but also uses it on the land, no difference, one-click use. Subsequent work is handed over to the electronic system for control.

When Guo Tailai was very happy to test it on his first private submarine, another small submarine was also being tested. However, the test has already started from the dock. A small shaftless pumping system that matches this small submarine, easily speeds up the small submarine to a speed of twenty-five knots.

The destroyer on the water has been on the monitor, but even if the speed of the small submarine has reached 25 knots, the monitors can hardly hear the noise of any submarine propulsion system. If it is driven by a power shaft propeller, how quiet it will be, there will be some slight characteristic noise, but this small submarine is really almost no sound. In their monitor headset, even if the amplification volume is heard, it is only noisy. The noise of the ocean background. If it is not clear that the submarine is below them, the monitors simply think that the submarine does not exist.

There are a bunch of instruments on the destroyer on the sea in the monitoring test, and among the underwater submarines, several technicians are also testing. This system is really too quiet, and you can't hear the sound outside. They are inside the submarine, and they can't hear too much noise. Quiet is just a cheer.

At present, this set of shaftless pump spray cancels the mechanical transmission in the traditional sense, and the generator generates power to directly drive the shaftless pump pusher, that is, noise reduction and space saving. It is one of the best noise reduction technologies at present, at least about 10% noise reduction, and can improve the propulsion efficiency and achieve higher speed. The power output mode is directly simplified, and the mechanical structure has undergone a fundamental change. The reaction force of the water jet pumping water flow directly advances, and the anti-cavitation ability, low noise, high efficiency, and low resistance are almost all advantages.

If our nuclear submarines are able to use such propulsion technology, several technicians can even conclude that they can definitely achieve a sea noise level of 90 decibels. If the depth of the submarine is enough, our nuclear submarine can be said to be stealth.

What's more, the engine efficiency of this shaftless pumping system is close to 80%, which can save energy and improve the range. Because there is no drive shaft, the sealing is excellent, and all of them are advantages.

Although Guo Tailai only casually took out a small shaftless pumping system, the Navy has paid extraordinary attention. This time, the team was tested by Liu Shaoer from the Beijing Naval Academy and an acquaintance of the fat man.

With a test report on the road that was freshly baked, General Liu was almost unable to hold his heart. Needless to say, the light power efficiency, small footprint and effective noise reduction are enough to make General Liu crazy. As long as the submarine has been in the Navy, who does not know what these advantages mean? Coupled with the sound-absorbing tiles and sound-insulating materials developed by the fat company before, they are all equipped, I am afraid that our submarine **** fish can be freely transferred to the place we want to stroll and will not be discovered.

What is the blockade of the second island chain of the first island chain? When it is really necessary, we don’t have to make a big move. As long as one of our submarines floats in some key places, it uncovers the back. Can you scare many people into the urine?

"All the tests are normal!" Guo Tailai's test is also nearing completion. Looking at the perfect test results, Guo Tailai laughed loudly and announced: "Upward, we change a deeper place and continue to test the depth."
