The Troublesome Hero Among the Heroes

A golden slime lay softly on Charles' head, and followed him around in the Cam Ranh Bay naval base to inspect work.

Although Tilby House was unreliable when he encountered artistic creation, this time he was beaten by an elder sister and then sealed into a slime form for three days, but his work was normally perfect. Completed, the base is well organized and harmonious.

In the end, Charles climbed to the top of the high mountain west of the base, where you can have a bird's eye view of the entire bay.

This bay is surrounded by mountains of different heights. The sea surface is like a bottle gourd in a "∝" shape. The inner bay covers an area of ​​nearly 100 square kilometers with a water depth of ten to twenty meters. The channel connecting the bay is about two kilometers wide, and the mouth of the outer bay is about six kilometers wide and the water depth is more than 40 meters. It is a rare and excellent port.

Now the entire bay is surrounded by a huge construction site, a newly repaired railway branch line is continuously transporting various raw materials and equipment, the Navy Academy, steel plants, machinery plants, shipyards and affiliated cities Construction is stepping up.

In the near future, after these academies and factories are completed, construction of the first steel battleship on this continent, the Type 037 Yellowwater Battleship, will begin here.

For this goal, the old fogeys in the Naval Nursing Home have all gone to various construction sites to ensure that the quality and quantity of the project are completed on time.

Charles found a rock and sat down, then took the Tilby house above his head and hugged it in his arms.

"Oh..." Tilby's house sighed long.

Charles patted Him, and said: "Don't sigh, accept the lesson, and don't scribble again in the future."

"I sighed not because of this." Tilby House said. "If it weren't for those fucking Evil God, we could have built a giant steel ship, and now even other planets can go."

"Fortunately, I am looking forward to the information provided by his boss. Now everyone can speed up Steps."

Charles nodded, if it weren’t for the cheat sent by Mrs. Old Zhang, the Rurik Kingdom is still at the stage of building inland iron ships to accumulate experience.

With the excavation and research of the materials from the foreign world, the ambitions of the relevant departments of the Rurik Kingdom are getting bigger and bigger, including referring to the blueprint to imitate the Type 037 yellow water battleship.

The reason why I chose to imitate it is that there is only the simple blueprint of this warship in those data. Old Zhang's grandfather Lu Ziye is not wild enough to get the full set of blueprints of the warship. This is probably his limit. NS.

On the army side, Mr. Old Zhang presented a simple blueprint of the Type 59 tank, but Charles hoped that he would give it an ordinary armored vehicle. At least the technical difficulty is not that great. And the main opponent of the main battle tank is the enemy's tank. Now if you get the tank out to fight who will go, it is better to install a quadruple Gatling behind the Little Pi card, and open it to open the distance "da da da" Even Altria has to run. Therefore, the military currently focuses on its imitation on the chassis. In a short time, it is estimated that the entire car will be built to put the Abyss City as a guard of honor. Tank gun. But Charles still wanted to put two at the door of the White House to ward off evil spirits.

The Air Force doesn’t have any ready-made weapons blueprints. The blueprints for Yun-5 are given, and there are some jet engine information. After all, the technical content of the aircraft is too high and the steps are too big.

There is no way to copy these blueprints. At present, various research departments are actively researching, refining and optimizing the design, to see which places can be copied and used for reference, and those that need to be replaced with local technology.

For example, we have been arguing for a long time because of the power system of the Type 037 Yellowwater Battleship. Some people think that it is safer to use the internal combustion engine-propeller system according to the blueprint, and some think that the water jet is used. More advanced and more suitable.

Charles was arrested two days ago when he was still in Abyss City, because he presided over the research of the Shield Bridge Academy water jet racing, and a group of experts asked him to talk about which system is good.

Then he stood on the side of the water jet. He believed that this propulsion system was simple in structure and easy to maintain, and it was better than the internal combustion engine-the propeller propulsion system on small ships.

With the support of the admiral, the "sprayers" won.

Of course, the design of the hull has to be re-designed after the water jet is adopted, otherwise the center of gravity will go wrong, and the boat will be funny if it is launched into the water and stood up like a fish float.

However, Charles also instructed that the research on large internal combustion engines should not be stopped, otherwise the engine would be ruined if the ship is too big and needed.

There are many similar things in the field of technical research.

