Chapter 1487 The Submarine Continued
Luxury private submarine testing, just follow a supply ship and high-speed yacht with test equipment, ready to rescue at any time. But the other submarine is different. When it comes out of the dock, it is underwater, and above the water is a destroyer and a supply ship.
Going from above water to underwater is an enjoyable process for those who like diving. This is especially true when the surrounding sounds are suddenly enclosed in a small space. Guo Tailai enjoyed it very much.
Those who entered the submarine with the boss were six designers who participated in the design of the submarine, basically belonging to the Wuchang team, one from each country and one Ukrainian expert. Those who can follow to conduct sea tests are those who have really contributed. Everyone hopes to see the best kind of luxury private submarine.
The water in the selected sea area is very clear, which is a good place for testing. It is not too deep. The deepest place is only more than 50 meters. It belongs to the area where Guo Tailai can freely go up and down in the water without wearing any equipment. It wasn't that the submarine was crushed into a ball of discus on the spot, and Guo Tailai would not have a safety risk if something went wrong. What's more, Guo Tailai has inspected all the parts, and there will be no such dangerous situation at all.
The submarine dived silently. Guo Tailai and another designer sat in the observation cabin, watching the scene outside slowly sinking. Various fishes swam through the transparent porthole in front of them, but the surrounding sounds were completely silent.
Although they are all experts in submarine design, to be honest, there are not many opportunities to really see the underwater world underwater. The submarines they designed before were all combat submarines from various countries, and it was rare to have such a large viewing cabin, not to mention that there were large portholes next to each seat to see the outside. Such a situation like sitting in the first class of an airplane and looking out has never been seen before. Several design experts are also quite emotional.
After a while, the submarine hovered quietly at a depth of 40 meters underwater. The two crew members in charge of driving the submarine stared nervously at a bunch of instruments. So far, they haven't found anything wrong with the control system.
The next thing is for the experts. Although each system has been tested on land, it still needs to be tested again here. Air monitoring system, pressure measurement of underwater structure, front, rear, left, right, up and down travel of the control system, internal and external lighting systems, etc.
If it is a real combat submarine, there are too many things to test, such as underwater noise, weapon system, communication system, radar system, sonar system, scanning system, etc., but here, almost none of these are used. Of course, basic communication and scanning must be tested, otherwise problems will easily occur underwater. For civilian submarines, the focus is on safety, stability and comfort.
For example, going to the toilet underwater is an aspect that requires rigorous testing. A normal submarine certainly does not have such a luxurious toilet, and even the space is pitifully small, and certain operating procedures must be followed to complete it. But in private submarines, this is a very important system. Not only is the bathroom large and comfortable, but it is also used in the same way as on land, with one-button operation. Subsequent work is all handed over to the electronic system to control.
While Guo Tailai was happily testing his first private submarine, another small submarine was also being tested. However, testing has already begun as soon as it leaves the dock. The small shaftless pump system matching this small displacement submarine easily increased the speed of the small submarine to a speed of 25 knots.
The destroyer on the surface has been listening, but even though they know that the speed of the small submarine has reached 25 knots, the listening personnel can hardly hear any noise from the submarine's propulsion system. If it is driven by the propeller of the power shaft, no matter how quiet it is, there will be some slight characteristic noises, but this small submarine really has almost no sound. In their monitoring headsets, even if the volume is turned up, all they can hear is noise ocean background noise. If it is not clear that the submarine is below them, the monitoring personnel simply think that the submarine does not exist.
A bunch of instruments on the destroyer are monitoring and testing on the sea surface, and several technicians are also conducting tests on the underwater submarine. This system is really too quiet. It doesn't matter if you can't hear the sound outside. They are inside the submarine, and they can't hear too much noise. It's so quiet that people want to cheer.
At present, this set of shaftless pump jets cancels the mechanical transmission in the traditional sense, and the shaftless pump thruster is directly driven by the generator to generate electricity, which not only reduces noise but also saves space. It is one of the best noise reduction technologies at present, which can reduce noise by at least about 10%, and can improve propulsion efficiency and achieve higher speeds. The power output mode is directly simplified, and its mechanical structure has undergone fundamental changes. It directly uses the reaction force of the water sprayed by the water jet propulsion pump to move forward. It has strong anti-cavitation ability, low noise, high efficiency, and small resistance. Almost all of them are advantages.
If our nuclear submarine can use such propulsion technology, several technicians can even conclude that it can definitely reach the ocean noise level of 90 decibels. If the diving depth of the submarine is sufficient, our nuclear submarine can be said to be completely invisible.
What's more, the engine efficiency of this shaftless pump propulsion system is close to 80%, which can greatly save energy and improve the voyage. Because there is no drive shaft, the sealing is excellent, and all the performances are advantages.
Although Guo Tailai just took out a small shaftless pump push system very casually, the navy paid special attention to it. This time the test team was led by Rear Admiral Liu of the Beijing Navy Yard, who was also an acquaintance of Fatty.
Holding the freshly released test report along the way, General Liu couldn't hold back his beating heart. Needless to say, the features of high power efficiency, small footprint and effective noise reduction are enough to drive General Liu crazy. As long as anyone in the navy has been on a submarine, who doesn't know what these advantages mean? In addition, if the sound-absorbing tiles and sound-proof materials developed by Fatty Company are fully equipped, I am afraid that our submarine, the big black fish, can wander around wherever we want without being discovered.
What is the blockade of the first island chain and the second island chain, when it is really necessary, there is no need to make any big fanfare, as long as one of our submarines floats up and reveals its back in some key places , can scare many people into the urine, okay?
"All the tests are normal!" Guo Tailai's test is also nearly completed. Seeing the perfect test result, Guo Tailai announced loudly with a smile: "Go up, let's go to a deeper place and continue to test the diving depth."
