HK1240 Different Plans, Worlds Apart!

In nature, there is a theorem that the greater the resistance an object receives, the more difficult it is to obtain a faster speed.

In the ocean, for example, the speed of a submarine is hardly comparable to that of a ship. Because the resistance of sea water is very large, it is not an easy thing to sail at high speed in sea water.

In the same way, although the ship sails on the sea, the resistance of the sea water is slightly smaller, but it is definitely not as small as the air resistance. It is not easy for a ship on the sea to be faster than an aircraft, even a miniaturized remote-controlled unmanned helicopter.

"Brother Shitou, you've fallen into a misunderstanding!" Li Gues reminded Shi Lei, saying that Shi Lei was thinking too much about some problems again.

Shi Lei asked in confusion, "What do you mean?"

"Brother Stone, do you know about motorboats?" Li guess explained the information of motorboats. "At present, the speed of some high-speed motorboats has reached 180 kilometers per hour. However, this is not the limit speed of motorboats. After Specially modified motorboats, for example, in 1978, an Australian, using a motorboat with a jet engine, ran a super speed of 511 kilometers per hour!"

"Nima! 511 kilometers per hour?" Shi Lei was shocked!

However, if a jet engine is used, and there are no traffic rules and no obstacles on the surface, it is completely free to sail for a motorboat. Therefore, the speed of 511 kilometers per hour is not impossible.

"That's right! Brother Stone, actually at this speed. The motorboat is not sailing on the sea, but moving forward in a way similar to jumping flight." Li Guai explained.

It is precisely because of this way of jumping and flying that the motorboat can create extremely fast speeds. otherwise. Really sailing on the sea, how can it reach a speed of 511 kilometers per hour?

"Little Lizi, do you mean that we will develop a boat similar to a motorboat?" Shi Lei understands what Li guess means. If they can develop a super-high-speed sea-going boat, it will be useful for detecting n235 metal and subsequent minerals. Armed protection at sea. will provide fairly reliable convenience.

"Almost! However, we don't use the shape of the motorboat. The overall shape of the motorboat is not good, and the wind and wave resistance and stability. And the internal space cannot meet our requirements." Li guess denied the structure of the motorboat.

"No problem! Little Lizi, you can do it yourself!" Shi Lei said in a relaxed manner.

Shi Lei was a novice in mechanical design, and the work of designing ultra-high-speed armed unmanned patrol boats could only be left to Li Guai.

"Brother Stone. I plan to use an armed unmanned patrol boat. It is designed in a spindle shape, with a fully enclosed hull and a turbojet engine." Li Guai explained briefly.

In order for Shi Lei to better understand what he meant, Li guess began to describe the specific shape of the armed unmanned patrol boat, "Brother Shi, what I call a spindle shape is about this appearance. In your mind, construct a square abcd. First, take point d as the center. Ad is the radius, and make a clockwise arc; then take b as the center. bc is the radius, and also make the 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 Guess in his mind. Although this pattern was a bit complicated to think of out of thin air, it was not difficult for Shi Lei. This is not Shi Lei's bull coin, but Yizuer synchronizing on the notebook screen, drawing the geometric pattern described by Li Guai.

"Brother Stone, if we want to ensure the ultra-high speed of the armed unmanned patrol boat, we can only design the hull of the armed unmanned patrol boat to be slightly smaller." Li Gu explained the situation.

"Uh, why?" If the armed unmanned patrol boat is designed to be too small, the range of the armed unmanned patrol boat and the ability to carry weapons will be greatly reduced.

This situation was not something Shi Lei would like to see.

Li Guai patiently explained to Mechanic Xiaobai, "Brother Shito, the armed unmanned patrol boat we designed is mainly used in ocean-going sailing. The wind and waves are high in ocean-going waters, and our armed unmanned patrol boat needs ultra-high speed sailing. .If the hull is too big, I'm afraid it will be snapped in half by the wind and waves."

According to Li guess'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 the wind and waves, it cannot withstand the huge power of super high speed. Especially when suddenly changing direction, the strong inertia can easily kill the hull.

