Lin Youde was also watching the grappling in the air, and after seeing the eagle directly hovering and biting the Yankee with a large overload, he breathed a sigh of relief.

"Could it be that Dad, you were worried about us just now?" Xiaolu asked curiously.

Lin Youde glanced back at him and his daughter in the VIP room, and then said: "I'm a little worried, the shape of that thing is too much like a masterpiece machine in another time and space, and I'm worried that the Yankees have retained their strength in the previous simulation battle." ”

The JAS39 Gripen of another time and space is a well-deserved masterpiece machine, which is a single-engine light fighter designed to be frontal with the Su-27 heavy aircraft, of course, and the 27 Ji Gang is also wishful thinking on the part of the Swedes themselves, after all, they are heavy air superiority fighters, and you have a multi-purpose light aircraft to fight with it is still relatively reluctant.

But JAS39 has achieved the best in comprehensive performance, it is cheap, easy to maintain, eat less maintenance resources, and the air combat capability is actually acceptable after sacrificing some unimportant performance, especially in avionics, the electronic systems of the Soviet Union and Russia have always been more bulky than those of the West, so the larger fuselage of the 27 Ji has not brought such a huge improvement to the electronic system as the weight of the two aircraft.

Lin Youde was worried that the double-engine heavy version of the Gripen made by the Americans had inherited the air combat maneuverability of the original version, and now it seems that he is overly worried.

Lin Youde's Eagle has an amazing large overload maneuvering ability, and the F15 in another time and space has a reputation for having an actual overload maneuverability that exceeds the Air Force's design index, and the U.S. Air Force gives an index of 7. 3G maneuver overload, so when Israel came to buy the F15, the U.S. Air Force gave them flight guidance mentioned that maneuverability overload was limited to 7. 3G below, but when the Israelis went back to use it, they found that it was okay to pull up to 9G overload, but when 9G was overloaded, the driver's feeling was too slumped and could not be maintained for a long time.

And the Eagle style of this time and space has been improved, and the scientists and engineers under Lin Youde have conducted wind tunnel tests on the aerodynamic shapes of all famous aircraft in another time and space, plus there are already some master-level masters in the team, and when the third-generation aircraft of another time and space began to be designed, these masters almost knelt, and they were all born many years later in this time and space, and they all threw themselves under Lin Youde.

This group of people what F22F23 J-20 Su-37 aerodynamic shape has been carefully tested many times and seems to have been quite inspired, in the past ten years, the aerodynamic real yàn room has been engaged in a very big brain verification machine, fell to death Lin Youde full twenty elite test pilots, was scolded by Lin Youde before he began to engage in reliable design, although this Eagle is generally used F15 aerodynamic layout, but there are many differences in details, such as this F15 air intake is a variant of the DSI air intake, It doesn't have the complicated intake mechanism of the genuine F15.

The air intakes of normal third-generation aircraft have mechanical mechanisms to adjust the airflow into the interior, which not only increases the weight and maintenance of the aircraft, but also has a negative impact on the aerodynamic shape and radar reflection cross-section. The DSI intake not only reduces the weight of the aircraft, reduces the cross-sectional area, and makes the aerodynamic shape smoother, but it also increases the performance of the engine in disguise - although it is only a limited improvement, but it is better than nothing.

By the way, this DSI inlet looks simple, but in fact it has very high requirements for aerodynamics, fluid science and other disciplines, and the manufacturing of it also relies on high-precision production processes, and it also has quite high requirements for materials science. So in another time and space, there are only two countries that have DSI inlet technology: China and the United States, and even Lao Maozi and Europe have not done DSI.

But on Lin Youde's side, those big scientists first got an accurate view of the DSI inlet and knew what kind of thing it was, and after a lot of wind tunnel tests, they actually reversed the various fluid formulas needed by DSI, and then completed the aerodynamics and fluid theory behind it. To be honest, Lin Youde never thought that they would be able to complete this reverse extrapolation in ten years, and it was done in a very primitive state where the computer could provide very low computing resources.

It can only be said that some people are indeed born to be open-minded, and people are like this.

As for the manufacturing process, the current process accuracy does make the yield rate of the key part of the DSI inlet of the eagle very low - mainly the bulge itself, its shape must be very accurate, otherwise there may be problems, you must know that the speed of the eagle is very fast, such a high-speed air flow from the intake duct into the engine, once the bulge part of the DSI is a little poor, the operating efficiency of the engine fluctuates, and the heavy may directly fall the plane.

Although in the past ten years, Lin Youde has been working hard to develop and provide high-precision automated machine tools for his enterprises, but he has been trying to manufacture qualified components until now can only look at the sky - about two hundred substandard bulges will meet a barely usable one.

