In nature, there is a theorem that the greater the resistance an object encounters, the more difficult it is to obtain a faster speed.
For example, in the ocean, the speed of a submarine is difficult to match that of a ship. Because the resistance of sea water is very high, it is not easy to sail at high speed in sea water.
In the same way, although a ship sailing on the sea will experience slightly less seawater resistance, it is definitely not as small as air resistance. The speed of a ship on the sea needs to be faster than the speed of an aircraft, even if it is a miniaturized remote-controlled unmanned helicopter
, is not an easy thing either.
"Brother Shitou, you have fallen into a misunderstanding of your thinking!" Li Cai reminded Shi Lei, saying that Shi Lei was trying to get into trouble again and thinking about some issues too complicatedly.
Shi Lei wondered: "What do you mean?"
"Brother Shitou, do you know about motorboats?" Li Guai explained the information about motorboats, "Currently, the speed of some high-speed motorboats has reached 180 kilometers per hour. However, this is not the ultimate speed of motorboats. After
Specially modified motorboats, for example, in 1978, an Australian used a motorboat equipped with a jet engine and ran a super speed of 511 kilometers per hour!"
"Nah! 511 kilometers per hour?" Shi Lei was shocked!
However, if a jet engine is used, and there are no traffic rules or obstacles on the sea, a motorboat can sail at will. Therefore, a speed of 511 kilometers per hour is not impossible.
"That's right! Brother Shitou, in fact, at this speed, the motorboat is not sailing on the sea, but moving forward in a way similar to jumping and flying." Li Chai explained.
It is precisely because of this jumping and flying method that the motorboat can create extremely fast speeds. Otherwise, how could it really reach a speed of 511 kilometers per hour when sailing on the sea?
"Xiao Lizi, what do you mean, we develop a vessel similar to a motorboat?" Shi Lei somewhat understood what Li Guai meant. If they can develop an ultra-high-speed sea navigation vessel, it will be useful for detecting n235 metal and subsequent minerals.
Armed protection on land and sea will provide quite reliable convenience.
"Almost! However, we don't use the shape of a motorboat. The overall shape of the motorboat is not good, and the wind and wave resistance, stability, and internal space cannot meet our requirements." Li Chai denied the structure of the motorboat.
"No problem! Xiao Lizi, you can take care of it yourself!" Shi Lei said with authority.
Shi Lei is a novice in mechanical design. The task of designing an ultra-high-speed armed unmanned patrol boat can only be left to Li Chai.
"Brother Shitou, I plan to design the armed unmanned patrol boat into a spindle shape, use a fully enclosed hull, and install a turbojet engine." Li Guai explained simply.
In order for Shi Lei to better understand what he meant, Li Chai began to describe the specific appearance of the armed unmanned patrol boat, "Brother Shitou, what I call a spindle shape is roughly like this. In your mind, construct a square ABCD.
First, take point d as the center of the circle and ad as the radius, and draw an arc clockwise; then take point b as the center and bc as the radius, and similarly draw an arc clockwise. The two arcs and the square form two quarter circles,
The intersection of the two quarter circles is the hull shape of the armed unmanned patrol boat I plan to design."
Shi Lei imagined the pattern described by Li Cai in his mind. Although the pattern seemed a bit complicated to imagine out of thin air, it was not difficult for Shi Lei. This was not Shi Lei's Tai Niu coin, but Yizuer's synchronization on the laptop screen.
, and drew the geometric pattern described by Li Chai.
"Brother Shitou, if we want to ensure the ultra-high speed of the armed unmanned patrol boat, then we can only design the hull of the armed unmanned patrol boat to be slightly smaller." Li Guai explained the situation.
"Uh, why?" If the armed unmanned patrol boat is designed to be too small, the range and weapon-carrying capabilities of the armed unmanned patrol boat will be significantly reduced.
This situation was not what Shi Lei was happy to see.
Li Chai patiently explained to the mechanical novice, "Brother Shitou, the armed unmanned patrol boat we designed is mainly used for ocean navigation. The winds and waves are high in the ocean waters, and our armed unmanned patrol boat needs to sail at ultra-high speeds.
.If the hull is too big, it may be broken in half by wind and waves."
According to Li Chai's design, if the spindle-shaped hull is too long and too large, it may indeed break in the middle. Even if it can withstand wind and waves, it cannot withstand the huge force of super high speed. Especially when it suddenly changes direction, the powerful
Inertia easily destroyed the hull.
"Understood!" Shi Lei nodded. "Little Liz, what do you think the maximum size of the armed unmanned patrol boat can be?"
