Battle of the Third Reich Chapter 162: U Boat One Thousand and One (Medium)
""="('')"="()">
Passing the steel trestle bridge paved with wooden planks, Xu Jun and his group stepped onto the deck of U1001. Net..○Different from the flat and open upper deck of the previous submarine, the deck of this new submarine is slightly narrower in comparison. The steel deck engraved with anti-skid lines and drain holes extends along the central axis of the submarine to the command tower, then bypasses the command tower on both sides and then extends to a position about ten meters before the bow. This long and narrow deck is only 1.5 meters wide at its widest point, and its narrowest position is on both sides of the control tower. It is only fifty centimeters wide, just enough for a sailor to pass.
The hull outside the deck presents a clear arc line, from both sides of the deck down to the water surface. The cross-section of this ship is circular, which is just the first impression this submarine leaves on visitors.
In the past, the German submarine had a very complicated cross-sectional structure. It only added a bunch of necessary cabins outside the pressure hull. The overall shape of the fuel tank, ballast tank, head and tail balance cabin, etc., still cannot be separated from the water surface. The influence of the ship is generally a battleship that can dive, and the surface of the ship is the home field of this ship. The underwater line type is only a secondary issue in the designer's mind. The overall design of the German submarine pays more attention to the maneuverability and seaworthiness during surface navigation. The surface speed and endurance are the hard indicators of a submarine at that time.
Although the xx-type submarine adopts a concept that transcends the times, the designer’s idea still fails to circumvent the original thinking mode. Although this submarine adopts a cross-age double-hull design, it also uses a large number of lines. Based on the results of fluid dynamics at the time, many details have been clearly optimized. However, due to the inertia of the thinking mode, the submarine was finally breathless in the finalized design. The designer installed the submarine. An unnecessary wave breaking bow, while also adopting a corresponding design in the hull structure.
Although this submarine has transcended the era in concept, the design of the boat exposed the limitations of the designer's vision at that time, making it a legendary super electric boat. In the end, it can only become a nondescript transitional model, which is far below the actual value of the kind of concept she represents.
In Xu Jun's view, this sharp, blade-like bow is completely superfluous, but it weakens the original potential of this submarine. Since this submarine adopts a double-layer hull design as a whole, this means that any change in the shape of the non-pressure hull outside the inner pressure cabin will not affect the internal layout. Xu Jun did not hesitate to chop off the front ten-meter-long blade-shaped wavebreaking boat bow structure. That steel part will only affect the submarine's underwater maneuverability. Just imagine when a chopstick and a spoon are stirred in the water It can be found that this slightly forward-leaning wave breaking bow will cause much resistance to the submarine’s underwater steering maneuver.
Xu Jun replaced a blunt shell at the original bow of the boat, because the internal structure is difficult to further optimize, because of the foundation of this submarine, it cannot be modified into the popular drop line shape in later generations because of the aspect ratio. For the sake of. Xu Jun could only take a step back and replaced this submarine with a whale-shaped bow that was popular in later generations, and was as close as possible to the advanced conventional submarines in the future.
In order to replace the bow of this boat, Xu Jun exhausted his efforts. There is no similar information in his database. He can come up with the design drawings of mainstream diesel-electric submarines in the 1950s, but the performance of those submarines is not comparable. How much improvement **** has, some designs are not even as good as this submarine of the Nazi era.
Xu Jun could only draw a basic sketch based on his original personal memory for the design bureau to make improvements. A bunch of fluid dynamicists and mathematicians spent a week. Finally, they figured out the optimal solution they thought was the best. At the same time, the heads of state's brains opened their eyes to these scholars, opening a closed window for them and seeing another new path of development. In fact, these problems have been revealed in the design of torpedoes in the past, but no one has specifically conducted further research for this purpose. This time, Xu Jun's design has completely lifted the veil. Experts have begun to gear up, looking forward to making more significant discoveries in this field.
The new bow is proven to greatly improve the underwater performance of the submarine, and the design of the head of state has surpassed the entire era. No one has proposed a similar concept before, a new type of submarine focused on underwater combat, Deniz finished reading the design drawings. I can't wait to immediately go to the command department and worship the apostle.
Since Xu Jun has made improvements to the xx-type bow, the structure of the stern must of course be changed accordingly. However, Xu Jun found that the stern design of the xx-type boat has reached the level of the 1950s, which can be said to be the pinnacle of the current technology. In addition to the line type and the overall consistency, the structural arrangement has been separated from the usual surface of the German submarine. Ship mode.
If comprehensive changes are made like those submarines of later generations, it will definitely affect the structure of the entire tail section, and in the absence of more powerful engines, dual-engine dual-axis propulsion is still the world's routine for a long time. The mainstream design of diesel-electric submarines.
