Early the next morning, Jiang Tao was woken up by a knock on the door, got up and opened the door, this polite man standing outside the door, the only drawback was that he stared at Jiang Tao with a pair of red eyes, Jiang Tao was startled, thinking that I haven't offended people recently. Pen & Fun & Pavilion www.biquge.info thought about it for a long time, Jiang Tao didn't think of who he had offended, so he had to ask weakly: "That, who are you, I really don't think I've seen you." ”

The man outside the door sneered twice: "You only met me yesterday, and today you pretend not to know me, you really dare to act." ”

"What, you're Feng Jintang." Jiang Tao looked up and down, and found that it was difficult for him to associate this manly and beautiful man with the unkempt Feng Jintang yesterday.

"If it's fake, I'm Feng Jintang, the Feng Jintang who was scolded by you yesterday." Seeing Jiang Tao's surprised expression, Feng Jintang seemed to be very satisfied.

"Hah... Haha" Jiang Tao looked at Feng Jintang carefully again for a long time, and finally the eyebrows and eyes of the person in front of him were connected with the male drunkard from yesterday, and he laughed dryly, saying that he was very embarrassed.

"Okay, I didn't blame you, after you left yesterday, Nie Hengyu's kid also came to me, he said that now you have built a plane, and you want me to point you out, I was begged by him to have no choice, so I came to take a look." I have to say that Feng Jintang's words made the atmosphere even more embarrassing. Jiang Tao didn't know what to say, so he could only follow Feng Jintang's words and say, "Then please." ”

Jiang Tao took Feng Jintang to the front of the incoming plane, and the first sentence of Feng Jintang's mouth made Jiang Tao angry half to death, "Your plane is too backward, and you still use a three-wing architecture." Seeing that the aircraft he had worked so hard to develop was so disliked by Feng Jintang, Jiang Tao was also very dissatisfied and said, "That's all we have to do, why don't we see what tricks you have as an expert." ”

Feng Jintang didn't restrain his voice when he complained, and the surrounding group members all surrounded him with unkind faces, it is estimated that if it weren't for the fact that this person was brought by Jiang Tao, a beating would be considered light. It is estimated that if Feng Jintang can't come up with any good solutions, I'm afraid cynicism is inevitable.

"I can't talk about high tricks, but it's still better than you laymen." Feng Jintang drove the map cannon unscrupulously, regardless of the worse and worse faces of the people around him, "I said you don't have any brains, such a big engine is exposed, don't you know that this will increase wind resistance?" Can't you make a cover over him? ”

"But if you cover the engine, the heat dissipation of the engine becomes a big problem, and the engine will easily overheat." Hu Jun, who was holding back his anger, first fired at Feng Jintang.

"To say that you don't have brains is really brainless! Won't you hollow out the front side? Do you have to do it all? "Feng Jintang's poisonous tongue is full of skill.

"This ...... It seems like it really can. Hu Jun thought about it for a while and found that what Feng Jintang said really made some sense.

"So what do you think is the problem?" Jiang Tao found that Feng Jintang really had some goods in his stomach, so he was ashamed to ask.

"Questions, there are more problems, and it's been a long time." Feng Jintang turned out that Jiang Tao handed over a glass of water with a very good eye, giving Jiang Tao a teachable look.

"First of all, as far as I know, all countries are trying to develop all-metal aircraft, why are you still playing with wood, and ah, you don't put weapons on it, how do I know how your firepower is."

"This, in terms of firepower, in order to unify the model of the bullet, we intend to use a 12.7 mm machine gun as the weapon of the aircraft."

"Oh my God, what do you think, 12.7mm machine gun, do you know how heavy it is, are you going to have your plane with only one machine gun and your pilot to gamble on that poor hit rate, or are you going to carry only a little bit of ammunition?"

"But you also said that now all countries are developing all-metal aircraft, if you still use 7.7mm machine guns, can you cause damage to those all-metal aircraft, I don't want my aircraft to be eliminated after a long time." Jiang Tao retorted.

