#1836 - A bold idea, a sustainable electric helicopter!

When Chang Yichang, Shunfeng and others followed Hutou to the North District Comprehensive Building.

He looked at the bustling crowd inside and stood there in a daze for a moment.

So many people!

There were at least hundreds of people in the hall, and the noisy hall made him feel as if he was in another world.

When he first entered the trading bazaar, he didn't see many people on the street.

I didn't expect there would be so many people inside.

"Young man, are these all here to apply for points-based loans?" Chang Yichang asked Hutou.

Tiger Head smiled and nodded: "Yes."

"There are too many people!" Shunfeng's eyes were full of surprise.

"Oh!"

Tiger Head twisted his wrist and said, "Today's number is still relatively small. A few days ago, the queue stretched one or two kilometers outside!"

"Let's go, get in line, I have to go back to my post later."

"Okay, okay, thank you." Chang Yichang thanked.

They are like villagers who have just come to the big city from the countryside and have not seen much of the world.

Everything in this trading market is so new and novel.

"What if someone bullies us? Can't we fight back?" Biaozi asked back.

When entering an unfamiliar environment, I always worry about being bullied by others.

So naturally they have this concern.

Tiger Head said in a deep voice: "If you fight back, both parties will violate the regulations and will be punished. But if you don't fight back, run away and ring the alarm, and let the patrol team handle it, you will not be responsible."

"What punishment?" Biaozi asked.

"Kill!" Hu Tou said this in a casual tone, as if he was talking about something very normal.

Biaozi and others looked at this young boy who looked still a bit immature, their eyes full of surprise and suspicion.

Hu Tou opened the manual from Chang Yichang's hand and said, "It's all clearly written here. Take a good look at it yourself. There are some classic cases on the last few pages of the manual. These are all real cases that happened."

"In short, if you behave yourself in the market, no one will bother you. Even if someone does, just tell the patrol team and they will handle it impartially."

"good."

Chang Yichang opened the last few pages of the manual. The text in the manual was concise, but the content was murderous.

[On XX, the Golden Tiger Gang carried out large-scale extortion near the trading market, killing people and seizing the goods of residents in the trading market. After the patrol team confirmed the incident, all 156 members of the Golden Tiger Gang were arrested and beheaded in the South Square. They were hung on the wooden stake to the right of the notice board as a warning to others.]

So cruel!

Chang Yichang deeply felt the meaning of the phrase "severe punishments should be used in the last days".

While waiting in line and chatting, Chang Yichang got to know more about the rules and regulations of the trading market.

Before they knew it, it was their turn.

Chang Yichang was quite humble when facing the staff.

When the staff saw their information, they were a little surprised. They were people who just came in?

This icy disaster has lasted for more than three months, and there are still new people coming in.

Hu Tou happened to know the staff inside and urged, "Liu Tao, hurry up and get it done. I'll take them to find out where to buy supplies later."

Liu Tao rolled his eyes and said, "I know, little brat."

"Hey? I'm not little anymore, okay?"

Liu Tao glanced at him and was harsh in his words, but his actions were quick.

"The little guy has grown up. Let me see him."

"You hooligan!" Hu Tou's face turned red.

After all, he is still a teenager and cannot withstand the verbal teasing of a woman in her thirties.

After completing the points loan application, Chang Yichang took the number card and followed Hu Tou to the commercial district to buy tortillas.

Hu Tou kindly gave a few reminders.

"Food is hard to come by now, so try to eat sparingly. You will have to pay back these points later."

"Thank you, bro."

Hu Tou then took them to the housing management office and arranged accommodation for them.

Since it is their first time here, they can enjoy free accommodation in the first week, but they will be charged a heating fee. However, the heating fee is relatively cheap now.

After taking them to Room 405, Building 56, Zone C, a residential building.

Hu Tou pointed to a few rooms nearby and said, "These rooms are all empty. You can allocate them among yourselves. There are eight people in each room. I have already taken you around."

"The place to get water is at the water station in the building in front. If you have any other questions, you can ask the neighbors next door. I have something else to do and I'm leaving first."

After saying that, Hu Tou walked downstairs with his gun.

"Wait." Chang Yichang suddenly called Hutou.

Hu Tou turned his head and looked at him in confusion: "?"

"Thanks."

Hu Tou raised the corner of his mouth, nodded, and left the residential building.

