A golden slime lay softly on Charles's head, and followed him around the Cam Ranh Bay Naval Base to inspect the work.

Although Tilby House is not reliable when it comes to artistic creation, this time he was beaten by his sister and then sealed into a slime form for three days, but the usual work can still be completed perfectly, and the base is in good order. , a harmony.

Finally, Charles climbed to the top of the mountain in the west of the base, where you can get a bird's-eye view of the whole bay.

This bay is surrounded by mountains of different heights, and the sea is in the shape of a "∝" like a gourd. The inner bay covers an area of ​​nearly 100 square kilometers, with a water depth of 10 to 20 meters. The channel connecting the outer bay to the east is about two kilometers wide. The mouth of the outer bay is about 6 kilometers wide and more than 40 meters deep. It is a rare and excellent port.

Now the whole bay is surrounded by a huge construction site, a newly repaired railway branch is bringing in all kinds of raw materials and equipment, and the Naval Academy, steel factory, machine shop, shipyard and affiliated cities are stepping up the construction.

In the near future, after the completion of these colleges and factories, the construction of the first steel warship on this continent, the Type 037 Yellow Water Battleship, will begin here.

To this end, all the old men in the Naval Nursing Home went to work at various construction sites to ensure that the project was completed on schedule with quality and quantity.

Charles found a stone and sat down, then took the Tilby House above his head and held it in his arms.

"Ah..." Tilby sighed deeply.

Charles patted him and said, "Don't sigh, take a lesson, and don't doodle again in the future."

"It's not because of this that I sigh." Tilbi said, "If it weren't for those evil gods, we would have built a giant steel ship long ago, and now we can even go to other planets."

"Thanks to the information provided by Panpan's boss, everyone can speed up now."

Charles nodded. If it weren't for the golden finger sent by Mr. Zhang, the Rurik Kingdom would still be at the stage of accumulating experience in manufacturing inland iron ships.

With the excavation and research of materials from other worlds, the ambitions of the relevant departments of the Rurik Kingdom have grown, including imitating the Type 037 Yellow Water battleship with reference to blueprints.

The reason why he chose to imitate it is because there are only simple drawings of this type of warship in those materials, and Mr. Zhang Lu Ziye is not wild enough to get a full set of drawings of the warship, which is probably his limit.

On the army side, Mr. Zhang gave a simple drawing of the Type 59 tank, but Charles hoped that what he sent was an ordinary armored vehicle, at least the technical difficulty was not that big. Moreover, the main opponent of the main battle tank is the enemy's tank. If you take out the tank and fight who will go, it is better to install a quadruple-mounted Gatling behind the small pickup. It is practical to open a row to increase the distance. Even Arturia was about to run. Therefore, the military's current focus on its imitation is on the chassis. In a short period of time, it is estimated that a few cars will be built in the Abyss City as an honor guard. It is almost the same as pulling it out to show off and sell the surrounding during the festival, and it is still a water pipe to act as a tank gun. But Charles still really wanted to put two of them at the gate of the White House to ward off evil spirits.

There are no ready-made weapon blueprints on the Air Force side. The blueprints for the Yun-5 and some information on jet engines are given. After all, the technical content of the aircraft is too high, and the pace is too big.

There is no way to copy these drawings. Now all 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 technologies.

For example, the power system of the Type 037 Yellow Water battleship has been arguing for a long time. Some people think that the internal combustion engine-propeller system is safer according to the drawings, and some think that the water jet propulsion is more advanced and suitable.

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

Then he sided with the water jet propulsion system, which he believed was simple in structure, easy to maintain, and superior to the internal combustion engine-propeller propulsion system for small boats.

With the support of the Admiral, the "Spitters" won.

Of course, the design of the hull has to be redone after the water jet propulsion is adopted, otherwise there will be a problem with the center of gravity, and the boat will stand up like a fish float when it is launched.

However, Charles also instructed that the research on large-scale internal combustion engines cannot be stopped, otherwise it will be over if the ship cannot get an engine when it is needed.

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

Charles returned to Abyss City to rest for two days after his work in the Navy. During this period, he went to the Lurica Engine Design Bureau to see if there were any new achievements in the recent engine development.

In a small conference room, he met Rurika and Braun, who had a relationship when the dragon presented him with a heavy medal, and many other bigwigs he didn't know.

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

With the development of technology, different engines have been put into use, and the advantages and disadvantages of these engines have begun to emerge.

The traditional blower-type wind turbine works well on the ground and at medium and low altitudes, but it is obviously underpowered when the air is thin at high altitudes.

Although the wind turbines of the elves that violently output a bunch of magic arrays in a confined space and then push the impeller to rotate do not have this problem, but the energy consumption is too high, it is not bad to use light equipment such as power delta wings, tricycles and motorcycles , but too much magic to use on trucks and transports. Now even the elves don't like it, and begin to turn to the use and research of internal combustion engines.

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

So during this time Rurik invited Braun, Klimov, Isotov, Soveloyev, Kolesov, Kuznetsov, Tumansky, Ivchenko, etc. The big names in the engine field discuss the development of a new generation of engines, targeting the upcoming passenger aircraft market.

Charles moved a chair and sat obediently in the corner. He seemed to be a student brought by the bigwigs just like the people around him, but the distinctive horns on his head immediately revealed his identity.

The question that everyone is discussing today is how to increase the thrust of the engine at high altitudes while reducing the weight gain as much as possible. The current idea is to let the engine spray more stuff, not just inhale the air from the front and then spray it out from the rear.

According to the formula for calculating the thrust of the aero-engine:

F=M?C?-M?C?+(Ps-Po)A

in

F: engine thrust;

M?: the mass flow rate of the gas flowing into the engine;

M?: mass flow rate of gas out of the engine;

C?: Airflow velocity into the engine;

C?: Airflow velocity out of the engine;

Ps tail nozzle outlet static pressure;

Po: atmospheric pressure;

A: The cross-sectional area of ​​the engine tail nozzle;

When the difference between Ps and Po is ignored,

then there are

F=M?*C?-M?*C?

Because now the air intake of the jet engine is the same as the jet volume, that is, M?=M?,

then there are

F=M?(C?-C?)

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

Because the mass flow rate is the mass of fluid passing through the cross section per unit time, the big guys started to make a fuss on M? to see if they could "add something to the engine" to achieve the purpose of ejecting additional substances from the nozzle.

Some people propose to add a magic array in the second half of the engine to add wind elements to the engine to increase the quality of the ejected material.

However, 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 will annihilate each other. If the engine is not out, it will return to the magic element. If the output is strong, it is not as good as It's cheap to tie a few rockets.

Others suggested not to confine your eyes to magic, there is oxygen in the air, and there is enough oxygen in the engine, so burn something in the engine to make the engine spew extra gas.

The question is, what to burn?

The fossil fuels in this world are only coal, oil and natural gas have not been discovered yet, and Reimu is not willing to help.

Then Braun said, "Would you like to try methane?"

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

"How is methane stored on a plane, please?" he asked.

At this time, someone started to calculate~www.wuxiaspot.com~ Assuming that the design pressure of the methane container is 5.5MPa, the design temperature is 50℃, and the service temperature of the steel plate is between -20℃~50℃, then the thickness of 42mm is used. 16MnR type special steel for pressure vessels.

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

Charles pinched his brows, hoping that the space expansion magic and weight loss magic of the spiritual masters would be more powerful, otherwise it would be difficult to handle.

Just as he thought, Ryurika, who presided over the meeting, announced that today is the end of the day. He will go to an expert named Shatalov to consult the prospect of space expansion magic used on aircraft, as well as the application of space expansion magic on pressure vessels. usage.
