Originally, young people are lively, plus they are all engaged in art, and they have never suppressed their feelings, as soon as the girl's voice fell, the other shouted more excitedly: "Don't say sleep for one night, even if I sleep for a lifetime, I am happy, you see, this chair is more comfortable than our sofa, and the ceiling light above, oh my God, it's really beautiful, alas...... You say it's with your boyfriend...... Is it going to be a romantic death. ”

"Of course I will, let me tell you, if one day a beautiful young man flies such a plane to marry me, I will marry without saying a word, without hesitation...... Then they flew with him to a desert island and gave birth to two...... No...... Four, yes, give birth to four children, he two, I two, think about it is happy. ”

Soon the third girl with a dreamy happy trill, faintly came from the cockpit, and then attracted the disdain of several boys outside the cabin, one of them even mocked: "Cut, there are still four more children, do you know about family planning?" But what you just said is really not wrong, this plane does not look very good, it is really comfortable to sit on, by the way, I used to see in magazines that foreign rich people and politicians want to plane, it seems to be this tune. ”

"Really?"

The girl who was originally very angry with this boy immediately forgot about giving birth to a child as soon as she heard the anecdotes of foreign countries, and asked curiously one by one.

The boy looked at the curious eyes of the girls, and his vanity immediately exploded, and he didn't want to say, "It's not." ”

It's just that as soon as he said this, there was a fried chestnut on the back of his head, and then Ju Tao's angry voice came: "What kind of, hurry up and work, don't eat today until you're busy." ”

As soon as the students saw that the teacher was mad, they hurriedly jumped out of the cockpit, while Ju Tao sat on the comfortable back chair like the uncle, looked at Erlang's legs, and from time to time took a sip of wolfberry water in the thermos cup, humming comfortably.

If there are no others, it's just that, the problem is that Zhuang Jianye and these people are still present, especially Ding Laixiang, the old professor has inherited the simple style of the fighting nation in his bones, and he can't get used to seeing Zhuang Jianye They made a transport plane into a special class, and now they have listened to a bunch of extravagant remarks of young drunken gold fans, and the old-fashioned Professor Ding only feels that his ears are already unbearable.

At this time, Ju Tao's obscene appearance with a satisfied face was looked at by the old professor again, and Ding Laixiang, who wanted to say a few words, immediately turned red with anger, and turned around and left without saying a word.

Zhuang Jianye and Lin Guanghua still had the care to pull down Ju Tao's goods to make the old professor angry, so they quickly turned around and chased out, just running for two workshops, and the two of them caught up with Ding Laixiang, who was running forward angrily.

As a result, Ding Laixiang was not doing well, but Zhuang Jianye and Lin Guanghua were already out of breath, and Ding Laixiang, who stopped, looked at the two young people in front of him who were not yet thirty, and were exhausted by him, the old man, and his unkind face was even more ugly: " Look at you, it's not even thirty, not even as good as an old man, the great revolutionary mentor once said that the body is the capital of the revolution, you don't care about the capital so much, and when you regret it in the future, you still build such a luxurious cockpit, it is estimated that before you fly into the sky, your body will not be able to hold it first. ”

"Hehe, then you always teach us how to strengthen our shortcomings in this area. Lin Guanghua saw that his mentor's anger seemed to have disappeared a lot, so he asked with a faceless smile.

Ding Laixiang glanced at his students: "Every morning, 100 sit-ups, 100 pull-ups, plus 5,000 meters of long-distance running." ”

Lin Guanghua, who was out of breath, almost fell down when he heard the words, he couldn't finish such a large amount of exercise, not to mention Lin Guanghua, even Zhuang Jianye, who "loves sports", couldn't play, so he decisively changed the topic: "Professor Ding, don't be like Xiaotao and them......"

"What do I have to know with a bunch of laymen? I'm angry with you. ”

Zhuang Jianye and Lin Guanghua were a little stunned when they heard this sentence, and then they glanced at each other, and just as they were about to speak, they saw Ding Laixiang raise his hand to stop the two and continued: "Am I still not clear about the contradiction between the people's growing material and cultural needs and backward social production? It is natural that the people yearn for more comfortable good things.

But the problem is, there are some things we have to do what we can, your improved Yun 5 is good in all aspects, many places have filled the domestic gap, but there are still some obvious that do not meet the requirements, not to mention, I will ask you, has the pressurized cabin technology passed?"

As soon as these words came out, Lin Guanghua's face immediately turned red, embarrassed, Zhuang Jianye's expression also changed several times, and he looked complicated with his old foundation being exposed, but fortunately, Zhuang Jianye's face was strong enough, and he returned to normal in a blink of an eye, and said with a smile: "Hehe, you don't say it, I still want to find a time to ask you for advice, there is really no precedent for our factory in this aspect of the pressurized cabin, so ......"

As a result, before he finished speaking, he was interrupted by Ding Laixiang raising his hand: "The reason why I came out was not for anything else, there were too many people inside, I couldn't talk too deeply, I had only seen this thing on imported civil aircraft, and they also disassembled it when they repaired it, and even took some samples for analysis, but unfortunately, we still can't figure out what materials they use and what process they apply." ”

Saying that, Ding Laixiang sighed, his wrinkled face was filled with helplessness that could not be concealed, looked at Zhuang Jianye and continued: "I know that you want to use the improved Yun 5 to attract other capable units and enterprises to tackle key problems with you in pressurized cabin technology, to be honest, we appreciate your courage and skill, but I have to tell you the bottom, the country has done research in this area for nearly ten years, but has not broken through so far, do you think that with the strength of your factory, you can provoke this beam?"

"Forehead ......"

Zhuang Jianye didn't know what to say when he heard this, not only because his mind was seen through by Professor Ding, but more importantly, his series of layouts were all shattered by Professor Ding's words.

The aircraft pressurized cabin is an important technology for aircraft comfort, and it is with this technology that the aircraft can fly at high altitude for a long time without worrying about the life of the personnel in the cabin due to low temperature, lack of oxygen, and pressure difference.

It is a very key basic technology for military and civil aircraft, whether it is the long-sea cruise and strategic delivery of military aircraft, or the personnel transportation and high-end cargo of civil aircraft, it is inseparable from aircraft pressurized cabin technology.

The most important target direction of Tengfei Plant's modified Y-5 is short-distance passenger and cargo transportation in high-altitude areas such as the Qinghai-Tibet Plateau and the border region.

In addition to improving engine performance, pressurized cabin technology is a hurdle that cannot be bypassed...... Outcome...... It really seems to be a hurdle......
