Upgrade the world from Hongmeng system

Chapter 296 Shock brought by new materials
According to the company's instructions, Mr. Bai designed a large cargo aircraft with a graphene hydrogen air bag as the skeleton. This design is mainly to obtain the maximum load capacity for transporting more cargo.

The design requirement is to meet the transportation of 20 tons of cargo, using four large multi-stage ducted engines, the weight of the battery alone will reach 5 tons, and the range needs to reach 8000 kilometers when fully loaded.

"This is a large transport aircraft, do we have such a powerful engine?" Xu Longfei was very surprised.

Let me take you to see the newly designed transmitter, and it should be tested today.

Sitting on a battery car, the two came to a factory building where a black aero engine was being tested.

The engine hummed and the fans at all levels were running at a slow speed. After confirming the status, the current suddenly increased and the engine made a huge roar.

"This shaftless duct reaction is so big!" Xu Longfei was shocked.

"You think it's the little thing that Haotian Technology made at home, but this is the real aero engine. Once the energy density problem of the battery is solved, the shell and fan blades made of carbon fiber can greatly reduce the energy consumption of the engine. Weight, plus the use of the latest hydrogen airbag material for the entire fuselage, the empty weight of the whole machine will be controlled at about 10 tons, which includes the weight of the battery.”

Mr. Bai excitedly introduced that as a new generation of designer, he had the honor to participate in this project. When the single-layer graphene mass production technology was broken through and the first graphene trial production battery rolled off the production line, he received a message , the aviation system is pre-researching a shaftless ducted engine, which will replace the existing propeller engine.

When he saw the real thing for the first time, he was also very shocked. The main reason is that this engine is very light. There is no transmission mechanism, no combustion mechanism, no lubrication system, and the whole structure is greatly simplified. The heaviest parts are those High suction permanent magnet material, the weight of the engine is only 5% of the traditional engine of the same power, two or three people can lift it, the thrust-to-weight ratio is amazing.

What is even more shocking is the shell of the high-pressure hydrogen air bag, which can be lifted by five or six people. It looks so huge, but it is actually very light. The heaviest part of the whole aircraft is the landing gear, because it is made of conventional materials. , It is said that the graphene ultra-light landing gear currently being developed can further reduce the weight of the aircraft.

"The key is that this kind of engine is still very cheap!" Xu Longfei has built two such engines himself, and knows that its cost is very low.

Because the structure is very simple, after using the cloud technology, the speed of each fan and the adjustment of the power output will be calculated by the central control system, and the engine and the main control chip are all left.

"Yes, the overall cost of the aircraft can be reduced by half, and the operating cost can be reduced to one-third of the original cost. Air transportation will usher in a new great development."

Mr. Bai is an expert in aerodynamics. The reason why he chose to join Feimeng Technology is because he has taken a fancy to the great opportunity for the future development of civil aircraft.

"By the way, we have developed a passive safety landing device at Haotian Technology. Under the premise of throwing away the battery and engine, it can use a parachute to glide smoothly to the ground."

Xu Longfei couldn't hide his excitement, and told them what Wu Hao asked them to pre-research.

"Oh, and this thing? However, it seems reasonable to think about it. After all, the body is very light. Even if it is full of people, it is still possible to land safely through a large parachute. This device is worth studying!"

Mr. Bai seemed to have come to his senses and felt that this idea was feasible.

"I'll show you the design when I go back. We've tried it before, and it can greatly increase the safety factor."

"Okay, let's go, let's go back to the studio and talk!"

The two were just about to leave, but they were stopped by someone, "Boss Bai, our drone is going to be tested, do you want to take a look?"

Following the direction indicated, the two came to the test flight site. There was a weird plane on the runway. There were two huge shaftless ducts on the left and right sides. It was a bit like a helicopter, but it was not a helicopter. It was more like a plane in a sci-fi movie. Vertical take-off and landing aircraft.

The shaftless ducted engine was started, and the plane slid forward tens of meters, left the ground, turned a few times in the air, flew very smoothly, and finally landed vertically on the test flight field.

"Old Lin, the matching of your flight control system is better than last time!"

"It's okay. This thing is too low in weight when it is flying empty, and it is a bit floating. After it is loaded, it is very stable."

"This is the trouble of the new type of aircraft. I used to think the airframe was too heavy, but now I find it is too light. It needs a counterweight to be easy to control."

"It's actually okay. According to the original expectation, this thing is used to transport energy storage equipment. There is not much difference in weight between a charged battery and a dead battery."

"That's right. Anyway, if it is fully loaded and then flies, there will be no stability problems in empty flight. If it needs to be repaired, it will be very easy to disassemble it and transport it by vehicle."

"Dabai, if this machine passes the acceptance test, we want to make a bigger one. Let's see if it's good to adopt this design."

Lao Lin handed over a sketch of his imagination. This aircraft uses four shaftless ducts. The cargo compartment of the fuselage is large and long. The design load is 20 tons. This data really surprised Xu Longfei.

"Old Lin, I will refer to your plan for the shape of the aircraft, but the specifics still need to be demonstrated. You continue to test the flight, and I will go back and adjust the design plan."

"Please, Dabai, make sure my design is faster than theirs!"

"no problem."

The two returned to the studio in a battery car.

"Boss Bai, why did Lao Lin rush to produce a 20-ton transport plane?" Xu Longfei was curious.

"Because this is a model that the group needs to purchase in large quantities, we have a new energy plan to build more solar power stations in remote areas to replace thermal power plants."

President Bai explained.

"Isn't the power station transmitting electricity through the grid?"

"In many remote areas, there is no power grid, but where there is enough solar and wind energy, such as in the desert, in the Gobi, or in the mountains."

"That is to say, in the future, electricity will be transported by airplane?"

"Airplanes will be used in remote areas, and then they will be concentrated along the railway line to solve the problem of battery delivery through mixed transportation."

"You can still play like this! After the breakthrough of graphene capacitor battery power storage technology, the application is really too wide."

"There are more that you can't think of. I feel that I am a little behind the times."

"Before I came here, I thought I would do a roller coaster project, but I didn't expect to come here to do a transport plane."

"Roller coaster?... There is really a flying car, and it has been arranged for mass production, but the order from the science and industry department at that time was still early for civilian use."

Technology changes life, and the changes are really changing with each passing day.
