Drawings of the Grasshopper aircraft appeared.

The Aviation Institute did not stop without any stops, and immediately began to build it. This time, they were full of confidence.

Although the dual-powered plane failed and crashed. But will the Grasshopper also fail?

No, absolutely not.

The Grasshopper may be small, but its stability will be very strong. It is estimated that even if the Grasshopper's engine stalls in the air, the plane will glide smoothly to the ground without crashing at all.

Especially after the last incident of broken wings. The Aviation Institute has a demonic pursuit of the strength of its wings.

The overall skeleton of the aircraft has been redesigned to incorporate the concept of keel, which is commonly used in shipbuilding, as well as mortise and tenon technology.

The entire grasshopper does not use a single screw, all of it is connected by mortise and tenon joints, and the skeleton of the keel is directly a double-layer defense means. The first layer is mortise and tenon joints, and the second layer is welding.

As for the firmness, the Aviation Institute has already fallen into the devil. It seems that after two crashes, everyone has a kind of obsessive-compulsive disorder.

Even if the plane falls apart in the sky, the wings are not allowed to break.

When the Grasshopper's wings were finished, they were tested using the strictest and most violent methods. A group of people jumped up and stepped on it. And no matter how you step on it, the wings just fan up and down, but they don't break. It is extremely flexible.

Of course, a part of the weight was also sacrificed.

But not much. These weights have little impact on the overall situation.

Because the Grasshopper is so small......

According to some students, this grasshopper can be driven by a practical two-stroke engine. The power of the radial engine is simply wasted on this.

But there were two failures in the front, and everyone was a little scared. The lion fights the rabbit, let's use all our strength.

Li Zhen passed by the aviation institute and glanced at it, and saw that the skeleton of the plane had appeared. People are filling the skeleton.

Looking at the model, Li Zhen didn't care too much, and he didn't have any curiosity.

This is the simplest model, and with the technology of the Aviation Institute, they can build it with their eyes closed. Not kidding, the Grasshopper is a small aircraft that is still biplane. Don't draw them and they'll put them together for you.

And now everyone is very serious about building it, and there is no possibility of it failing.

The principles are there, and the laws are there. All data is hard commodity. The only thing that can make it fail is that all kinds of people are not as good as the sky.

But Li Zhen felt that this kind of accident could not happen, because he found that the people in the aviation institute were a little perverted. The overall skeleton of this grasshopper is stronger than a car.

A wrist-thick steel pipe is the main beam of the Grasshopper, and the thick wooden steel bar, which is directly welded to the main beam with mortise and tenon technology, supports the wings. This skeleton alone weighs more than 100 kilograms.

Fortunately, the grasshopper is small in size, and no matter how heavy it is, it won't weigh much.

To Li Zhen's surprise, the wings of the Grasshopper were no longer hollow. The wings began to be filled with stuff.

It's foam.

The frame of the wing was filled with a layer of foam board, which was then covered with a layer of paper. Covered with another layer of silk. And then there's the canvas.

The use of foam will not have any effect on the weight, but it will make the wing more stable.

Li Zhen glanced at it twice and left, the Grasshopper will definitely succeed, this doesn't need to worry too much. However, I am still a little relieved that the Aviation Institute has come to its senses and has not continued to swell.

To be able to go back and develop an aircraft like the Grasshopper from scratch shows that they are ready to keep their feet on the ground.

Also, what Shin-Kyushu lacks now is flying experience. There is not only pilot flight experience, but also research and development experience.

The people in the Aviation Institute didn't know that Li Zhen had come, but they just buried their heads and continued to build the Grasshopper.

It's not technically difficult, but it's something you have to take seriously.

When the last layer of aluminum was covered with the fuselage, the Grasshopper was completed.

"Have you got the engine in the yard? Once you've got it, let it be shipped over, and then it'll be loaded. ”

Liu Jinghong commanded, and someone immediately ran to contact the people in the mobile hospital.

After a while, some people came over from the mobile courtyard, and Ma Jianbin also came over quite curiously. It also brought a star-shaped engine exclusive to the size of the Grasshopper.

Ma Jianbin looked the grasshopper up and down, frowned, and said, "Why are you so compact." ”

Liu Jinghong rolled his eyes, commanded the person to install the engine on the nose, and said: "This plane is short, but it is strong. ”

Ma Jianbin smiled and didn't say anything. But there was a trace of doubt in his eyes, is it so small, can it fly?

How big was the previous Swordfish, and how big is this grasshopper?

Let's see how big is the airship?

Liu Jinghong said: "Don't look at its small appearance, but in fact, its stability is beyond your imagination. 、”

Ma Jianbin laughed and said, "There won't be another crash, right?" I'm a little scared, I'm afraid that you will throw the pot at our mobile yard, saying that the engine is not good enough. ”

Liu Jinghong glanced at him: "I can tell you the truth, the safety of the Grasshopper is higher than that of the car." ”

"Hehe, how is that possible."

Ma Jianbin obviously didn't believe it. What are you kidding, the safety of an airplane can be higher than that of a car?

The plane is going to fly into the sky, and after flying into the sky, a small accident will die without a place to be buried. And the car, the car is running on the ground, and it is more controllable.

Liu Jinghong obviously knew that Ma Jianbin definitely didn't understand the reason.

To say that the safety of airplanes is higher than that of cars is to talk about the probability of accidents. It's not about the severity of the accident.

Of course, an accident in a car is not easy to cause death. Once the plane has an accident, it is a life and death.

But what Liu Jinghong is talking about is the stability of the grasshopper, which is too stable and too strong. Dapper. Even if the engine stalls in the air, it will not crash.

The only thing that caused the Grasshopper to crash was an explosion in the fuel tank, or a tornado.

However, with the shortness and strength of the Grasshopper and the power of the seven-cylinder engine, even if it encounters a tornado, it will probably be able to be thrilling.

When the engine was installed, the Grasshopper was finally born.

The people at the Aviation Institute painted it red, which looked more in line with this pocket-sized feeling. From a distance, the first impression that comes to mind is not airplanes, but candy.

Compared with the sci-fi streamlined body of the Swordfish. The Grasshopper is more of a toy.

Following.

Laoshan was excited again, and the Aviation Institute developed another kind of aircraft, called the Grasshopper, and today it is about to fly at the airport again.

Everyone was stunned:

"It's only been a few days, huh?"

"This efficiency is too high, right, a few days later, another new type of aircraft has appeared?"

"It's too sloppy, it's an airplane, how can it be enough for a few days? At first glance, it feels unreliable. ”

"The last crash is still vivid, and the Aviation Institute is too anxious."
