Chapter 248 How can the line shape change?
Members of the Joint Fleet delegation did not know what Xu Xingchen was doing.
It was supposed to be on Yamato's ship, but everyone on his side followed him and waited to get on the ship with him, but he ran to Musashi's side first.
He ran on Musashi's side again, and he ran back to Yamato.
The group of ship girls were in a mess. When they were considering whether to run with Xu Xingchen again, Musashi stood up and shouted loudly and stopped the other companions:
"The General Flagship and the Marshal have something to talk about separately. Everyone should come on my boat and don't go over and disturb me..."
With Musashi's explanation, most ship ladies didn't think much about it and went on Musashi's ship one after another.
However, there are ship girls who are familiar with Musashi, such as Shinno's eldest sister, who came to Musashi after getting on the ship:
"What are you talking about? Didn't you talk about in the room before? Are you going out for a trial voyage now?"
"I'll explain to you when I go back..."
Musashi replied casually, pulling Shinno behind him. After everyone else boarded the boat, he put away the gangway to control the hull to set sail, and at the same time he greeted his companions:
"Please note that I am setting sail and leaving the port now, and it will take some time to start weapon testing. Everyone in the joint fleet can move at will.
"Of course, friends from the Marshal's Mansion can also visit at will, but in order to prevent getting lost in the cabin, it is best for everyone to follow me together."
Musashi was originally an extroverted and casual personality, but now most of his thoughts are on the effect of hull modification.
After a very simple arrangement of his companions, he began to greet the ship ladies from the marshal's mansions in Hangzhou and other places to visit.
This situation seems to be Musashi being a tour guide, but in fact, they are all places where Musashi is curious about it, that is, those places where the transformation and adjustment are first of all, weapons and equipment.
When Musashi saw the new weapon on his hull, he had to ask the introduction of the Marshal's Mansion's ship girl. He didn't know which side was the tour guide for a while.
Although Musashi's ship girls were asked to move freely, what they were curious about was also the transformation effect of Musashi's body.
If it is new equipment, they may not understand it by themselves, so they have to ask the ship girl from the Marshal's Mansion to introduce it.
So in the end, except for a few ship girls who had sex and got separated, most of the ship girls still got together and first went around the deck to visit the adjustments on the outer periphery of the ship.
Everyone came from behind the bridge, and now they all saw the newly added fourth main gun at a glance.
Someone who was very familiar with the Yamato-class hull could not help but ask Musashi subconsciously:
"Senior Musashi, after adding the fourth main gun, how much has your hull displacement increased? How much has the power decreased in the unit?"
Musashi sensed the state of his hull and replied thoughtfully:
"The displacement...it seems to have basically not changed...because the weight of the unit has been reduced by more than half, and other miscellaneous adjustments are just enough for the weight of a main gun. As for the power of the unit, it seems that it has not increased to 200,000 horsepower..."
An exclaim immediately sounded at the scene, which directly overturned everyone's previous speculation. Everyone thought that the power of the crew would definitely be reduced if the main gun was added.
"How is this possible!"
"The power of the main gun has not decreased but increased instead?"
"According to the displacement of the Yamato class, the speed of 15 horsepower is 27 knots, and the speed of 20 horsepower is 29 knots..."
When we heard someone talking about speed, we subconsciously looked around, looking at the waves under the side of the ship and behind the waves.
Musashi's eyes were wide open:
"My feeling...it seems...it seems...it seems that more than 29 knots, I should be able to run to more than 30 knots, at least 30 knots, and the unit is speeding up too fast..."
Shinno next to Musashi immediately retorted:
"Impossible. The linear shape and displacement of your hull are fixed, and the corresponding speed at a fixed power is also fixed. The trial displacement of 69,000 at 20 horsepower is at most a maximum speed of 29.5 knots. Overloading to 215,000 horsepower can only reach 30 knots."
Musashi immediately shook his head and said:
"No, my hull's linear shape... has changed. The nose of the ball seems to have become bigger, the stern seems to have been changed to square, and even... the entire hull has been reshaped..."
When this sentence was said, it was not just Musashi himself, but the girl of the United Fleet around him, who was shocked again.
Everyone has seen the transformation, and even the transformation of battleships into aircraft carriers, has been heard of.
However, the transformation has changed the line shape of the hull, which is unheard of.
Shinno opened his eyes wide and asked:
"How could the linear shape change? Musashi, aren't you kidding? And even if it's a square stern, it can't increase the speed by half..."
Musashi nodded solemnly and said:
"Of course it's true. I can feel it. You can see it even if you go to the tail of the ship..."
Musashi was also a little concerned, so he took the ship girls all the way, crossed the two turrets behind the hull, and came to the tail of his hull.
Everyone discovered that Musashi's originally round stern had now become flat, as if it had been cut with a knife.
The ship girls know that the existence of the square stern, and this kind of shooting can increase the maximum speed at the same power.
The warships of World War II era have already adopted the square stern design face. The most famous one is the Forbidden Battleship built after the war, and is the only square stern battleship built.
However, the square stern of the avant-garde era, like the early ball noses of the warships at that time, was still in an early exploration state. It was to rely on pool experiments to obtain approximate experimental results without computer simulations, and then apply them to a relatively conservative and small scale.
The vanguard's hull is like a spindle with pointed ends. One end of the tail is cut off, and the cut part is very small, and at first glance it still looks like a spindle.
The "square" size of the stern of Musashi's ship is much larger than that of avant-garde. Like modern destroyers, the entire stern is flat, and the stern is as wide as the middle of the hull.
Of course, Musashi's stern was not cut off, and her hull had not changed in length, but the sides of the ship were expanded outward and extended, leveling with the top of the stern.
Because the longer the waterline, the smaller the resistance to rising waves, and the actual effect of a square ship stern is to increase a virtual ship stern length.
So if you simply cut off a piece of the original hull and turn the stern into flatness, the speed will not only not increase compared to the original, but may instead decrease.
According to early designers' research, it was believed that avant-garde simple square ship stern could increase the speed of about one-third of the knot at the same maximum power state.
Musashi's current large-scale square ship stern, coupled with a large mature ball nose, can increase the speed by at least one additional cent at the same power.
Musashi took Shinno and other ship girls from the Marshal's Mansions, together with Shinno and other ship girls from Wuhan and Harbin, looking at the rolling waves at the stern of the Musashi ship, and feeling the speed of Musashi's hull's sailing speed continues to increase.
After more than ten minutes, the Musashi's speed finally increased to 30.5 knots, just one knot higher than the expected maximum of 29.5 knots.
In this way, the speed of the full load state can still reach 30 knots steadily.
However, compared to the maximum speed of this section, what everyone cares more about is that Xu Xingchen can adjust the hull line itself.
