Sun Aiguo had to be shocked, was that an airplane?

Can you build planes in this factory yourself?

"Director, the technical term is piston engine, that is, the internal combustion engine we built, which was this kind of aircraft during World War II." Liu Hai was so shocked when he saw Sun Aiguo, and quickly explained.

When Sun Aiguo heard this, he became interested and hurriedly asked, "Can you tell me in detail?" ”

"Airplanes were originally in-line piston engines, just like the ones used in our vans, which can build airplanes."

"Later, there was a star engine, which is the piston around ......." Liu Hai took a piece of paper and drew it.

"The third is the kind of V8 engine that is similar to the leader of ZTE."

"The fourth is an opposed-piston engine."

"They have their own strengths and weaknesses...!" Bangs explained the advantages and disadvantages of the four engines in detail.

Sun Aiguo, who had already heard the wide-eyed widening beside him, asked, "Can the engine of our van really build an airplane?" ”

"Of course, you can, but the difficulty of the aircraft is not the engine, but the overall aerodynamic layout, and this new engine needs a wind tunnel." Bangs explained the wind tunnel again.

In fact, wind tunnels are also divided into sizes and configurations, and small wind tunnel motorcycle factories can fully support them.

But there was no need, the bangs were originally going to be copied.

The reason why Liu Hai wants to make a piston engine is mainly because of the current level of domestic working conditions, that is, to make a turbo engine, follow-up maintenance, etc., which is also a big trouble, and the current national strength cannot support such a huge expenditure.

Turbo pulp, turbojet, turbofan, turboshaft these engines need to be supported by the overall manufacturing industry, not only engine manufacturing, but also overall aircraft manufacturing.

Even if Liu Hai takes out the turbo engine now, what is the use, without a super-large forging press and casting press, the aircraft manufactured is an inferior industrial product.

There is also the overall structure of the aircraft, the design, the manufacture of all aspects are not good, and a single engine is useless.

The cost of piston engines is low, the maintenance costs are also low, and the maintenance technical requirements are not high.

There are no decent aircraft in the country, it would be nice to have a piston engine.

When Sun Aiguo heard Liu Hai say so much, he was shocked by Liu Hai's knowledge reserves, and at the same time he was puzzled: "According to what you say, it is very difficult to manufacture?" ”

"Start small, that is, the kind of one or two people, if you succeed, of course it's good, if you fail, you should accumulate experience." Liu Hai originally planned to make that kind of small plane first, the kind of fixed-wing small plane that I see now, the kind that refuels at a gas station.

It is impossible to come up and make an accident with a large piston transport plane with two or three thousand horsepower.

In fact, the piston transport aircraft has a very long lifespan, look at modern Africa, there are many places where passengers and cargo are used, and there are also some special aircraft, such as fire extinguishing and the like, can use this.

"No problem, you can do it yourself." Sun Aiguo naturally agreed when he heard Liu Hai's words, and imagined in his heart that he could also fly a plane to the sky in the future.

Regardless of whether it is a big plane or a small plane, as long as you can build an airplane, it is definitely much more high-end than building a car.

"I'll try it here, and I won't alarm other departments, so as not to fail and be laughed at." Bangs hurriedly said.

"Let's see what you do, how convenient you are." Sun Aiguo felt that Liu Hai would definitely bring good news to himself, although the young man in front of him, although he said that he might not be successful every time he designed and studied, but in the end he succeeded all.

Sun Aiguo left, and there were a lot of things on his side, but on the way back to the factory office, he walked fluttering, looked up at the sky from time to time, and wondered in his heart: "I forgot to ask Xiao Liu if the plane is good to drive?" And how high can you fly? Too tall and your feet are soft? ”

The next day, the people from the maintenance department came back, and Liu Hai was also relieved, and quickly distributed the drawings to them.

The skills of the people on the side of the maintenance department are divided into three gears, and the first Li Dali and the three of them are responsible for the guidance and final finishing, and the last group of people to do some rough work.

Anyway, if it is broken, you can work overtime and do it again, and the bangs are a bit similar to the concept of responsibility system, that is, this part is handed over to you, and if you do it badly, you will do it again.

