"There will be no problems with the power system. How do you think about the propulsion and transmission in the area behind this?" Liu Yijiu stood on the bridge and said to the huge space behind which was completely dismantled.

There were originally several layers in it, all of which were removed.

The Americans dismantled the eight heavy oil boilers inside, leaving only four steam boilers, allowing the Chinese side to slowly drive back the huge warship at a speed much slower than the cargo ship.

It was originally very empty, but now that the surrounding area is demolished, it looks even more empty.

Only two of the four huge drive shafts were installed flatly at the bottom of the cabin, and even the last propelling propellers were replaced with smaller ones that I didn’t know were removed from an old battleship.The original four-axle double rudder propulsion structure was only the outermost propulsion rudder due to the disassembly of the Americans.

They just allow China to use this to drive the warship back.

It is very good without letting the Chinese side tow it back with a tugboat.

"Originally, we considered using a hybrid of conventional power and nuclear power, but considering that the current conventional power technology is not enough, we simply use nuclear power. According to the technical parameters provided by the Ninth Institute, we will install the heavy oil boiler in the original location. Two small nuclear reactors...The propulsion system still uses a four-axis dual rudder mechanism. The reactor is placed in the area near the tail of the bridge. In this area, a turbine mechanism is installed in the middle, which can be driven by one or two. All the axles of the company are followed by two sets of steering wheels..."

Ai Guoxiu pointed to the empty area in the middle and introduced to Liu Yijiu.

Originally, the boiler of this kind of warship designed by the Americans was mainly placed under the bridge, which was also for the center of gravity consideration.

Now the location of the boiler has become two small nuclear reactors, and the weight has been reduced a lot.

"How to solve this impact on the center of gravity?" Liu Yijiu asked.

This situation is very obvious.

"Although there is a big difference between the number of nuclear reactors and huge heavy oil boilers, we need a stronger cooling system. At the same time, because the reactor is in the middle, we need to strengthen the protection. A thicker containment is adopted. At the same time, In order to supply electricity for the entire warship, we will install steam turbine generators in the intermediate power conversion area, so that the energy use of the entire warship can be supplied. In the cruising state, the operation of a reactor can ensure the demand for use. When high-speed maneuvering and more energy are needed, the two reactors can reach the battleship’s maximum speed of 38 knots when the power of up to 75% is turned on, which is more powerful than the original American heavy oil boilers and steam boilers. It runs almost 5 knots faster. Of course, if it reaches full power operation, it can even maintain a high speed of 42 knots an hour... A nuclear reactor running at 50% power can also reach 25 knots."

The power system will be very strong with the supply of two nuclear reactors.

The maximum speed of 42 knots can be regarded as a high-speed warship. Even many small frigates and destroyers cannot reach this speed.

Liu Yijiu naturally has no objection to this kind of performance, but the latter area will save a lot of space because of the entire power system change.In the interstitial area, dozens of Dongfeng-31 missiles will be installed, but other places are vacant.

Another question is whether the domestic imitation transmission main shaft and steering wheel can have sufficient strength.

The Iowa class uses two different propellers. The outer shaft propeller has a diameter of 5.563 meters with a 4-blade propeller; the inner side has a 5-blade propeller with a diameter of 5.182 meters.This design is mainly because the stern of the ship vibrates when the first Iowa-class ship is sailing at a high speed, so it is changed to this design.

In order to ensure that Iowa's performance can be improved, Liu Yijiu asked from the beginning to follow the original design.

The Americans thought they dismantled the main shaft, replaced the transmission shaft and the propulsion rudder. With China's backward industrial base, these can only be scrap iron.

Unexpectedly, Liu Yijiu was very familiar with such battleships.

The design of this slender hull is not because this design is the most reasonable, but when the Americans designed it to allow the largest battleship to pass through the Panama Canal locks, there was no way to reduce the width and pull The long hull is designed.Although the design is good for providing speed, it affects the airworthiness.

The shell is fixed and the Chinese cannot modify it at all.

If you want to make changes, it is considered to be rebuilt.

The two battleships Liu Yijiu worked so hard to get back from the United States were wasted.

One ship can be used for research, but two ships are completely unnecessary.Therefore, their goal was to turn this type of battleship, which was only slightly worse than the Japanese Yamato-class battleship during World War II, into a more terrifying sea monster, telling the U.S. emperor that it is not an aircraft carrier that can determine victory or defeat at sea.

