"Mineral water by the way?"

"Instant noodles with mineral water?" Bangs thought of the largest consumer product in the West, water.

That's right, Liu Hai has been abroad all his life, and the fastest selling in supermarkets are two necessities, one is water and the other is toilet paper.

Because of the vast land and sparsely populated abroad, it is generally a warehouse supermarket, that is, it is basically a few kilometers away from home, and the trolley is for this invention, because it is too much to buy at one time, and it is impossible to take it.

The cart takes up the bulk of the water and toilet paper.

In the past, there were people who brag about how strict the tap water in the West is, and why don't these people say that the heavy metals in the Great Lakes region are almost extinct? (Hasn't it been a few years since the Niuniu nuclear leak was leaked recently, what about the so-called right to know?) It's no wonder that these people don't object to the little book, because they have been doing it themselves for a long time. ）

In the West, it is better to drink bottled water, otherwise the chance of baldness is too high, and of course it may be a conspiracy to deliberately make the tap water bad and facilitate the sale of bottled water.

However, Liu Hai has no time to care about this for the time being, whether it is the development of cold water blisters, or self-heating packs, it will be said later, because the helicopter assembly is about to be carried out, and in a few months, the helicopter factory in the Northeast has successfully manufactured the rotor designed by Bangs.

Although there are still some helicopter parts that have not been manufactured, but the final assembly also takes time, the final assembly adopts a rivet structure, riveting this is divided into many riveting methods, there are hot riveting, cold riveting and so on.

For example, when we install windows at home, they are basically cold riveted, such as window handles and the like.

And the general large buildings, such as some early iron bridges on the rivets, are burned red, and then riveted with equipment.

The Black Hawk helicopter has a semi-monocoque design, that is, the fuselage skin also bears weight and tension, and the reason why it is designed this way is actually for defense.

Even if titanium alloy is used in the later stage, it also needs a certain thickness to be bulletproof, so the semi-monocoque design is adopted, and the fuselage structure of the Figure 22 aircraft is also a semi-monocoque design, and the entire lower belly of the fuselage is titanium alloy, which is not only bulletproof, but also increases the overall strength, especially the section where the pilot is located, which is thickened.

Of course, there is no way to do this sample of bangs for the time being, only aluminum alloy is used.

Liu Hai sorted out a few people from the maintenance department of the turboshaft engine workshop, and then mobilized a few skilled workers from the aircraft workshop of the motorcycle factory, mainly assembly workers.

These skilled workers have undergone strict management in the aircraft factory and are very experienced, Liu Hai will not recruit any new workers to come in, newborn calves are not afraid of tigers, Liu Hai is most afraid of these novices.

Because some novices always like to follow their own ideas, thinking that you are redundant here and redundant there, in fact, every word in the assembly manual, there is no superfluous.

Bangs doesn't want to have nothing to explain to these novices, because you just explain, and if you touch their knowledge blind spots, they won't believe it.

What Liu Hai wants now is a worker, that is, an obedient worker, who does what he asks him to do, and as for the principle, he doesn't need to know.

Good technical workers are the foundation of a country, and when the bangs are crossed, why Boeing's plane pulls its crotch is because the equipment workers, especially the excellent workers, are gone.

In the early days, the workers in the Boeing Aircraft Company's manufacturing plant had strict requirements, no criminal record, no tattoos, no drugs, etc., and when it came to the time of bangs, how many such people did Lao Mei have?

On Lao Mei's side, there are very few people who have no criminal record, and the lawn is not well maintained, and if they are complained by neighbors, they may be recorded.

When Liu Hai crossed, he also knew that Boeing's foundry had a lot of problems, but Boeing had to turn a blind eye, because there was no way, just this factory could produce, and if he was not allowed to produce, there was no play, unless he was allowed to OEM in the East...... Ahem.

In an era of financialization in the United States, the manufacturing industry was directly scrapped, and even the rocket engines had to be bought from the neighbors to the north, because they were terrified of their own production.

Bangs officially took the assembly workers to start assembling the helicopter, starting with the frame, Bangs personally got started, let others also participate, all parts are numbered, each part is responsible for the person, and the installation time of each part must be recorded.

As for the follow-up outbound, warehousing, post management, these aircraft factories have been implemented for a long time, it can be said that although the domestic aircraft manufacturing technology is not good, but in terms of management level, directly hanging the world, although it seems that there are indeed a lot of rules and regulations.

