Kurt Tanck's words surprised Fang Lang, he heard Ante Polman introduce that Professor Tank was a genius aircraft designer, and he didn't feel anything about it.

It wasn't until they completed the project of the T-1 trainer at their own factory that they completely put themselves at ease.

However, it is really surprising to hear today that Germany had a jet fighter project named after him during the war.

With the urine nature of the Germans, if they want to name a country's project after an individual, it can only show that this person's ability has reached the position of one of the best in the industry.

Regarding Fang Lang's question, there was no need for Kurt Tank to answer it at all, and Ante Polman on the side had already spoken directly:

"The boss is right, the TA in the "TA-183" number is Tan Ke's surname. ”

Fang Lang, who received an accurate answer, was excited, grabbed Kurt Tank's arm and said:

"So what are you waiting for, show me the project that bears your name."

After speaking, he directly pulled Kurt Tank and walked to the other party's design room.

Kurt Tanke, who originally wanted to sell the project to Fang Lang, of course would not refuse, and followed closely behind the other party and walked quickly to his design room.

Ante Polman, who followed closely behind the two, smiled slightly, and hurriedly followed the footsteps of the two.

After the group entered Kurt Tanke's office in a hurry, Kurt Tanck was not polite and pulled out a rectangular suitcase directly from his desk.

Gently placed on the desk, under the gaze of Fang Lang and Ante Polman, it was carefully opened.

I saw that there were not many things inside, they were all drawings that were tied into a cylinder like a drawing scroll.

There must be more than a little bit of design drawings for an airplane, and Fang Lang is not in a hurry, waiting quietly on the side.

Kurt Tanck took out the drawings, looked at the markings on each drawing, and quickly pulled out one of the drawings, unslating the cable ties from the drawings as he turned to a display board behind his desk.

Seeing this, Ante Polman took two quick steps forward to help the other party unfold the drawing, and used a few small tools similar to magnets to glue the entire drawing to the display board.

As the drawings unfolded, the drawings of the appearance of the jet, named "TA-183", were displayed in front of Fang Lang.

At the first glance of the drawings, Fang Lang couldn't help frowning, this was not the same as the jet in his impression! If Fang Lang was to be asked to describe this aircraft in one word, Fang Lang could only think of one word, and that was ugly.

This is a single-engine jet, the air intake is located directly in front of the nose, the wingspan and length are not more than ten meters, and the diameter of the entire fuselage is very large, which is a bit contrary to the appearance of the slender jet fighter in Fang Lang's impression!

If Fang Lang had to find an animal to describe the plane, Fang Lang's first reaction would definitely not be a crow, but a pufferfish, yes, the puffer fish with a bulging head.

However, Fang Lang quickly thought of the world's first aircraft to fly into the sky entirely on turbojet engines, the HE178, which seemed to be very similar to this aircraft in terms of shape.

Perhaps this is the limitation of the single-engine turbojet engine on the body!

Fang Lang's reaction naturally couldn't escape the eyes of the other two, which made Kurt Tanke a little nervous, after all, if Fang Lang was satisfied with the law, this aircraft would obviously not be able to be established.

Therefore, Kurt Tank hurriedly took the initiative to ask:

"Boss, I don't know if you are dissatisfied with my plane."

When Fang Lang heard this, he knew that the two of them had seen his reaction, so he hurriedly waved his hand and stepped forward to a place closer to the drawing. This time he was no longer looking at the front of the plane, but from above.

If Fang Lang had just come to this world, he might not be able to see any difference from this top view, but Fang Lang, who had experienced the Pacific War and carefully studied the piloting of an airplane, quickly discovered something unusual.

Somewhat incredulously, he went straight to the front of the drawing, pointed to the wings of the plane in the top view, and said in a slightly trembling voice:

"Is this a swept wing?"

After Kurt Tank heard Fang Lang's words, he also looked at Fang Lang with a surprised face, and asked with a little doubt:

"Boss heard about Swept Wings?"

"Of course, how could I not have seen a swept wing! Wait, I'll take another look. ”

Fang Lang can now be sure that Kurt Tank is definitely a genius, and after discovering this swept wing, Fang Lang immediately put his original first impression behind him and began to carefully study all the details of this aircraft.

The more he looked at Fang Lang, the more surprised he became, because as he looked closely, Fang Lang found that many of the designs of this aircraft, which made him feel very ugly at first impression, were very advanced.

In addition to the swept wing that shocked Fang Lang, there was also his huge vertical tail sweep angle of 60 degrees, and these aerodynamic layouts all said a thing, and that was that this was a very fast jet fighter.

Looking at it, Fang Lang gradually noticed that something was wrong, and then he almost jumped up directly and slapped his thigh.

"Isn't this a MiG-15 after the weight loss?

Wait, when did the MiG-15 come out, damn, it doesn't matter, it definitely hasn't come out yet.