Bangs continue to design the gearbox, and other bodywork and so on.

—————————————

While Liu Hai was busy making sports cars in Kyoto, on Hong Kong Island, Mr. Huo was waiting for last year's financial settlement.

This financial settlement, Mr. Huo will take to the mainland to report, because Mr. Huo's Sihai company's profits, the mainland has a part, and it still accounts for the majority.

This is also why the mainland gives Mr. Huo the cost price, let Mr. Huo increase the price himself, and then the company's profit is shared with Mr. Huo in the mainland, which is about 28, and Mr. Huo occupies 20% of the profit.

However, Mr. Huo is going to the mainland this time to change it, as for how much will it occupy in the end? Mr. Huo's psychological bottom line is 2%.

Don't underestimate this 2%, according to the current market, 6 million small displacement motorcycles a year, 125,250 motorcycles and 200,000 motorcycles, 10,000 cars, and countless small household appliances, excavators and 200,000 marine thrusters.

In addition, there are some scrap iron and the like that cannot be registered, and this kind of profit is not low.

Moreover, Mr. Huo still has a factory to produce accessories, and this profit is not in the profits of the mainland.

And without the support of the mainland, Mr. Huo knew that his business would not be so big, and all the materials used to build the port were from the mainland, and the price was really the price of cabbage.

In addition, these workers in their own factories are their own fellow villagers, and many of them have seen blood.

"I wonder how the car and sports car are made?" Mr. Huo is not very worried here, most of the products are made in the mainland, and there are a group of sub-distributors in sales.

Regardless of buying and selling, I am a middleman.

Of course, Mr. Fok also has an advantage on Hong Kong Island, that is, the foreign exchange in his hand does not need to be exchanged for the currency of the mainland at all, and he can directly exchange it for some equipment or something he needs on Hong Kong Island.

If you use the mainland's own money to exchange for foreign exchange, and then buy more things in the equipment.

Moreover, the price of the same equipment purchased by the mainland and the dealers of Sihai Company is completely different.

A set of large chemical equipment, the mainland to come forward to buy, may require 200 million foreign exchange, or even more.

But when these dealers of Sihai Company go to buy, the price is unimaginable, and this is still a quotation, as for the real purchase price, I don't know at all.

Several parties have benefited from the coming and going, and the mainland has bought more equipment with the same money, and those dealers have also made a lot of money.

At the end of January '64, Mr. Huo got last year's financial statements, and then set off for the north.

At this time, the mainland had already sent 10,000 motorcycles to Hong Kong Island every day, and there was an endless stream of cargo ships carrying goods from the Pearl River to Hong Kong Island day and night, but the sailors on both sides seemed to turn a blind eye, and the fishermen on Hong Kong Island acted as an eyeliner, and once a suspicious vessel appeared in this sea area, they would immediately report it.

Then the sailors on Hong Kong Island would drive the gunboats to see who was here to do something.

When Mr. Huo came to Kyoto, Liu Hai was assembling the first V12-cylinder engine with 515 horsepower.

Sun Aiguo is watching the bangs here for the final inspection, 515 horsepower, what is this concept?

Sun Aiguo looked at the engine in front of him, and was very nervous for no reason, a few years ago, how much horsepower did the motorcycle factory make?

How much horsepower is the diesel engine that comes out of the back?

A 12-cylinder gasoline engine has more than 500 horsepower, what does this mean?

Ahead!

Leading the world!

These are the eight words that Sun Aiguo thought of, and only these eight words can be described, of course, the premise is success.

"How many horsepower engines do our tanks use now?" A thought flashed through Sun Aiguo's mind.

The bangs were put to the last check, and after all the checks were in place, the oil was ready to start.

This is also installed with electric start, using a large battery, but there is no way that there is no modern power battery.

"When will the battery technology be upgraded?" Liu Hai looked at the lead-acid battery in front of him, thinking about when to look for it on the aircraft carrier, there should be battery-related things.

This is naturally air-cooled.

This machine was specially taken to the test place, and there are already more professional procedures for test running here.

Bangs press the switch, and the starting motor drives the V12-cylinder engine.

With a roar and a puff of smoke, the 12-cylinder engine was successfully started.

