Chapter 186 Development of a speedboat Yaogang Hotel

Li Yunhe was obviously unprepared, he didn't expect the car to be so complicated, and asked: "Mr. Zhang, can we make the simplest car first, don't make it so complicated?" ”

"These are necessary for the cars we build to be safe to drive. Otherwise, no one would dare to drive it. Zhang Zhimu said: "This is the simplest introduction, you should listen patiently!" ”

Zhang Zhimu knew that Li Yunhe and the others were not mentally prepared to do such a complicated thing. Although it is possible to start with the kind of walk-behind tractor that the Chinese produced the most in the previous life, Zhang Zhimu did not, and he hoped to build something that could be used now. Because of the role of that small tractor, it can now be completely solved with livestock.

Li Yunhe stopped talking. Zhang Zhimu went on to say: "

The chassis receives the power of the engine, makes the car move, and ensures that the car runs normally according to the driver's control. The chassis consists of the following parts:

Drivetrain – Transfers the power of the engine to the driving wheels. The drive train includes components such as clutch, transmission, drive shaft, and drive axle.

Driving system - the assembly and parts of the car are connected into a whole and play a supporting role in the whole car to ensure the normal driving of the car. The travel system includes components such as the frame, front axle, housing of the drive axle, steering wheels and drive wheels, front suspension and rear suspension.

Steering system - to ensure that the car can drive in the direction selected by the driver, it consists of a steering gear with a steering wheel and a steering transmission device.

Braking system - to slow down or stop the car, and to ensure that the car can be reliably parked after the driver leaves. The braking equipment of each automobile includes several independent braking systems, and each braking system consists of an energy supply device, a control device, a transmission device and a brake.

The body is the place where the driver works, as well as the place where passengers and goods are loaded. A typical truck body includes parts such as the front panel, cab, and cabin.

Electrical equipment consists of a power pack, an engine starting system, automotive lighting, and signaling devices. ”

These contents can be told by all those who can drive in their previous lives. But if you don't explain all the principles and details, you won't be able to explain much. Zhang Zhimu couldn't say it. He can only talk about what he understands, and if he doesn't understand, he can only introduce the principles, or introduce the purpose of these things to be solved and the functions to be realized, so that they can study them slowly.

Watching everyone finish taking notes, Zhang Zhimu continued: "

Regarding clutches and transmissions, we have been in contact with them when we are engaged in lathes. I won't talk much about it, but the car we're working on now is simpler, let's set it to three gears, high, medium and low, plus one reverse gear.

Our car is first made of front-engine, rear-wheel drive.

The drive axle is generally composed of a final reducer, a differential, a wheel drive and a drive axle housing. Its function is to fold the power transmitted by the universal transmission device through a ninety degree angle, change the direction of force transmission, and reduce the speed by the main reducer, increase the torque, and distribute it to the left and right half shafts and the driving wheel through the differential.

The transmission device and reducer have been touched before, and it is this differential that needs to be talked about.

If you look at the four wheels of this car, when they turn, the travel of the left and right wheels is different, which means that if their speed is the same, one wheel will slip. In order not to slip the wheels, we have to make the two wheels rotate at different speeds. This differential has three major functions: one is to transmit the power from the engine to the wheels; the second is to act as the main reduction gear of the car, reducing the speed of the drive train before the power is transmitted to the wheels, and the power is transmitted to the wheels; The third is to allow the two wheels to rotate at different wheel speeds.

Let me tell you about the principle of the differential. ”

Regarding the principle of the differential, Zhang Zhimu finished talking about it for a long time. But it can be seen that everyone is not very clear, Zhang Zhimu decided to make a model, so that everyone can take a look at it intuitively. After class, Li Yunhe arranged two carpenters, and the carpenters cooperated with Zhang Zhimu for two days to make a differential model that satisfied Zhang Zhimu.

When Zhang Zhimu brought this differential model to the class, everyone watched the model carefully, and after turning the experiment with their hands, they realized that it was still very simple to understand this thing.

In the future, everyone will develop a habit of working together to make an intuitive thing for those things that are not very simple. In this way, everyone's understanding is very clear.

Li Yunhe later suggested that these models should be sent to Yaogang College. Let the students use it while studying.

