Lu Yuying was stunned.

He had just made up a lot of Du Yishan's reaction after hearing about the project funding, but he didn't include this one.

"Lao Du, this ...... This is a big project with a budget of 1 million, are you sure you don't want it casually? ”

For a moment, he even wondered if he had just said the wrong amount.

"It's not that you don't want to, but you want Chang Haonan to participate by name, this really can't be done. Our research group has also taken on another project, and he will soon go to Shengjing. Du Yishan said in a somewhat troubled tone:

"Otherwise, there is a doctor in our group, and he and I will go to your side to help?"

“……”

"No, no need......"

Lu Yuying, who heard this, was full of bitterness, and he didn't even know how he said goodbye to Du Yishan and hung up the phone.

In short, he only had six words in his heart.

"Obviously I came first......"

Although Lin Yichun, who had been sitting next to him, was the first to propose to find a way to bring Chang Haonan in, he was more open than Lu Yuying at this time.

After watching the latter hang up the phone, he got up and patted the other party on the shoulder:

"It doesn't matter, there is no chance this time and there will be a next time, besides, as long as the thinking does not slip, there are always more ways than difficulties, even if others are on the side of the 601 Institute, if we encounter any problems, we can still go to him for consultation, Huaxia Aviation Industry is a family after all."

"Alas......" Lu Yuying still felt a little pity: "If I can get his assistance, I am even confident that the prototype will be launched in about half a year." ”

"This ......"

Lin Yichun hesitated for a moment, but still said a word that I don't know if it counts as comfort:

"Actually, you don't have to feel too sorry, after all, even if we really get Chang Haonan over, the original ...... Originally, it was planned that he would mainly go to Project 10 to help. ”

“？？？”

Lu Yuying suddenly felt that the world was full of malice towards him.

……

The other side.

Yang Fengwan rushed back to Shengjing non-stop after the meeting, while Chang Haonan and Yao Mengna still had to stay at the school to go through some formalities, so they needed to stay at Jinghang University for an extra day.

On the morning of the third day, Du Yishan personally drove the two people to Nanyuan Airport in Beijing.

Although the airport in the 90s already had a security process, the whole process was still relatively sloppy, so it didn't take long for the two to take their luggage and walk into the cabin of a Tu-154M passenger plane under the guidance of the staff.

In addition to the more urgent business trips like theirs, you have to be quite rich to be able to afford to sit on a plane, and the capital to Shengjing is not a popular route, so the cabin is not full until the plane has begun to taxi.

After a short run, the Tu-154M flew into the sky at an angle that was very characteristic of the fighting nation.

Yao Mengna, who was sitting next to Chang Haonan, was a little restless, and her breathing range was much larger than usual, I don't know if it was because of excitement or nervousness.

"Senior brother, have you ever been on a plane before?"

Perhaps to divert her attention, Yao Mengna turned her head to Chang Haonan next to her and asked.

"Hmm...... I've never sat on this. Chang Haonan replied with a somewhat ambiguous answer.

Before he was reborn, flying was of course a common thing for him, but flying on the Tu-154M was indeed a rather novel experience.

"I've been studying aircraft design for seven years, but this is my first time flying."

Yao Mengna leaned over the porthole and looked at the buildings and roads below that were getting smaller as planes climbed:

"How long will it take us to get from the capital to Shengjing?"

"About an hour and a half......"

Chang Haonan has taken the most routes from Beijing to Shengjing and from Beijing to Rongcheng, and the plane in 20 years will not be much faster than it is now, so he gave an answer almost without thinking.

At this time, the plane had climbed to the cruising altitude, and due to the clouds, Yao Mengna could no longer see the situation on the ground.

"I thought we were going to take the train yesterday, so I looked for it and found that the train would take about 10 hours to get to Shengjing."

"Teacher Du and Mr. Yang will not be relieved." Chang Haonan shook his head: "There are many people on the train and the train station, any accident can happen, after all, the plane is safer and faster." ”

Trains in the '90s were synonymous with chaos, and if you had to sit on them, you had to do everything you could beforehand, such as sewing money onto the inside of your underwear, or carrying a quilt with you, sewing a bunch of small pockets inside the quilt, and putting valuables in it.

With the importance of Chang Haonan and Yao Mengna, it is naturally impossible to let the two of them take this risk.

"yes...... Faster. Yao Mengna stared blankly ahead, repeated in a somewhat stunned tone, and only looked at Chang Haonan next to him after a long time: "I don't know when we will be able to build a passenger plane like this in Huaxia." ”

Tu-154M is a 160-180 seat class trunk airliner, shortly before Chang Haonan's rebirth in 2023, Huaxia's first self-produced mainline airliner of the same class C919 will be officially put into commercial operation.

Of course, in 1980, the Y-10, which looked like it was in the same class as the Boeing 707, made its maiden flight.

But it's not enough to build an airplane that can fly into the sky.

In the field of aviation, the design and manufacture of civil airliners is actually more difficult than that of military aircraft.

Because airliners, especially mainline airliners, can be in the sky half of the day, there is a need for higher reliability, longer airframe life, higher structural strength, better fuel economy, and lower average maintenance hours per flight hour......

In short, large civil airliners are indeed the culmination of aviation industry technology, even if Chang Haonan has the experience and knowledge of later generations, and has the help of the system, there is really no way to give an accurate timetable.

Just because a person can eat five loaves of bread does not mean that he can eat only the fifth.

"Let's take it one step at a time."

Chang Haonan looked at Yao Mengna next to him:

"Isn't that what we're all striving for?"

Yao Mengna finally showed a smile:

"That's right."

After the plane landed at Shengjing Taoxian Airport, a 212 jeep with a white license plate directly took the two to the 601 Institute.

Yang Fenghat, who came back early, personally came to the door to greet him.

"We have already arranged the accommodation of the two comrades, a single dormitory, but a shared bathroom on one floor, and no kitchen."

"At noon, you should familiarize yourself with the location of the canteen, dormitory area and office area, and you can rest for a while in the afternoon."

"We happen to have a seminar on the progress of the project tomorrow night, if you are interested, you can come and attend."

Listening to Yang Fenghat's introduction along the way, Chang Haonan had only one thought in his heart:

J-8-3, I'm coming!
