It was raining heavily at the end of July. Dalu was still stranded in Funing County.

For this reason, Lu Huiqing jumped anxiously because objectively speaking, no one actually hoped to be "helped on the horse and sent a journey" by the old leader, which would reduce Lu Huiqing's sense of existence and live in the shadow of the leader.

The rule of the Great Song Dynasty was of course in the hands of Lu Huiqing. But the reality is so strange. Once the Great Demon King stayed here, no one listened to Lu Huiqing, and Lu Huiqing himself dared not ignore it. This is politics and the real halo of leader.

Since that darkest moment came, the dark clouds were covered with military, political, military morale, and so on. Once again, the scene was shocked by the invitation of the idle devil king to command and command. After winning the bandit suppression war, Wang Yun's prestige, among the people, and among the border people, had reached its peak and the high position of the altar.

Damn it’s the folk who fooled themselves. With the cooperation of various street stall literature, the voice of the Great Devil is really not a joke.

The great devil cannot be driven away from the law and technology. Wang Yun's sick leave note was made up by Lu Huiqing himself. With his precise literary talent, the Zhongshu did not deny it, which means that there is no problem for Wang Yun to continue to write here.

It was raining all the time, and a group of big-headed soldiers held umbrellas. Wang Yun rushed to the machinery factory accompanied by Lu Huiqing and the main leaders of the county government.

In addition, the editor-in-chief of the Industrial Development News personally participated in the report, because today is a memorable day. Without affecting the original steam engine production capacity, today is the day for the first test run of the second generation of new steam engines.

This plan was set tone during the war and was carried out simultaneously in public relations.

In the assembly workshop, the design structure is completely different from the previous generation steam engine. It is much smaller and is placed in the center of the test site. Relevant technicians are doing the final inspection and finishing work.

Overall, this thing is still stupid, big, black and thick, but it has been greatly improved compared to the previous generation. Wang Rong and Lu Huiqing walked closer and looked carefully. Although they didn't know what the inside looked like, the surface was much cleaner and refreshing than before, and the matching and combination of many parts was much smoother. This represents a better coordination of the entire unit.

This is the advancement of craftsmanship.

Lao Luo, the chief designer of the second-generation machine, walked out and reached out to touch the machine and said: "Mr. Xiao Wang, in addition to the progress in technology, there have been breakthroughs in materials over the past period of time, so the appearance cannot be seen. However, inside, I am proud of the progress in technology and the renewal of materials, and the integrally formed parts are more, and the strength and fatigue resistance are greater. Therefore, according to the design requirements of the safe solution, the horsepower of this machine will not be much improved, but the service life will definitely be greatly improved."

"In the past, the steam engines sold by our factory were more frequent and difficult to provide warranty and maintenance. We can expect that this generation of steam engines will be of better quality after sale, and the after-sales maintenance pressure of our factory will be reduced, which will lead to a decrease in costs." Lao Luo's father concluded.

Wang Rong didn't say anything, Erya and Xiao Lingdang bit their fingers and looked at the machine curiously.

Lu Huiqing responded to his favor: "It's still not stingy enough. Last night, our county looked at the design process and technical indicators of the second-generation machine overnight, and only reached a 47 horsepower, which is several percentage points lower than the design requirement of 50 horsepower. The manufacturing cost is 10% lower according to the design requirements, but now it is only about five percentage points lower than the previous steam engine. Therefore, our county said that we will continue to pay attention to this matter and we still need to work hard."

He couldn't just tell Lao Lu about the stage, so Wang Rong refused to speak, saying that he agreed to Lu Huiqing's remarks. But in fact, he was very happy inside. The result was already very good. How could he meet the planning indicators very standard? It was really enough to achieve the slightest, and Wang Rong should have doubted what they were hiding.

Speaking of which, in a constant temperature workshop, there are errors in the things measured with a caliper, so how can the plan really meet the standards?

This is just the first machine, is a new architecture the beginning? There are many things to be mined. In the subsequent magic modifications, it is expected to dig this machine to more than 90 or 100 horsepower. If it really reaches 100 horsepower, then railway transportation will really become a feasible solution.

Otherwise, it will be so cold now. The first generation of steam engines is too stupid and thick, and it is very large and heavy, and the push-to-weight ratio is too low. Even if the magic modification reaches the end, it will only be about 60 horsepower. This sixty horsepower must be used in fixed occasions, such as mine conveyor belts, large city wall cranes, and water pumping systems are barely OK. Although the cost is high, it can stably output and release manpower.

However, it is unqualified to be used for locomotives. After repeated testing by Ye Wushuang's R&D base, even if the current train structure strength requirements are not high, it can be considered that in addition to the key parts, the weight will be very heavy. In addition, the thrust-weight ratio of the stupid and thick units is too low. Therefore, although the first-generation steam engine can also be used, Ye Wushuang's test data is: only one carriage can be brought, about five tons of materials can be planted, and a relatively economical speed of seven knots per hour is required. There are many people on the train. If you encounter an uneven area, as long as it exceeds a four-degree slope, someone will need to come down to participate in the push of the train.

It's so cold, with a load of five tons and a speed of about seven knots. Do you still need to prepare a strongman to participate in the cart?

In addition to being too low in efficiency, this also adds too much difficulty to the location and design of the railway. These are all a system that pulls each other.

But despite this, when the second-generation steam engine was not seen to be launched, Ye Wushuang still followed up on the development and testing of the train. There is only one reason: unless the existing transportation effect relies on the river channel, even the speed of seven knots is faster than that of the ox cart. Even if the load of five tons is loaded, it is more efficient than that of the traditional ox cart, and it can release manpower and cattle to a certain extent.

Now, although the design of the second-generation steam engine is a conservative solution, as long as the magic is modified to the end and the horsepower is greatly increased, it will reduce the volume and weight. This is a jump-like thrust-weight ratio. It can be equipped with two cars at a speed of fifteen knots to increase the load. The operating life of the unit will be longer.

When I think of these big fools, I feel so excited. It’s not that they are not vulgar enough. Is there any? I haven’t calculated it carefully yet, it’s just the improvement brought about by the steam engine improvement.

But in fact, it is impossible to just improve the steam engine. As the process and materials improve, the axle will become more efficient. As the design experience increases, the body weight decreases and the strength increases. As the core technology is slowly excavated, the conversion efficiency of the transmission system can also be greatly improved.

So these multiple bonuses were weighted and calculated. Now Wang Yun dared to make a wild statement. The transportation revolution will begin within three years. The fifteenth quarter will be a very reasonable speed, which is much faster than the horse gang that does not eat, drink, or sleep. If you climb up, unless the machine's thermal efficiency breaks through at a magnitude, it will be more than worth the loss, and the steps will be too big to pull the egg.

According to the principles of aerodynamics, starting from more than fifteen knots, a lot of power will be consumed by speed and will climb geometrically. If you reach a super high-speed rail with speed of hundreds of knots, 99% of the power will be used to overcome air resistance, and at most only two% of the power will be used to carry the load.
