Rising: Ten Thousand Years Chapter 292: : 4-stroke radial engine

A mobile academy.

The classroom is full of smoke.

Ever since I became a scientist and started working **** my brain, everyone found that it was really more tiring than physical work.

In just one or two years, many people in this classroom have gone bald.

Everyone is addicted to smoking. And alcoholism.

There is no way. Under the high-intensity scientific pressure, there are only two ways that everyone can think of to relieve the pressure.

There are fifty people sitting in the classroom, and twenty of them are carrying bongs in their hands. A common scene is holding a bag under the eye in the left hand and a pencil in the right.

Li Zhen stood in front of the blackboard:

"Who can tell the disadvantages of the airship?"

Ma Jianbin put a pencil on his ear, stood up and answered:

"Mr. Li, I personally think that the use of airships as war machines is actually a short-lived effect."

"Tell me why?"

"First of all, the hull of the airship is too large, the target is large, and the speed is slow. It is actually not suitable for use in warfare. The most important thing is that hydrogen is a flammable and explosive gas. If a long-range weapon is developed , hit on the ground. Then it only needs to rub and touch, and the airship will have a devastating disaster. The airship may achieve good results in the short term, but because the principle of the airship is too simple, I'm sure it won't take long , airships will also appear in other parts of the world.”

"Ma Jianbin, you are right. But these are not the biggest drawbacks of the airship."

Li Zhen said: "The biggest disadvantage of airships is their high cost. First, it is difficult to prepare hydrogen. Second, basically, once an airship is launched, it is a one-time operation. It can meet long-distance flights. But it cannot meet the needs of war. practical needs. Therefore, our next course is to develop another aircraft.”

"This time, the Institute of Aviation and the Institute of Maneuvering need to cooperate closely. In-depth exchanges. I have a vision. If this project is successfully developed, New Kyushu will completely become the overlord of aviation."

At this time, Liu Jinghong, the dean of the Academy of Aeronautics who was listening, stood up:

"Mr. Li. Regarding the new type of aircraft, the Aviation Academy has always had an idea. It was a vague concept before, but after the appearance of the airship, the idea gradually became clear."

"You say."

"Wingspan aircraft."

Liu Jinghong stepped onto the podium and talked eloquently: "We have passed the test. We installed a propeller on a small internal combustion engine, carried a person behind his back, and then hung a paraglider. It can take off directly from the flat bottom, and it is a true paraglider in the sky. Solo flight. This is a motorized paraglider."

Li Zhen nodded, he knew about it.

This is a topic they started after the airship came out. It is to prove whether the forward power can be converted into rising buoyancy. The experiment was a success.

That's how the real paraglider appeared.

Liu Jinghong said again: "Actually, after this step, we already have the second type of aircraft, which is the motorized paraglider. But the actual situation is that it cannot be used in war, nor can it be used in industry. Only It can meet individual needs. Its inability to fly long distances is also the biggest drawback. We have conceived and theoretically established a new aviation tool. We call it a wing-span aircraft.”

"The cockpit is set up through the main structure with wingspan. The internal combustion engine is used at the rear to obtain thrust. The whole body adopts a streamlined structure. After being pushed forward by the engine, the wings are inclined upwards, so that the upward power can be obtained. Successfully soared in In the air. The principle is not difficult, but practical technical problems require breakthroughs.”

Airplane!

Li Zhen's first reaction was ecstasy.

The idea of ​​an airplane arose. I have always known the structure of the plane before, but I feel that it is too difficult for them, and it is a feeling of reaching the sky in one step. It's not as stable as being down-to-earth. So I want to wait until the technological foundation has developed to a certain level before proposing it.

Unexpectedly, the progress of science is indeed linear. This idea was proposed by the people of the Aviation Academy.

Very good, wingspan aircraft.

Li Zhen asked: "What technical problem?"

"The first is the material problem. We need a lightweight material that is not only strong, but also has a certain degree of toughness. The most important thing is to be light. I have contacted people from the Institute of Materials Engineering, but they are temporarily unable to provide Such a material. We thought about using wood, but it was overthrown. Wood is not strong enough to withstand the weight of gravity carried by lift."

"The second is the power problem. The internal combustion engine of the airship is not enough to drive the wingspan aircraft we propose. We need a lighter, more powerful, and more stable internal combustion engine. The current internal combustion engine is often prone to stalling. And This hidden danger of flameout is a fatal blow to a wingspan aircraft.”

"Third, that is our design problem. But if this problem is put on the agenda for research, it can be overcome in a short time."

Li Zhen couldn't help thinking deeply, imagining the aviation planes of their era that Zhang Zhi described to himself, and a bold idea came to his mind.

Since it has really developed to this point. So why not put this on the agenda?

There are problems. There are many.

But no matter how difficult a problem is, it will always be overcome in the end.

Going from 0 to 1 is the hardest. But from 1 to 1000, it is simple.

Recalling that I didn't know anything ~IndoMTL.com~ and just figured out the steam engine. Starting from the steam engine, the entire Kyushu immediately changed with each passing day, and changes occurred every day. This is the progression from 0 to 1.

The difficulty of the aviation plane seems to be 1000, not to eat a fat man in one bite. Only groping.

"That's it. Regarding the new internal combustion engine, I have an idea for you to study."

As soon as this remark came out, everyone in the classroom sat up straight and pricked up their ears.

Li Zhen took out a piece of chalk, faced the blackboard, closed his eyes and remained silent for a long time. I went through what Zhang Zhi described in my mind, and then relied on my imagination to draw a three-dimensional schematic diagram in my mind.

He raised his hand and began to draw on the blackboard.

About half an hour later, an extremely intricate drawing appeared on the blackboard. From a distance, you think this painting looks like a sun that radiates light.

But if you look closely, you will find that it is a disc in the middle. And the surrounding circle is full of outgoing pistons.

Look carefully. do not understand.

"This is..."

Ma Jianbin stepped onto the podium and watched closely for a long time, feeling puzzled.

Li Zhen threw away the chalk, pointed to something on the blackboard, and said loudly:

"Four-stroke radial reciprocating engine!"

All the members of the class exploded immediately, talking a lot.

Just hearing this name, I feel unclear. Nervous, apprehensive.

For the people in the Motor Academy, there is nothing more exciting than a breakthrough in engine technology.

People in the world say that when the bridal chamber is festive and candle night, when the gold list is named, life is a great joy.

But for them, the greatest joy in life is to listen to Li Chen put forward one new concept after another.