Chang Yichang took the number card in his hand and pushed open the door of the room.

The heating is on inside and it's as warm as spring.

The tortilla in his hand made him feel unreal.

Trembling, he walked to the edge of the bed, took the tortilla from him, and asked Chang Yichang, "Brother, we are all very hungry, how about eating something first?"

"One quarter per person." Chang Yichang said after hesitating for a moment.

This amount was already a luxury for them before.

"Long live the boss!"

"Brother, it's so warm in here. I can finally have a good sleep."

"Brother, can we stay in the trading market forever? It's like heaven in here!"

Heaven?

Chang Yichang thought about the repayment rules for the point loan and began to wonder how he could earn points in the trading market.

Half a month passed in a flash.

In a blink of an eye, the ice disaster has lasted for 4 months, 120 days.

The outdoor temperature gradually rose to minus 48 degrees Celsius.

It’s still cold, but it’s much better than the previous lowest temperature of over 80 degrees below zero.

Cat winter.

During this period, the Dazhangshu Headquarters Base, Oil City, and the Northern Territory all tried to stay in the base and not go out anywhere.

Except for the last time when the Judge and others went out to search for meteorites from outer space in Palau, the people from the Big Camphor Tree faction have not gone out anywhere.

With a temperature of minus 48 degrees Celsius, helicopters and drones can already fly.

Originally, when the temperature was more than 50 degrees below zero, some armed helicopters were able to take off, but there were no missions at this stage, so they did not go out.

Over the past half month, Judge and his men have been staying at the headquarters base to help perfect the plan for operations in the northwest.

The first outer city.

Administrative building.

Sandbox indoors.

The judge pointed to the sand table of the northwest base and said:

"City Lord, it's too far from the headquarters base to the northwest base."

"We must set up a transfer station to stockpile ammunition and troops. We can do this by first storing the troops and ammunition of the headquarters base in Oil City. This will be the first transfer station. Then, after taking Wuyuan Mountain, we will set up the second transfer station in Lan City."

"Lan City has a critical geographical location, strangling the throat of the northwest."

Li Yu stared at Lan Shi, frowned and said:

"It's possible, but we have to lure the zombie tide over first. My core idea is to take over the northwest at the lowest cost. We have zombie attracting potions and zombie sonic weapons. We can use the zombies. We don't want our brothers to risk their lives to fight them head-on."

"Our ideas don't conflict. I just suggest setting up a transfer station so that it will be more convenient for personnel to rest and be deployed." The judge explained.

"Yeah, I have no problem with that."

After coming out of the administrative building, Li Yu did not put on a helmet, nor did he take a car. He walked towards the second outer city.

The latest novel is published first on Liu9shuba!

The wind outside is dry and cold.

Just now, the sandbox room was filled with smoke and fog.

Li Yu has quit smoking for a long time.

Coming out of the sandbox room, he, who was originally a little dizzy, instantly became much more sober.

Recently, He Bing came up with an extremely bold idea, which made him very interested, so he would go to the machinery maintenance factory from time to time recently.

He came up with a concept for an electric helicopter.

Before the end of the world, there were actually electric helicopters, but at that time electric cars were still under development, and electric helicopters had just moved from concept to practice, and were still in their early stages.

It has not yet been widely used and has not even been used in specific scenarios.

However, during the last seven years of the last days, people from the Ministry of Science and Technology solved a difficult problem.

Solid-state battery technology.

It was finally developed at the end of last year and achieved small-scale mass production.

The energy density per unit area of ​​solid-state batteries is five times that of lithium iron phosphate batteries.

For example, before the end of the world, electric vehicles became more and more popular, but at that time electric vehicles mainly used lithium batteries or lithium iron phosphate batteries.

The core reason why it failed to replace traditional fuel vehicles in the market before the end of the world is the range anxiety issue.

The range of electric vehicles is generally 500 kilometers. After a 60% to 70% discount, it is only 300 to 400 kilometers. Moreover, the charging speed is relatively slow, taking half an hour or an hour.

It only takes five minutes to refuel a fuel car, the charging speed is too slow.

If this type of solid-state battery becomes popular before the end of the world, the range of electric vehicles can reach 1,000 kilometers. If the charging problem is also solved, fuel vehicles will be eliminated from history.

And now.

The Dazhangshu base has realized solid-state batteries and overcome the problem of charging speed.