"What you say is not unreasonable, but I really suggest that if you really want to fight those all-metal aircraft, you better redesign a fighter, your current fighter has limited upgrade potential, it can be said that the design of the three-wing prevents the speed of this aircraft, and the future must be the world of monoplanes." Feng Jintang said categorically.

"But we now have a batch of combat aircraft that are urgently needed, so you should try to improve it." Jiang Tao, who has a system, knows that what he needs most is time, and he mainly has enough time to give full play to the ability of the system, and what kind of weapon is not a problem.

"If you insist on improving this aircraft, I can help, but you'd better not get your hopes up, this decision seems to me to be too stupid and a waste of my time." Feng Jintang is still the true color of that poisonous tongue.

"Then please." Jiang Tao clenched his fists hard, for fear that he couldn't help but punch this guy in the face. "Hu Jun, here you can cooperate with Mr. Feng. I had a few things to go first. Jiang Tao felt that if he endured it any longer, he would at least reduce his life expectancy. Just let Hu Jun and them bear it, don't you die and don't die poor, I have to say that Jiang Tao is really a little black-bellied.

"Mr. Feng, I don't know what you think about the engine, our engine is the key." Hu Jun gritted his teeth and asked Feng Jintang.

"Then you'll have to remove the engine and start it separately so I can take a good look, do you expect me to see anything?" Feng Jintang looked at Hu Jun with the same eyes as he looked at the mentally handicapped child.

Hu Jun wanted to beat Feng Jintang hard at this time, but he thought that what he said was reasonable, and it was worth suppressing his anger, dismantling the engine, and starting it for Feng Jintang to see. The "buzz" engine began to run. Feng Jintang listened and watched carefully on the side, not letting go of the slightest bit of information.

"You can stop." Feng Jintang said to Luneng, "You have a lot of engine problems, I really don't know which guy's idea." ”

"First, since you have thought of the structure of the star engine, why don't you add a few cylinders, which can greatly increase the power of the engine, why?"

"We also wanted to add multiple cylinders, but if we made it into a nine-cylinder, it would be heavier and the engine would be a little more complicated."

"These are not reasons, you must know that the power of the 7th cylinder is much less than that of the 9th cylinder, you don't have to care about the added weight, and even you can add a row of cylinders staggered, the only problem is the heat dissipation, forget it, when I didn't mention it, you can't even build nine cylinders, let alone 14 cylinders."

"Okay, I'll go back and study the 9th cylinder." couldn't stand being despised by Feng Jintang like this, Hu Jun and Luneng made up their minds to at least get the 9-cylinder engine out.

"By the way, why is the direction of rotation of your engine shaft the same as that of the propeller, don't you think that changing the direction of rotation of the engine shaft and the direction of rotation of the propeller to the opposite can improve the cooling efficiency of the engine, make the engine have better fuel economy performance, and improve stability, haha This engine must be designed by a layman, this guy is not even as good as a student of the aviation academy." This guy didn't go to aviation school. Feng Jintang, who was complaining about this, didn't notice that Hu Jun's face was completely blackened on the side.

"I've really been there, or you'll take me to class." Hu Jun pinched the bone joints in his hands and crackled.

"I mean, it's great that someone who has gone to an aviation school with no professional studies can design such an engine." Looking at Hu Jun's appearance of five big and three coarse, Feng Jintang stopped complaining rationally, it seems that he also understands the truth that heroes don't suffer losses in front of them.

"Can you still increase the power of the pistons with this engine, can you make them work faster?" Feng Jintang finally stopped his poisonous tongue.

"No, if you raise it again, the cylinder temperature will easily overheat."

"I said, can't you just hang yourself on a tree? Do you have to make cylinders out of steel? Haven't you tried anything else? Is there a material that is light and can withstand high temperatures? ”

"Yes." A man's voice came from behind.

"Venda, why are you here?" Luneng recognized this person, Wenda, who had officially developed the Zang rifle with him.

"I improved the barrel material of Jiang Tao's anti-aircraft machine gun, and I heard that Jiang Tao was working on an airplane with you, so I came over to take a look, by the way, what about Jiang Tao's people?" Wenda asked suspiciously.

