Genius of the Rules-Style System

After the flying car was assembled, formal testing began.

The first item is to conduct a fixed test.

The fixed test process takes a whole day, mainly to test the performance of the changing wheels. When the aircraft turns on the anti-gravity system and rises, the wheels will retract the tire part, spread out the surrounding blades, and become a turbine that waves the air. The turbine has a very high rotational speed, and its continuous rotation will create a forward force on the car.

At the same time, the micro-turbocharged engine will also start simultaneously.

The wheel-changing turbine and the micro-turbocharged engine together form a forward force, pulling the car to accelerate and fly forward.

This force has an upper limit and will reach a balance with the air flow and the resistance of the car at a certain speed. This is used to calculate the maximum speed of the flying car in flight.

Although it is only the theoretical maximum speed, it is also very useful for reference.

After a day of testing, the various parameters of the flying car reached the standard, the performance of some internal components was also adjusted, and the top speed of the flight was close to more than 500 kilometers per hour.

This is quite an astonishing speed.

Although there is still a gap between the top speed of airplanes, flying cars are not built for high-speed flight. They can reach 500 kilometers per hour, which means that it only takes less than three hours to travel from the capital to the Magic City. , almost the same as a real airplane.

"As far as the power of the car is concerned, when the flight speed exceeds 100 kilometers per hour, the micro-turbocharged engine is the main source of power. At this time, the effect of changing the wheels is already very small."

After passing the wind test, technicians came to the conclusion, "Because the rotation speed of the turbine will be offset by the flight speed, and when the flight speed exceeds 350 kilometers per hour, the turbine will even hinder the speed."

"So, when the speed exceeds 200 kilometers, you can actually shut down the turbine directly."

"But in the initial acceleration phase, the turbine is very important."

"At this time, the power provided by the turbine engine is very limited, or even negligible."

"However, this is also the biggest problem with acceleration in the flight state, because the acceleration provided by the turbine is limited, and the fastest acceleration in the flight state is only about 17 meters per second."

This acceleration is really not fast.

Even ordinary civilian cars can accelerate to 100 kilometers in five seconds. For example, unlimited power cars can accelerate to 100 kilometers in three seconds.

In the flight state of the flying car, it takes six seconds to accelerate to 100 kilometers. The acceleration speed can be said to be very small, but when considering the flight state, deceleration is not needed most of the time, and it has little impact on use.

The various performances of the flying car have still achieved satisfactory results.

After a full day of fixed testing, a test flight was conducted the next day.

The first test flight did not require human operation. Instead, it relied on a simple system that allowed the aircraft to rise vertically in an open field, then slowly accelerate and fly around, then return to the original place.

This is the first test of the test flight.

After the first test is over, there is the second test, which is to accelerate the car to 100 kilometers per hour, and then directly turn on the reaction power system to achieve high-speed flight.

Ordinary civil aviation aircraft will only raise their heads and take off into high altitude after accelerating more than 300 kilometers per hour. However, flying cars rely on an anti-gravity system and can achieve vertical lift-off. They do not need to accelerate too fast. 100 kilometers After hourly acceleration, you don't even need to change the wheels after taking off. You can continue to accelerate flight by relying on the micro-turbocharged engine.

The maximum speed of this test flight will reach 250 kilometers per hour. The intelligent system will control the car to circle in a large circle and then return to the original place.

Regardless of whether it is the first test or the second test, there will still be technicians in the cockpit. The technicians will wear safety suits that resist physical collisions. Even if the car malfunctions in the air, the staff wearing safety suits will jump out. In theory, Neither will be harmed too much.

Of course.

When facing security issues, no one can guarantee that no problems will arise.

Therefore, before the test started, Zhao Yi explained many things to the technician who came up, reminding him that safety was the most important thing.

The staff on the flying car, wearing thick safety suits, will definitely not be able to perform subtle operations, but they can perform the two most important operations.

