Chapter 1186

.

In the natural world, there was a theorem that stated that the greater the resistance, the harder it was for an object to achieve a higher speed.

For example, in the sea, the speed of a submarine could not be compared to that of a ship. Because of the high resistance of the sea, it was not easy to travel at high speed in the sea.

Similarly, although the resistance of a ship sailing on the sea was slightly smaller, it was definitely not as small as air resistance. It was not easy for a ship to be faster than an aircraft, even if it was a miniaturized remotely piloted drone.

"Stone Head, you're thinking the wrong way!" Li Chai reminded Shi Lei, indicating that Shi Lei was thinking too much and was overcomplicating the problem.

Shi Lei was puzzled. "What do you mean?"

"Stone Head, do you know about motorboats?" Li Chai explained the information about motorboats. "Currently, the speed of some high-speed motorboats has reached 635 kilometers per hour. However, this is not the maximum speed of a motorboat. For example, in 6423, an Australian used a motorboat with a jet engine and reached a super speed of 066 kilometers per hour! "

"F * ck! 066 kilometers per hour? "Shi Lei was shocked!

However, if a jet engine was used, coupled with the fact that there were no traffic regulations on the sea, there were no obstacles. For a motorboat, it could travel freely. Therefore, a speed of 066 kilometers per hour was not impossible.

"That's right! Brother Stone, at this speed, the motorboat isn't sailing on the surface of the sea. Instead, it's advancing by leaps and bounds. "Li Cai explained.

It was because of this jumping that the motorboat could achieve such a high speed. Otherwise, how could it reach a speed of 066 kilometers per hour on the sea?

"Little Li, you mean that we should develop a type of boat similar to a motorboat?" Shi Lei somewhat understood Li Chai's meaning. If they could develop a type of super high speed ship, it would provide a rather reliable convenience for the detection of N780 metal, as well as the subsequent armed protection of the mines.

"Something like that! However, we will not use the motorboat model. The overall shape of the motorboat is not good. Wind and wave resistance, stability, and internal space cannot meet our requirements. "Li Chai rejected the structure of the motorboat.

"No problem! Little Li, do as you see fit! "Shi Lei delegated his authority and said.

Shi Lei was a novice in mechanical design, so he could only leave the task of designing the high-speed armed unmanned patrol boat to Li Chai.

"Stone Head, I plan to design the armed unmanned patrol boat in the shape of a spindle. It will use a fully enclosed hull and install a turbojet engine," Li Chai explained simply.

In order to let Shi Lei better understand what he meant, Li Chai began to describe the specific shape of the armed drone. "Stone Head, my so-called spindle shape is about this appearance. You construct a square ABCD in your mind. First, with point D as the center and AD as the radius, make a clockwise arc. Then with point B as the center and BC as the radius, make a clockwise arc as well. The two arcs and the square form two quarter-circles. The intersection of the two quarter-circles will be the hull shape of the armed unmanned patrol boat that I plan to design. "

Shi Lei imagined the pattern described by Li Chai in his mind. Although the pattern was a bit complicated, for Shi Lei, it was not difficult at all. It was not that Shi Lei was too awesome, but that Izur had synchronized the geometric pattern described by Li Chai on the laptop screen.

"Stone Head, if we want to ensure the speed of the armed drone patrol boat, we can only design the hull of the armed drone patrol boat to be slightly smaller." Li Chai explained the situation.

"Uhh, why?" If the armed drone patrol boat was designed to be too small, then the armed drone patrol boat's range and ability to carry weapons would be greatly reduced.

This situation was not what Shi Lei wanted to see.

Li Chai patiently explained to Mechanical Whitey, "Stone Head, the armed drone patrol boat we designed is mainly used for ocean navigation. In the ocean, the wind is strong and the waves are high, and our armed drone patrol boat needs to travel at super high speed. If the hull is too big, I'm afraid it will be broken in half by the wind and waves. "

According to Li Chai's design, if the spindle shaped hull was too long and too big, it could indeed break in the middle. Even if it could withstand the wind and waves, it could not withstand the huge force of the super high speed. Especially when it suddenly changed direction, the strong inertia could easily destroy the hull.

"Understood!" Shi Lei nodded. "Little Li, what do you think the maximum size of the armed drone patrol boat can reach?"

