Chapter 485 So fast (second update)

"Make some mineral water by the way?"

"Mineral water instant noodles?" Liu Hai thought of the largest consumer product in the West, water.

That's right, when Liu spent his whole life abroad, the two most popular necessities in supermarkets were water and toilet paper.

In foreign countries, because of the vast territory and sparse population, they are generally warehouse supermarkets, which are basically a few kilometers away from home. The trolley was invented for this purpose, because it is difficult to carry too much at one time.

The majority of the items on the trolley were water and toilet paper.

In the past, there were people who boasted about how strict the tap water in the West was. Why didn’t these people talk about the excessive heavy metals in the Great Lakes area and the native organisms were almost extinct? (Didn’t the Niu Niu nuclear leakage be revealed for several years recently? What about the so-called right to know? No wonder these people are not opposed to small books, because they have already done it themselves.)

In the West, it is best to drink bottled water, otherwise the chance of baldness is too high. Of course, it may be a conspiracy to deliberately make the tap water bad so that bottled water can be sold.

However, Liu Hai has no time to take care of this for the time being. Whether it is the development of cold water bubbles or self-heating packs, we will talk about it later, because the helicopter is about to be assembled. In a few months, the helicopter manufacturing plant in the Northeast successfully manufactured Rotor with bangs design.

Although some helicopter parts have not yet been manufactured, final assembly also takes time. The final assembly uses a rivet structure. There are many riveting methods, including hot riveting, cold riveting, etc.

For example, when installing windows in our homes, they are basically cold riveted, such as window handles and the like.

In general, the rivets on large buildings, such as some early iron bridges, were burned red and then riveted using equipment.

The Black Hawk helicopter adopts a semi-monocoque design, which means that the fuselage skin also bears weight and tension. The reason for this design is actually for defense.

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

Of course, there is nothing we can do about the bangs sample for the time being. We can only use aluminum alloy.

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

These skilled workers have gone through strict management in the aircraft manufacturing factory and are very experienced. Liu Hai will not recruit any new workers. Newborn calves are not afraid of tigers, and Liu Hai is most afraid of these novices.

Because some novices always like to follow their own ideas, thinking that here is redundant and there is redundant. In fact, every word in the assembly manual is not redundant.

Liu Hai doesn't want to have nothing to explain to these novices, because even if you explain it, they won't believe it if you touch their blind spots in knowledge.

What Liu Hai wants now is a worker, an obedient worker who will do whatever he is asked to do. As for the principle, there is no need to know the principle.

Good technical workers are the foundation of a country. When Liu Hai crossed over, why did Boeing's planes stretch their hips? It's because equipment workers, especially excellent workers, are gone.

In the early days, workers at Boeing Aircraft Company's manufacturing plants had very strict requirements: no criminal record, no tattoos, no drugs, etc. But by the time bangs crossed over, how many people like this were there in the United States?

In the United States, there are very few people with no criminal record. If you don’t take good care of your lawn, your neighbor may complain and your crime will be recorded.

When Liu Hai traveled through time, he also learned that there were many problems with Boeing's foundry, but Boeing still had to turn a blind eye because there was no other way. This factory was the only one that could produce. If they were not allowed to produce, they would have nothing to do. , unless we let the big eastern countries do the manufacturing... ahem.

In an era of financialization in the United States, the manufacturing industry has been completely abolished. Even rocket engines have to be purchased from the neighbor to the north, because the products produced by oneself are used by oneself in fear.

Liu Hai officially led the assembly workers to start assembling the helicopter, starting with the frame. Liu Hai started by himself and let others participate. All parts were numbered, each part was assigned to a responsible person, and the installation time of each part was recorded.

As for the subsequent outbound, warehousing, and job management, these aircraft manufacturing plants have already implemented it. It can be said that although domestic aircraft manufacturing technology is not very good, but in terms of management level, it directly beats the world. Although it seems that it is There are a lot of rules and regulations.

The same applies to automobile manufacturing. From the time parts are put into storage, the responsibility is assigned to each person. How many parts are used in each shift and how many are left. In other factories, there are still people who steal brand new parts and sell them as scrap. The motorcycle factory has one less person. Every screw has to be found.