When Zhang Zhimu talked about the steering system, he made a model in advance. Let everyone know that when steering, you must use a trapezoidal bogie to ensure that the two wheels in front do not slip when steering.

Zhang Zhimu knew that this was all he could tell everyone.

However, seeing that Li Yunhe was particularly interested in this matter, Zhang Zhimu said: "Yunhe, you can be distracted by the car, but don't fall into it." Because you've got too much to do. In particular, after your diesel engine is well used, you still have many application fields. ”

"You're talking about it on a ship?" Li Yunhe immediately understood what Zhang Zhimu meant.

Zhang Zhimu smiled and said: "You see that compared with the steam engine, this diesel engine is small in size and has great power. Is it possible to build a high-speed speedboat? It doesn't need to be too big, you can put down the diesel engine, and you can take a few people with a speedboat? ”

"Great idea! Please Mr. Lin and Mr. Lu, let's study what kind of speedboat to make. We can build it in less than a year. Li Yunhe is very confident.

Zhang Zhimu said: "Such a small boat can be equipped with two of our steel-hulled boats. It's a pity that we still have too little aluminum, otherwise it would be more convenient to build ships with aluminum hulls. ”

"Let's build a wooden boat first! In this way, our technical side is focused on diesel engines. Just equip the boat with propellers. Although Li Yunhe is confident, he is still very cautious.

"You diesel engine people should be divided into two, half of them will continue to improve the diesel engine and design new diesel engines of different powers, and the other half will start to develop gasoline engines. With gasoline engines, we can not only build gasoline cars, but also airplanes. Zhang Zhimu said.

"Airplanes? Flying machines, you say? Li Yunhe was a little unconvinced.

"What's the matter?" Zhang Zhimu said: "In the future, we will build flying machines. Such an aircraft can fly hundreds of kilometers per hour. With the plane, we went on a plane where we wanted to go. Don't worry, there's a lot more to it and you need to take your time. ”

Li Yunhe heard Zhang Zhimu say this, and his hands trembled a little. He knew that Zhang Zhimu never said that it couldn't be realized, but he still couldn't understand when the machine flew up.

Zhang Zhimu saw that Li Yunhe was a little dumbfounded, and said, "Hurry up and call Mr. Lu Bingyi and Mr. Lin to make an appointment." Let's study together, what kind of speedboat to build? ”

Lu Bingyi and Lin Zongwei both saw the news that the diesel engine can operate normally on the "Kiln Gang Reference", and they all know that this diesel engine is a power machine with small size and high power, which is easy to start and stop. But none of them have yet to consider it for use on board.

When they came to Zhang Zhimu's office and heard Zhang Zhimu say that he wanted to build a speedboat powered by diesel engines, they were all a little surprised!

Zhang Zhimu said: "In the past, we used small steam gas engines to build speedboats. The speedboat is only a little faster than our steamboat. Now the speedboat we build is a real speedboat, and when it runs at full power, the boat can fly close to the water. Therefore, the shape of our speedboat should consider both underwater resistance and wind resistance. That is, there should be a streamline under the water, and there should be a streamline in the water part. The front part of the boat for fast sailing must have glass to protect the wind and water. My idea is that we should have two of these speedboats on our steel-hulled boats, and there should be a device on board to retract and release the speedboats. ”

Lin Zongwei is very interested in such a speedboat on board, "If there is such a speedboat on a big ship, it will be too convenient to encounter anything." However, such ships are fueled by kerosene. We also have a special place to put diesel fuel on our ship. Besides, will our diesel fuel be able to meet the supply? ”

"We have no problem supplying diesel fuel for a few small boats. At present, it cannot meet the oil consumption of large diesel engines. Zhang Zhimu said: "In the future, if we find an oil field and can exploit fierce fire oil on a large scale, we can develop a large diesel engine." In the future, our big ships will also be powered by diesel engines. ”

Lu Bingyi said: "Large diesel engines are a matter of the future. In my opinion, Mr. Lin still determines how big it is according to the size and location of our steel-hulled ship. Then, according to the size and location of the ship, Li Yunhe arranged the design of the diesel engine. We can build a few more of these speedboats for transportation. Before the battle, he went out to reconnoitre, but the enemy couldn't catch up if he wanted to. ”

Lin Zongwei said: "Okay! I went back to the Lingshui shipyard to take a look at the boat, and I gave a request for a speedboat as soon as possible. Let's move on to the design of the speedboat. ”

Zhang Zhimu said: "I have a request for the speedboat, that is, there must be a place to play the radio station. ”

"Good! It's so convenient to have a radio station. Lin Zongwei said.