It is Director Liu's goal to use the American foundation to transform, and then scare the American emperor and let them know what it is like to lift a rock and hit one's own foot.

Only in this way can people feel happy.

After all, the Republic used to keep up with the American imperialism.

Finally, there is an opportunity for the U.S. emperor to catch up with military equipment. How can we let it go?

A war cannot be fought, and the competition in preparation for war never stops.

If you forget the battle, you will be in danger, not just empty words.

"In terms of drive shafts, we can only imitate as much as possible. In terms of special steel, it is our shortcoming. Although the computer simulation proves that there is no problem, we have to wait for the final installation and sailing to make it clear..." No one can guarantee .

The country has only developed for so many years.

"The problem with the strength of the drive shaft is not big, mainly in the propeller of the tail. We have not manufactured such a large and high-precision propeller in China. Especially not the same specification and the same model." Ai Guoxiu also emphasized to Liu Yijiu. .

"There is no problem with the material composition analysis of this American drive shaft, right? The rest is the processing technology." The manufacture of heavy equipment, especially involving high precision, must be taken seriously.

Ai Guoxiu and Wu Tianhai nodded, and Wu Tianhai said, "This is indeed the case. The material has been analyzed, and the process problem is the key point. Jiangnan Shipyard has been conducting technical research in this area. However, manufacturing this When it comes to propellers, no higher progress can be achieved. The service life of each propeller is only two years..."

Two years!

It was manufactured by the American Emperor, but it can be used for more than ten or twenty years.

"It's just a process problem?" Liu Yijiu asked in disbelief.

If only two years have to be replaced, this is really a troublesome thing.Although it only takes a few days to replace the propeller.

The cost is really high.

"You need to ask the Jiangnan factory in detail about this. Two years, it's just a conservative data from there." Wu Tianhai said to Liu Yijiu.

Regardless of the specific project, they only need to coordinate the scheduling.

The shipbuilders with the most extensive domestic experience and the best technical reserves say that there is no alternative. What else can they do?

"That line, when it's over here, I'll go and take a look over there." Liu Yijiu nodded, there was a worry in his heart, fearing that Jiangnan Factory did so on purpose.

This is not a national project, and Jiangnan plant has not yet completed the 052 ship, orders and funds are not so sufficient.Millions of propellers are a lot of money.

"The space below this is too large to be fully utilized. If the weapon system can be installed inside, try to install it inside." Liu Yijiu looked at the warship shell problem, and then completed the modeling in his mind, inferring each Part of the occupied space, could not help but gave instructions.

Wu Tianhai naturally has nothing unacceptable to such a request, "We will use these spaces to give officers and soldiers more living space, and at the same time, store more ammunition. Only in this way can our warships be more survivable. "

While walking down the spiral staircase between each floor, they discussed.

At the bottom of the warship, the space is the smallest, but after removing some of the devices, it looks very large.The widest point is more than 20 meters, and the length is even more than 200 meters.The long and narrow space does not look very narrow.

"At the bottom of this position, the space is really small. This place was originally used to store shells, and we don’t need too many shells. For the main artillery shells with a diameter of more than 400 mm, there is no need for space. It’s vacant, and it’s not very useful to do anything else. You can install monitoring devices at the bottom. The integrated sonar system can be installed in various spaces at the bottom. The front and middle sections are transformed into torpedo cabins. The sonar system can be integrated and used more reasonably The space inside..."

It is estimated that no warship in the entire world will have so many sonar systems on the bottom.

According to Liu Yijiu's request, this submarine can become a submarine.

It's not the kind of model that I saw at the beginning, but there is a submarine at the bottom, except that it does not carry a submarine-launched missile.

If necessary, submarine-launched missiles can be installed in the water balance compartments on both sides.

"The horizontal ring array sonar is arranged in a circle along the bottom edge of the entire warship. The intercepted sonar detection part can be thrown out from both sides or the bottom. Passive ranging sonar, side array sonar, underwater collision avoidance sonar, etc., must be arranged. . I know that you didn’t consider this issue. Now you must consider it. With such equipment, anti-submarine helicopters cannot rely on the above anti-submarine helicopters. With such a large and sufficient space, even if our technology is not advanced enough, we must use it. Later, we will replace it!"

Liu Yijiu's words made everyone dumbfounded.
