Imperial Overlord

Speaking of technology, especially fighter jet technology, Tan Ke felt that he was in his own field. This was his profession and the topic he knew the most.

On this topic, he could easily talk to the head of state until tomorrow morning, and continue this kind of topic after breakfast, and it would not be difficult to talk about it for three days.

And he was happy to show his professionalism to the Fuhrer, to shock the Fuhrer and leave the impression of "I am very professional" to the man with the mustache in front of him.

If he can confuse the Fuhrer and let the Fuhrer take his own advice on the design and multiple-choice of fighter jets, then he can become the royal aircraft supplier of the Third Reich, and he will have no friends.

"Do you know the ME-109E fighter jet?" Li Le did not give Tan Ke much time to YY, and asked about the Messerschmitt fighter jet.

"Of course, the 109 is a classic fighter. It's exquisite and distinctive. It's a very good fighter." Tan Ke carefully chose his vocabulary and talked about competitors' products.

At this time, the ME-109E fighter jet was in its prime. Compared with the British Spitfire-1 fighter jet, this fighter jet still maintained a performance advantage.

Even if Tan Ke wants to slander, there is nothing to say. After all, the classic of 109, in the eyes of Defan, there is only one sentence - "It's not Hardman, you don't understand!"

However, Li Le interrupted Tan Ke's news broadcast evaluation, and directly talked about the familiar data of later generations: "The engine used in the ME-109E fighter jet is DB601A, and technically it uses an inverted V-shaped 12-cylinder water-cooled, take-off power. About 1050 horsepower, about 33L displacement, and about 600 kilograms in weight. Am I right?"

Tan Ke felt that he was messed up for a moment, and suddenly thought of a vague concept that often appeared in later generations—technocratic bureaucracy.

At this moment, he suddenly wanted to turn his head and shouted to the non-existent designers and apprentices behind him: "I'm X#$%, come and see! The Fuhrer really understands aviation! He really understands. !"

The original real head of state was actually a guy who was willing to use his professional knowledge to fool people in the industry.

The most classic case is that the Führer fooled the directors of IG Farben, and finally the head of IG Farben came to the conclusion that "the Führer is smarter than I thought".

He talked about politics and technology with the soldiers, about finance with the engineers, about military strategy with the chaebol nobles, and after a circle, he talked about the traditional Germanic spirit with a large group of fanatical believers...

If Zhao Benshan was a big fool who successfully abducted and sold it to Fan Wei, then the head of state is a super big fool, who can fool people all over the country and even the whole world into his pirate ship.

Obviously, most of Li Le or the keyboard warriors who talked about the mountains every day on the Internet in later generations inherited the eloquence of the head of state, and integrated a more erudite brain than the head of state.

So in terms of Kan Dashan's ability index, Li Le seems to be higher than the original one.

And Kurt Tank, who concentrates on design research every day, is not an opponent of this BOSS-level World War II fan at all.

"The intelligence department shows that the British's new plane is called Spitfire-1, and the engine used in this plane is Merlin 2." Before Tan Ke could express his admiration for the head of state, everyone was a professional, Li Le Come up with more exciting news.

These news obviously stimulated Tan Ke's curiosity, because he heard many data for the first time: "Merlin 2 engine adopts V-type 12-cylinder water-cooling method, the take-off power is about 1000 horsepower, the displacement is about 27L, and the weight is about 27L. Similar to DB, about 600kg.”

"We have a lot of advantages in terms of performance." Just hearing some data, Tan Ke was very convinced that the DB engine was much more advanced than the Merlin 2. Because he knew that DB used a lot of technology that seemed very advanced at the time.

"Yes, on the surface, it really is." Li Le nodded, and then continued to give his own evaluation: "DB is an inverted V-type machine, which makes the body of the Me109 smoother, but the maintainability may be Worse than a normal V-machine."

"My head of state, this is indeed a problem, but maintainability is only an indicator for evaluating an engine. If the performance is much higher, it is definitely worth paying some price." Tan Ke explained to Li Le with his professional knowledge.

Although he and Messerschmitt are competitors, standing on the righteousness of the national camp, it is necessary to seek justice for "domestic products".

"What you said does make sense, but what I want to warn you about is that maintenance and structural simplification are also important performances that must be considered." Li Le waved his hand in dissatisfaction. Of course he knew that at this stage, ME-109E The performance of the fighter is quite powerful.

But after a year, the gap on the engine was equalized by the British.

The following 1942, the German fighter's performance advantage ceased to exist.