"Mr. Lin, tell me about the progress of our first steel-hulled ship?" Zhang Zhimu has always been very concerned about this first ship.

"Mr. Zhang rest assured, we are guaranteed to be able to enter the water before autumn. Now that the upper deck has been completed, the guns will soon be hoisted. Lin Zongwei was very excited when he talked about his steel-hulled boat.

"By the way, Mr. Zhang, our artillery will be hoisted on the ship in the next two days, will you participate in this ceremony?" Li Yunhe asked.

"Forget it! I'm not going. When I go, everyone has to stay with me. I'll wait for the launching ceremony of our boat. Zhang Zhimu said: "The six cannons have been transported?" ”

"Yes, they all have to be assembled on the dock with the turret and hoisted to the ship with a gantry crane." Li Yunhe said.

"Mr. Zhang, I have a suggestion. We should build another dock for steel-hulled ships. By building this ship, we have trained a large number of skilled workers. Especially hydroelectric welders. After this ship is built, we are quite capable of building two more such ships at the same time. Moreover, the construction period of the next ship will be greatly shortened, and the detours and rework of our ship can be avoided, and there can be many improvements. ”

Li Yunhe also said: "Some things can be made at the same time to save a lot of time and materials. I agree with Mr. Lim. ”

"Good! Then make up your mind to do it. Zhang Zhimu said: "In the future, you can make a report on such a thing, and I will approve it." ”

"Also, the sand dredging boat we built is ready to be launched. Do you want to have a ritual too? Lin Zongwei said.

"Inform Tang Jingyao of this matter. The ship is at their disposal, and they organize a small ceremony. Zhang Zhimu said.

"One more thing, Mr. Zhang, do you want to give us a name for this steel-hulled ship!" Lin Zongwei asked.

"Yes! That's a big deal. Lu Bingyi also said.

Zhang Zhimu thought for a moment and said: "I think the ships of our navy will have a unified numbering and naming method in the future. Transport ships, training ships, and combat ships should all have a unified number, so that everyone can know what the ship is used for as soon as they hear the number. As for naming, there should also be some rules. I'll think about it again. It is also necessary to respect Commander Fan's opinion. ”

"It's still Mr. Zhang's comprehensive thinking." Lin Zongwei said.

After Yan Boju and his team went down to the prefectures and counties, Zhang Zhimu felt that the kiln gang seemed to be much quieter all of a sudden. Zhang Zhimu believes that these elite soldiers will definitely play a great role in completing the election in various places. Now it is time to think about Shaanxi, and there is still a year and a half to prepare according to the plan. In fact, Zhang Zhimu was not too worried about military preparations, because at present, with the military strength of Yaogang, no one could stop the attack of Yaogang. The problem is that Zhang Zhimu's idea is to digest a place when he takes it. It is necessary to quickly turn the place taken into one's own rear, not a burden. This requires preparation. Recently, a lot of literate people have come from all over the world, and Zhang Zhimu wants to organize them to train them well. In the future, the cadres who will be drawn back from various parts of Shanxi will all have practical work experience, and it will be very easy for them to take over all parts of Shaanxi, and at the same time, they will also send these newly trained cadres to them as assistants, so that these cadres will also be brought out. In the future, if we develop in that direction, we will have a number of cadres who can be used.

There is still one year to expand the forces of the Western Expedition from next year. Now the strength of Yaogang is sufficient for self-preservation, but the large-scale offensive will have to expand the troops. Weapons and ammunition will be prepared slowly this year. Food should also be prepared early. Shaanxi has also been plagued by disasters for several years, and with food in the past, it will soon be able to stabilize the hearts of the people there.

Just when Zhang Zhimu was about to give a lecture to Yangchang first, Jiang Ji, the general soldier of Datong, sent a telegram, saying that he was going to accompany the acting king to Yaogang recently. Hearing the news, Zhang Zhimu was very happy. This time, I want to give the acting king a good reception, because if you don't fall out with the court now, you have to have a good relationship with the acting king and Jiang Ping. They are in charge of defense in the north, and they don't have to worry about the threat from the north when they divide their forces to the west. This time, I want to reveal it appropriately, but I must not say it too clearly. Otherwise, your own arrangement will leak out.

