One Planet for Everyone! Building Science and Technology Civilization at the Beginning

"I said, Mr. Zhou, you can't produce new products every three days. You've almost taken all the funds I have on hand."

"I'm also very helpless. This helicopter is also life-saving. Do you know that the rescue helicopter will never be used for military use."

"Hey, just say it outside."

"Mr. Chen, hurry up and bring the propeller to me, I'll wait for it." Zhou Lei didn't bother to talk to this chicken thief.

"Three days, it will be delivered to your factory in three days."

"When you see the propeller, you can find someone to sign the loan contract. Remember, you are not allowed to poach people."

"No digging, absolutely no digging." Mr. Chen complained about Zhou Lei's careful eyes.

A notification letter was sent to the shipyard, and eight of the system and automation control engineers were selected as candidates. Anyone who helps Mr. Chen can get double salary, and Mr. Chen will also give one.

This is troublesome, I think they are all short of money, and all eight people want to go.

Originally, I chose 5 out of 8, because I was afraid that some people would not want to go. What else can I do now? Draw lots. It's a simple matter, and God decides whether to go or not.

The propeller wrapped in oiled paper is definitely not inferior to the processing technology of the Germans. It seems that there are also very powerful masters and high-precision CNCs in state-owned enterprises. It must be the wrong way.

After testing, it fully meets the requirements.

Here, Mr. Chen came to the office and signed a staff loan contract for one year. Zhou Lei didn't ask him for any money, but just asked him to pay these engineers another salary.

He stuffed the U disk with the smart applet on the table back into his drawer, Zhou Lei just wanted to play with Mr. Chen like this. It is estimated that as soon as the engineers ran over, he knew he was wrong.

It's not that the engineers are very good, but the intelligent subroutines are very good. These engineers are only good at using software interfaces.

The unmanned helicopter has almost been assembled in the factory. Because there is no one, there are almost no things in it to maintain the safety of the personnel. It is just a frame with some batteries plugged at the bottom and some instruments on it, not even the skin. .

It can be said that the old Maozi said that as long as the engine is strong enough, the bricks can fly.

That's the case now, powerful enough DC motors to make this pile of shoddy iron frames fly in a second.

Fixed the helicopter's tripod, and then started the engine on the control platform, driven the gearbox, and the propeller fanned the hurricane in the factory building, blowing some unfixed things everywhere.

"Stop, stop, you guys hurry up and clean up. What a mess. Who is so smart to test the car directly in the factory."

Several engineers sneered and looked embarrassed. They couldn't take it.

"Put it down to test the machine." Zhou Lei waved his hand.

He pushed the wheeled counterweight truck, along with the helicopter, to the open space outside.

The counterweight on this car is several tons, all pressed by scrap iron blocks, which is difficult for these engineers who always love to make trouble.

"It's almost there, it's over here."

The other two took out the console for a test drive.

If there is a problem with the processing of the propeller, it will lead to the situation of chattering. The light one is very noisy, and the serious one will cause the body to be directly damaged.

Ugh... I still felt very loud when I got close. The wind blew away all the rubbish on the ground. For the first time, I found that there were still so many dirty things on the ground.

"Retract the throttle and switch the speed to standby mode." Zhou Lei wanted to see how the propeller worked in low-speed mode.

You can also pretend to be a fake expert, and after watching it for a long time, I didn't find anything unusual.

"Stop the car first and unfasten the bolts."

A few lively workers standing in the back went up with big wrenches and unscrewed the bolts in three or two strokes.

"Start to push slowly from the smallest throttle." Zhou Lei gave orders from the side.

"Got it, boss."

The propeller began to turn slowly again, and the reverse thruster at the tail also began to turn, preventing the helicopter from entering the circle mode.

"Slowly increase the throttle." For DC motors and gearboxes, it is to speed up the input of current and switch the gears of the gearbox.

It seems that the fuselage stabilization program has worked. With the cooperation of the rear thruster, the helicopter stays at a height of 30 cm from the platform, which is almost stable.

"Don't move, let the helicopter run steadily for ten minutes."

The hovering of the helicopter is a particularly important function, and in a real manned helicopter, this trick is too much a test of the pilot's skills.

But the program is much simpler to control, and the millisecond-level feedback makes the helicopter very stable.

"Switch to the intelligent test plan." This is a newly added function, mainly used to demonstrate the performance of the airframe, including various aerobatic maneuvers.

"Boss, do you want to test other functions first?"

