"It is necessary to pay attention to the application of new materials and increase the turbine temperature, which can significantly increase the thrust." "We can concentrate on tackling key problems, and all departments must fully cooperate with this project," said Ciric. ”

Jet engines, of course, are to concentrate on tackling key problems, and now, with the end of the war in Europe, the empire finally has a respite and can focus more energy on development, and this updated engine, of course, must be tinkered with as soon as possible.

Dr. Anselm was very happy to hear that all departments were required to cooperate with him, but then Ciric made an updated request: "Within two years, our new engine will achieve a thrust-to-weight ratio of more than 3 and a thrust of more than 20 kN, preferably around 30 kN." ”

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

Now, the thrust-to-weight ratio of the engines that have been put into service is only more than 1, and 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, and if you want to exceed 20 kN, or even 30, it will take the hard work of technicians.

But it is not impossible to achieve, the data proposed by Ciric is the data of the first generation of American engines J47 after the war, and this engine is improved from the German jet engine technology.

Ciric is not going to put unrealistic standards, but there is some pressure on the technicians, after all, when the magic weapon comes out again in two years, it will have to be a fairly mature aircraft.

What jets are mature? ME262 is definitely not counted, it should be an aircraft like F-86 and MiG-15, and Ciric needs to be stimulated by the war to reach this level in two years to continue to form an absolute crushing advantage.

"As for the lifespan, it is best to be able to reach 300 hours." This was the last requirement that Ciric made for the engine.

In later generations, the life of jet engines was often thousands of hours, and only the Soviet engine was at the level of 300 hours. Now set a small goal and reach 300 hours, otherwise, it will be too wasteful.

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

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

Ciric's words made Professor Messerschmitt nod his head uncontrollably, and there were really too many lessons learned in the development of ME262.

The biggest change in the swept wing, Cirek has already proposed in advance, they did not take a detour, but just a simple landing gear made them struggle.

In the era of propeller aircraft, the propeller of the aircraft was a terrible thing, and the aircraft had to raise its head and make its head higher so that the propeller would not touch the ground, so it was the landing gear at the last three points.

And the jet, there is no propeller, they are still designed according to the last three points, tossing for nearly a year, before it suddenly dawned on me that the first three points are more suitable!

"For example, the arrangement of the engines is the most important thing to discuss, and now we have engines on the wings, which I think is not perfect."

Jets are a completely new type of aircraft, how to arrange the structure, is a university question, and the current engine, like the propeller aircraft, is arranged on the wings, but it is not perfect.

Why?

To put it simply, once an engine stalls, it will lead to a huge yaw torque, and due to the high speed of the jet, there is very little time left for the pilot to react.

Professor Messerschmitt was aware of the problem, but he didn't have a good solution.

"Führer Ciric, what do you think is the best place to set it up?"

"Tail." "Two engines, arranged side by side at the tail, would have been the perfect solution," says Ciric. ”

The engine of a propeller aircraft is either the nose or the wing, and the engine of a jet aircraft, preferably in the tail.

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

And this arrangement, in history, has also gone through a long period of research and many developments and changes before it appeared. (The East China Hero will not be showy.) ）

The two, side by side in the tail, are almost on the axis of the aircraft, so that even if one of them misses fire, the other will not let the aircraft have much yaw, just move the operating stick.

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

Propeller aircraft don't have to worry about this problem, the air intake of the jet is dozens of times that of the piston machine, this problem must be taken into account, put on the wing, directly against the air, on the tail of the aircraft, that is directly against the fuselage, the air intake is blocked.

"On the sides of the fuselage, air intakes are set." "For us designers, the air intake is also a difficult point, and we want to tackle it as soon as possible," says Ciric. ”

With so many ideas, why didn't Ciric come up with them all at once? Because the amount of engineering is too large, everything is new, there are too many problems to overcome, and if you keep improving, it is impossible to reach the state of service now.

ME262, just solve the problem of whether there is or not, and next, will improve the performance.

Speaking of excitement, Ciric took out a drawing, sketched on it, and soon drew the structure of an airplane.

The nose air intake, swept wings, and front three-point landing gear, from the outside, are actually the appearance of the later MiG-15.

In his previous life, Shirek had a foundation in painting, he once drew the structure of a tank, and now he is also fluent in drawing airplanes.

When I used to go to school, I didn't want to listen to lectures, so I hid below and painted, and this kind of structural diagram is what he likes to copy the most.

"Of course, I only provide ideas, specific solutions, and the efforts of the whole team." Ciric said.

It is of course impossible to build an airplane from such a drawing, he only provides ideas.

Messerschmitt was pleasantly surprised, and they all said that Führer Ciric was a genius, and that was indeed the case!

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

The meeting has just begun, and there is still a lot more to be arranged, such as the development of ejection seats, the development of airborne radar, the shipborne modification of jet aircraft, and the launch of the more important jet bomber project.

However, the meeting was interrupted at this point, and an assistant hurried to report to Ciric that a delegation from the island nation had secretly arrived in Germany!
