1843: C1843 The Lift Fan

C1843 The Lift Fan

0You can't have both the fish and the bear paw. Of course, that was impossible, unless it was the super abnormal technology of the Y Country in the future. To be able to create an engine with a weight of 10, it was still not easy to deal with. Even so, the F-35 vertical landing fighter aircraft of the Y Country... It had been malfunctioning for so long. The cost of the project was also constantly being overspent.

In the current Bear Country, the engine cost a lot of fuel, and the weight ratio was not high. It was quite difficult to reach the standard of the future generations.

According to their design, the Jacques 141 fighter aircraft would be launched vertically. With a distance of 1500 kilometers, it was already much better than the masts. If it was a short-distance takeoff with a secondary fuel tank, it could reach 2100 kilometers. But now, even if it was just looking at the light F-16 fighter aircraft, the flight distance could easily be 3000 kilometers away, or even 4000 kilometers. Therefore, the journey of the Jacques 141 was quite short.

Now, Qin Guan actually said that the shortcomings of the voyage could be changed. It immediately made the people present excited. At this moment, ， everyone was in front of the Jacques -38 model, facing this model. They were all waiting for Qin Guan to explain.

How could he increase the maximum flight?

"Our vertical landing fighter aircraft uses the main engine behind and the layout of the Lift Engine in front. This method is very mature. The thrust layout is perfect and easy to control. However, this also causes the number of units in the entire power system to increase. Wasting space to increase fuel consumption, and the exhaust flame is too big... The problem of the burning deck cannot be solved "

The members of Yaklev Design Bureau were secretly impressed. Qin Guan was truly a genius. He was able to see the crux of the problem with a single glance and explained everything clearly.

That's right. This was the main problem of Jacques - 38, and even the Jacques - 141. Especially the Lift Engine in front, it was placed vertically. Facing the deck below, it spewed out a thousand degree tail flame. It was roasted directly at the deck. Nothing could withstand it!

When Han Country was faced with a problem, it was still earth magic that mounted the horse and laid a layer of fire resistant bricks on the ground. It was Chen Rui who had thought of this at that time.

Now, Chen Rui was also quietly listening to Qin Guan's analysis. He knew that his brother-in-law would definitely come up with a perfect solution.

Why didn't the Haiyao fighter aircraft have this problem of burning the deck? It was because the Haiyao didn't have a Lift Engine. They used an engine to direct the air in front of them.

"Then President Qin, how do you think this problem should be solved?" Dongdukov opened his eyes and looked at Qin Guan. He knew that Qin Guan would give him a perfect answer.

"The solution to this problem is actually very simple. Why do we have to put a special Lift Engine in front of us? Won't we solve it with a Lift Fan?" Qin Guan said.

The Lift Engine was a small jet engine placed vertically. The one that spurted out hot gases was now replaced by a Lift Fan. It was just like a big fan, blowing air down. If that was the case... It was the cold air that blew out, and the problem of burning the deck... It would be solved easily.

"President Qin, it's not that simple." Hearing what Qin Guan said, Dongdukov continued. Because he was in charge of this part. After all, Qin Guan was a layman, so it was too easy for him to think about the problem. "We have two Lift Engine placed in front of us, and the pushing force of each Lift Engine is 41 thousand cow. The pushing force of the two Lift Fan is 82 thousand cow. If we change it into a Lift Fan, then... What fan do we have that can provide such a strong pushing force? This idea is possible. In terms of engineering, it is unrealistic. What kind of system do we need to use to push this fan?"

There must be a power source for the fan, right?

Actually, using a single platform's Lift Engine was also possible. After all, its empty weight was only eleven tons, and the main thrust came from the rear. However, they had to go up two platforms to ensure that it was safe!

"As long as you use your brain, there will be a way." Qin Guan continued, "We can pick up a transmission shaft from the main engine at the back. This transmission shaft will be able to drive the fan in front of us. Isn't this enough power? Moreover, the biggest advantage of doing this was that it was easy to be trifled with. It was equivalent to the Outer Culvert of the Turbofan Engine. It only needed to consume a very small amount of fuel. We'll be able to achieve the greatest effect."

Currently, all the engines in the world were transitioning to the Turbofan Engine. Compared to the turbine, I added an Outer Culvert on the outside and used the axis of the engine to drive a few large fans. The wind blew backward, directly providing a pushing force. Like this. It increased a lot of additional thrust, and it could save fuel.

Now, he just needed to create a Lift Fan and receive the power from the back. That way, everything would be solved.

On the one hand, he was easy to deal with. He could get two Lift Engine. And both of them were like a turbine. That would require a lot of fuel. Now, it's just a big fan. If you're easy to deal with, it's absolutely necessary. On the other hand, the wind blowing down from the fan was cold wind. The problem of burning the deck could be solved.

What Qin Guan said was, of course, the idea of the F-35. The vertical landing model of the F-35 was referring to the Jacques 141. However, he had changed the Lift Engine in front of him into a Lift Fan. It perfectly avoided the flaws of the vertical landing aircraft.

Now that Qin Guan had finished speaking, he paused for a moment, giving the others time to think and react. If they could smoke here, lighting a cigarette and waiting quietly was enough to show off.

Qin Guan's words naturally gave them a huge shock. They had never thought about it this way before. That's right, if they did it this way... It would solve the problem and lead a transmission shaft over. They would transform the Lift Engine in front of them into a Lift Fan!

The Lift Fan would definitely be lighter than the Lift Engine. After all, it was only a part of the pressure of the engine. With the weight reduced, the extra weight could be added to the fuel. At the same time, it could also save fuel. One should know that... When the vertical landing aircraft consumes the most fuel, it is the time for the landing. It was not difficult to burn 20% and 30% of the fuel. Now, half of it could be saved. The fuel within the aircraft might be able to go from 1500% to 150%. What about 2,000?

Furthermore, the problem of burning the deck had been solved. This was the perfect fighter aircraft!

However, could it be that it was easy to achieve?

Eastern Shefu was the first to think of this question. He asked Qin Guan, "Do you know how much power this transmission axis needs to transmit?"
