Chapter 895 The Standard of the MiG-15

"It is necessary to pay attention to the application of new materials and increase the temperature of the turbine, which can significantly increase the thrust." Cyric said: "We can concentrate our efforts on tackling key problems. All departments must cooperate with each other in this project."

Jet engines, of course, have to focus on tackling key problems. Now, with the end of the war in Europe, the empire finally has a chance to breathe and can focus more on development. Of course, this newer engine must be fiddled with as soon as possible.

Dr. Anselm was very happy to hear the full cooperation of all departments, but then, Cyric put forward an updated request: "Within two years, our new engine must achieve a thrust-to-weight ratio of more than 3. The thrust should exceed 20 kN, preferably around 30 kN.”

The thrust-to-weight ratio, the ratio of engine thrust to gravity, is the most important indicator of an aircraft engine, such as later generations, advanced engines, the thrust-to-weight ratio must reach 10.

Now, the thrust-to-weight ratio of the engines that have been in service only exceeds 1. It is difficult to achieve a thrust-to-weight ratio of 3.

At the same time, the thrust of the aircraft is only 8.3 kN. If it wants to exceed 20 kN, or even 30, it requires the hard work of technicians.

But it is not impossible. The data proposed by Cyric is the data of the first-generation American engine J47 after the war, and this engine is improved from the German jet engine technology.

Cyric will not put forward unrealistic standards, but he also needs to put some pressure on the technicians. After all, two years later, when the magic weapon of the house is offered again, it must be a fairly mature aircraft. Row.

What jet is mature? ME262 is definitely not counted. It should be an aircraft such as F-86 and MiG-15. Cyric needs to be stimulated by the war and take two years to reach this level and continue to form an absolute crush. Advantage.

"As for the lifespan, it's better to be able to reach 300 hours." This is Cyric's last request for the engine.

In later generations, the lifespan of jet engines is always thousands of hours. Only the Soviet Union's engine is at the level of 300 hours. Now set a small goal to reach 300 hours, otherwise, it will be too wasteful.

"Yes, if we concentrate our national strength and the technical personnel obtained from the UK, we should be able to achieve this requirement." Anselm took it with gritted teeth.

Cyric nodded approvingly: "Speaking of the engine problem, let's talk about the aircraft problem, our jet is a brand new type, completely different from the propeller aircraft, in the layout of the aircraft, we must boldly open up ideas.”

Cyric's words made Professor Messerschmitt nod incessantly. In the development of ME262, there were really too many lessons.

The biggest change of the swept wing, Cyric had already proposed in advance, they did not take a detour, but the simple landing gear made them go to a lot of trouble.

In the era of propeller planes, the propeller of the plane was a terrible thing. The plane had to look up and have a higher head so that the propeller would not touch the ground. Therefore, it was the landing gear at the rear three points.

As for the jet, there is no propeller. They still designed it according to the last three points.

"For example, the arrangement of the engine is what needs to be discussed the most. Now our engines are arranged on the wings, which I think is the most perfect."

Jet is a brand new type of aircraft. How to arrange the structure is a university question. The current engine, like the propeller plane, is arranged on the wings, but it is not perfect.

Why?

In the simplest terms, once an engine stalls, it will cause a huge yaw moment. Due to the fast speed of the jet, there is very little time for the pilot to react, and the plane may crash.

Professor Messerschmitt has realized this problem, but he has no good way.

"Führer Cyric, what do you think is the most suitable place to arrange it?"

"Tail." Cyric said: "Two engines, arranged side by side at the tail, is the most perfect solution."

The engine of a propeller plane is either the nose or the wing, while the engine of a jet is best at the tail.

Don't think about it, just look at the fighters of later generations. Almost all of them are arranged at the tail, which is directly the thrust.

And this arrangement, in history, also appeared after a long period of research and many times of development and changes. (The hero of East China will not show off.)

Two, side by side at the tail, almost on the axis of the aircraft, so that even if one fires, the other will not cause the aircraft to yaw too much, just move the joystick.

"So, what about the intake air?" said Dr. Messerschmitt.

Propeller planes don't have to worry about this problem. The air intake of jet planes is dozens of times that of piston planes. This problem must be taken into account. Put it on the wing, directly facing the air, and put it on the tail of the plane, which directly affects the It's the fuselage, and the air intake is blocked.

"On both sides of the fuselage, set up air intakes." Cyric said: "For our designers, the air intakes are also a difficult point, and we hope to tackle the problem quickly."

With so many ideas, why didn't Cyric come up with it all at once? Because the amount of engineering is too large, everything is new, and there are too many problems to be overcome. If we strive for perfection, it is impossible to reach the state of service now.

ME262, only to solve the problem, next, will improve the performance.

Speaking of excitement, Cyric took out a blueprint, sketched on it, and quickly drew the structure of an airplane.

Nose intake, swept wings, front three-point landing gear, from the appearance, it is actually the appearance of the later MiG-15.

In the previous life, Cyric had a foundation in painting. He once painted the structure of a tank, and now he is equally fluent in painting an airplane.

When I was in school, I didn't want to listen to lectures, so I just hid underneath and drew. This kind of structure diagram is what he likes to copy the most.

"Of course, I only provide ideas and specific plans, and it requires the efforts of the entire team." Cyric said.

It is of course impossible to rely on such a blueprint to build a plane, he only provides ideas.

Messerschmitt was greatly surprised, saying that Führer Cyric was a genius, and it really was!

There is a saying in later generations that a good plane must be a beautiful plane, and the plane that Cyric draws now is a smooth and beautiful plane.

The meeting has just begun, and Cyric has a lot to arrange, such as the development of ejection seats, the development of airborne radar, the carrier-based modification of jets, and the launch of the more important jet bomber project.

However, the meeting was interrupted here, and an assistant hurriedly came to report to Cyric that a visiting group from the island country had come to Germany in secret!