Fortunately, the alchemy materials used to make these key parts are relatively cheap, otherwise Lin Youde might have to order the eagle's air intake to be replaced with an ordinary air intake.

In fact, the No. 1 prototype and the No. 2 prototype that flew seven months ago did use ordinary air intakes, and it was the No. 3 prototype that came to fight with the Americans, and it was not long after it left the factory.

Lin Youde had already thought about it, and sold the eagle with the ordinary air intake to the allies, and the eagle he used was on the DSI air intake.

In addition, the air intake is not only the only improvement point of the Eagle in this time and space, it also has more than 100 modifications to design details, such as the rear line of its main wing is different from that of the F15, with a slight forward tilt, and so on.

It is precisely because of these differences in design details that Lin Youde's Eagle has achieved similar maneuverability to the F15 when the power is weaker than that of the F15.

When the new high-thrust engine is replaced, I'm afraid it will become even more terrifying.

In contrast, the Americans' big Gripen feels a little different from the real Gripen.

After being bitten for the first time, the simulation battle in the air continues, after all, the simulation battle is to get a number of jù, and the more times it is conducted, the more accurate it is.

The opposing pilot also seems to be an old bird, and has been trying hard to fight with the eagle, but he still keeps losing points.

"The enemy's plane is not completely crushed," Xiao Lu said after looking intently at the fighting situation for a long time, "They really hid their tricks a few days ago, and the F106 aircraft is now a bit higher than what we estimated in the simulated battle." But it didn't work, and overall the Eagle won. ”

"yes." Lin Youde nodded, "I feel that every time I restart the game, the Americans can hold it for a longer time, probably because they are gradually familiar with the performance characteristics of the eagle." ”

"So the conclusion is that there is a difference in the pilot's Su zhì, and the guide is not overwhelmed?"

"Well, although our test pilots have superb flying skills, they don't have much actual combat experience, they are professional test flight experts, and they are not so strong in war."

"Does the fact that the Americans use ordinary pilots to fly the aircraft means that they intend to mass-produce and install the F106 soon?"

"I'm afraid so, while mass production and installation, while developing fighters that can fight against the Eagle." Lin Youde pouted, "We really need to do some more tests before we can enter trial production, and if the Americans act fast, they can make their F106 combat effectiveness before we produce enough VF5 Hawk." ”

Although the Americans have been left behind little by little in scientific research, the arrogant and unreasonable industrial strength is there. Lin Youde, on his part, began to appreciate the limitations brought about by the lack of industrial capacity.

Germany is really inconvenient, the place is too small and the population is too small, which limits Lin Youde to increase the production capacity of his factory.

Judging from the current situation, when the rail elevator is built, Germany, which has gradually passed the demographic dividend brought by the post-war baby boom, may not have enough labor force to produce all kinds of things needed for space colonization.

If the rail elevator cannot be built in the last ten years when the demographic dividend has just begun to appear, the heavy responsibility of conquering the sea of stars in the future can only be handed over to Xinming.

"Daddy?" Xiaolu's voice interrupted Lin Youde's thoughts, "What's wrong with you, suddenly in a daze, the mock battle is over, we can go." ”

"Oh yes, just now your dad was lamenting the lack of industrial capacity. Now if we want to mass-produce a new aircraft, we have to worry about whether the production capacity can meet the demand, and when the orbital elevator is built in the future and we have to start expanding into space, I don't know if Germany's industrial capacity can support it. ”

"Hey, Dad, didn't you build the elevator to Southeast Asia just to rely on the power of Xinming to colonize the universe?"

Lin Youde couldn't help but shake his head: "How is it possible, Dad didn't think about it that much at that time, it was purely a choice made after considering the international political and military environment." ”

"That's right." Xiaolu nodded, "Actually, it doesn't matter, Dad, I think that as long as human beings are not tired of the starry sky, then even if there is no orbital elevator, human beings will launch guò rockets and turn space into our colony little by little." ”

"I can't be as optimistic as you, Xiaolu." Lin Youde shook his head lightly, "After all, in another time and space, I've seen enough of the human being standing still." So I still hope that your sister can do her best to get the cable material of the rail elevator ready. ”

"I think you might as well expect your new sister to spin." Xiaolu doesn't seem to be optimistic about Sophie's research prospects.

"New sister...... Lin Youde touched his chin, "Speaking of which, Isabella's belly is already very swollen now, it should be in the past two months......"

"Well, what does Daddy want that to be?"

"What do you mean by wishing that is? Hey, I just want to be a healthy child, nothing else, no need. ”