Including automobile manufacturing, the responsibility is the same from the storage of parts, how many parts are used in each shift, how much is left, and when there are people in other factories who steal new parts and sell scrap, the motorcycle factory has to find out if there is a screw missing.

Bangs know that there was a rocket launch in our history because a screw fell inside, and the screw happened to fall on a certain circuit when it was moving, resulting in a big problem before launch.

Now it's basically impossible, how many screws are used, how many screws are out of the warehouse, how many are in the warehouse, one less can not get off work, and the installed ones have to be dismantled.

Although it is a little impersonal, a little cumbersome, and a little old-fashioned, it will be of great help to the high-tech industry in the future.

The fuselage covering of the semi-monocoque design is thick and heavy, the rivets are directly hit, and the bulge is convex, there is no problem with the helicopter, but it will not work if you change the stealth fighter, and you need to bury your head and rivet.

Sun Aiguo has been coming to the helicopter equipment workshop every day recently, and Liu Hai starts with the big parts, the power pack, the rotor, the tail and so on.

"Tsk." Sun Aiguo looked at this helicopter day by day, and he was also amazed at the speed of the bangs.

"Xiao Liu's speed, it's simply true." The deputy director in charge of the military industry has been doing chores here for the past few days, well, it is the hot water bottle that runs out of water or something to take the initiative to change, the main one is watching here, and the progress of the bangs to equip the helicopter is also amazing.

Not only Sun Aiguo and the deputy factory director, but also these people in the maintenance department, were also stunned by the speed of their own section chief, and the person in charge of recording next to him almost couldn't catch up.

When the bangs are equipped with a part, the tool is ready, and then let the person who records next to it hurry up to record.

Then pick up the tool, have someone hand the parts to you, and then click the operation, and it's done.

After that, Liu Hai also explained.

"I'm afraid that this helicopter will be imprinted in Comrade Xiao Liu's brain, so it can be so fast." Sun Aiguo nodded and said.

These people know that Liu Hai has disassembled and assembled the Black Hawk helicopter more than a dozen times in the aircraft carrier space, and he has made most of the parts and reassembled them by himself, so the difficulty is naturally very low.

"Genius, it's so fast to get started for the first time." The deputy director in charge of military industry also nodded.

Liu Hai doesn't care about Sun Aiguo's arrival, there are a lot of things on his side, and after the frame is done, it is the entire wiring harness.

The bangs on the harness side made a diagram directly on a huge wooden board, and the entire helicopter wiring harness was completed on this wooden board.

The first is how long the lines of each color are, and then each line has its own number, and each number corresponds to a different joint.

After the connector is connected, the wiring begins, directly on the board, the wiring, the numbered start and end position of each wire is on the board, and all the wiring harnesses are bundled after they are completed.

After the strapping is completed, it is time to test the on/off of each joint.

Most of these joints are precious metals, pure silver, pure gold quite a lot.

Then there is the wiring harness on the machine, this super reduction uses less wire, and the Black Hawk helicopter on the space of the Liuhai aircraft carrier has more than 30 kilometers of wires.

Radar equipment, fire control equipment, and rockets, and missiles are not prepared, and you can just build a general platform by yourself, and it's a big deal to open the interior, and then wiring it.

The harness bangs have been busy for several days, mainly because the work has to be done by themselves, from breaking the wire, making numbering records, etc., to the final strapping.

These wiring harnesses can be handed over to those female workers to do later, this motorcycle factory has a professional electrician workshop, and some vehicle circuits use this model.

Bangs are busy in the dark, the helicopter is the same day a day, a day is the same, when the beginning of July, the entire helicopter sample assembly is completed, Sun Aiguo only found that this thing is really big.

"The helicopter is 5.13 meters high, 19.76 meters long, 2.36 meters wide fuselage, 16.36 meters diameter of rotors, and has an empty weight of 5,820 kilograms." Bangs spoke.

Because of the all-metal construction, although the weight is about the same as that of the Black Hawk helicopter, this is just a platform, and there is no radar or anything.

Plus radar and other things are heavier than the original, this is because the bangs are made of all-metal structure, and the sample helicopter is like this, because theoretically the sample helicopter has not yet been finalized, and it also needs to be tested to find shortcomings and subsequent optimization.

"Okay, let's start the test?"

"Well, let's test on land first, and then we can take off if all indicators are qualified."

"It's mainly the control aspect." Bangs continued to speak.

The control is that the rotor angle of the aircraft will be linked with the operation, although it is theoretically fine, but it still needs to be tested.