Now a small electric scooter in the base can have a range of up to 150 kilometers. This is the advantage of installing solid-state batteries, which have extremely high energy density per unit area.

The most important thing is that they found the real green and pollution-free energy, zombie power generation!

In recent years, they have developed a sustainable version of the RV, with zombie generators installed on the bottom floor to generate electricity.

It is possible that a car will never need to be charged.

After solid-state batteries came out, the space occupied by the batteries became smaller, freeing up more space to install zombie generators.

So He Bing thought, since the zombie generator can be installed on a car, can it be installed on a helicopter?

That way, the helicopter can keep flying!

There is absolutely no range anxiety issue.

Since helicopters need to take off, the armor plates cannot be made too thick, otherwise they will not be able to fly.

It is different from those armored RVs on land, and there are more factors to take into consideration.

In this apocalypse with constant natural disasters, helicopters are a very good means of transportation, because many roads are destroyed, and there will be various accidents on the road, including encountering enemies such as zombies and thugs.

Helicopters are different and completely ignore the zombies.

But the only drawback of helicopters at present is that their flight time is too short.

Although they had thought of various ways before, such as adding auxiliary fuel tanks and even modifying the cabin to add fuel tanks, in order to reduce the number of people on board.

But it has reached its limit. Currently, the maximum range of the helicopter at the Dazhangshu base is only 3,000 kilometers.

No more fuel, so we have to land.

It is also impossible to refuel because the vehicle cannot keep up with the speed of the helicopter. The helicopter cabin is equipped with fuel tanks. If the fuel tanks in the cabin are used up, how can it fly?

The reason why Li Yu was so excited was that if the zombie generator could be installed in a helicopter, a sustainable electric helicopter could be successfully manufactured.

Then it will become extremely easy to get rid of the Northwest Base in the future.

Now, to go to the Northwest Base, the helicopter with the longest range can reach the base one way, but it must land after arriving, and to land it is necessary to find fuel.

Or they send a vehicle to transport the fuel in advance, and then the helicopter finds the fuel and refuels after landing.

But there are too many possibilities in the middle. What if we are discovered by the Northwest Base while refueling? Or what if we are surrounded by a group of zombies?

The group of zombies were hanging on the helicopter, but the helicopter was too heavy to take off, so they could only wait to die.

In addition, with a sustainable electric helicopter, it would be easy for them to travel to Palau.

There is no need to send a behemoth to drive back and forth for half a month as before.

30 kilometers per hour.

If we take a helicopter, it will arrive in more than ten hours at a speed of 300 kilometers per hour.

That would be much simpler.

Moreover, electric helicopters have an advantage: they make little noise.

It is very suitable for use in the end times and is not easy to attract zombies.

In short, once the sustainable version of the electric helicopter comes out, the strength of the Dazhangshu base will be taken to a new level.

Tap tap tap——

Li Yu was enjoying the wonderful things in his mind and before he knew it he had arrived at the machinery maintenance factory.

The machinery maintenance factory covers a large area, and the machinery research institute is also located inside it.

There are more than 200 people working there now.

Half of them are maintenance technicians, and the other half are all scientific and technological researchers.

Power research, motor research, mechanical engineering control, automation, aerospace, and intelligent manufacturing.

There are relatively few researchers in some categories, but at least in terms of subdivided fields, the Dazhangshu base is becoming more and more comprehensive.

The Dazhangshu Base is also currently recruiting various scientific research talents.

The last wave of people transferred from the Oil City to the headquarters base included some laborers, as well as hundreds of top students involved in daily chemicals, engineering, machinery and other fields.

Li Yu walked into the machinery maintenance factory.

The factory has high ceilings, and a medium-sized armed helicopter is parked in the center.

The rotors above have been removed.

Before Li Yu walked over, he heard Lao Zhou's voice coming from the other side.

“As for the rotor part, I still reserve my opinion and adopt a multi-rotor redundant design!

Equipped with 18 electric rotors, it can significantly improve safety, so that even if some motors or batteries fail, it can still fly stably. "

"A helicopter is not like a car on land. Once the motor fails and it cannot fly, it will be doomed if it stops. Therefore, even if it is necessary to have more rotors to increase the load, it is still necessary."

(Please give me a monthly ticket, I will speed up the pace and click on the technology tree~~)
