"We should 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 should fully cooperate in this project," Chirac said
Jet engines, of course, should focus on tackling key problems. Now, with the end of the European war, the empire finally has a breathing opportunity to focus more on development. Of course, this new engine should be developed as soon as possible.
Dr. ansellen was very happy to hear that all departments should cooperate with each other, but then hilrick put forward an updated request: "within two years, our new engine should achieve a thrust to weight ratio of more than 3, a thrust of more than 20 kn, preferably about 30 kn."
Thrust to weight ratio, the ratio of engine thrust to gravity, is the most important index of aircraft engines. For example, for later generations, for advanced engines, the thrust to weight ratio should reach 10.
Now, the thrust to weight ratio of the engine in service is only more than 1. It is difficult to achieve the thrust to weight ratio of 3.
At the same time, the thrust of the aircraft is only 8.3 kn. If you want to exceed 20 kn, or even 30 kn, it requires the hard work of technicians.
However, it is not impossible to achieve. These data proposed by Chirac are the data of the first generation engine J47 in the United States after the war, and this engine is improved from the jet engine technology of Germany.
Xierik will not put forward unrealistic standards, but it also needs to put some pressure on technicians. After all, when the magic weapon of watching the house is offered again two years later, it must be a very mature aircraft.
What jet is mature? Me262 certainly does not count. It should be an F-86 and MiG-15 aircraft. Under the stimulation of the war, xierik needs to reach this level in two years to continue to form an absolute rolling advantage.
"As for the service life, it is best to reach 300 hours." This is the last request for the engine.
In later generations, the service life of jet engines is often thousands of hours. Only the Soviet engine is 300 hours. Now set a small goal to reach 300 hours, otherwise it will be too wasteful.
"Yes, we should be able to meet this requirement if we concentrate our national efforts and the technicians obtained from Britain." Ansellen gritted his teeth and took it down.
Chirac nodded approvingly: "here's the problem of the engine. Let's go on to the problem of the aircraft. Our jet is a new type of aircraft, which is completely different from the propeller aircraft. We should boldly explore ideas in the layout of the aircraft."
Hirek's words made professor messeschmidt nod. There were too many lessons learned in the development of me262.
The biggest change is the swept wing, which was put forward by Chirac in advance. They didn't take detours, but it was just a simple landing gear, which made them take a lot of trouble.
In the era of propeller aircraft, the propeller of the aircraft is a terrible thing. The aircraft must look up and have a higher head before the propeller touches the ground. Therefore, it is the landing gear at the last three points.
The jet has no propeller. They still designed according to the latter three points. After tossing for nearly a year, they suddenly realized that the first three points are more suitable!
"For example, the engine layout needs to be discussed most. Now our engine is arranged on both wings. I think this is the most perfect."
Jet is a brand-new type of aircraft. How to arrange the structure is a university question. Today's engines, like propeller aircraft, are arranged on both wings, but they are not perfect.
Why?
In the simplest terms, once an engine stalls, it will lead to huge yaw torque. Because the jet is fast, it leaves little time for the pilot to react. Maybe it will destroy the aircraft and kill people.
Professor messeschmidt has been aware of this problem, but he has no good way.
"What do you think is the most suitable place for the layout, Sheikh?"
"Tail." "Two engines, arranged side by side at the tail, are the most perfect solution," said Shrek
The engine of a propeller plane is either the nose or the wing, while the engine of a jet is preferably 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 the thrust directly.
This arrangement, in history, has been studied for a long time and experienced many development changes（ The hero of East China doesn't show off.)
Two, side by side at the tail, are almost on the axis of the aircraft. In this way, even if one is on fire, the other will not make the aircraft yaw too much. Just move the operating lever.
"So, what about the intake air?" Dr. messeschmidt said.
Propeller aircraft don't have to worry about this problem. The air intake of jet aircraft is dozens of times that of piston aircraft. This problem must be considered. If it is placed on the wing, it is directly facing the air and at the tail of the aircraft. It is directly facing the fuselage, and the air intake is blocked.
"On both sides of the fuselage, air inlets are set." "For our designers, the inlet is also a difficult point, and we hope to grasp the key problems," hirek said
With so many ideas, why didn't Shrek come up with them all at once? Because the engineering quantity is too large, everything is new, and there are too many problems to be overcome. If we keep improving, it is impossible to reach the state of service now.
Me262 only solves the problem of yes and no, and then the performance will be improved.
Speaking of interest, Shrek took out the drawing and outlined it. Soon, he drew the structure of an aircraft.
Nose intake, swept wing, front three-point landing gear, from the appearance, it is actually the appearance of the later MiG-15.
Xierik in his previous life had the foundation of painting. He once painted the structure of tanks. Now he paints airplanes with the same fluency.
In the past, when he was at school, he didn't want to listen to the lecture. He just hid below and drew pictures. This kind of structural diagram is his favorite copy.
"Of course, I only provide ideas, specific plans, and the efforts of the whole team." Said Shrek.
Of course, it's impossible to rely on such a drawing to build an aircraft. He only provides ideas.
Messe Schmidt was greatly surprised. They all said that head of state Shrek was a genius. That's true!
There is a saying in later generations that a good plane must be a beautiful plane, and the plane drawn by hilrick now is a smooth and beautiful plane.
The meeting has just begun, and there are still many things to be arranged by hilrick, such as the development of ejection seats, the development of airborne radar, the shipborne modification of jets, and the launch of more important jet bomber projects.
However, the meeting was interrupted here, and an assistant hurried to report to Shrek that a visiting delegation from an island country had secretly arrived in Germany!
Please report us if you find any errors so we can fix it asap!
