"I can only find another opportunity later, and I have so many fruits in my own space, as well as all kinds of vegetables, I have to find a chance to take them out." Bangs thought to himself.

Bangs have been tried, and various crops in their own space can be multiplied, which should be affected by some strange power, unlike in 2020, when many crops had to buy seeds.

"Food security is the bottom line, and people will not panic until they are full." Bangs nodded.

"Hmm!" Sun Aiguo nodded, then chatted with Liu Hai for a while and left.

The next time Bang Hai was very busy, the manufacturing and testing of turboprop engines, the manufacture of the aircraft as a whole, and the installation of various internal systems.

Finally on December 20, the Y-9 aircraft began to officially lift the engine.

In the huge constant temperature workshop, the Yun-9 aircraft is a behemoth.

Yun-9 aircraft length: 37.54 meters.

Wingspan: 39.62 metres.

Height: 11.84 m.

The surface of the entire aircraft is coated with a protective layer, which is the yellow leather machine you see.

Looking at the behemoth in front of him, the eyes of the leaders present widened.

Liu Hai directed the hoisting of 4 engines on the spot, and if it was an emergency, the speed of the 4 engines would be faster, but because of the first hoisting, everything was stable.

The four engines were hoisted for most of the day, and after the hoisting was completed, they had to be energized for testing, and of course they could not be started in the aircraft manufacturing workshop.

Everything is ready after the power-up test, and then the start-up test is carried out the next day.

The leaders who came to watch the hoisting engine left after the engine hoisting was energized and tested.

The next morning, the leaders came again.

The assembled aircraft was towed out of the building and then directly onto the adjacent runway.

There are already people waiting on this side of the runway, although it is already a cold winter, but everyone is enthusiastic.

The first step is to charge externally, and after the first round of testing, refueling begins.

Of course, the amount of refueling for the first boot test is very, very small, and this is strictly limited.

It's not that you have to fill up the tank the first time, fuel is the biggest danger for an airplane.

Therefore, when each plane is refueled, the amount of refueling will be determined according to the range of the aircraft.

When it lands, it only meets a minimum safe oil level.

Bangs has strict rules for this kind of test, because these rules are all learned after countless lessons in 2020.

There is also a rescue vehicle for fire fighting and rescue next to it, as well as an ambulance from the hospital.

Liu Hai took the walkie-talkie and gave orders to various departments in an orderly manner, and then listened to the reports of various departments to make the next instructions.

After the aircraft is refueled, the cockpit crew reports the relevant data based on the feedback from the individual instruments.

At the command of Bangs, the first engine on the left side of the plane was started, and with the roar of the engine, the first engine was running normally.

Technicians on board the aircraft reported data on the first engine.

Then the second engine was started at the command of the bangs, and after the second one was started, the relevant data was obtained, and then the third and fourth engines were started.

The four engines were running at the same time, and Liu Hai listened carefully to the report of the technicians in the cabin.

After 10 minutes of operation, each of the four engines was shut down.

Because the engines are tested in advance, there is no need to inspect the engine.

Then do the second refueling!

After the second refueling, the engine is started in turn according to the previous procedure.

This time, the engines ran for half an hour, and during this half-hour, you had to keep an eye on the data from the four engines and test the aircraft's systems.

Aircraft air pressure system, aircraft control system, aircraft radio communication system, and other related various system testing.

After the second test, the technicians conducted a routine inspection of the aircraft.

After the inspection, Bang Hai decided to officially start the glide test.

Then we started refueling again, and after this refueling, we removed the wood that was blocking the front and back of the tires of the plane.

When the aircraft starts taxiing over the runway and further tests the operating system, wing tail and so on.

The ground test lasted for an hour, and the aircraft went back and forth on the runway, testing the various speeds of the aircraft and the impact of the engines on the entire aircraft system under various power conditions.

The noon meal was delivered, because the days are already short in winter.

In the afternoon, another hour of ground tests were conducted, after which flight tests began.

This kind of test speed is only now, and it is not so fast in the later aircraft design.