After only ten seconds of starting, Bang Hai quickly stopped the machine, because the sound was a little wrong, and then carefully checked and debugged it.

This is the order of the test run, this internal combustion engine is fine.

The first ignition of the aero engine does not exceed three seconds, and then it is necessary to look at various data, and after reading all kinds of data, then the engine itself must be checked, and the second ignition will not exceed ten seconds, and then the various data and the engine are checked again.

In this way, it has to be tested many times frequently, little by little.

This time the engine sound was smooth, Sun Aiguo looked at the V12 cylinder gasoline engine that had started running smoothly, and applauded vigorously: "Okay!" ”

The people in the whole workshop also applauded, and there were only people in the maintenance department workshop and the secretary of the factory director, and no one else.

The maintenance department is relatively special in the motorcycle factory, the surrounding one is remote, and the second is that no one can come in, that is, many people in the factory office can not come in.

"Now this is here to test it?" Sun Aiguo looked at this engine and felt so powerful and domineering.

"Let's test drive first according to the process." Bangs nodded, engine test run is a must, how many hours is the test run? Observe the condition of the oil and the various parts.

"Okay, how long do you expect the sports car to take?" Seeing that it is almost February, there are still ten days to go before the New Year.

"The parts for the second one are almost ready, and they will be ready to be assembled in a week." Bangs spoke.

"How long will it be on your lover's side, don't ignore it then?" Sun Aiguo asked Liu Hai about the family again.

"My lover's side will not be delayed in the New Year." Bangs knew that it was the child's date of birth that was being asked, and immediately spoke.

"Well, I'm waiting for your good news!" Sun Aiguo didn't say much.

"Recently, my side has been too busy, and now it has not reached 20,000 units per day, and the reservation order on Hong Kong Island for small displacement motorcycles has always been 200,000, and there has been no change at all." Sun Aiguo said as he walked outside with bangs.

The workshop for the test run is separate in the maintenance department, and Liu Hai arranges a special person to watch here.

"Factory director, you go and get busy, I don't need you to worry about it." Bangs have a plan here, and the sports car can be assembled before the Chinese New Year.

Backed by a large factory of more than 50,000 people, no matter how complicated the shape of the car cover taken out by the bangs? The senior skilled worker knocked out the hammer for you.

In terms of automobile manufacturing, the most difficult thing to make is the mold, but with the backing of a large factory with tens of thousands of people, it is no problem to make molds.

Special tires, special wheels, and body coverings.

Everything is basically complete, and the gearbox is basically completed, but the final assembly remains.

Assembly of the second engine starts tomorrow, and when it is completed, it will be commissioned, and then the gearbox and the whole vehicle will be assembled.

"I believe in you, when your sports car is built, let Mr. Huo come to visit." Sun Aiguo walked out of the door and said a word, and then left in a hurry.

Bangs returned to the maintenance department, and the others hurried to work, mainly to do the final inspection of the engine parts and gearbox parts, and start assembling them tomorrow.

Liu Hai entered his office, and the drawings of the whole vehicle had been completed half a month ago, and the front was to send the drawings to various departments while drawing.

For example, the size and requirements of glass, wheel tires, these are all made in advance.

Bang Hai is now drawing a 4-cylinder opposed gasoline engine with only about 110 horsepower, which is the power system of a small aircraft.

The power system of the aircraft is only a part, the whole aircraft also has a control system and so on.

The bangs are a reference to one of Hyundai's small aircraft, the Apollo LSA.

The wings are above, and the view below is wide, and it is possible to perform some observation missions and the like.

There is no worry about the bangs on the side of the sports car, there are more than a dozen people in the maintenance department, and it is very fast to assemble the vehicle.

"We will make this small plane in the first half of next year."

"Then the year after next you can make a bigger twin-engine transport aircraft."

"After that, you can make a four-engine large transport plane."

"Let's make a piston engine for the time being, and we'll talk about the rest later." This is Bangs' temporary planning in terms of aircraft.

"Mr. Huo, when he arrives in Kyoto, when he is free, I will ask him to come to dinner at home, and then we will write the relevant agreement." When I went to my father-in-law's house for dinner in the evening, my father-in-law said to Liu Hai.
