When leaving the mobile institute, Li Zhen found Jia Liping again, and specially allocated a scientific research fund to the mobile institute, and they specially developed this new type of engine by themselves.

Once this kind of engine is successful, it means that the mobile institute is completely on the right track. The implications are very far-reaching. It became the first institution to enter the stage of independent research and development from Li Zhen.

After coming out of the mobile institute, he entered the aviation research institute.

For the planes that can fly into the sky, Li really cares. Because now Shin-Kyushu is developing a project for air passenger transport.

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 is that hydrogen is too expensive, and the load of the airship is small.

It can only pull up to ten people at a time, it is only suitable for picking up VIPs, but not for the development of civil aviation.

And the pressure on the Aviation Research Institute is also very high, because the aircraft is 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 Institute.

When Li Zhen came to the Aviation Institute, everyone put down the workstations in their hands and got up to greet 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 type of aircraft structure that will be more suitable for flying. The finished product has been built, we have been dragged by a steam car, calculated the horsepower and compared it with the thrust of the star engine, which is more than enough to propel it to fly. ”

Li Zhen was a little surprised: "Oh? Made? Where is it? ”

Liu Jinghong hurriedly took Li Zhen into the compound in the aviation institute, this compound is only allowed to enter by high-level people, and inside is all the core secrets of the aviation institute.

In the courtyard, a behemoth was covered with canvas. If you look at the silhouette, it's what an airplane looks like.

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 big, bigger than the one we experimented with before.

In addition to this, the fuselage has undergone a lot of changes. The nose is sharper and the fuselage is more streamlined.

If you don't look at the wingspan and look at the fuselage alone, it looks and shapes very much like a horse-thorn. One of the bayonets, the front end is very sharp, and the further you go to the back, the larger it gets.

There are two seats in the middle, which can accommodate two people. And this load should be calculated in advance, so as not to cause imbalance and weightlessness.

The airplane has three wheels, one in the front and two in the rear.

The wingspan is larger and the structure is more stable.

To add strong stability, they added a lot of steel, sacrificing a part of the weight.

But the larger double-layer wingspan, as well as the slim fuselage, made up for the lost weight.

After the last failure, the Aviation Institute conducted a deep introspection. The wingspan cable, which was reoriented, was replaced by a thumb-thick steel tube.

Before it was the pull line. 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 of the control system.

They painted the wooden plane with silver paint throughout, and from a distance it looked like the metallic sheen of the fighter jets of that era. And the slender, streamlined fuselage looks even more psychedelic.

But Li Zhen is sure that this type of aircraft definitely did not appear in Zhang Zhi's era.

The fuselage of a slender fighter jet has a double wingspan.

It looks more sci-fi and more psychedelic in its senses.

Li Zhen looked at the flying machine carefully and said appreciatively: "I feel that it should be able to work." But there is a serious problem that must be solved. ”

Liu Jinghong asked: "What is the problem?" ”

Li Zhen pointed to the slender nose and said, "Where are the aircraft engines?" ”

Liu Jinghong said: "This is a breakthrough in our thinking. Our preliminary decision now is to install two star-engine setups on the wings. One on each side of the wings. Thrust is generated directly from the wingspan wings, neither front-engine, nor rear-engine, we are experimenting with mid-engines. ”

Li Zhen frowned: "Two engines? Do you know how dangerous this is? If the power of the two engines is not the same, 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 ......"

"Nothing. I know what you think, you want to swallow a fat man in one bite. But science should be down-to-earth, and we must not be ambitious. At present, the Kyushu Academy of Sciences does not have such sophisticated instruments, including mass-produced cars, and the power of each one is different. And how can you guarantee an aviation aircraft that requires more precision? ”

"Adding a power system to the wings is not something you should be working on right now. You can't overcome that technique, it takes time and scientific precipitation. When the basic industry reaches a certain level, the kind of mid-engine aircraft will appear. Our current scientific strength can only support the front engine. You can't even build a rear-engined aircraft. ”

Liu Jinghong frowned and said, "But I think that as long as the mobile courtyard is powerful enough, we still have hope." ”

Li Zhen criticized seriously: "Why do you always pin your hopes on others? Can you be more down-to-earth? According to the honest construction of conventional flying machines, only airships can go to the sky now. In aeronautics, you've just learned to climb, and now you want to run. How is this possible? Scientists should have a rhapsodic spirit, but when sparrows eat beans, they also have to discuss with their eyes, right? ”

Liu Jinghong lowered his head and said, "Actually, my dream is a monoplane aircraft. But I had to make up for Lao Xu's last wish and use wings for the first time in spaceflight. So I added my fuselage idea to Lao Xu's wings. I firmly believe that it can fly, and it will definitely fly. ”

Li Zhen saw that Liu Jinghong was so stubborn, and he actually got into the tip of the horns, and he couldn't say anything for a while.

After being silent for a long time, he said, "Don't wait for the mobile institute to break through the technology." If you want to try it, go ahead and try it now. Add the star engine to start commissioning, and then get ready for a test flight. ”

Liu Jinghong was stunned: "So fast? ”

Li Zhen laughed and said, "Yes." It's that fast, I want you to know, what is irreversible. ”
