Rising: Ten Thousand Years Chapter 490: : get angry
The brake problem of the train is a very difficult thing to deal with.
It is too heavy and has too much inertia to stop like a car.
The technician found that there was a problem with the brakes, but there was no way to fix the problem. Li Zhen also knew that the braking effect by hugging the wheels can only be moderate, but not perfect. But he didn't have a better way to deal with it either.
The only option is to lock the wheels.
"Master Li, do you want to redesign the wheel?"
"No need."
"I think the friction force of the wheels should be increased. The friction force between the steel wheels and the rails is too small. After the wheels are locked, it will still drive forward. Does this mean that the train will drive to 8 At ten miles, the brakes even have to be completed several kilometers in advance?"
Li Zhen hesitated for a moment: "If nothing unexpected happens, that's it."
"What should I do if there is an emergency? What if someone suddenly breaks into the train tracks?"
Li Zhen said: "Actually, you have overlooked a problem. The brakes of the train should not be done by the front of the train. A string of carriages should be hung behind the train. The braking effect of the front is not good, so all the carriages, hundreds of steel All the wheels are locked and the brakes are locked? You have misunderstood this concept. You always think that the brakes of a train depend on the front of the train. This is unscientific. How can a front of a train resist such a strong inertial force?"
Everyone suddenly realized.
"Oh, that's it. :"
"Based on this, if all 20 carriages are locked to the wheels, then nearly a hundred wheels are all locked. In this way, the friction force will be doubled."
"But, is there any other way?"
Li Zhen shook his head: "No."
"But what should we do if there is an emergency? Can we just helplessly crash into it? If the train hits something, it is too dangerous. The front of the train hits first, and the inertia of the dozens of carriages behind is amazing? If they all rush to the front of the train, the people in the front of the train will definitely not survive. Maybe the train will derail."
Li Zhen drew a few lines on the railway map: "So, the rails must not be exposed to the open air. Steel wire mesh should be pulled up on both sides of the rails to prevent wild animals and residents from intruding. Every once in a while Set up sentry boxes at a distance, check the steel rails regularly, and expel nearby wild animals. The steel wire mesh must be pulled up, and it must be strictly guarded against."
"Also, some train tracks have to pass through residential areas. Then checkpoints must be set up at the intersections, and trains are prohibited from passing. Use the sideways method to solve the problem of train braking. Only in this way is the best Good solution. There is no more perfect idea for train braking."
“…”
After Li Zhen finished speaking, he looked at the damaged locomotive pulled by the trailer in the distance: "The power is still a bit weak. First produce the regular locomotive, and then test it after the carriage is hung. Problem, this principle is no problem. Let's find a way to solve other problems after the finished product is produced in the factory."
"Yes, Master Li."
Li Zhen boarded the car with a smile: "Let's go to the airport, today is also the day to inspect the Peng style."
"Master Li, Director General Jiang is here soon, and he also wants to watch the Peng-style test flight."
"Who is Director General Jiang?"
"Jiang Tianqi, the former emperor of Beizhou, Jiang Tianqi. Now Jiang Tianqi is the head of the New Kyushu General Administration of Transportation. He is highly regarded by Du Taiping."
Li Zhen raised his eyebrows, thinking of this fellow.
I once met with myself, and let the 10,000-year consortium in my hand earn several tons of gold. Then he was placed under house arrest in Quancheng County. I didn't expect to become a party member now.
Smiled and got in the car: "Okay, wait for him. See what the old acquaintance looks like now."
"Let's go."
“…”
‘Dididi’
The head car honks its horn.
A convoy of more than a dozen vehicles from the Kyushu Academy of Sciences evacuated from Dafengtai Railway Station and headed for Dafengtai's airport.
The crowd did not disperse. After watching the train experiment, many people wanted to watch the Peng-style take-off.
Everyone is full of curiosity about the legendary large aircraft. If the Peng style is successful, it may usher in a new era.
An era that completely shortens the distance between the world. From now on, the transportation will be three kinds - sea, land and air.
"This train is purely tasteless. I heard that the brakes still have serious problems. They can't stop. The brakes all rely on collisions."
"Forget about the train, let's go to see the plane. The highlight is the Peng style."
"I heard that this Peng-style future is going to travel thousands of miles to meet the emperors of various countries. Let's go and have a look."
"It is said that the Peng style can seat thirty or forty people. It is also more stable than the Grasshopper, and it uses twin engines."
"If you don't understand, don't talk nonsense. The Peng type is a variant of the Grasshopper. Its scientific name is a transport aircraft."
"How great would it be if we opened airports everywhere in New Kyushu? If there are Peng-styles all over the sky, then New Kyushu will be completely developed. You don't need to take a car for a few weeks to go anywhere. You can get on the plane in a while. Arrived."
“…”
Go to the airport. There are already a sea of people here.
Naturally, the Kyushu Academy of Sciences has its own pergola, which is simple but heavily guarded. There are all important people inside, and it is also the place with the best view.
When Li Zhen arrived, the Peng-type plane had already arrived and was wrapped in a huge canvas. Just waiting for Li Zhen's order to start taking off at any time.
"Mr. Li, do you want to warm up the engine now?"
Li Zhen looked at his watch, it was already three o'clock in the afternoon, and the sky is high and the clouds are light at this moment, which is the best time for vision. No harsh midday glare, no heavy afternoon clouds.
"Wait."
Looking back, Li Zhen said again: "Send a telegram to IndoMTL.com to see where General Jiang is?"
Liu Jinghong shrugged his shoulders, with a somewhat disdainful expression: "Mr. Li, why wait for such a small character. Why should the Kyushu Academy of Sciences care about the Kyushu Party? There is no need to wait for him, just to lower their status. Let's test fly our Just fine."
Li Zhen said with a smile: "We have to wait."
"Why wait?"
"The Peng style is only developed, and the government has the final say on whether it will be produced or not."
"The Kyushu Academy of Sciences has the final say."
Li Zhen frowned: "The Kyushu Academy of Sciences doesn't have the energy to go into mass production. Shouldn't the Academy of Aeronautics focus on development? Designing an airplane is an art, so what if you keep thinking about standing still on the same work?" What's going on?"
Liu Jinghong opened his mouth, but was speechless. After a while, he sneered and said, "That's right."
The people around were also shivering. Although Li Zhen's tone was calm, everyone felt that Master Li was angry.
What are you angry about?
I got angry because of the aviation academy's idea of standing still.
Or is he angry because of Liu Jinghong's dismissive attitude towards the government?
Neither.
Li Zhen was only angry because of the mentality that is now common in the Kyushu Academy of Sciences.
They didn't feel it themselves, but Li Zhen felt it. Most of these people are a little swollen now, and it is difficult to keep that normal heart...
If this kind of common sense of being a human being is missing. It's dangerous for them.
