The engine had undergone a series of adjustments prior to the test, which was not equipped with a large blade.

The paddle was installed for testing in a separate place, and the engine was fixed on the test bench.

It is connected to various lines and pipelines, because there are many items to be tested during the test, including the overall power, suction and exhaust, temperature, and tubing pressure.

All staff members follow their own operating manuals, step by step.

Liu Hai also gave orders step by step according to the operation manual, and then received a reply step by step.

The leaders and bangs stood behind a thick bulletproof glass, and there was a layer of stainless steel wire mesh in front of the bulletproof glass.

Once everything is ready, the ignition will officially begin.

Of course, the ground test is to start the ignition with an external ground power supply.

After start-up, each operator reports his or her current data.

Bang Hai summarizes the overall data, and of course, the operator also knows whether there is any abnormality in the data he is currently reporting.

When the bangs are crossed, this test bench is a more advanced intelligent system.

Commanders can see at a glance which data anomalies are based on the data on the screen.

Of course, the intelligent system can only be used as an auxiliary system, because the data of the intelligent system is collected through various sensors, and once the sensor has a problem, then the data cannot reflect whether it is correct or not.

After the first ignition was successfully started, the leaders present clapped their hands one after another.

But no one said anything too much, and the bangs had already gone to start checking.

This kind of inspection is to take a flashlight for routine inspection, and at this time the engine does not have a shell, you can see the various pipelines on the engine, and you can also see the various parts inside.

After a detailed inspection, I looked at the various data of the engine operation just now, and then started it a second time.

In fact, the engine test is far more cumbersome than the bangs, because the bangs copy a mature design.

An immature engine can take years to refine and improve.

Some engines are even scrapped after a few years, because you don't realize until the end that this is a major design and structural flaw, and any subsequent changes cannot be completely changed.

That is to say, when it comes to designing and manufacturing everything, there are almost no mistakes, and there is no room for more optimization.

It was launched three times in one day, but the results of the three tests satisfied everyone.

"Liu Gong is worthy of Liu Gong, we will soon have our own medium-sized transport aircraft." When they ate together in the cafeteria in the evening, the leaders of the aviation department praised Liu Hai, and now these leaders also want to call Liu Hai Liu Gong, not Xiao Liu or something.

"Thank you for the leader's praise, and thank you for the strong support of the leader, if it weren't for the full support of the leader, I wouldn't have been able to come up so quickly." What Liu Hai said is also true, no matter how strong your personal ability is, if someone wants to drag your feet with an iron heart, you can't make much waves alone.

"Liu Gong said with a smile, this transport plane is completed, and we are one of the few countries in the world that can independently design and manufacture medium-sized transport aircraft."

"That is, with this transport aircraft, it is more beneficial to our homeland security."

Liu Hai listened to the praise of the leaders, and nodded while eating.

"I just don't know if Yingzi has registered various patents for C130, there shouldn't be, so wouldn't my copy of the C130 extended version be able to get an airworthiness certificate in Europe?" Bangs have more on their minds.

"Hehe, the eagle has to come on!"

"Do I want to build a single-engine fighter?" Bangs is now thinking about his DIY fighter.

The engine of the fighter can fully adopt the fighter engine of the Hornet.

In fact, for homeland security defense, a single-engine fighter is sufficient.

Although the twin-engine fighter is good, but in the absence of war, the twin-engine heavy fighter is a gold-swallowing beast.

"But in terms of safety and strength, it is still a twin-engine heavy fighter."

"The shape design of the Su-27, plus the engine of the F18." Bangs had a bold idea in his head.

However, there is no hurry in this regard, because there are other things to do after the transport plane.

First of all, there are semiconductors, as well as batteries, bangs must be prepared to work harder.

The world pattern behind is very different, and the first thing is the economy.

Semiconductors are the foundation of informatization and digital revolution, and we are relatively backward in our previous lives, so we must work hard to catch up in this life.

After three days of testing, Liu Hai handed over the test to the department dedicated to testing engines, and then supervised the rest of the turboprop engine manufacturing himself.