"I believe that the program can correct any abnormal state, and now you can see how well it flies." Zhou Lei was still very optimistic about the helicopter, and went straight to the last step.

A menu option was selected on the console to enter test mode.

After receiving the order, the helicopter immediately accelerated the speed, and the propeller blew a strong wind. It soared into the air, flew into the air with its head held high, tens of meters in the air, began to hover at a low altitude, and then pulled it up to 500 meters in the air, performing various technical flights.

Because in this non-flight control area, you can fly in the airspace below 3,000 meters without the need to apply for it. This is only available in the past few years.

Then it flew over from a distance, passing through the field at a low altitude, blowing up a yellow dragon-like dust on the ground.

The computer here shows the real-time data of the helicopter from all aspects, and it also shows that it has not reached the maximum power designed, that is to say, it can fly higher, farther and faster.

The data curves from various sensors show that whether at low altitude or high altitude, the power system works normally and the control is very flexible.

"How much electricity is left?"

"There is still 56%, and it is expected to fly for two hours. However, we put a quarter of the battery in the battery slot, and it is out of stock. Boss, hurry up and send some batteries, it will not be easy to test later. ."

The boss is also very helpless. This kind of battery needs to be specially customized by the factory, so the few pieces you can get are just a few pieces.

"Next, you have to test the load to see the maximum static load and the maximum load under the high-speed flight that meets the design requirements, and several other items must also be paid attention to."

Back an hour ago, there was a domestic car parked near the gate of the factory with two men inside.

"It's too tiring to come here on duty every three days. What drink? Coke or Coke?"

"Don't you only have Coke? What else can you choose. But what can you do? According to the order from above, our day shifts are fine, but the night shifts are terrible."

"You said that this factory can not do things every day, but you said that which project has not been stolen, they are the most troublesome."

"You ask me, who do I ask? Well, didn't you see their boss' car in the morning, you went over and asked?"

"Hey, don't talk about it, I will be criticized again later."

The car rang, "Post No. 1 report the situation."

The man in the passenger seat picked up the handstand, "Report from Post No. 1, everything is normal in the factory area, and no abnormality was found at the door."

At this time, the helicopter whistled and flew overhead, startling the people inside.

"Post No. 1, what's the sound?"

"The main station, the main station, it's a helicopter."

"Continue on duty." The person in charge of the main station turned back and asked the police who knew the situation of the factory, "Do you have any news, they bought a helicopter?"

"No, I've never heard of it." A few policemen looked confused, what was the situation.

"Come on, let's go and have a look."

A group of people ran to a tall building next to it, and they could see it with the naked eye. I originally thought it was a model aircraft, but I didn't expect it to fly right in front of my eyes. When I pulled it up and flew over a high-rise building, I realized it was a big thing.

But it's really ugly. There is no skin, and the wiring and mechanical structure are all exposed.

"Look, you can even do stunts!"

At this time, the leader's cell phone rang, and he was happy when he saw the number.

"Mr. Zhou, hello, hello."

"Hey, Director Yu, how big of an official are you playing peeping. I said why there are a group of people peeking at the camera, so it's you."

"It's not the helicopter you got that alerted us."

"Come here and see, there is nothing to keep secret." Zhou Lei invited these people to visit the factory. After all, it is very hard for those policemen in plainclothes to help housekeeping every day.

The helicopter was still circling in the sky and preparing to land. The police entered the factory gate and ran to the site where the helicopter took off and landed just now.

Everyone shook hands and greeted each other, and they began to gather in front of the helicopter.

The height is close to 1.2 meters, and the length of the fuselage is 4 meters. Standing next to it, although it is a reduced version, it still looks very large.

"Mr. Zhou, your helicopter is pretty good. How much do you have to sell for one?"

"It's estimated to be in the millions, and it's not fully finished yet. Do you want one?"

"I can't be the master of this. The police equipment procurement is decided by the General Administration."

"I'm kidding you, this is for rescue, and other functions are still being developed."

"Hahaha." Director Yu patted Zhou Lei on the shoulder.

"However, if you need our help in the future, such as searching and other tasks, we can still do it manually."

"Then it's good to be brave, or your big company has the ability."

Invite them back to the office to drink tea and brag, then leave, not even daring to eat lunch.

The helicopter is basically finalized, and it is necessary to continue to add some batteries to achieve the designed battery life. Then there is how the industrial designer can match it with a suitable skin shell. Of course, it can be so naked, but it is too ugly and does not fit the corporate culture of the company with deep pockets.