That said, this could be the MiG-15 thing! ”

Fang Lang's sudden performance directly made Kurt Tank and Ante Polman beside him stunned in place, because Fang Lang spoke Chinese, and the two did not understand, but from Fang Lang's movements, the two could see that Fang Lang was excited.

And, obviously, very satisfied, the excitement of being pleasantly surprised.

Kurt Tank, whose previous question had not yet been answered, couldn't help but speak again:

"Boss, I wonder where you've seen this swept wing design? This is a new layout that we discovered after many experiments in the wind tunnel! ”

Fang Lang, who had already had some aftertaste, looked at Kurt Tank with bright eyes, and after hearing his words, he said directly:

"Oh! Why did you choose this layout? ”

This kind of question is of course the simplest question for Kurt Tanck, who personally designed this swept wing, and replied casually without hesitation:

"After our wind tunnel experiments, straight-wing aircraft are strongly impacted by the compression effect at near-sonic speeds, producing violent shock waves, while swept wings delay the generation of shock waves, and the intensity of the shock waves generated at supersonic speeds is much smaller than that of straight-wing aircraft, giving the aircraft better handling at high speeds.

And our TA-183 project, as a jet fighter, has a top speed of close to Mach 0.8, and only the use of this swept wing layout can give our aircraft better maneuverability in battle.

Where did you see this layout? Could it be that who else is discovering this new layout at the same time? ”

After Kurt Tanck's explanation, Fang Lang has made it clear that the Kurt Tanck in front of him must be the inventor of the swept wing. And the MiG-15 was obviously designed and manufactured from the inspiration found in this TA-183.

You must know that the MiG-15 was later introduced by his hometown, that is, the J-2 that we saw in the museum in later generations, which is why Fang Lang felt more familiar the more he looked at it.

Hearing Kurt Tanck repeatedly ask where he had seen this kind of layout, Fang Lang didn't know how to answer this question for a while, he couldn't tell him that he had seen it in the later life!

Seeing Ante Polman on the side, Fang Lang quickly thought of an answer, and hurriedly said:

"Hey! I went to Germany to look for Polman because I was told that someone in Germany had come up with a completely new aircraft layout called a variable sweep wing.

Later, under Polman's introduction, I learned what exactly swept wings and variable swept wings mean.

So, seeing this swept wing layout of yours today is recognizable to me at a glance. ”

This answer made Ante Polman, who was on the side, blush slightly, after all, he used this variable sweep wing technology to go to Bristol, England to deceive, so that Fang Lang came to the door.

Hearing Fang Lang talk about this experience again, he couldn't help but blush.

Fortunately, Fang Lang didn't say anything about his swagger and deception.

Hearing this, Kurt Tanck looked at Ante Polman and asked with some confusion:

"Variable swept wings? Which Hans Hornon came up with the ME P.1101 project? ”

As a well-known German aircraft designer, of course, he must also have a certain understanding of the products of other companies, so when Fang Lang said the first time the variable sweep wing appeared, he thought of the first model with this technology.

Hearing Kurt Tank's question, Ante Polman didn't say much, just nodded lightly and confirmed the other party's question.

After receiving an affirmative answer, Kurt Tank also nodded seriously and said:

"To be honest, Hans Hornon's idea is very constructive, but the use of this variable sweep wing will increase the weight of the wing, which is somewhat more than worth the cost."

It is normal for everyone to have different points of view, and Fang Lang and Ante Polman do not want to continue to dwell on this topic.

Fang Lang was the first to raise his own question:

"Professor Tanke, why did you design such a short fuselage?

It seems, the whole plane seems to be ..... Well! How so? .... Something weird. ”

Hearing this, Kurt Tanck was not angry, but said with a smile on his face:

"In fact, the reason for this design is also for the sake of stronger maneuverability, after all, a short fuselage means a smaller turning radius and more flexible maneuverability."

These words made Fang Lang react immediately, it seems that this is designed for dog fighting! Hurriedly opened his mouth to confirm:

"Then I don't know what the main weapon of this plane is....?"

Kurt Tank didn't hide anything, and said directly to Fang Lang:

"At the time of design, we had two weapons schemes: four 30mm MK108 cannons, plus a five-hundred-kilogram bomb. The second is four 20-mm or two 30-mm cannons, plus carrying 500-kilogram bombs. ”

As soon as he heard this weapon configuration, Fang Lang understood why he felt that the shape of this aircraft was so different from the shape of the aircraft in his impression.

This is because the common fighters in later generations are all advanced fighters that launch missiles at high altitude and high speed and outside the line of sight. And the current jet fighter still has not gotten rid of the combat mode of using cannons for close-range dogfights in the air.

To be able to engage in close dog fights, you need to have excellent maneuverability, and the short fuselage of this aircraft is clearly motivated by this.