Liu Hai knows that a rocket launch in our history was caused by a screw falling inside. When moving, the screw happened to fall on a certain circuit, causing a big problem before launch.

It’s basically impossible now. No matter how many screws are used, how many screws are shipped out of the warehouse, how many screws are put into the warehouse, you can’t even get off work if there is one missing one. You have to find out all the screws that have been installed and dismantled.

Although it is a bit impersonal, cumbersome, and a bit old-fashioned, it will be of great help to future high-precision industries.

The fuselage covering of the semi-monocoque design is thick and heavy. The rivets are directly driven on and the bulges are raised. This is no problem for helicopters, but it is no longer possible for stealth fighters, which require countersunk riveting.

Sun Aiguo has been coming to the helicopter equipment workshop every day recently. Liu Hai starts with the big parts, such as power packs, rotors, tails, etc.

"Tsk, tsk." Sun Aiguo watched the helicopter change every day, and was amazed at Liu Hai's speed.

"Xiao Liu's speed is incredible." The deputy director in charge of the military industry has been doing odd jobs here these days. Well, he even took the initiative to change the thermos when the water bottle ran out of water. The main player was watching here. Regarding the bangs equipment The progress of the helicopter is also amazing.

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

When Liu Hai equips a component, he prepares the tools and asks the recorder next to him to quickly record it.

Then pick up the tool, ask someone to hand you the parts, and then click and click, and you're done.

After finishing, Liu Hai also explained.

"This helicopter can only be so fast if it is imprinted in Comrade Xiao Liu's mind." Sun Aiguo nodded.

These people knew that Liu Hai had disassembled and assembled the Black Hawk helicopter more than a dozen times in the aircraft carrier space. In addition, he made most of the parts himself and then assembled them, so the difficulty was naturally very low.

"What a genius. You got started so quickly the first time." The deputy director of the military industry also nodded.

Liu Hai didn't care about the arrival of Sun Aiguo. He had a lot of things to do here. After the frame was completed, it was the entire wiring harness.

On the wiring harness side, Liu Hai made a pattern directly on a huge wooden board, and the entire helicopter wiring harness was completed on this wooden board.

The first is the length of the wires of various colors, and then each wire has its own number, and each number corresponds to a different connector.

After the connectors are connected, the wiring begins, directly on the board. The starting and ending positions of each wire number are on the board. After all the wire harnesses are completed, they are bundled.

After the bundling is completed, it is time to test and test the continuity of each joint.

Most of these connectors are made of precious metals, including pure silver and many pure gold.

Then there is the wiring harness onboard. This super reduced configuration uses less wires. The Black Hawk helicopter on the Liuhai aircraft carrier space has more than 30 kilometers of wires. Radar equipment, fire control equipment, rockets, and missile control circuits are not prepared for Liu Hai. Just build a general platform yourself. At the worst, you can just lift up the interior and then wire it.

I have been busy with the wiring harness for several days. The main thing is that I have to do all the work by myself, from disconnecting the wires, making number records, etc., to finally tying them up.

The wiring harness can be left to the female workers in the future. This motorcycle factory has a professional electrician workshop, and some vehicle circuits adopt this model.

Liu Hai became confused when he got busy. The helicopter looked different every day. When the entire helicopter sample was assembled in early July, Sun Aiguo realized how big this thing was.

"The helicopter is 5.13 meters high, 19.76 meters long, 2.36 meters wide, rotor diameter 16.36 meters, and has an empty weight of 5820 kilograms," Liu Hai said.

Because it uses an all-metal structure, although it now weighs about the same as a Black Hawk helicopter, it is just a platform and has no radar or anything.

In addition to the radar and other things, it will be heavier than the original version. This is because the bangs adopt an all-metal structure. This is the case for the sample helicopter, because theoretically the sample helicopter has not yet been finalized and needs to be tested to find shortcomings and subsequently optimized.

"Okay, are you going to start the test next?"

"Well, we need to test it on land first, and then it can take off only if all indicators are passed."

"Mainly in terms of control." Liu Hai continued.