One operation is to shut down other energy-consuming devices so that all electric energy can be fully supplied to the anti-gravity system to ensure the operation of the anti-gravity system.

This is one of the solutions to ensure safety.

The other is to slow down, just like applying the brakes on a car. You can also control the deceleration during flight by unfolding the drag wings and turning off the solar energy transmission supply to the combustion chamber of the micro-turbocharged engine.

When a flying car loses engine power and generates a lot of resistance, it will naturally slow down quickly.

The latter is something that ordinary airplanes cannot do.

Turbine engines used in ordinary airplanes generate high heat from the fuel supply during combustion. The engine can isolate the fuel supply, but because fuel has been delivered, the high temperature in the combustion chamber will not directly become normal due to cutting off the fuel. temperature.

The newly designed micro-turbine engine is different. The source of high heat in the combustion chamber is supplied by solar transmission. Turning off the two small space transmission and receiving devices will naturally quickly reduce the engine power, and even directly cause the engine to become an obstacle to flight.

soon.

Test preparation begins.

Qiu Chengwen, Edward Witten and others arrived at the open test venue early. At first, they thought it was a real test flight, and they both shouted that they wanted to go straight up and try it.

Of course they knew that the test flight was risky, but because all the data in yesterday's basic test were very normal, they felt that there was no problem with the test flight.

That is of course impossible.

"I also want to go up and try." Zhao Yi said with a smile, "But you see, our test pilots have to wear thick safety suits."

"--Right."

Qiu Chengwen was immediately disappointed, but continued, "Zhao Yi, right in front of me is my childhood dream. I remember when I was seven years old, I was standing on the roadside with my father and saw a very beautiful car driving by. "

"At that time, I was envious of people sitting in cars, so I told my father that I must drive a cooler car in the future."

“My dad asked me, what would be a cooler car?”

"What do you think my answer is?"

"Flying car?" Zhao Yi said the answer directly, which made Qiu Chengwen feel even more depressed. He was speechless for a long time, and then he held back a sentence, "You are right, but what I said at the time was , I will operate the car to fly, and when the time comes, I will take you to travel around the world."

"My father was very happy at the time, but what he was happy about was not the dream I told him, but that he felt that I finally showed the same virginity as other children of the same age."

Everyone else listened in silence.

At first, I thought Qiu Chengwen was talking about an interesting childhood story, but in the end, when I listened to it, I felt different.

Zhao Yi's understanding is to pretend, and his interpretation of the story is, "I have been different from other people of the same age since I was a child. I am a super genius and do not have the innocence of a child."

The reason for his understanding is probably that he has no similar experience at all.

When he was young, he was very mediocre.

To be precise, he had always been very mediocre in his previous life.

Edward Witten felt deeply about it and understood Qiu Chengwen's mood very well. They were both considered prodigies when they were young, and they are about the same age now. Occasionally, they would be very emotional when recalling the past.

However, no matter what ideas they have, flying cars are indeed something many people have dreamed about.

Now the world's first flying car is about to begin testing before our eyes, and everyone is looking forward to it.

In the eyes of everyone, the car slowly rose up, and then slowly accelerated. After about ten seconds, the speed was about fifty miles, and it circled in the sky and returned to the ground.

During the flight of the car, the micro-turbocharged engine was not turned on. It relied entirely on the car's turbine to fly, and the power was not very fast.

This is a speed setting.

Only above an hour does the turbocharger start.

After the technician got off the plane, he made a report, "During the entire test process, there was no problem with the balance, but the acceleration was still slower than expected."

A technician came over soon and provided specific data.

Zhao Yi looked at it carefully and found that the data was within the deviation range and basically had no impact.

The next day is the accelerated test.

This time, Qiu Chengwen still wanted to go up and experience it. Zhao Yi felt very headache, but still dissuaded him, and then said, "If there is no problem with this test, wait a while, I will go up with you, but you must Wear safety clothing and fly slowly.”

"--All right!"

Qiu Chengwen thought about it and agreed. After all, safety is the most important thing.