In addition, there are a bunch of other things, and the orders in the supercar workshop have been pressed, which is the big bull that bangs copy.

There is only one cartoon this Christmas, and that is Kung Fu Panda.

The dealer has changed its strategy, this year it is Kung Fu Panda and Gundam, and next year it will be Toy Story in the summer.

Next Christmas, Transformers and Toy Story, the influence and achievements of the two are stronger than Kung Fu Panda and Gundam, so they will combine Kung Fu Panda and Gundam.

Anyway, the follow-up depends on the situation, and the original preparation of Gundam is next year's summer file, so after this change, the domestic production department will work overtime, but fortunately, Liu Hai has already drawn out the character model, removed some obvious Japanese elements, and added some Western elements, including some cold jokes in the dialogue that are not funny in the eyes of us Orientals.

As for the aircraft fuselage and the wing manufacturing workshop bangs, it is more about technical guidance.

And bangs also like to delegate power, that is to say, as long as you have nothing to do, you can do it casually, come to me if you have a problem, it doesn't matter if you mess things up, eat a trench and grow wise.

Although this will waste some materials and increase the cost.

However, because the bangs are all copied mature designs, the R&D funding is too far behind compared with foreign countries.

Therefore, even if there are some failures or accidents in the manufacturing process, it is acceptable.

Bangs also have to design superyachts, the design of superyachts is bangs design, most of the parts and various interior decoration furniture inside, are manufactured on our side, and then taken to Niuniu to assemble.

Liu Hai hasn't cared about international affairs recently, mainly because he's too busy.

In particular, various systems inside the medium-sized transport aircraft, the bangs also reserved a place for upgrading the systems.

This transport plane bangs were originally intended to be digitally controlled, but due to the current semiconductor technology, if digital control is adopted, it will be unstable on the one hand, and safety on the other.

Because digital control requires a lot of flight data to be collected, and continuous testing is required.

This bangs will be handed over to others to do it later, or do it hydraulicly.

As mentioned earlier, there are two sets of hydraulic control systems for the aircraft, and one set is used for backup.

Liu Hai estimated that if digital control is to be carried out, it will take at least a year to collect data, and then make a digital control model based on the collected flight data.

Not to mention the huge variety of sensor data transmission, chips, and control systems.

I'm afraid that the whole system will take several years, and the bangs are not as good as the hydraulic control system.

Let the medium-sized transport aircraft fly first, so that our country has aircraft to use, and then slowly upgrade.

When the bangs crossed, the plane with a lot of geese next door still did not have a digital system, and the main one was durable.

On October 23, 1977, it was frost and it was also Sunday.

However, in recent times, bangs have not had time to put on Sundays.

Even the people in other workshops of aircraft manufacturing did not have time to rest, and Sundays were at most rotational rests.

Just after eating at noon, Liu Hai made a new cup of tea.

"Big brother, I'm here!" As expected, the little junior brother came running again.

"Is your homework done?" Bangs have to ask every time.

"Not yet, I'll write it with you." The little junior brother shook his head.

Bangs took out the pineapple soaked in salt water from the refrigerator in the next room.

"Thank you, big brother!"

"Let's eat."

"Where to eat at night?"

"I'll go home and eat in the evening." Liu Hai heard the little junior brother say this, so he didn't ask.

The room was already heating inside, and the little junior brother also took off the thick clothes outside, and the bangs hung up.

In the past few months, the little brother's dress has become better and better than before.

Now that the supply of materials in the market is becoming more and more abundant, and a wage adjustment has been carried out across the country, some types of goods have begun to be purchased without restrictions, and there is no need for tickets.

Especially for some industrial products, the first thing is that there are no tickets for bicycles, and then there are no tickets for chemical fiber fabrics, but for cotton cloth and the like.

Some small household appliances do not need tickets, rice cookers, televisions, electric fans and the like.

The younger brother wore small leather shoes, corduroy pants, and a sweater on the upper body, because the room was relatively warm, so he took off the thick coat outside, and then found his own exclusive place to do his homework and began to write his homework.

He also took a sorghum stalk threaded with a rope and pulled it next to him to count.

