Take the mall to Datang

According to the tests conducted by the Ordnance Superintendent, these five cannons fired at the same time are more powerful than fifty small cannons, very lethal, and even more threatening to heavy armored units.

In addition, there are a large number of grenades. Li Shimin does not want to continue the state of Tubo's repeated invasion of the Tang border. Now that the Tang soldiers are strong and have new weapons, there is no reason not to fight back.

After Song Kangde left, Yuan Shan no longer thought about the matter of the Military Weapons Supervision. Anyway, he didn't know when the third locomotive would be produced.

What he has to consider now is to maximize the benefits of the Lanzhou line. Although the railway construction has nothing to do with him, the Ministry of Economic Development is involved in many fields.

The Zhengzhou Economic and Development Department has established a firm foothold, and will continue to expand in various state capitals.

Chapter 663 Three-Wheeled Steam Freight Cart

Within a few days, merchants from Chang'an and Luoyang shipped their goods to Cangzhou.

Because the news that Cangzhou will build more warehouses has been made public, businessmen are unwilling to miss the business opportunities of dock warehouses. They all invest in Cangzhou when Cangzhou is developing. They can rent or buy mansions to stockpile goods later. Therefore, holding a pier is equivalent to holding wealth.

In the next few days, the Ministry of Economic Development will announce the shipping tax and fee, but the implementation date is written after the preparation of the new terminal is officially implemented. The maintenance of the Cangzhou has been completed and cargo transportation is being carried out in several coastal states near Cangzhou.

Satisfaction is a brand-new ship. If you want to sail, you need to find a good crew first. Cangzhou Shipyard will not be responsible for this part, and it needs to be handled by the Building Materials Chamber of Commerce.

The notice still uses the [-]-mile express official road race. It takes a few days to reach Cangzhou, and the time to Suzhou, Hangzhou, and Fuzhou is even longer. It takes a month to go back and forth.

So Yuanshan decided to speed up the application of steam power, and the customized boiler sent by Song Kangde to Yuan's family just met the conditions.

In the Yuanjia workshop, Yang Wu finally had a place to play.

"Master Hou, this is a wooden tricycle frame made by the workshop according to your drawings." Yang Wudao.

Yuan Shan looked carefully at the top, which is almost a flat plate and the three wheels form a triangle. The wooden wheel is about one meter in diameter. The chassis of the car is very high and the wheels are very wide, at least about [-] centimeters. The inside is the wooden wheel and the outside is thick. Iron, there are bearings inside the wheel.

One side of the single wheel is prepared to hang a small steam boiler, and the cylinder directly acts on the single wheel to play the role of traction.

"Master Hou, can this car really work?" Yang Wudao.

He didn't have any confidence at all. Usually the steam cars of the Yuan family were made of iron four-wheelers, but now he had no idea about changing them to wooden three-wheelers.

"Can it work? Remove it and install the small steam engine." Yuan Shan said.

Yang Wu signaled the workers to start working. Yang Wu was also surprised because this time the steam engine was very strange. The boiler felt like a big pot, but it could not be that the pot was deeper and the lid was higher.

However, the vertical cylinder is indeed relatively cheap, and its shape is very strange compared with the previous steam engine.

Half an hour later, the assembly of the vehicle was completed, Yuan Shan said: "It looks very good, go to the boiler to add coal and light it."

Yang Wu immediately followed suit, looking at the cauldron-like boiler with a coal bunker under it, and a lid on it for storing water.

The most special thing about this customized boiler is that it uses a double-exhaust cylinder and two cylinders act on the single wheel at the same time.

The combustion temperature of the coal rises quickly, and soon the boiler has water vapor.

Yuan Shan personally sat down and operated the control lever to close the valve, and the cylinder began to expand and contract slowly.

"It's moving, Master Hou, be careful." Yang Wu shouted.

Immediately there was a display on the pressure gauge, and the speed began to rise to five, and the slow movement began. With the coal burning, the value of the pressure gauge began to rise gradually, and the speed of the tricycle also increased.

"Haha, it worked. It seems that we can use this to carry out short-distance cargo transportation in the future." Yuan Shan said excitedly.

He can feel that although the speed is very slow, the cylinder driven by the steam is very powerful, and the steering of the tricycle is relatively easy after turning. If it is not enough, he decided to add a set of speed change wheels to this simple steering to better control its steering. flexibility.

