Wang Yinan gave the team two days off, and before the results came out, everyone was driven back from the company by him to rest.

He put a sleeping bag in the basement, and as soon as he got into it, he fell asleep, in Wang Yinan's own words, "listening to the humming sound of the Gödel system, I felt that I slept very well."

The estimated end time of the calculation is a little more than six o'clock in the morning on the third day, and before five o'clock, Wang Yinan was dragged out of the sleeping bag, he went to the bathroom to wash his face in a daze, and came out to see, good guy, everyone is together. Chief Teacher Yang, Li Wenjing, and even Zhang Qi sat in front of the terminal early to occupy a good position, Zhang Qi asked Wang Yinan as soon as he saw his baby stereo, didn't it break.

Qian Zhonghua walked around the room as if he was facing a great enemy, and Wang Yinan walked over, "Why are you more nervous than me?"

"Go, you think everyone is as heartless as you",

"If you smash this performance, you won't be able to earn a penny at most, and Chief Yang will even be in trouble with 116 Institutes."

"Even your old man is in trouble, right?", Wang Yinan said with a smile,

"Put 10,000 hearts, I have a hunch, the result will be better than you can imagine"

Six o'clock was approaching, and the voices in the room slowly grew smaller and smaller, until at last only the humming of electricity and the occasional tapping on the keyboard remained.

After six o'clock, Wang Yinan felt that the current sound of Gödel's system seemed to become more active.

"Do you think this buzz has become faster", Wang Yinan asked in disbelief.

"Seems to be", several people around nodded their heads.

Qian Zhonghua didn't walk around the room either, he stood on tiptoe and stared at the monitor from behind, as if he was afraid of missing something.

At 6:34, three minutes before the expected time of Gödel's system, a beep suddenly sounded,

The sound of beeping and beeping seemed so harsh in the silence of the room.

Wang Yinan and Chief Master Yang glanced at each other, "It's better for you to come and see", Chief Master Yang finally coaxed, after all, this result is related to his reputation for half his life.

Wang Yinan walked over and sat in front of the terminal, at this time, the terminal began to print characters line by line, and the screen scrolled for several pages before stopping.

Wang Yinan said while turning the page forward,

"So many pages of content, it should be a good thing, the most afraid is to forget it for two days, and finally there will be a No Fault"

Thinking of that nightmarish experience, Li Wenjing shuddered and slapped Wang Yinan on the head, "Crow's mouth, do business!" “

Wang Yinan turned to the front, looked at it for a while, and was hesitating, but Chief Master Yang couldn't help it in the back,

"Why don't you speak, what's the situation, there won't be a problem?"

"No problem, I'll read it right away", Wang Yinan shook his head and read it out loud,

2. In the case of subsonic speed, the deflection angle of the canard wing is unreasonable during level flight, and reducing the upward deflection angle by 5 degrees can reduce the level flight resistance by 12%.

3. In the case of subsonic speed, the engine output is not coordinated with the canard wing deflection, and 10% of the lift is lost.

。。。

Wang Yinan read out two of them, then turned to the third page and said,

"Ge Kunpeng listed a total of 37 subsonic defects."

40. At transonic speed, if the afterburner ignition time of the engine is reduced by 0.2 seconds, the acceleration efficiency will be increased by 5%.

41. At transonic speed, if the canard and main wing surfaces maintain an angular difference of 7 degrees, the drag will be reduced by 3%

。。。

"There are also 9 transonic and 22 supersonic defects, I won't list them all"

"I rely on, I rely on it", Chief Master Yang was so excited that he didn't know what to do.

Wang Yinan pulled him over, "Don't be too happy too early, don't you let your supercalculations test one or two of them according to Ge Kunpeng's suggestion?" ”

Chief Master Yang finally came back to his senses, he picked up the phone and dialed the deputy chief engineer who stayed in Shudu 116,

"Lao Zhang, you immediately gather your subordinates to do a supercomputing simulation"

"What, you have other tasks?"

"Damn, don't worry about it, everyone immediately, immediately calculate this topic for me"

"Yes, immediately, immediately".

"You remember, at subsonic speed, reduce the deflection angle of the canard wing by 5 degrees, and then calculate the drag of the aircraft at 0.5.0.8 and 0.9 times the speed of sound."

"There must be results within an hour",

"Don't bargain with me, it's an order"

It's another long wait, and for this hour, the people of the 116 Institute are still very nervous, looking at what Ge Kunpeng said is the Tao, but whether this is the case or not, they don't know the bottom of their hearts.

The people in the company are very relaxed, and judging from Gödel's consistent performance, the probability of problems is very, very low.

"Ding Ding Ding", an hour passed, Chief Yang's phone rang on time, he picked up the phone, his voice was a little trembling.

"I'm Yang X, you say"

"0.5 times the speed of sound, 12% less drag, 0.8 times less 13%, 0.9 times less 15%?"

"Are you sure? Uh-huh, calculated three times, no problem, okay okay"

Chief Master Yang put down the phone, turned around, and loudly announced to everyone,

"Brother Kunpeng, it's soaring!"

