Upgrade the world from Hongmeng system

Chapter 287
On September 2027, 9, while Wu Hao was handling official business in the office, Lu Ben knocked on the door of the office.

"Mr. Wu, the development of the graphene hydrogen gas bag has been completed, and this is a trial product."

Luben took out a thing that looked like a diving oxygen cylinder from the express box, and it was silver-white in appearance.

Wu Hao took the gas cylinder, examined it carefully, and found that the gas cylinder had not been filled with hydrogen at this time.

However, in terms of hand feel, this bottle is indeed very light. Because it looks like metal, Wu Hao was not used to holding it in his hand at first. When he swung it with excessive force, he almost hit the chandelier on the top.

"How much does it weigh?"

"Together with the metal valve on the top, 562 grams in total."

"How much does it weigh, minus the valve?"

"256 grams."

"Can it float when filled with hydrogen?"

"Uh... just sent it, I haven't tried it yet."

"Come on, let's try!"

The two came to the aircraft model studio, where there were several bottles of high-pressure hydrogen.

With Xu Longfei's help, the gas cylinder was filled with hydrogen, but it didn't float up, even though it was already light when picked up.

Weighed again, and the displayed weight was 82 grams. After all, the volume of the gas cylinder is not large, and the buoyancy it can provide is not much, but with such a result, Wu Hao is already very satisfied.

"Have you done the impact test?" Wu Hao asked.

"I just wanted to report this to you. Our existing equipment is unable to conduct a comprehensive physical test on this material. We need to send it to a professional testing agency for testing to know the true physical properties of this material."

Lu Ben quickly replied that he went to Wu Hao to talk about this matter.

"Well... put the hydrogen inside clean, and then hand over the things to me, and also bring a copy of our original technical specifications, and there will be a test report in two days."

Wu Hao thought of the graphene supercapacitor battery research and development base in a certain city in the northwest. Where there is a complete set of experimental equipment, Dabin can use the laboratory, and it is safer to ask him to help with the acceptance experiment.

"Ok!"

Reuben turned to work.

"Long Fei, how's the engine going?" Wu Hao casually asked about the work progress of the ducted shaftless engine.

"The thing is here, we are doing a low-speed test, and we can show its performance when it is fully debugged."

Xu Longfei brought Wu Hao to a long table, lifted a piece of black cloth, and a motor with a thick front and a thin rear appeared in front of him. The total length of the motor was more than one meter, and there were 8 fans in total. When using 220V power supply, The design thrust is 100 kg.

"Can you test it for me? It's fine at low speed!" Wu Hao was very curious.

"Yes." Xu Longfei seemed very confident.

After plugging in the power supply, it first enters the cloud self-inspection mode. This is the experience borrowed from cloud appliances, which saves many manual inspection items before starting up.

The fan inside began to rise slowly, and the voice prompts that a certain level of fan is in place, which feels a bit like futuristic technology.

"All the fans use the magnetic levitation technology, the noise is greatly reduced, the calorific value is also reduced a lot, and the maintainability of the engine is greatly enhanced." Xu Longfei began to introduce some basic features of the engine.

The fan kicks in, the low-speed test mode allows a maximum speed of 2000 rpm, and the engine makes a "buzzing..." sound, like an electric car humming on the road.

Wu Hao stood behind the engine and felt the wind pressure. Although it was only in low-speed mode, the thrust of the air compressed by the 8-stage fan could reach about 10 kilograms. It was very uncomfortable to be blown on the face by the wind.

"Yes, keep working hard and strive to complete the test as soon as possible. Before the graphene capacitor battery is mass-produced, I will make a prototype for flight testing."

Wu Hao gave Xu Longfei an order.

"Mr. Wu, when will the graphene capacitor battery be produced?" Xu Longfei was very curious.

Before, everyone in their group believed that Wu Hao's pre-research on such an engine was useless, but when the news that the single-layer graphene sheet manufacturing process was conquered was broadcast, their thoughts changed a lot, and they felt It is still possible that this engine will be used.

"It's still hard to say, but there is still hope for mass production. You must hurry up to get the engine ready, and at the same time prepare the car body with new materials. Once there is progress on the battery, we will start flight tests immediately. "

Wu Hao did not give a definite time. At this time, everything is hard to say, and he can only wait for news from a certain city in the northwest.

Lu Ben prepared the courier, Wu Hao gave an address, and he also notified Da Bin at the same time.

"Dabin, here is something that needs to be tested. I'll send it to you, and you can help me test it according to the items on the list."

"what?"

"Hydrogen balloon made of graphene film."

"What do you want this thing for?"

"I want to use this material to make an ultra-light car body."

"Well, your thoughts are really jumping!"

"Hehe, please!"

"..."

After arranging things well, Wu Hao continued to devote himself to the work of Haotian Technology. The two generals under him were not in the company, and the management pressure increased sharply. He was too busy to breathe.

……

Two days later, at around ten o'clock in the evening, Xiao Lang suddenly received a call from Kong Hao.

"Wu Hao, what's the matter with your airbag?" The tone on the other end of the phone was a bit harsh.

"Brother, I asked Da Bin to do a test. It's a private job. I didn't tell you. I'm sorry!" Wu Hao knew that he was wrong, so he quickly admitted his mistake.

"I didn't ask you about this, but I asked where did you get the material for the airbag?" Kong Hao's tone softened a bit, but he still seemed anxious.

"Zhang Li helped me contact a laboratory. This is a product they developed for me using graphene film..."

"Beep beep..."

Before he could finish speaking, Kong Hao hung up the phone, and dialed back, indicating that he was on the phone.

Wu Hao felt that something was wrong, so he quickly dialed Dabin's phone number.

"Da Bin, what's going on with Kong Hao?" Wu Hao anxiously wanted to know the situation.

"Don't worry, it's a good thing he's looking for you tonight, not a bad thing!" Da Bin quickly comforted him.

"What's the matter?" Wu Hao was still anxious to know what happened.

"We have just found a very ideal product packaging material, which is the airbag you provided. According to the evaluation of experts, using this material can greatly reduce the chance of product damage and greatly enhance the reliability of the product."

Da Bin happily replied.

Because they are all carbon materials, they have high chemical stability. This film is an excellent material for adhering capacitors. By increasing the inner skeleton, it can also be used as the outer shell of the product. Since pistol bullets cannot penetrate, so In terms of safety, there will be a great guarantee.

"So that's it, it seems that I'm hitting the wrong target!" Wu Hao is very happy that his own things can help the project to speed up.

"It's a timely help. We experimented with many materials and found them inappropriate. I didn't expect you to solve them!" Dabin was very emotional.

By chance, Wu Hao solved a big problem and greatly accelerated the progress of the project.