After a round in Yuanjia Workshop, the stability of the rear three wheels is very good, but the relatively long body has a lot of steam, which affects the driver's sight, and the biggest disadvantage is that the driving speed is relatively slow.

There are also many advantages, for example, it will be easy to maintain, and the cost of the car body made of wood is low.

"Yang Wu will leave it to you to test the load of this steam truck." Yuan Shan said.

Yang Wu is no stranger to steam cars, and he always feels a little anxious to operate this slow steam car, but the load is comparable to that of a horse-drawn carriage.

This is too much for Yuan Shangen to look for a steam car to shoot, but the car at that time used the focus to push the wheels to move, but this car directly used the single wheel as a flywheel, which was completely integrated, similar to the wheels of a train , so that the tricycle can be more powerful.

Although the boiler is small, the steam released by encryption and thickening is more powerful, and a blower cylinder is added inside to speed up the burning speed of coal, which means that it can quickly release a large amount of heat energy.

Looking at the cost of construction, the cost is basically that the investment in boilers and cylinders is large, but the tricycle frame is worthless, and the production speed is faster.

After testing, Yang Wu obtained the final data. The load capacity is comparable to that of the train of thought, so it is no problem to pull a thousand catties.

A few days later, the horse-drawn carriages in the centralized warehouse began to decrease, because a lot of steam tricycles had been added.

The appearance of the steam wooden tricycle has attracted many onlookers, but people can only watch from a distance. The key point of the warehouse is that without transportation, people will not approach easily.

Bursts of steam permeated around the warehouse, and Yuan Shan felt helpless when he saw it. Right now, he can only develop to this extent. If he wants to go further, he can only increase cylinders or develop internal combustion engines.

The conditions for the internal combustion engine are already in place. Petroleum is used to extract gasoline and then burned instead of coal to produce water vapor inside, but this is only a preliminary heat energy substitution.

It is very difficult to invent a real internal combustion engine, otherwise there will be no progress for decades, and the engine is still someone else's.

Yang Wu and other craftsmen worked very fast and put together [-] steam tricycles in a few days. In order to prevent the steam in the centralized warehouse from being too dense, ten steam cars were turned into scooter. Although it is slow, it is better than walking. strength.

It's a pity that few people are willing to ride, because the speed is too slow and there is no difference from walking, and sitting on a tricycle will bump.

Through the success of the small steam engine, Yuan Shan felt that the boiler could be reduced several times and then used on a bicycle. For example, a four-wheeled bicycle could be faster due to the speed of the body.

When he came out of the Yuanjia workshop, Yuanshan's body was a little damp from the steam. Although the steam power is very labor-saving and the distance is far from the ultimate, Yuanshan thought of Li Chunfeng. This guy is very obsessed with objects. It is too wasteful to build a physical astronomical telescope. It is better to let him participate in the research on steam power, which may lead to a major breakthrough.

For the past few days, Yuan Shan has been living in Yuanjia Manor to study steam power. The complexity of the cylinder is often blind to him. He can only wait for further breakthroughs from the craftsmen. Next, a separate fixed structure is finally adopted.

The advantage is that the boiler is placed outside the processed room to avoid the pollution of coal smoke and dust. It is all about changing the soup but not the medicine, but it is finally feasible.

There was still no progress in the application of steam power. He realized that the development of the steam age might be over at this point. He suddenly thought of Li Chunfeng, who was obsessed with Gephysics, and wanted him to come and have a try.

Li Chunfeng is preparing lessons now, but he doesn't know that Yuan Shan, who is in Yuanjia Manor, is playing with him.

Chapter 664

While Yuan Shan was studying how to improve steam power, some noble children became interested in Fusang girls after participating in the sports meeting.

The cause of the incident was that during the performance at the sports meeting, Fusang girls wore traditional costumes and danced a group dance in front of tens of thousands of people.

The popularity instantly overwhelmed the dancing girls in Chunmanyuan, and as a result, the noble young masters followed her.

If he hadn't known that these people belonged to the Yuan family, he might have moved a long time ago.

It's just that the noble young masters often harassed the cleaning girls in the Lantian Economic Development Zone.

When encountering this kind of thing, the female workers dare not speak out and can only endure it.

But how could it be possible to hide the fact that the Lantian Economic Development Zone was owned by Yuan's family.

Especially the students in the talent school are guys with a sense of justice.