There was a cheer in the room, and the siege lions of the 116 Institute and the employees of Rong and Rong have also formed a deep friendship in the past few months. Young people applaud and hug each other, and of course Li Wenjing and Sun Xiaozi are the two most popular hugging objects.

Wang Yinan and Chief Master Yang also hugged each other tightly, and then, Zhang Qi and Qian Zhonghua also surrounded them, and the four big men hugged each other and wept.

Chief Master Yang is undoubtedly the most excited one, and everyone here has a way out, except for him. If this performance fails, the first model chief engineer to take the blame and resign in office is not a good reputation.

A group of people ran to the courtyard, beer and champagne had already been prepared, as well as appetizers from the army canteen, not to mention the taste, it was enough.

A simple celebratory reception began spontaneously. Campfires, beer, and heavy metal rock.

In the cheerful crowd, Wang Yinan sneaked up to Chief Master Yang,

"Do you remember when I started to hesitate?"

"Yes, I still urged you for a long time"

"That's because I didn't read out Ge Kunpeng's first defective opinion, for fear of scaring you," Wang Yinan said.

"Listen, increase the canard wing area by 5%, reduce the vertical tail area according to the new shape designed as the rear, and follow the new shape of the rear design, which can avoid the front vortex from breaking in advance."

"At the same time, the engine compartment was reshaped to reduce drag by 10%"

"After combining the above measures, it is possible to achieve full-load supersonic cruise without afterburner"

"What?" Chief Master Yang was not calm immediately, he glanced left and right, everyone was celebrating wildly, and no one paid attention to them.

"Let's go, take me there"

The two walked to a terminal in the basement, Wang Yinan called up the output of Brother Kunpeng just now, and Chief Yang read the first article that Wang Yinan didn't read out just now, and then asked,

"That shape, did Brother Kunpeng give it out?"

"Well, in the attachment output later, the CAD drawings are directly given, I can't understand it", after speaking, Wang Yinan opened the attachment and gave the terminal to Chief Yang Division.

"This airfoil is a bit interesting, from the side, a bit of a supercritical wing feel, but not exactly"

"The shape of the vertical tail is very unique, a bit similar to the YF23 testing machine in the United States, so that the radar reflection area can be reduced a lot"

Chief Master Yang soon completely forgot about Wang Yinan.

Wang Yinan shook his head, left Chief Master Yang in the basement, walked up by himself, and started the carnival with everyone. Work is work, and when it's time to be happy, you should still be high, right?

When the party was about to end, Chief Master Yang climbed up from the basement step by step, and he found Wang Yinan and said,

"I have already had a brief discussion with Shudu on the phone, and Ge Kunpeng's plan is completely feasible."

"You've done you a lot of help this time."

Wang Yinan smiled and said, "It's nothing, it's nothing, it's just a gesture."

Chief Yang really wants to beat this girl, what does supersonic cruise mean, Wang Yinan doesn't understand, Chief Yang understands too much, at present, in the whole world, only one F25 in the United States can achieve supersonic cruise, that is, without afterburner, it can accelerate to more than 1.5 times the speed of sound and maintain long-term stable flight.

This means that fighters can reach the battlefield faster, fight longer (the difference in fuel consumption between afterburner and afterburner is more than five times), and get out of battle faster. ‘

With the design of radar stealth, it is the more God kills God and meets Buddha kills Buddha, the F25 of the United States often appears in the exercise, with one enemy ten, and then shoot down all the enemies, and they are all real gun exercises, there is no situation of releasing water.

Another stealth fighter in the United States, known as "Fat Lightning", uses a variety of advanced technologies, as well as the world's most advanced engine, but it still can't achieve supersonic cruise, so it can only be used as a supplement to F25 to form a combination of high-end and low-end machines.

Originally, when Chief Yang designed their fighter jet, it was necessary to achieve supersonic cruise for the F25. Helplessly, the domestic aero engine was not powerful, and the scheduled turbofan 51 was constantly postponed, so that Chief Yang had to replace the engine of Mao Xiong. In the case of the hairy bear's transmitter without afterburner, the thrust was very different from that of the turbofan 51, and Chief Yang had to give up the requirement of supersonic cruise in the first version of the model.

This has also become the biggest regret of the entire 116 Institute. Now that Ge Kunpeng actually said that supersonic cruise can be achieved under the existing conditions, then Chief Yang can not go crazy on the spot, which is already very self-contained.

"I'm going to go back immediately and adjust the aerodynamic shape and flight control system according to the new plan. Chief Teacher Yang asked.

"Yes, according to our experience, after about three iterations, the role of Ge Kunpeng is not much."

"This time, our 116 Institute is really going to release a big satellite", Chief Yang couldn't hold back the joy on his face.

Wang Yinan patted him on the shoulder, and rubbed his thumb and index finger in front of Chief Master Yang's eyes. "You know"

"Don't worry, I'll let them give you half of the funding for this year's flight control system now", Chief Yang was very happy.

"In addition, there will be a bonus for the successful test flight of the model, and this will also have yours."

"How much", Wang Yinan looked like a fan of money.

"Ask yourself", Chief Teacher Yang called after speaking.

"Cut, when I haven't seen money", Wang Yinan said disdainfully, and turned around to find Zhang Qi.