"Understood!" Shi Lei nodded. "Little Lizi, what is the maximum size of the armed unmanned patrol boat, what do you estimate it can be?"

Li guess pondered the specific situation in his mind, "Brother Stone, how do you plan to position the armed unmanned patrol boat? A victim like the first generation of Steel, or a cutting-edge combat force like the second generation of Dawn ?"

"This... Little Lizi, is there such a big difference in the combat effectiveness of the different designs of the armed unmanned patrol boat?" Shi Lei asked again incomprehensibly. The first generation of Steel and the second generation of Dawner are completely incomparable, right?

To put it simply, if the first generation of Steel, there are no missiles on board. Then, even if a thousand first-generation steel fighters fought head-to-head with the second-generation Dawning, the second-generation Dawning could easily win.

The combat power of the two is not at the same level at all. It's like hitting a stone with an egg. How many eggs do you need to break the stone?

"The difference is very big! Brother Shi, if the armed unmanned patrol boat is used as 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 manufactured armed unmanned patrol boats. "The cannon fodder version of the armed unmanned patrol boat can at most carry a heavy machine gun, or even a light machine gun."

Shi Lei frowned, "Is this 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. The weapons carried can also choose wheel-barreled machine guns, or small ship-to-air and ship-to-ship. Missiles. In terms of power, you can choose a fuel version of a small turbojet engine. It is expected that the range should be more than 2,000 kilometers." Li Gu said the second option.

Shi Lei was still not satisfied.

Shi Lei was not satisfied with ship-borne weapons, sailing speed, or range.

"Little Lizi, this plan doesn't work either!" Shi Lei rejected Li Gu's plan.

Li Guai seems to have anticipated it long ago, "Brother Stone, there is still a final plan. We directly design the electric energy scheme 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 wind-resistant The ability, the ability to evade attacks, or the 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 patrolling. boat, with a sufficiently powerful attack."

Li Guai paused for a while and continued: "Brother Shito, if we adopt a new energy solution, the design material of the hull will be better. Even, because the hull is small enough, we can choose a solid integrated hull!"

The integrated hull is stronger in structure, and it is definitely better than the modular design in terms of anti-torsion ability and anti-collision ability.

Of course, this is not to say that modular design is bad!

Whether it is an integrated molding design or a modular design, it has its own advantages. Which is better and which is worse, needs to be compared in different situations.

The second-generation Dawner adopts the standard modular design. If the second-generation Dawner adopts an integrated molding design, then the second-generation Dawner is not a metal exoskeleton, but a metal statue.

If the hull of the armed unmanned patrol boat adopts a modular design, when resisting distortion and impact, the hull will be more easily damaged due to uneven force between the modules.

Therefore, the hull of the armed unmanned patrol boat is more suitable for the integrated molding design!

Shi Lei was hesitant to use the new energy design directly. The reduction in the production of n235 metal on Meishan Island made Shi Lei understand that n235 metal is a rare energy source, not a pebble that he can ask for.

Once the n235 metal veins of Meishan Island are mined, and whether Shi Lei has discovered new n235 metal veins, the n235 metal will exist as a semi-consumable.

The so-called semi-consumable, that is because the n235 metal can be reversely charged. However, reverse charging is too tricky, and it takes almost ten times the released energy to restore the energy inside the n235 metal.

Once the n235 metal opens the second-stage application scheme, reverse charging or something is simply unrealistic. Unless, Shi Lei opened the third-stage application scheme of n235 metal. Then use the n235 metal of the third-stage application scheme to release a huge amount of energy to charge the n235 metal used in the second-stage application scheme.

Then until the fifth stage, the n235 metal was completely reduced to an irrecoverable consumable!

As a semi-consumable n235 metal, Shi Lei is not willing to apply n235 metal to armed unmanned patrol boats because of the idea of ​​saving.

After all, once an accident 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 very difficult to salvage ultra-high-speed multi-frequency current exciters in the sea.

"Little Lizi, are there any other alternatives?" Shi Lei wanted a solution that had the best of both worlds, which would not only use n235 metal, but also have strong combat power.