As for the poor ME-262, Li Le didn't even have the slightest favor.

"If there are 1,000 fighter jets on the front line, each fighter can reduce the maintenance time by 6 minutes, which can accumulate 6,000 minutes, or 100 hours." Li Le made a simple calculation.

"The accumulation of 100 hours will make 5 fighter jets incapacitated in combat." He stretched out Wu Gen's finger and gestured: "I haven't done anything yet, so there are 5 fighter jets missing. ."

Tan Ke doesn't understand why he already owns 1,000 fighter jets, and he still cares about the five that can't be repaired. He also doesn't understand why Yuan Chief uses 6 minutes as an example.

Of course he didn't know that Li Le used 5 minutes as an easy-to-understand time unit in the past, but it was very troublesome to calculate later. Later, his memory improved and he used 6 minutes as an easy time unit...

"My head of state, a plane can't be repaired in 6 minutes." Tan Ke didn't know how to answer, so he had to remind him.

Li Le of course followed suit: "That means more losses! I will focus on this aspect in the future. You must pay attention when designing the aircraft!"

Tan Ke nodded quickly, eager to find a pen to record: "Yes, my head of state! I will definitely take the convenience of maintenance as an important reference aspect!"

Seeing that he agreed, Li Le, the fake head of state, began to show off his skills again, so dazzling that Tan Ke was embarrassed to say that he was a plane researcher.

"The designer of the ME-109E likes the shaft gun, or he thinks the shaft gun is easier to hit the target! In order to arrange the shaft gun, DB put the supercharger on the left side of the engine, and Merlin's supercharger is behind the engine, In contrast, the Merlin engine is more conducive to drag reduction."

"And I think that there is no need to stubbornly insist on the nose cannon. It is not worth giving up some performance indicators for it." Li Le brought up another topic to slander the ME-109E fighter.

On this point, Tan Ke did not defend his opponents, but he clapped his hands in favor of the Fuhrer's point of view: because the cannons of his FW-190 fighter jets were deployed on the wings.

So he took the opportunity to fall into the trap: "What you said is very correct. In fact, as long as it is properly adjusted, the hit rate of the wing weapon is not bad."

"That's not what I'm most worried about." Li Le waved his hand and continued: "Actually, I'm more worried about the new technology used on the DB engine."

DB adopted the most fashionable direct fuel injection technology at that time, so that the aircraft could fly without fear of negative G, while Merlin still adopted conservative carburetor technology, which may stall under high negative G conditions.

Similarly, DB used the world's most advanced continuously variable speed supercharging technology at that time, which could automatically adjust the supercharging ratio according to the height, while Merlin used a one-stage two-speed supercharger, which had poor adaptability to height.

Every time he mentioned these things, Li Le wanted to pat his desk very much, and smiled wryly at the person in front of him: "Look at it, look at the skills of the Germans, how high they are. ?"

The continuously variable supercharging may not have much contact with our lives. UU reading www.uukanshu.com will not do much evaluation for the time being. The in-cylinder direct injection technology has been one of the important technical branches of automobile engines until 2016. One, it can be seen how bad German technology was in 1936.

It's a pity... Defying the sky is on a crooked road. The quicker you are, the more you will be pitted against yourself and no one will come.

Although the DB engine using these new technologies has achieved a temporary performance lead over the British engine, it has completely lost room for subsequent improvement.

The main reason for blindly launching new technologies is that after the German ME-109 series fighters were improved to the G-type, their performance fell behind their old rivals, Spitfire.

Coupled with the pitiful 7.92mm caliber machine gun of the ME-109 series, this thing can only be regarded as unsatisfactory when fighting against the Allied bombers in the later period. It is better than nothing.

In the supercharging technology route, DB chose the route of high compression ratio and low supercharging ratio, the cylinder compression ratio is 7, while the supercharging ratio of the supercharger is lower; Merlin is just the opposite, the cylinder compression ratio is 6, The supercharger has a higher boost ratio.

In other words, DB assigns the task of supercharging more to the cylinder rather than the supercharger, which has the advantage of reducing the power consumed by the supercharger.

But there are two disadvantages: on the one hand, it will increase the cylinder stroke to increase the cross-sectional area of ​​the engine, and on the other hand, the greater harm is more frightening, and the detailed writing can be very long.

To explain it simply, it is this kind of design that makes the later improvement on the road of no return. The cost of wanting to improve and innovate is similar to redesigning an engine.

After talking for nearly an hour, when Tan Ke faced Li Le, he could only be described as confused.
