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

"Try it?" Captain Qian asked suspiciously.

Zhou Lei and the project manager instructed him to do a rescue demonstration.

At this time, the engineers stopped all the work at hand and sat on the console next to them.

The big screen began to show some of the situation inside the sunken ship at the bottom of the pool, and a lot of high-definition underwater cameras were made.

Sure enough, I saw a few plastic people floating on the water in the half warehouse.

"Drop the life support." The engineers threw five life support into the water.

"Turn on the automatic search and rescue program." After the life support device received the order, the vector water jets began to work, and the highly sensitive visual system and small sonar allowed them to immediately discover the sunken ship on the seabed.

Then began to look for a way to enter the cabin. The life support was like a flexible sea fish, rolling up and down and shuttling. One of them found an entrance from the bottom, and the other four turned their directions one after another and entered from the bottom of the warehouse.

"You still have a data link." Captain Qian saw at a glance that there was still communication data exchange between the life support devices.

From several sub-screens, after seeing that these life support devices entered the cabin, they began to spread out, looking for each open cabin. There is almost no repeated search, which makes the onlookers feel amazing.

Ten minutes later, the life support devices arrived in the manned cabins one after another.

The sealed cabin in the front section was cracked, and a pack of oxygen masks was connected to a small oxygen cylinder, which was dragged by an orange fluorescent buoy and floated on the water.

"Okay, the test is complete. Thank you everyone." Zhou Lei clapped his hands.

Captain Qian held his chin in thought for a while, and said, "Do you sell your life support equipment?"

"Captain Qian, we are still testing and we have no plans for the time being."

"Old Qian, let's go." Mr. Chen took Captain Qian away, and he explained later.

After the coast guard ship and the helicopter were gone, Zhou Lei told the engineers a few words to let them change the submarine's paint to a bright orange-red color, so as not to happen again today.

Mr. Chen called and said that he wanted the method of color matching of polymer materials, and then said that the navy needed to buy some life support equipment.

Zhou Lei quoted them a cost price. This project itself is not for making money, let alone making money from the army. But it's not cheap. The cost of the life support device itself is more than 2,000 yuan. This does not include the price of the life support products inside. The main reason is that the vector sprinkler is too precise.

Taking into account the ongoing revision of the product, the final delivery time was delayed to three months later. The navy bought 10,000 units in one go and spread them over so many large and small ships, just like sprinkling seasonings.

The satellites that fly overhead every day suddenly find that many shipyards along the coast have suddenly disappeared from the warships that had been built and half-stopped. Their intelligence department also deliberately bought some shipyard personnel, which are said to have been dismantled.

It's time to give Hua Yuan a big thumbs up, such a prodigal behavior made some small countries around him breathe a sigh of relief, and they didn't seem to be so aggressive.

Some warships on normal duty have also been recalled one after another, and the anti-rust paint on the outer surface of the hull has been shoveled off, because some previous marine life will adhere to the surface of the hull below the waterline. When more and more, you need to drive back, park on the freshwater slipway, and rely on freshwater to kill marine life.

Now there is a very simple and effective way to directly spray the polymer material on it, which can ensure that the warship can continue to be on duty for a long time. Moreover, the study found that the use of polymer materials can increase the speed by about 1 knot, and at least 20% of the fuel can be saved.

This number is inconspicuous, but it can be extended at a critical time. What's more, 20% fuel is not an astronomical amount for gas turbines like gas hogs.

Therefore, the navy in Huayuan has been very lively recently. It is dismantling ships and repainting. Some surrounding countries are puzzled. What are they going to do? As long as there are no new ships on the slipway, it will be a happy day.

The happy days always passed quickly, and more new ships were added to the slipways of the major shipyards along the coast. Ships vary in size, and it was even discovered that the aircraft carrier code-named 06 has begun to be built in sections.

According to some iron filings stolen by the intelligence department, Citi’s laboratory analyzed and found that this is a brand-new marine steel, which is better than the steel on its own aircraft carrier and has nearly double the yield.

This is not bad. Of course, Citigroup doesn't think that Huayuan has the ability to research it by himself. Their first reaction was that it was an internal leak again.

President Maize immediately ordered all laboratories across the country, whether private or national, to be stationed in FBI personnel. For a while, the internal review was full of uproar. After years of smearing, almost no Asians can stay in these core laboratories.

Such a strict review did not find Huayuan's spy, but accidentally injured the friendly army. A lot of spies are traditional allies of Citi.

So he was made fun of by his own people, and the president with cornrow hair still made a lot of nonsense on social media, saying that the spies of Huagaki were hidden too deeply, and Citi would continue to look for them.