Charles returned to Abyss City for a two-day rest after finishing his naval work. During this period, he went to the Lulica Engine Design Bureau to see if there were any new results in recent engine development.

In a small Conference Hall, he met Rulika and Braun, who had a fate when he was awarded a medal by a giant dragon, and there were many big names he didn’t know. guy.

At this time, the big guys are discussing the improvement of the engine.

With the development of technology, different engines are put into use, and the advantages and disadvantages of these engines are beginning to be revealed.

Traditional blower-type wind turbines work well on the ground and at low and medium altitudes, but the power is obviously insufficient when the air is thin at high altitudes.

Although the Spirit Race type of wind turbines that violently output a bunch of magic arrays in a confined space and then push the impellers to rotate does not have this problem, the energy consumption is too high, and it is used to drive power delta wings and tricycles. Lightweight equipment like motorcycles is fine, but it consumes too much magic power to use on trucks and transport planes. Now even the elves don't wait to see it, and they start to use and study the internal combustion engine.

The internal combustion engine is good. It has developed rapidly in the past two years. There is a trend to kick wind turbines out of the market in the field of vehicle engines.

So during this time, Lilika invited Braun, Klimov, Isotov, Saviloyev, Kolesov, Kuznetsov, Tumans Big names in the engine field such as Kyrgyzstan and Ivchenko are discussing the development of a new generation of engines, with the goal of the upcoming passenger aircraft market.

Charles moved a chair and sat down in the corner. It looked like the people around him were students brought by the big guys, but the distinctive horns on his head were immediately exposed. His identity.

The question everyone discussed today is how to increase the thrust of the engine at high altitude while reducing the weight gain as much as possible. Squirting from the back.

According to the calculation formula of aero engine thrust:

F=M₂C₂-M₁C₁+(Ps-Po)A

where

F : Engine thrust;

M₁: Gas physique flow rate into the engine;

M₂: Gas physique flow rate out of the engine;

C₁: Inflow The airflow speed of the engine;

C₂: The airflow speed out of the engine;

Static pressure at the exit of the Ps tail nozzle;

Po: Atmospheric pressure;

A: Engine tail nozzle cross-sectional area;

When the difference between Ps and Po is neglected,

There is

F=M₂*C₂- M₁*C₁

Because the air intake volume of the jet engine is the same as the air injection volume, that is, M₂=M₁,

there are

F=M₁(C₂ -C₁)

So everyone has been making a fuss about the difference in air velocity, but the potential of this piece is now reaching its limit.

Because the mass flow rate is the amount of flow physique passing through the cross section per unit time, the big guys started to make a fuss about M₂ to see if they could “add something to the engine” to achieve the nozzle ejection. The qualitative purpose of the foreign object.

Someone proposed to add a magic array in the second half of the engine and add Wind Element to the engine to increase the mass of the ejected material.

But after some calculations, everyone found that the theoretical effect of this method is not ideal. The main reason is that the gases formed by the magic elements collide with each other in the high-speed airflow and annihilate each other, and they will return to the magic elements without the engine. However, it is better to tie a few rockets with a few rockets if you want to output vigorously.

Someone suggested not to limit your eyes to magic. The air contains oxygen, and the oxygen in the engine is sufficient. Then burn something in the engine to let the engine spray extra gas.

The question is here, what should I burn?

The only fossil fuels in this world are coal, oil and natural gas, etc. So far, Reimu is unwilling to look for them.

At this time, Braun said, "Why don't you try methane?"

Charles on the side heard a black line. Is this going to install the rocket engine on the plane?

He asked: "How do I store methane on the plane?"

Someone started to calculate at this time, assuming that the design pressure of the methane container is 5.5MPa and the design temperature is 50℃, the service temperature of the steel plate is between -20℃~50℃, then the 42mm thick 16MnR special steel for pressure vessels is used.

Assuming that the container is a cylinder with a diameter of 2000 mm and a height of 5000 mm, with standard elliptical heads at both ends, the container can hold about 221 mm of methane. The total weight of the entire container plus accessories and methane exceeds 12 tons.

Charles squeezed his brows, hoping to say that Spirit Masters have more space expansion magic and weight loss magic, otherwise it would be difficult to handle.

As he thought, Rurika, who presided over the meeting, announced that this is the end of the day. He is going to find an expert named Shatalov to ask about the prospects of space expansion magic on aircraft. , And the use of pressure vessels.
