Chapter 41 Aircraft Engines (I)

The task of improving the barrel steel was handed over to Wenda, and Jiang Tao himself had to organize a team to tackle key aircraft, but Jiang Tao currently had the only team members in his mind to let him and Luneng, processing experts, and the rest of the candidates all depended on Chen Haisheng's recommendation. Pen, fun, pavilion www. biquge。 info

Thinking of going to Chen Haisheng for help, Jiang Tao had no choice but to pretend to be a dog's leg, poured a cup of tea for Chen Haisheng, handed the tea, Jiang Tao opened his mouth in an extremely respectful tone: "Director Chen, you see that I am not familiar with this factory, and I will have to rely on you a lot in the future." ”

"You kid don't come to this set less, I've seen a lot, I have nothing to do, I'm either a traitor or a thief, say, what do you kid want to ask me for?" Chen Haisheng drooped his eyelids and took the tea.

"Didn't I promise Captain Nie Hengyu to get the plane out for him within a month? But designing and building an airplane is a big project, and I don't want to ask you for talent. ”

"You really plan to get the plane out in 1 month, do you know how long it took them to learn how to repair the plane?" Chen Haisheng couldn't believe it. The spittle stars were about to splash on Jiang Tao's face

"Hey, do you have to give it a try? You also know that our plane was either brought into the Guannai or destroyed by ourselves in Mukden City, so we can't watch this little Japan show off its might on our heads. ”

"Didn't you kid toss that anti-aircraft machine gun, what are you afraid of, besides, even if we get a plane, we don't have gasoline to let him go to heaven."

"Hey, I didn't ask you to be in charge of the development of that coal-to-oil technology."

"I said you kid, you have a plan, okay, tell me, what kind of person do you want."

"This. I want a math master, a few people who study engines, and by the way, a few carpenters who are good at their craft. "Someone will ask Jiang Tao Didn't a few technicians come out of the airport at that time? Why look for them? In fact, Jiang Tao went to them at the beginning, but after chatting, he realized that this group of people was called to be in charge of the runway at all, and the maintenance of the aircraft depended on those technicians invited from abroad.

"You kid, when I'm here to open the school, there are no math masters, there are no engines, only those who can repair truck engines, and the carpenters will give you the three best." Chen Haisheng

"Then thank you, Mr. Chen." Jiang Tao also asked for a sky-high price and landed the idea of repaying the money, originally just wanted a few carpenters to help, and it was already a surprise to be able to get a few who could repair truck engines, maybe he could really develop an airplane. ”

Chen Haisheng introduced people to Jiang Tao, and went to work on the things in the factory by himself. Jiang Tao also called Luneng over, and when they got to know each other, the three carpenters were all surnamed Xia and three brothers, all of whom were ancestral crafts. As for the engine repairer, he was called Hu Jun, who used to be a car soldier in the army, but when he was injured, he became an auto mechanic. A small group of people got to know each other and found that they could look at each other as well.

"Ahem, the big guys know what I'm doing when I got you all together, yes, we're just going to try to get the plane out in a month. Don't worry, it's my business if you can't figure it out, you just have to do your best, Luneng knows me best, and he can prove that I am definitely not from above. Everyone looked at Luneng, and Luneng nodded without hesitation, and Tao's words dispelled these people's worries and concerns.

"Then let's start with the engine first, Hu Jun, that's what you're doing, do you have any suggestions?" Jiang Tao thought that the three stinkers would set up Zhuge Liang, and the two of them could be regarded as half experts.

"Hey, you know, our engines run on the ground, and I really don't know what it looks like in the sky." It's a pity that Hu Jun's answer really disappointed Jiang Tao. I can't count on anyone to come, so I can only bite the bullet myself. Fortunately, Jiang Tao has the impression that the old-fashioned piston engine seems to be a kind of star engine that is particularly famous. This star-shaped engine is characterized by the fact that the cylinders are arranged around the crankshaft and are shaped like a star, hence the name.

"You said that if we want to make the plane fly into the sky, we have to make the engine small and powerful, right, so why don't we add a few more cylinders?" Jiang Tao began to guide the group members.

"I'm afraid this method won't work, if the cylinder increases, then the weight of the engine will also increase greatly, so the weight of the aircraft will still be very heavy, not to mention that it is also a trouble to install a larger engine into the aircraft." Hu Jun directly raised objections.

"Is there a way to increase the cylinders so that the weight of the engine does not increase too much?"

"Add cylinders, cylinders" Hu Jun thought, and suddenly his eyes lit up, "We can combine two in-line engines at a certain angle and share a crankshaft." This saves a crankshaft, and although the length is slightly increased, the width is increased by about half, and the height is basically the same, I estimate that with a weight increase of about 50%, you can get a lot of weight savings that are twice the power of an in-line engine. ”

"Can we have more cylinders on one crankshaft?" Jiang Tao asked downward.

"No, a crankshaft with two cylinders is already very reluctant, if there are more, you have to change the transmission structure, this is a big project, even if it is successful, then his process will be very complicated, and it will be very troublesome to maintain."

"That's right." Jiang Tao also became a little entangled, in fact, he forgot that in addition to the star-shaped engine, there was also a V-shaped engine that was also famous for the piston engine in World War II, which was the method that Hu Jun thought of, combining the two in-line engines at 60 degrees. However, this design also has its disadvantages, because multiple cylinders have to output power along the crankshaft at the same time, and the strength of the crankshaft is limited, so the engine can only arrange 6 cylinders per row, and because the cylinders in the back are difficult to rely on air heat dissipation, it is necessary to add a complex water cooling system. The common V-shaped water-cooled engine is basically a 12-cylinder design, so its maximum power is also limited, and the room for further power is limited. The compact layout reduces drag, but it also complicates maintenance, and if hit in combat, the impact is often larger. The cooling system of a water-cooled engine is also the "Achilles' heel", and once a bullet is damaged, the cooling water may be lost, and the engine may quickly overheat.

So this thing may be providential, Jiang Tao didn't remember the V-shaped engine, so he luckily avoided wasting time on the V-shaped engine that was not too suitable for him.
