Upgrade the world from Hongmeng system

Chapter 291
On December 2027, 12, Wu Hao immediately got the trial production version of the graphene capacitor battery, a total of 12 sets, all of which are high-power battery packs dedicated to electric vehicles.

Xu Longfei led people to re-adjust the engine according to the output power of the battery pack. After testing, this shaftless ducted jet engine with an 8-stage compression fan had a thrust of 85 kg, and the total of the two engines was 170 kg.

And Luben's airbag frame has also made progress. A frame like a supercar has been built. Two engines are built into the left and right sides, and the battery is built into the chassis.

The weight of the body using the hydrogen bag frame is no more than 1 kg after weighing, the weight of the battery is 50 kg, the total weight of the engine is 80 kg, plus the weight of other equipment, the total weight is about 150 kg, and the thrust-to-weight ratio is too high 1, barely able to take off and land vertically.

Of course, this is the result of the absence of people. If people are to be carried, the structure of the car body and the thrust of the engine need to be redesigned and optimized.

In order to test the safety of the vehicle frame, Wu Hao recruited a strong man to conduct destructive experiments on the vehicle body with a sledgehammer, steel nails, electric drill, and air gun nailer. Ten million, causing a huge sensation.

The engine has been improved, and four air outlets are set in the car body. When the nozzles at the rear of the engine are closed, it can provide vertical lift, allowing the roller coaster to take off on the spot.

The cockpit glass on the frame is made of lightweight polyester and cannot be opened, and there is a simple air-conditioning system inside.

Various parts of the vehicle have been manufactured one after another, and the manufacturing process has been broadcast live in stages. The low-altitude take-off and landing experiments on the ground have been done many times, and the date of the official test flight is set for today.

The test flight uses unmanned technology and is controlled by a set of high-end virtual simulators.

Since it was the first application of graphene capacitor batteries in aircraft, the live broadcast attracted a large number of viewers, and the live broadcast platform also put the content at the top, and the audience traffic quickly exceeded 3000 million. By the time the host entered the venue, the number of viewers had exceeded [-] million.

Today is a big day, several main officials of Haotian Technology are all present, Wu Hao is watching the test flight outside, Gu Fan and Wang Hao are in the control room to ensure that the equipment is running normally, and Cao Yongliang is helping to coordinate the live broadcast.

"Hello everyone, audience friends. Welcome to the verification flight experiment of the roller coaster. Before that, we have done the test of leaving the ground. Today, the prototype car will officially fly to the clouds."

"This test flight activity has been reported to the relevant department and has been approved for flight. The flight altitude will not exceed 500 meters, and the range will not exceed a radius of 10 kilometers. Today's weather is very clear and the wind speed is not high. It is very suitable for test flight. I wish our roller coaster a smooth ride to the sky."

"The first thing we have to do is a conventional roll take-off test, and the expected roll distance is 500 meters."

Since the thrust-to-weight ratio exceeds 1, the power is very abundant, and it can achieve short-distance take-off when the power is fully turned on.

The roller coaster was pushed to the end of the runway by Xu Longfei and two friends, the three evacuated, and a pair of main wings were opened, which were mainly used to increase lift and reduce power consumption.

The test flight officially started. As the engine entered the state, there was a sound of "boom boom boom..." from the back of the car, which felt a bit like a fighter jet taking off.

The bullet screens in the live broadcast room began to flash.

"This engine, the sound is interesting!"

"Can it be used on civil aircraft, such as vertical rotorcraft?"

"I don't know if it can be used on a helicopter. Anyway, propeller planes are definitely fine."

"Used on a propeller aircraft, the economy should be very good."

"..."

Everyone was discussing enthusiastically in the live broadcast room.

The take-off was very smooth, and there was no situation of looking up into the sky. The screen switched to the image of the vehicle cockpit. As the roller coaster climbed, the buildings on the ground became smaller and smaller, and the speed car entered a stable driving state.

In the air, there is not a lot of noise in the cockpit of the roller coaster, only a slight "humming" sound, which is similar to the motor noise of an electric car.

Through the external camera, you can see the synthesized images around the car body in the cockpit, and the surrounding situation can be seen at a glance.

Judging from the ground observation, the flying speed of the roller coaster is not fast, similar to that of a helicopter, and the movements are very gentle when turning, and there is no sharp roll.

"This test flight is a bit boring!"

"There's no way this is a car, it's mainly used for civilian use. You can tell by the simple cockpit, and it doesn't even show the atmospheric data."

"This stuff is just a gimmick now."

"It can't be said to be a gimmick. After all, it has practical significance. Through the test flight, it tells us that in the future, flying into the sky will become cheap and will no longer be so expensive. You must know that the cost of flying with a helicopter is very high. If you turn around casually, the cost will be several hundred."

"It would be great if I could drive it myself!"

"Haotian Technology can always achieve some strange things, which is quite fun."

"..."

There were heated discussions in the live broadcast room.

At this time, the test flight was over, and the roller coaster began to land. The rear air jets were closed by a partition, and four air jets were opened under the car. The speed of the vehicle decreased rapidly, and the body slowly descended to the predetermined position until the four wheels landed smoothly. The power supply in the car was cut off, and the test flight was a complete success.

"This landing gives full marks!"

"The most beautiful part of the whole test flight is the landing, it's so stable!"

"From this point of view, this product is still promising. The entire test flight lasted 15 minutes. In the final picture of the test flight, I saw that the battery is still two-thirds, which means that the battery life is expected to exceed one hour."

"It also depends on the vertical take-off, that stage is the most power-hungry."

"..."

In the live broadcast room, there were thumbs up, expressing that the process was very good.

Xu Longfei used a special battery replacement trolley to easily replace the battery on the bottom plate. The whole battery replacement process only took half a minute. The whole process is fully automated, and the vehicle automatically raises the body, which looks full of technology.

Then came the vertical take-off test, which is today's highlight and a highly anticipated project.

The roller coaster reappeared and completed a round of automatic monitoring. After confirming that the aircraft was in good condition, it began to close the air outlet of the rear engine. The side engine jets were reopened.

"The thrust for takeoff is still not enough, it's a bit reluctant, and it consumes a lot of power!"

"Indeed, the cockpit has only two-thirds of the battery left. It will land later, and the cruising time is estimated to be half an hour at most."

"As a prototype, this test flight is still very successful, but there is still a long way to go for practical use."

"..."

The test flight revealed many problems. Although it flew, the process was a bit procrastinated and not perfect.

Wu Hao is very satisfied with the result. He has obtained the attention he wanted, and someone will definitely contact him in the future, seeking to develop this product together.