When the Yun-9 plane detached from the ground, the test pilots reported that everything was normal, and all the leaders on the tower of the test site applauded.

Sun Aiguo was even more excited, his face was flushed, even if he didn't drink, he felt like he was drunk, a big plane, this is a big plane.

When the plane circled in the air for twenty minutes and landed successfully, everyone involved in the test applauded excitedly.

This landing is followed by a check, and then a second go-around, which is a little longer because the aircraft is inspected as a whole.

So the plane had to be towed to the next hangar, and of course, all the fuel had to be drained before being towed into the hangar.

Although the Yun-9 plane only flew at a low altitude for 20 minutes, many people saw it.

After all, the sound of this kind of plane is very loud, and the Kyoto side is originally a plain, although the altitude is not very high, but you can still see it from a long distance.

This one is significantly larger than the one that was tested from the factory, and the body is still yellow.

"The motorcycle factory has built a new plane!"

"How do you know it's a new plane."

"How many years have I been in this area, I don't know that every plane is yellow at the beginning, our Y-8 aircraft is also yellow on its first flight, and the latter is painted in various colors, which is called factory testing."

"And this one is significantly larger than the Y-8 aircraft, with two more engines."

"Motorcycle factories are awesome."

"This still needs to be said, our factory is fortunate to be supporting the motorcycle factory to get better and better."

After the plane was towed to the hangar, it was the whole staff who took a photo with the plane.

"Senior sister?" When Liu Hai and the other leaders came down from the tower to take a photo with the plane, they saw an acquaintance.

Liu Hai knew that all the rescue and ambulance personnel were fully prepared for today's aircraft test, but he didn't expect his sister to participate in this test.

"Senior brother." The junior sister was also a little surprised when she looked at the bangs, her senior brother actually participated in this aircraft manufacturing?

"Liu Gong?" Several leaders who were with bangs saw bangs greeting people, so they asked.

"This is the daughter of Academician Zhu Haiyang, and she is also the technical backbone of our factory hospital." Sun Aiguo explained on the side.

"I've heard of it, I've heard of it!" The leaders of these departments nodded and looked at their junior sister twice, because it was the girl in front of them who performed cataract surgery on the superior leader, and it was successful.

"The technical backbone is good!"

"Your motorcycle factory is really full of talent!"

"Thanks to the support of the leaders." When Sun Aiguo heard the leader say this, he smiled and said modestly.

Then all the staff came to take pictures together, and the junior sister looked at the senior brother who was surrounded by many leaders, and felt a little incredible.

My brother has the ability in the motorcycle factory, and my sister knows a little bit about it, after all, it is not ordinary people who can get a car for themselves to drive, and his senior brother drove a Kyoto brand car early, and he is the first batch of people to drive this kind of car.

And the security of the place where his senior brother works is also very strict, but he didn't expect that his senior brother would be called Liu Gong by several such leaders.

"Senior brother is also here to participate in the test work of this aircraft?" After the photo was taken, there was a celebration feast, which was attended by those involved in this test and in the construction of the aircraft, and, of course, the leadership.

"Well, is it cold during the day today?" Bangs nodded and asked.

"It's just a little cold, saying that it's a special mission, I thought I was very busy, but I didn't expect to do anything." The younger sister is wearing a white vest.

The people who participated in the test at the site wore different clothes for each type of work.

This is also required by bangs, if everyone wears green clothes or factory work clothes, then it is not easy to distinguish.

Every step of the process of aircraft testing is very rigorous, eliminating the possibility of someone coming to help.

The person in charge of rescue wears an orange vest, the person in charge of refueling wears a red vest, and the ground maintenance wears a blue vest and so on.

Just like when refueling, all other people should stay away, and whoever has nothing to do with it should be close to whom, it is a violation of discipline.

During the same inspection and maintenance, no outsiders are allowed to enter the work range.

These are all accidents with countless accidents, and every rule accumulated by countless experiences is followed by an accident.

Of course, this process may take longer than everyone rushing up.

But the main thing about the plane is safety, reliability, and an extra 10 minutes delay on the ground is better than something in the air.