The control means that the aircraft's rotor angle will be linked with the operation. Although there is no problem in theory, it still needs to be tested.

"Then test?" Sun Aiguo nodded.

Then the helicopter was towed to the hangar at the small airport. The small airport was the airport where single and double small aircraft were originally produced. The runway is very short and has been basically idle in recent years.

The large airport is where four-engine aircraft are tested and is still in busy use.

The hangar here is very large, and the main test is to observe the control system, tail wing, and rotor control.

The helicopter starts the small free turbine, which provides power to the helicopter on the ground, and then starts the turboshaft engine. After the turboshaft engine starts.

The formal test began. During the test, the oil pipes were connected externally to avoid losing control. The aircraft was also fixed on the test bench to ensure that it would not move. In addition, Liu Hai and others observed in the room behind the bulletproof glass and stainless steel protective net. Once the helicopter came out, Accident, this rotor is like a super flying knife.

Everyone was nervously watching the first test of the helicopter. If the test was successful, it would be more than half of the success. Of course, the person operating the aircraft was an experienced helicopter pilot, and they were also excited.

But the test pilots were very excited to be able to fly such a large helicopter. Liu Hai gave orders through the intercom. The helicopter test pilots looked at the operation manual and started following the takeoff procedures one by one. They also had to observe the instruments and shut down the engine immediately if something went wrong.

"Is there any problem?" After several hours of testing, Sun Aiguo seemed to have no problem, so he asked.

Although Sun Aiguo knew that Comrade Liu Hai was a genius, this was a helicopter, and it actually succeeded in one go? This worked, no problem.

"There is no problem for now." Liu Hai nodded.

"So when will the earliest test flight be possible?"

"It needs to be tested a few more times. If everything goes well, it will be tested in about a week, and there will be maintenance and inspections in the middle." Liu Hai said.

"How long will it take for the test flight to be ready for official flight?"

"If everything goes well, it will only take a week. We still need to conduct load tests, range tests, etc." Liu Hai said it quickly enough.

Of course, other people certainly did not build helicopters so quickly. The old American Black Hawk started in 72 and was finalized in 74, and then it was not until a few years later that the tests were completed, because the tests were not just in one place, but in a variety of environments.

"However, it still needs to be tested in various places. If it is finalized, it may not be until the end of the year at the earliest. Of course, we can also build a few more helicopters and go to various places for testing, such as plateau areas, alpine areas, high-heat areas, etc." Liu Hai continued.

"Make it, make it." Sun Aiguo made the decision immediately.

"Okay then." Liu Hai nodded. The factory director would definitely do something if he spoke.

Then the next day when the test started, leaders from higher-level departments came to watch the fun. Looking at the huge helicopter, they were also surprised. Is this thing so big?

Among them, the person in charge of aircraft manufacturing and military logistics came the most often, basically every day. When he heard that this helicopter could be used on the plateau, he immediately approached Sun Aiguo to discuss how to get two of them and try it on the plateau.

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

Liu Hai and his team are very busy every day, testing, recording test data, and then maintaining and checking the condition of each component.

"They don't seem to have any tools for maintenance?" The leader in charge of aviation asked suspiciously when he saw Liu Hai and others dismantling the aircraft for maintenance.

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

"I*!" The leader in charge of aviation was shocked. You must know that the take-off procedure of the aircraft must be checked, and there are a lot of tools during the inspection. The inspection is completed in twenty minutes. Don't even think about it. Knowing the helicopter How many inspection items are there?

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

Of course this refers to routine maintenance.

The United States and the United States have gone further in this regard. When it comes to Liu Hai's crossing, it only takes an hour to replace a fighter jet engine, and only three people are needed.

Of course, this design is very popular now. Of course, the leaders in charge know that many parts will often cause problems when the tools are constantly disassembled and assembled.

"Go up and have a look?" The leader in charge did not dare to step forward rashly 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 warning line: "Outsiders are strictly prohibited from approaching the aircraft during maintenance!"

Seeing the frustrated look on the leader's face, Sun Aiguo added, "When Xiao Liu and the others complete their maintenance, we will let him take care of it alone. As leaders, we cannot break the rules."