Li Guai was thinking about the specific situation in his mind, "Brother Shitou, how do you plan to position the armed unmanned patrol boat? A victim like the first-generation Steel, or a cutting-edge combat force like the second-generation Dawner.
?”
"This... Xiao Lizi, is there such a big difference in combat effectiveness between different designs of armed unmanned patrol boats?" Shi Lei asked again in confusion. There is no comparability between the first-generation Steel and the second-generation Dawner.
Bar?
Simply put, if the first-generation Steel was not equipped with missiles, then even if a thousand first-generation Steel were in head-to-head combat with the second-generation Dawners, the second-generation Dawners could easily win.
The combat effectiveness of the two is completely different. It's like hitting a rock with eggs. How many eggs are needed to break the rock?
"It's a big difference! Brother Shitou, if the armed unmanned patrol boat is used like cannon fodder, then the hull size of the armed unmanned patrol boat is not an important factor. We need to consider the simplicity of the manufacturing process and the control
Reduce manufacturing costs." Li Chai described the low-cost and crudely made armed unmanned patrol boats. "The cannon fodder version of the armed unmanned patrol boats can only be equipped with a heavy machine gun or even a light machine gun at most."
Shi Lei frowned, "Isn't this a little too shabby?"
"There is also a mid-range version! The hull size can be controlled at about three meters, and the speed should be able to reach 200 to 300 kilometers per hour. You can also choose wheel-barrel machine guns, or small ship-to-air and ship-to-ship weapons.
In terms of missile power, you can choose a fuel-fired small turbojet engine. The estimated range should be more than two thousand kilometers." Li guessed the second option.
Shi Lei was still not satisfied.
Shi Lei was not satisfied with the ship's weapons, sailing speed, or range.
"Xiao Lizi, this plan doesn't work either!" Shi Lei rejected Li Guai's plan.
Li Chai seemed to have expected it, "Brother Shitou, there is still a final plan. We directly design an electric plan and use new energy design. In this way, we can further reduce the hull. At the same time, after the hull is reduced, whether it is to resist wind and waves,
Ability, ability to avoid attacks, or sailing speed will all be greatly improved. Not only that, after using new energy, we can also apply the third-generation electromagnetic gun to the hull to ensure armed unmanned patrols
The boat has a powerful enough attack."
Li Chai paused for a moment and continued: "Brother Shitou, if we adopt a new energy solution, the design materials of the hull will be better. Even, because the hull is small enough, we can choose a strong integrated hull!"
The integrated hull is structurally stronger and is definitely better than the modular design in terms of anti-torsion and anti-collision capabilities.
Of course, this is not to say that modular design is bad!
Both integrated molding design and modular design have their own advantages. Which one is better or worse requires different comparisons under different circumstances.
The second generation Dawn Walker adopts a standard modular design. If the second generation Dawn Walker adopts an integrated molding design, then the second generation Dawn Walker will not be a metal exoskeleton, but a metal statue.
If the hull of an armed unmanned patrol boat adopts a modular design, when resisting twisting and impact, the hull will be more likely to be damaged due to uneven stress between modules.
Therefore, the hull of the armed unmanned patrol boat is more suitable for an integrated molding design!
Shi Lei was a little hesitant about the direct use of new energy design plans. The reduction in n235 metal production on Meishan Island made Shi Lei understand that n235 metal is a rare energy source and is not a pebble for him to ask for.
Once the n235 metal veins on Meishan Island are mined and Shi Lei discovers new n235 metal veins, the n235 metal will exist as a semi-consumable.
The so-called semi-consumable is because n235 metal can be charged in the reverse direction. However, reverse charging is really tricky. It takes almost ten times the released energy to restore the energy inside the n235 metal.
Once n235 metal activates the second-stage application plan, reverse charging is simply unrealistic. Unless Shi Lei activates the third-stage application plan of n235 metal. Then use the n235 metal in the third-stage application plan to release a huge amount of energy.
The energy is used to charge the n235 metal used in the second stage application plan.
Then until the fifth stage, n235 metal has completely become an irrecoverable consumable!
As n235 metal is a semi-consumable product, Shi Lei was reluctant to apply n235 metal to armed unmanned patrol boats because he wanted to save as much as possible.
After all, if something unexpected happens to the armed unmanned patrol boat, the related ultra-high-speed multi-frequency current exciter will definitely sink to the bottom of the sea. It is probably very difficult to salvage the ultra-high-speed multi-frequency current exciter in the sea.
"Xiao Lizi, are there any other alternatives?" Shi Lei wanted a solution that had the best of both worlds, one that would not use n235 metal but also have strong combat effectiveness.