Li Chai thought about the specific situation in his mind, "Stone Head, about the armed drone patrol boat, how do you plan to position it? Like the first generation of the Iron Ship, a sacrifice, or like the second generation of The First Light, a sophisticated combat force? "

"This … Little Li, is there such a big difference between the different designs of the armed drone patrol boat?" Shi Lei asked again, not understanding. The first generation of the Iron Ship and the second generation of The First Light were completely incomparable, right?

Simply put, if the first generation of the Iron Ship did not carry missiles. Then, even if there were a thousand of the first generation of the Iron Ship and the second generation of The First Light in a head-on battle, the second generation of The First Light could easily win.

The combat power of the two was on a completely different level. It was like using eggs to smash a stone. How many eggs would it take to smash the stone?

"The difference is huge! Stone Head, if the armed drone patrol boat is used as cannon fodder. Then, the size of the armed drone patrol boat is not an important factor. We need to consider the simplicity of the manufacturing process, as well as the control to reduce the manufacturing cost. "Li Chai described the low-cost and crude armed drone patrol boat. "The cannon fodder version of the armed drone patrol boat can at most carry a heavy machine gun, or even a light machine gun."

Shi Lei frowned, "Isn't this a bit too shabby?"

"There is also a mid-range version! The hull size can be controlled to about three meters, and the speed should be able to reach 755 to 855 kilometers per hour. The weapon carried can also be a wheel-barreled machine gun, or a ship-to-air or ship-to-ship small missile. In terms of power, the fuel version of a small turbojet engine can be chosen. The estimated range should be more than 7,555 kilometers. "Li Chai proposed the second plan.

Shi Lei was still not satisfied.

Whether it was the ship's weapons, the speed, or the range, Shi Lei was not satisfied.

"Little Li Chai, this plan also won't work!" Shi Lei rejected Li Chai's plan.

Li Chai seemed to have expected this, "Stone Head, there is a final plan. We can directly design the electric design, using the new energy source. This way, we can further shrink the hull. At the same time, after the hull is shrunk, whether it is the ability to resist wind and waves, the ability to avoid attacks, or the speed, all will be greatly improved. Not only that, after using the new energy source, we can also apply the third generation electromagnetic cannon to the hull, ensuring that the armed drone patrol boat has a strong enough attack. "

Li Chai paused for a moment, then continued, "Stone Head, if we use the new energy source plan, the hull design material will be better. Because the hull is small enough, we can even choose a sturdy integrated hull! "

The integrated hull was structurally stronger. Whether it was the ability to resist distortion or impact, it was definitely better than the modular design.

Of course, this did not mean that the modular design was not good!

Whether it was the integrated design or the modular design, they both had their own advantages. To determine which was better and which was worse, they needed to be compared under different circumstances.

The second generation The First Light used the standard modular design. If the second generation The First Light used the integrated design, then the second generation The First Light would not be a metal exoskeleton, but a metal statue.

If the hull of the armed drone patrol boat was designed with a modular design, when resisting distortion and impact, the force between the modules would be uneven, and it would be easier to cause damage to the hull.

Therefore, the hull of the armed drone patrol boat was more suitable to use the integrated design!

Shi Lei was a little hesitant about directly using the new energy source design plan. The production of N780 metal on Mei Shan Island made Shi Lei understand that N780 metal was a rare energy source, not a cobblestone that he could freely use.

Once the N780 metal vein on Mei Shan Island was mined out, and Shi Lei did not find a new N780 metal vein, the N780 metal would exist as a semi-consumable.

The so-called semi-consumable was because the N780 metal could be charged in reverse. However, reverse charging was too much of a scam. It almost consumed ten times the released energy to restore the internal energy of the N780 metal.

Once the second stage of the N780 metal application plan was activated, reverse charging was simply not realistic. Unless Shi Lei activated the third stage of the N780 metal application plan. Then, the N780 metal in the third stage of the application plan would release a huge amount of energy to charge the N780 metal used in the second stage of the application plan.

Then, until the fifth stage, the N780 metal would completely become an irrecoverable consumable!

As a semi-consumable N780 metal, Shi Lei wanted to save as much as possible. He was not willing to use N780 metal on armed unmanned patrol boats.

After all, once the armed drone patrol boat had an accident, the related ultra-high-speed multi-frequency current exciter would definitely sink to the bottom of the sea. If he wanted to salvage the ultra-high-speed multi-frequency current exciter in the sea, it would be very difficult.

"Little Li, are there any other alternatives?" Shi Lei wanted the best of both worlds. He did not need to use the N780 metal, but also had a strong combat power.