"I couldn't stand being angry with this guy and ran away." Luneng whispered in Wenda's ear.

"Oh, it's kind of interesting to be able to make Jiang Tao angry."

"Okay, what kind of material are you talking about?"

"Aluminium oxide, this material meets the requirements you said, it is resistant to high temperatures, it is also light, and it also has the characteristics of high strength and wear resistance.

"Oh, that's just right." Hu Jun was very happy to hear the news

"But it's also very expensive, it takes a lot of electricity to produce, and there's no way to make the whole engine."

"That's a shame." Hu Jun said with some disappointment.

"Aren't you stupid to make the whole engine, we can use it to make key components? For example, cylinder heads and valves. Feng Jintang couldn't help but exert his poisonous tongue skills again.

"Ahh Hu Jun shouted, which startled everyone, among them, Feng Jintang was the most prosperous, he thought that Hu Jun couldn't help but beat himself, hey, why can't he control this mouth. Feng Jintang thought to himself.

"I see." Hu Jun's voice lowered again.

Feng Jintang patted his chest and let go of his heart, it seemed that he would not be beaten this time.

"That's all for the time, you can change it first." Feng Jintang quickly ended the conversation.

Another week has passed, Hu Jun and Luneng came up with a new 9-cylinder star engine, and the Xia brothers also made a fairing in time, and the plane with the fairing has become much more beautiful, although it is still the appearance of the three wings, but everyone knows that with a more powerful heart, the performance of this aircraft will be greatly improved.

Jiang Tao also got his aviation machine gun right, this time Jiang Tao racked his brains to find a way to reduce the weight of the machine gun, and finally controlled the weight, but in order to reduce the weight, Jiang Tao did not choose the water-cooled design, but chose the air-cooled design, in order to reduce the weight of coolant and water-cooled parts, but there are gains and losses, it is precisely because of the choice of air-cooled design that the barrel cooling of this machine gun has become a problem, Jiang Tao had to reduce the charge of the bullet and reduce the rate of fire to control the temperature of the machine gun.

Loaded two 12.7 mm machine guns on the plane, Jiang Tao naturally installed a shooting coordinator for the plane to prevent the bullet from hitting the propeller, and the time for another test flight came, calling Nie Hengyu as promised, when he boarded the plane, Jiang Tao noticed that Feng Jintang was abnormally not speaking, but his eyes showed a look of envy.

The humming sound of the engine sounded again, and this time the sound of the engine sounded more powerful and steady and regular to everyone than the last one.

The plane flew into the sky, Nie Hengyu really liked the feeling of soaring in the sky, and made several tactical moves in a row, he could feel that the power of the plane this time was even stronger than the last time.

"Try the machine gun" Jiang Tao shouted loudly below, but he couldn't, Nie Hengyu couldn't hear his shout at this time, but as an experienced fighter pilot, Nie Hengyu deeply knew the importance of firepower for a fighter.

Putting the imaginary target into the middle of the sight, Nie Hengyu pulled the trigger. "Da-da-da-da." Compared to the 7.7mm Lewis Aviation machine gun equipped with the Liao F1 fighter he once piloted, the range seems to be longer, and the bullet draws a slightly downward trajectory in the air, but compared to the original machine gun, this trajectory is much straighter.

Landing the plane on the ground, Nie Hengyu made no secret of his love for this plane, full of praise. Jiang Tao's group glanced at each other, and they were all excited.

"Jiang Tao, should we give our plane a name?" The surrounding team members hugged Jiang Tao and asked.

"If you want me to see it, it's called 31 type." I have to say that Hu Jun's ability to name is indeed poor to a level, and before Jiang Tao vetoed it, the people around him spoke out.

"What's this name?"

"Yes, no"

"If you want me to call it the Eagle, anyway, this is your first plane, so it's called that." Feng Jintang on the side changed his poisonous tongue and gave a good name.

"That's the name, that's it." Seeing that no one objected, Jiang Tao decided on the name "Young Eagle" for this aircraft.