The rescue project is still going on, there is enough steel for testing, plus samples regardless of cost. The drawings were constantly revised, and a large amount of waste materials were pulled back to the steel plant for reheating.

The rescue drone that was first completed and then sent for testing has been working continuously for more than tens of days. There are some small problems, but they can't tell the big ones.

The main problem is that this kind of rescue technology based on the development of security drones

The load of the rescue helicopter is too small, and the load of several kilograms is useless in some rescue situations. But in terms of search, no one thinks it can't be done, it is simply better than imagined, as long as it is a living person, infrared signals can be found a few kilometers away.

Therefore, a drone with a large load and high intelligence is what the rescue really needs. Another solution of an unmanned helicopter has entered Zhou Lei's field of vision.

In fact, the technology that helicopters need to solve far exceeds that of military robots. At least now, for the ability of Sanshi Technology, the hinge of the helicopter is a big question.

Zhou Lei picked up the matter of military robots again, and he decided to continue to study the delivery system of military robots.

It's like a certain fat man. Their transport vehicles can hardly get out of the peninsula, so even if he has a big iron egg, no one is afraid of him, but his neighbors are scared to death.

If there is an unmanned helicopter with high load capacity and enough range, it can completely replace the current straight series of helicopters.

After Zhou Lei persuaded the big hacker about the blueprint, he reluctantly agreed. What he meant was that it was too simple to do. Zhou Lei was suggested to consider a large aerospace plane, which frightened Zhou Lei.

Aerospace planes can basically take off from the runway and fly directly into space.

Almost the few countries that are capable of research and development are still honestly climbing the technology tree. You said that a small company has made such a great product, will it be forced to buy it?

Therefore, a tilt-rotor aircraft similar to the dual-rotor Osprey is the most suitable product at present, and it took many years for Citi to finalize it. Over the years, they have fallen a lot, and many soldiers died before they were ready to fight.

But it is not the best time to release the drawings, because the main beam alone needs 10,000 tons of hydraulic press to forge.

Hehe, unless you build it yourself, and you want to ask which factory to help you, queue up, it is estimated that you may not be able to get it in five or ten years.

So Zhou Lei thinks, first get a 1:4 scaled down version of the Black Hawk unmanned helicopter. The smaller the volume, the smaller the size that needs to be machined.

The key to the helicopter lies in several major components, such as the engine, hinge, propeller and control system. As the most powerful and envied father of Ark Battery, of course, he has to use a DC motor.

The advantage is that the sound is quiet, the structure is simple, and only two parallel DC motors and a gearbox can be done.

For the military, jumping directly from a fuel-fired helicopter to an electric helicopter has many problems to solve.

The control system is relatively easy to handle, and an original version of the code has been given, and the laboratory staff have been called to start working on it.

The rest is machining work, with more than tens of thousands of large and small parts disassembled.

"Mr. Zhou, the surface of the propeller is too complicated, and the CNC masters can't handle it. You have to find another way." Wang Cong called Zhou Lei. He knew that Zhou Lei was busy with this matter recently.

"Is it a programming problem or a machine tool accuracy problem?"

"The accuracy is not enough, it is an order of magnitude worse."

"This is the best CNC lathe we can buy in China."

"You may need to find that Mr. Chen. It is estimated that he can solve this problem. We have already scrapped three propeller blanks."

"Okay, don't move the rest, I'll make a call."

Sometimes Zhou Lei didn't want to deal with Mr. Chen at all, and tried his best to pick things out of the country's pockets. It is conceivable that after his own life, he would come to the door again.

As soon as I remembered Mr. Chen, he called.

"Aha, President Zhou, hello hello."

"Well, it's not very good."

"Uh!" Mr. Chen felt that this was out of the way, "Is there anything I can help you with?"

"Yes, help me make some parts."

"Send the drawings to my mailbox, and I'll take a look first. By the way, there are departments that want to cooperate with you."

"I said first, I don't do the arms business."

"Take it down, I'm not willing to do it if you want to. This arms business is the most profitable, and it won't be cheap for you. We have a department to study an unmanned submarine, because considering that you already have a ready-made one, so and You work together."

"You want to be so small?" Zhou Lei always felt that there was something strange in it, maybe it was for the smart subprogram.

"That won't work. We're going to directly transform a diesel-electric submarine into an unmanned submarine for testing purposes."

"I'll borrow up to five engineers here for you, and I don't care about the rest, but poaching is not allowed."

"No problem, no problem." Mr. Chen agreed. "Why did you run to play with the helicopter again? If I read it correctly, this should be the propeller of the helicopter."

"Yes, unmanned small helicopter, just wait for the propeller, do you want to know?"