In order to receive the acting king, Zhang Zhimu asked Liu Bensheng to clean up and let the Yaogang Hotel open as soon as possible. There is something imperfect and rectified while opening.

The opening of the Yaogang Hotel, which everyone has been looking forward to, is a big deal. Before the opening, "Yaogang Weekly" made a very comprehensive report on Yaogang Hotel. Many of the facilities in the Yaogang Hotel are something that everyone has never heard of.

Therefore, as soon as the news of the opening of the Yaogang Hotel came out, many people were trying to get an invitation to the opening ceremony.

At this opening ceremony, many leaders of Yaogang were not at home. Zhang Zhimu asked that the number of people at the opening ceremony should not be too large, and it should be both grand and not too extravagant. However, some celebrities in Shanxi, Zhang Zhimu still asked people to invite. They are all potential guests of Yaogang Hotel.

The night before the opening ceremony, the guests all stayed at the Yaogang Hotel. This was an eye-opener for the guests, and the elevator with a green digital display of the floor number made them curious for a long time. Some people even sit up and down a few times and still feel that it is not enough. The level of service of the hotel's service staff is something they have never seen. Those handsome men and beauties are all dressed in standardized clothing, and they all look particularly solemn. There are many facilities in the hotel that they have never heard of, such as indoor swimming pools, sauna rooms, billiard rooms, gyms, where have they ever seen them. The hotel has restaurants of various cuisines from the north and the south, and it can be said that there is everything to eat, whether it is flying in the sky or running on the ground. In particular, a lot of seafood and freshwater fish and turtles are raised in glass tanks. The kind you want to eat as soon as you order it out and make it for you right in front of you.

In fact, you don't need to enter the hotel, as soon as you enter the door, you will already let the guests know that this is not an ordinary place. The steps in front of the hotel are all polished white marble. The gates are all glass. The lobby floor is made of marble and wax. The lobby is decorated with a variety of exotic flowers and plants. Those rich people who thought they were very valuable only found out that their compound, which they had always been very satisfied with, was simply a slag compared to here.

The guest rooms in the hotel were even more unexpected. There was hot and cold air in the room, twenty hours of hot water, a telephone that many of them hadn't used, and a radio. Standing on the balcony of the room, you can have an overview of the kiln.

The banquet after the opening ceremony surprised the guests. When the opening host announced the end of the ceremony, he informed the guests to go to the top floor of the hotel for a buffet.

The guests didn't know how to eat this buffet, but they were too embarrassed to ask. Familiar people ask each other, but they don't know. If you can't help it, just line up to take the elevator and go up to the restaurant on the top floor.

This buffet was designed by Zhang Zhimu himself. Now there is no stainless steel here. Zhang Zhimu asked people to make a small pot out of copper, in order to prevent copper from harming people. He also had tin hung in the copper pot. The solid alcohol block under the pot was made by Zhang Zhimu and Qingfengzi.

In fact, solid alcohol is easy to make.

Slowly add the vinegar to the calcium carbonate until no more bubbles are produced. Acetic acid reacts with calcium carbonate to form calcium acetate, water, and carbon dioxide. The resulting solution is evaporated to make a saturated solution. Slowly add alcohol to the solution. After the solution is cooled, solid alcohol can be obtained.

This is made by using the principle that calcium acetate is insoluble in alcohol and the two are mixed to form a gel.

After each guest is seated, a waiter will come over to show them how to use the alcohol pot, and then ask for their opinion, and give them a small pot with different pots. After the bottom of the pot was brought up, the waiter lit the alcohol pot with a piece of fire. Looking at the small flames that did not smoke, the guests felt very novel.

The big tables were filled with all kinds of ingredients and spices, which they had to line up to pick up and bring back to eat in their own pots.

There is also a selection of drinks and freshly squeezed juices next to the table.

This way of eating is not only clean and hygienic, but also allows you to pick up what you want to eat. After getting used to it, the guests said it was a great solution.

Although everyone was eating lively, there were still guests who were not satisfied.