"This kind of test, you look at the excitement to prove that everything is going well, you have to be busy, it will be terrible." Liu Hai said with a smile.

At this time, Sun Aiguo came over: "Xiao Liu, let's talk over there." ”

"Xiao Zhu has worked hard." Sun Aiguo then said to his junior sister.

"It's not hard." The junior sister didn't expect Sun Aiguo to greet her.

"Who is this?" A few girls who were on a mission with their junior sister watched the big factory director go to a bunch of leaders with bangs on their shoulders, and hurriedly came over to ask their junior sister.

"This is my senior brother." The junior sister opened her mouth to answer.

"Why haven't I seen this senior brother?"

"Xiaoling, your title is wrong, usually your other senior brothers are what Senior Brother Li and Senior Brother Wang belong to."

"That's it, just call a senior brother this time?" A few of my sister's female colleagues whispered together.

Sun Aiguo was so happy, so he had a slight gaffe, and personally dragged his bangs to the leader's side.

This is a medium-sized transport aircraft, and there are few countries in the world that can make it.

Sun Aiguo dreamed of a large aircraft, and this has become, and today's successful first flight represents the countdown to the mass production of this aircraft.

Of course, Liu Hai knew that Sun Aiguo was very happy today, and the other leaders were also very happy.

However, Liu Hai doesn't drink, but these leaders drink and even Sun Aiguo is very happy to hold a wine glass today.

The current leaders will not say that they will find a place to eat and drink alone, and everyone will be together at the celebration banquet, and the people who participate in the test are very reliable.

"Liu Gong, I'll give you a drink, you drink it." A leader took a small shot glass and said to the bangs.

"Thank you, leader." Liu Hai is a little unaccustomed to this environment, but he also knows how significant the first flight of this medium-sized transport aircraft is to our country.

Immediately afterwards, several other leaders also raised their wine glasses, and Liu Hai drank the drink.

Everyone didn't say much about other things, but they were happy.

The leaders present have gone through very difficult years, so they are more touched by our current development.

These leaders talked about the hardships they had endured before, the sumptuous meals on the table in front of them, and the battles in the ice and snow.

Fortunately, everyone just drank a little too much, and it was a little bit of a feeling, not the kind of drunk nonsense.

"It's a mouthful of drink." After the celebration banquet ended, it was dark when he came out, and after Liu Hai was sent to the maintenance department by the people of the security department, Liu Hai felt that he was shaking a drink in his stomach when he walked.

After a busy day today, Liu Hai hurriedly went to the bathhouse to take a bath, and today he basically stood for a day, and when he didn't sit, he sat for a while when he participated in the celebration banquet in the evening.

Bangs likes to soak in the hot pool for a while after a busy day, which is too refreshing.

"I'm back, how was my mission today?" The younger sister returned to the hospital after attending the celebration banquet, and then went home from work.

"It's an easy day to do." The junior sister took off the cotton coat outside, then hung it up and said.

"The easier it is for us to do this kind of task, the better." Shi Niang is one of the leaders of the motorcycle hospital, and of course she knows what task she is going to carry out today.

To carry out this kind of special task, as long as the task is successful, then there will be a meritorious reward in the follow-up, of course, this kind of special task must be participated in by the backbone of a hospital, and ordinary people don't even think about it, and the level of confidentiality requirements is very high.

"I saw Senior Brother today." The junior sister spoke again.

"What department is your senior brother in?" Hearing this, Shi Niang asked curiously.

Zhu Haiyang and Shi Niang knew that Liu Hai was a genius, but the business scope of the motorcycle factory was too wide, so it was difficult to say which project Liu Hai was now.

"When I participated in the celebration banquet, several leaders called him Liu Gong and toasted him, and even a few people from the aircraft factory talked in private and said how Liu Gong was, how was Liu Gong?" The junior sister spoke again.

"Which leaders?" Hearing this, Shi Niang asked curiously.

"It's ......." The younger sister said the names of a few people.

After hearing this, the senior sister gasped: "Your senior brother has the ability, but it's not like this, right?" ”