"Then test?" Sun Aiguo nodded.

Then the helicopter was towed to the hangar on this side of the small airport, which was the airport that produced single-person and double-passenger small planes, and the runway was very short, which has been basically idle in recent years.

The large airfield is where the four-engine aircraft are tested, and it is still being used busily there.

The hangar here is very large, and the test run is mainly to observe the control system, tail fin, and rotor control.

The helicopter starts the small free turbine, which is to power the helicopter on the ground, and then start the turboshaft engine, after the turboshaft engine is started.

Began the formal test, the oil pipes were connected to the outside for fear of losing control, the plane was also fixed on the test bench, to ensure that it would not move, in addition to Liu Hai and others in the bulletproof glass and stainless steel protective mesh behind the room to observe, once the helicopter has an accident, the rotor is like a super flying knife.

Everyone nervously watched the initial test of the helicopter, if the test was successful, it would be more than half of the success, of course, the experienced helicopter pilot operating in the plane, and the heart was also beating.

But to be able to fly this kind of large helicopter, the test pilots are also very excited, the bangs in the walkie-talkie give orders, the helicopter test pilots look at the operation manual, one by one start according to the take-off procedure to start, but also to observe the instrument, if something is wrong, immediately turn off.

"Is that okay?" After a few hours of testing, Sun Aiguo didn't seem to have any problems, so he asked.

Although Sun Aiguo knows that Comrade Liu Hai is a genius, but this is a helicopter, and he actually succeeded once? That's it, no problem.

"No problem for now." Bangs nodded.

"So when is the earliest time you can test fly?"

"It needs to be tested a few more times, and if it goes well, it will be tested in about a week, and there will be maintenance inspections in the middle." Bangs spoke.

"How long does it take for a test flight to be officially flying?"

"If it goes well, it's also a week, and you still need to carry out load tests, range tests, and so on." Bangs: That's fast enough.

Of course, other people certainly didn't build helicopters so quickly, and the old American Black Hawk started in '72, finalized in '74, and then didn't complete the tests until the next few years, because the tests were not just in one place, there were multiple environments.

"However, it still needs to be tested in various places, and if it is finalized, it may not be until the end of the year at the earliest, of course, you can also build a few more helicopters to go to various places for testing, plateau areas, alpine regions, high heat areas and so on." Bangs continued.

"Build, build." Sun Aiguo immediately made a decision.

"Okay then." Liu Hai nodded, and the factory director must start doing it after he spoke.

Then the next day, the test run began one after another, and the leaders of the higher departments came to see the excitement, looking at the helicopter in this big circle, I was also very surprised, is this thing so big?

Among them, the person in charge of aircraft manufacturing and the logistics of the military department ran the most times, basically every day, and when he heard that this helicopter could be on the plateau, he immediately discussed with Sun Aiguo, so why get two to try it on the plateau?

Although there are twin-engine transport planes on the plateau, after all, there are no helicopters, so the place where the helicopter needs to take off and land does not need to be too large.

The bangs and his gang are very busy every day, testing, recording test data, and then maintaining, checking the condition of each part.

"They don't seem to have tools with them?" The leader in charge of aviation saw Liu Hai and others dismantling the plane for maintenance, and asked suspiciously.

"Comrade Liu Hai has made a tool-free design, and it can be maintained without tools within 20 minutes at the earliest." Sun Aiguo said proudly.

"I*!" The leader in charge of aviation was stunned, you must know that the take-off procedure of the plane must be checked, and there are a lot of tools or something during the inspection, and the inspection is completed in twenty minutes, so don't think about it, do you know how many helicopter inspection items there are?

This is also one of the most classic designs of the Black Hawk helicopter, which is tool-free maintenance.

Of course, this refers to routine maintenance.

Lao Mei has gone relatively far in this regard, and when it comes to the bangs crossing, it only takes an hour for Lao Mei to change the fighter engine, and it only takes three people.

Of course, this design is very explosive now, and the leader in charge of it certainly knows that many parts will often have problems under the continuous disassembly and assembly of tools.

"Go up and have a look?" The leader in charge did not dare to rush forward, and asked Sun Aiguo next to him with a question.

When Sun Aiguo heard this, he touched his neck, and then pointed to the ground cordon: "It is strictly forbidden for outsiders to approach when the plane is maintained!" ”

Sun Aiguo saw the leader's depressed look again, and said: "When Xiao Liu and their maintenance is completed, let's let him take it alone, we, as leaders, can't break the rules." ”