And sometimes they put their hands out, like those who tell fortunes, and dot on them.

I almost laughed when I saw the bangs.

Zhu Haiyang was working in the study at home, and the master came in with a cup of tea made of wolfberry and jujube.

"My daughter is busy in the kitchen again." Shi Niang said in a low voice.

"Busy with her, we can't take care of it." Zhu Haiyang put down the pen in his hand, took off his glasses and rubbed the bridge of his nose in the middle of his eyes.

"Alas!" Shi Niang sighed and got up, and then massaged Zhu Haiyang.

"The main thing is that Xiaohai is too good, whether it is the younger generation or our generation, almost no one can compare, as early as a few years ago, there were leaders who joked that Xiaohai alone can be worth ten divisions, and this was laughed at by other leaders."

"If there are enough ten divisions, our motorcycle factory alone has fed more than 100,000 people, not to mention the technologies created, so that we can change from a grain exporter to a grain importer." Zhu Haiyang sighed.

"I don't have any opinion on Xiaohai, the key is that there are too many people in the hospital who want to kiss their daughter."

"My daughter is also old, and there are still gossips from others, I mean do you want to think of a way?" Shi Niang said in a low voice.

"It's not good for us to come forward in this matter, and when will you ask your girlfriend clearly, if she is really interesting, let's find a way to say it." Zhu Haiyang is still not sure.

"You still don't understand, our daughter is 25 years old this year, and it's not that there are no young men in our hospital, and it's not that there are no young men in the university." Shi Niang angrily hammered Zhu Haiyang's shoulder.

"After Xiaoyun came back and left, my daughter had to cook by herself every Sunday, where could the two of us eat the food cooked by my daughter." Shi Niang said again.

"This thing is not easy to do, you said that if the girl is willing, Xiaohai is unwilling, how can we see each other again in the future?" Zhu Haiyang also felt that his head was big, but he didn't think there was anything wrong with bangs being old, as far as bangs' current achievements were concerned, I don't know how many girls would like them, let alone more things that bangs don't know about.

"Why don't you find someone else to probe the story?"

"This matter is not easy to do, I don't think Xiaohai has this mind, you see that after our daughter is older, Xiaohai will take the initiative to reduce contact a lot."

"Find someone close to Xiaohai, he used to think about his ex-wife, and now his ex-wife is not coming back, no matter how you say it, you have to find one, if you don't want to, forget it, otherwise our daughter will be 30 years old in a blink of an eye." Shi Niang was anxious, after all, seeing that her daughter was getting older and older, there was a lesbian in the unit who was 25 years old and not married, and if she didn't get married, it was not a good phenomenon within the organization.

"I'll think about it, you go and see what she does, don't make it delicious." Zhu Haiyang waved his hand a little irritably.

When the master heard this, she beat Zhu Haiyang, and then went out.

After five o'clock in the afternoon, Liu Haisheng stretched his waist, and Liu Hai was recently working on the battery on the side.

In 1976, the production process of the first commercial lithium battery was registered, but unfortunately this lithium battery can only be used as a button battery, because in the subsequent research and development and manufacturing, large lithium batteries will explode when charging.

Because lithium dendrites will grow during the charging and discharging process of lithium batteries, this thing will penetrate the lithium battery like metal, and then cause a fire and explosion.

Then it was not until 1996 that lithium iron phosphate was discovered, and then lithium batteries really entered thousands of households.

"When the aircraft is finished, I will do the test myself." Liu Hai is now only engaged in theoretical research, and will not come to do experiments until the end of aircraft construction.

"Senior brother." As soon as Bangs had put his things away, a voice came.

"Senior sister is here!"

"This is the balls that my mother fried with me, you can take them home and eat them." The younger sister pushed the door and came in, wearing a windbreaker and carrying an insulated lunch box in her hand.

"Thank you, sister, thank you on my behalf." Bangs took the lunch box.

"Sister, why did you come, I want to go back to watch cartoons." The little junior brother stuffed the old comic book he had flipped in his hand into his school bag, and then complained.
