When leaving the Motor Vehicle Institute, Li Zhen found Jia Liping again and allocated another scientific research fund to the Motor Institute so that they could develop this new type of engine themselves.
Once this kind of engine is successful, it means that the Motor Vehicle Institute is completely on the right track. The meaning is very profound. It became the first institution to break away from Li Zhen and enter the independent research and development stage.
After coming out of the Mobile Academy, he entered the Aviation Research Institute.
Li Zhen really cares about planes that can fly into the sky. Because now New Kyushu is developing an air passenger transport project.
Mainly airships.
But in fact, airships are very troublesome, the cost is too high, and hydrogen is very difficult to collect. Fuel is still secondary. The most important thing is that hydrogen is too expensive and the load of the airship is very small.
It can only pull up to ten people at a time. It is only suitable for transporting VIPs, but is not suitable for developing civil aviation.
The aviation research institute is also under great pressure, because aircraft are the top priority. Whether New Kyushu can take the lead in entering the stage of civil aircraft depends on a group of talents from the Aviation Academy.
When Li Zhen came to the Aviation Academy, everyone put down their work and stood up to say hello to Li Zhen.
Li Zhen found Liu Jinghong: "Is there any progress?"
Liu Jinghong was a little excited: "There is progress. Now we have developed a new aircraft structure, which will be more suitable for flying. The finished product has been manufactured. We have towed it with a steam vehicle, calculated the horsepower, and compared it with the star. The thrust of the engine is more than enough to drive it to flight."
Li Zhen was a little surprised: "Oh? It was created? Where is it?"
Liu Jinghong quickly took Li Zhen into the courtyard of the Aviation Academy. Only high-level people have permission to enter this courtyard. Inside are all the core secrets of the Aviation Academy.
In the yard, a huge object was covered with canvas. Looking at the outline, it looks like an airplane.
Li Zhen was a little excited when someone went to uncover the canvas. A biplane made of wood as the main material appeared in front of Li Zhen.
It's very big, bigger than the biplane used in the previous experiment.
In addition, many changes have been made to the fuselage. The nose is sharper and the fuselage is more streamlined.
If you don't look at the wingspan and look at the fuselage alone, its appearance and shape are very much like a spur. A kind of bayonet with a very sharp front end and a larger point towards the back.
There are two seats in the middle, which can carry two people. This load should have been calculated by the two of them in advance, so that it will not cause imbalance and weight loss.
The airplane has three wheels, one at the front and two at the back.
The wingspan is larger and the structure is more stable.
In order to add strong stability, they added a lot of steel at the expense of some weight.
But the larger double-layer wingspan and slim fuselage make up for the lost weight.
After the last failure, the Aviation Academy conducted a deep introspection. The wingspan cable for adjusting the direction was replaced with a thumb-thick steel pipe.
It used to be a pull cord. But now it has become a lever principle, a mechanical steering structure that coexists with the mechanical principle.
The increase in weight is mainly due to the material used in the control system.
They painted the entire wooden aircraft with silver paint. From a distance, it looked like the metallic luster of fighter jets of that era. The slim and streamlined body looks even more psychedelic.
But Li Zhen was sure that this type of aircraft had never appeared in Zhang Zhi's era.
It has a slim fighter fuselage but a double wingspan.
It looks more sci-fi and psychedelic.
Li Zhen looked at the aircraft carefully and said with appreciation: "I feel that it should be possible. But there is a very serious problem that must be solved."
Liu Jinghong asked: "What's the problem?"
Li Zhen pointed to the pointed nose and said, "Where is the engine of the aircraft?"
Liu Jinghong said: "This is a breakthrough in our thinking. Our current preliminary decision is to install two radial engines on the wings. One on each side of the wings. The thrust is generated directly by the wingspan, neither Front-engine, not rear-engine, we’re trying to be mid-engine.”
Li Zhen frowned: "Two engines? Do you know how dangerous this is? If the power of the two engines is different, the flight will be unbalanced in the air."
Liu Jinghong nodded thoughtfully and said, "Yes, now we are preparing to deal with this key factor. We have thought of this, but we can only overcome it and solve it."
Li Zhen shook his head: "Let's change the plan. The current power system is not enough to support such a sophisticated idea."
Liu Jinghong was anxious: "But..."
"It's nothing. I know what you're thinking. You want to swallow a fat man in one bite. But science must be down-to-earth, and don't be too ambitious. Now the Kyushu Academy of Sciences does not have such sophisticated instruments, including mass-produced cars, each one The power is different. How can you guarantee an aircraft that requires higher precision?"
"Installing a power system on the wings is not what you should be researching now. You cannot overcome that technology. It will take time and scientific precipitation. When the basic industry reaches a certain level, mid-engine aircraft Only then will it appear. Our current scientific power can only support front-engine aircraft. We cannot even build rear-engine aircraft."
Liu Jinghong frowned and said, "But I think as long as the mobile hospital is powerful enough, we still have hope."
Li Zhen criticized seriously: "Why do you always place your hopes on others? Can you be more down-to-earth? According to conventional aircraft construction, the only ones that can go to the sky now are airships. In aeronautics, you are just a newcomer. I learned to crawl, but now I just want to run away. How is this possible? Scientists should have the spirit of fantasy, but if a sparrow eats beans, it has to be discussed with the bird, right?"
Liu Jinghong lowered his head and said: "Actually, my dream is a monoplane. But I must fulfill Lao Xu's last wish and use two wings to carry out the first space flight. So I imagined my fuselage as The idea is coupled with Lao Xu’s idea of two wings. I firmly believe that it can fly, it will definitely fly.”
Li Zhen saw that Liu Jinghong was so stubborn and was so stubborn that he couldn't say anything for a while.
After a long silence, he said: "There's no need to wait for the JIYI to break through the technology. If you want to try it, go ahead and try it now. Add the radial engine and start debugging it, and then prepare for a test flight."
Liu Jinghong was stunned: "So fast?"
Li Zhen laughed and said: "Yes. It's so fast. I want you to know what irreversible factors are."