Of course, Xu Jun knows the single-shaft large-tilt propeller, and also knows the cross and the x-shaped balance rudder. The problem is that these technologies are beyond the scope of his database. He can only make some experimental improvements based on the combination of the technology and memory he has in his hands. Xu Jun optimized the outline of the stern as much as possible, reinforced the horizontal and vertical rudder mechanisms on the original basis, and enlarged the area of the rudder surface. He was also on the horizontal guide wing with fixed propeller shaft. Two air deflectors similar to airplane **** are installed, which can increase the effectiveness of the horizontal rudder in high-speed navigation. At the same time, through the opening and closing of the air deflectors on both sides, it can also be used as an emergency rudder to adjust the heading and hull balance of the submarine .
Under Xu Jun's modification, this submarine has truly become a transitional version, a transition of an era. According to Xu Jun's estimation, it may reach the level between the 1960s and 1970s. Of course, it is only his personal opinion. In fact, there should still be a big gap with those three-generation mainstream submarines. However, in this era, this submarine will be a nightmare for all enemies. Xu Jun firmly believes that with the performance of this submarine, no **** ship can match it. If it is controlled by a cunning captain, the enemy will even At the moment of sinking, he would never know who attacked him.
Xu Jun corrected the cross-sectional shape of the submarine to make it closer to a circle. Of course, it is impractical to achieve a perfect circle. This ship should be considered to be closer to an ellipse, and looks more plump than the original egg shape. Therefore, the underwater mobility has been greatly improved.
"Go this way, please. My head of state." Captain Heinke stood by the control tower and waited, temporarily adding a wire rope fence for safety.
Xu Jun’s changes to the command tower are not too great. He really likes the original shape of the xx-type command tower, so he basically retains the original basic design, with only minor modifications in some details. The original command tower The floating design of the top of the upper layer was changed to vertical downwards. In Xu Jun's view, the upper layer was originally wrapped under the top of the command tower. This kind of floating was unnecessary.
The two front and rear dual electric 20mm machine turrets have been retained. Although Xu Jun doesn't think this thing can play a big role, it is better than nothing. It should be no problem to scare low-altitude targets. It can also have a good sound and light effect when used to shoot some surface targets. More importantly, it can slightly increase the safety of some crew members, so that they will not feel that they are empty-handed, so Xu Jun finally decided These two anti-aircraft turrets, which have almost become the characteristics of xx, are retained, and newer replacement products are also considered in the future to increase the anti-air firepower of this submarine.
The u1001 has only three external hatches on the whole boat. Unlike previous models, this submarine has one tail torpedo loading hatch less than ordinary conventional submarines. Because this submarine does not have tail torpedo launch equipment. Of course, there is no cumbersome tail torpedo bay.
All the weapons of the submarine are installed in the bow of the submarine. Generally, only small offshore submarines can do this. This configuration is a bit special for a giant shark of more than two thousand tons like the u1001. In fact, this is also a valuable experience gained by the German Navy using submarines for a long time. Although the tail torpedo increases the means of submarine attack, it also consumes valuable tonnage. Most of the time, the submarine faces the enemy head-on, and there are not many opportunities to actually use the tail torpedo. Turning the bow to attack is both troublesome and dangerous. Many submarine captains avoid the use of tail torpedoes, but treat it as a last resort.
The **** model uses technology beyond the times. The new hydraulic auxiliary loading equipment gives her the ability to quickly reload torpedoes in battle. This improvement is coordinated with the submarine’s excellent mobility and concealment. XX will always have the initiative on the battlefield, instead of the usual After shooting out the torpedo, the wolf chased by the enemy ship rushed. Therefore, canceling the tail torpedo tube will not reduce her combat capability, and the saved tonnage and space can be used to install more advanced equipment.
Except for the torpedo loading port in the bow, the **** submarine has only two personnel access hatches, one of which is on the top of the control tower platform, directly connecting the captain's control tower and the command cabin. The other hatch is inside the control tower enclosure. A side door on the control tower shell enters the control tower, and then the submarine can be accessed through the access hatch on the deck.
If you want to use the hatch in front~IndoMTL.com~Xu Jun must step on the pedals on the shell of the control tower, climb the four-meter-high control tower, and climb into the fence to reach the observation deck where the hatch is located. Although Xu Jun didn't mind doing this, no one else in the room would allow him to take such a risk.
So a group of people can only enter the submarine through the second hatch. Not only Germany, submarines of all countries will leave a hatch in this location. Xu Jun insisted on asking himself to be the first to enter the submarine, and everyone had to obey obediently on this issue. The head of state put his stick under his arm, and slowly climbed down the straight iron ladder.
When Liang Liang’s riding boots stepped on the floor covered with a rubber non-slip mat, Xu Jun turned his head and looked around. As soon as he raised his eyes, he saw a chef holding a soup spoon standing in front of the electric stove dumbfounded.
"Hi, Reinhardt!" The chef stood trembling and saluted. The spoon in his hand slammed into the smoked pig's feet hanging on the bottom of the closet. The two kilograms of salted and shook there. Back and forth.
"Hi... Forget it, you continue to work." Xu Jun raised his scepter and knocked the brim of his hat, then turned his head and looked towards the top of the ladder.