The second test is much more dangerous than the first, because the car needs to accelerate to 100 kilometers per hour before it turns on the anti-gravity system and takes off, with the maximum speed reaching 250 kilometers per hour.

This speed is very fast.

If something goes wrong midway and the car suddenly stops operating, it will definitely be a major accident. The technicians above may be seriously injured or even in danger of death.

A lot of people are nervous.

But the test process was still very smooth. After the flying car accelerated to 100 kilometers per hour, it turned on the anti-gravity system and immediately ascended and flew. Then the car turned on the micro turbine engine and continued to accelerate, making a full circle, up to a few meters away, and even some Unable to see it, he slowly turned back, slowed down and landed on the ground.

"The test was very good."

The technician reported, "The maximum flight speed was 263 kilometers per hour and the altitude was 510 meters. The whole process was very smooth."

"All data are normal."

After the second test, everyone else felt relieved.

Zhao Yi was also looking forward to going up there to try it out. In fact, he was more eager to go up there than Qiu Chengwen, because it was a flying car he designed himself, and it looked very cool.

In addition, a very important point is that he judged that there are no problems with flying cars, that is, there are no technical safety risks. As long as they fly at low altitude and slow speed, there will be no safety problems.

It's a pity that it's impossible for others to let Zhao Yi get in the car without any safety.

In the end, Zhao Yi and Qiu Chengwen each wore a set of safety suits. The thick protective suits even covered their faces. There was no experience at all in the car.

The flying car slowly circled in the air, and the ground operators even planned to fly at a speed of no more than thirty miles.

The whole process was like making a merry-go-round, rising steadily into space, and then falling steadily. After the car landed, Zhao Yi quickly took off his helmet and complained, "It's better to let you go up by yourself." Well, it’s so boring.”

"I think so too." Qiu Chengwen shook his head in disappointment.

The two looked at each other and laughed.

Zhao Yidao said, "Don't worry, let's wait until next time. With continuous testing, safety will be guaranteed in a few months."

"Now that the car's performance has reached the standard, the next main improvement direction of the car is to ensure safety."

"I'm really looking forward to it!"

Qiu Chengwen sighed.

——

On the way back to the experimental base, several people kept talking about flying cars. Qiu Chengwen kept talking about ordering one in advance, but it was not easy to realize his idea because flying cars were still far away from being launched.

There are currently two important factors hindering the launch of flying cars.

An important factor is the approval of the superior department.

It is really not easy to get approval for flying cars, because there are currently no relevant laws in China, let alone traffic control issues. Whether flying cars are within the scope of traffic control is a matter that can be argued for a long time. question.

In addition, the flight path is also an issue.

If there is only one flying car, there will naturally be no problem, but after it is officially sold, there may be many flying cars on the road, and then the flight path of the car will become a problem.

All cars fly at low altitudes and cannot fly randomly in the sky. They must follow a precise route.

How to define the route?

Very difficult.

This is the most time-consuming. After applying to the superior, you need to wait for a long time. If it can be solved in one year, it is already quite good. Sorry, it may take even longer.

The second point is the issue of security review.

The safety of current flying cars is definitely not up to par. Although some designs have been made to ensure safety, no one can guarantee that no problems will occur.

Flying cars cannot meet the safety standards of ordinary cars, so they cannot pass the safety review. That is, the relevant safety design needs to be continuously upgraded. Even the original design requires a lot of improvements and a lot of additions. Device goes in.

Now let alone conduct a safety review, we don't even dare to allow people to test drive at will. Any problem will be a major incident.

The flying car can only be placed temporarily and is slowly being improved. For the time being, it can only be used as a display car.

——

When Zhao Yi and others returned to the experimental base, they did not know that news had already spread in public opinion.

Although the test site is empty, there is a small town ten kilometers away. Many people have photographed the flying car, and there are even clear videos.

This caused a heated discussion in public opinion.

There is a hot discussion that is the most interesting and the most popular--
