Chapter 424

Relying on the positioning system as the only navigation guidance, the modified 737 started to slide out in strict accordance with the predetermined route at the moment of starting the engine, and the positioning point of the navigation module was in the middle of the aircraft, so the center line of the aircraft was always the same as the center line of the connecting line. When the aircraft started to slide, all the lights of the airport went out in a flash, which was connected to the front of the aircraft The lights were also turned off by Zhang Yunfeng. The cockpit was full of lights, and it was dark outside. As a result, people could only see themselves when looking out inside the plane. In addition, everything outside was shrouded in darkness and unrecognizable.

If it's in this visibility, it's not a civil aircraft, even a military aircraft can't take off at all, because now the pilot's sight distance is equal to zero, there's no way to know everything outside, and even they can't find the location of the runway. However, with the help of the Dongchen positioning system, this aircraft is very clear about the set route, even if there's no one outside He visibility, however, through the large screen simulation image of the positioning system, the position and speed of the aircraft at this moment are very clear!

On the screen, the airport runway is displayed in the form of a plan, and the aircraft itself is not a simple positioning highlight, but a year-on-year reduced 737 simulation map as a representative, to simulate every action of the aircraft at this time, and because it is year-on-year reduced, it is almost a real-time thumbnail.

A crowd of people crowded around the display screen of the positioning system, Liu officer said: "the next corner will enter the runway?"

Zhang Yunfeng nodded and said, "when you enter the runway, the plane will start to accelerate at the center line. When you reach the speed of raising the front wheel, you will automatically adjust the flap to take off."

A nearby expert said with some concern: "once the plane doesn't really find the runway, or slightly deviates a few degrees, and doesn't align the runway, it will start to accelerate. Once it rushes out of the runway, we will be finished. In addition, once it reaches the decision speed, if there is a little deviation in the plane's orientation or the plane doesn't take off automatically, then We've got a lot to lose. "

Zhang Yunfeng said calmly, "since Dongchen is going to launch this technology, it must be mature technology. Besides, as you know, Dongchen is now starting to acquire Airbus. Do you think if Dongchen doesn't have several high-end technologies like Assassin's mace, it will go to great pains to acquire Airbus?"

As soon as Zhang Yunfeng said this, everyone woke up. Yes, Dongchen was already in the process of acquiring Airbus. Without leading core technology, they would not even focus on this industry.

At the same time, people on the plane also clearly felt that the plane began to turn.

"Everyone should go back to their seats and have a real-time video in the cabin to see everything in the cockpit," said Zhang

When they heard this, they hurried back to the cabin. After the plane turned, they waited for five minutes at the end of the runway. When the five minutes came, the engine of the plane suddenly increased, and the engine began to make all-round efforts to speed up and taxi.

In this case, even if the plane suddenly catches fire, the plane must take off, go to the sky first, and then try to land.

All of these people are in a cold sweat when the engine is working. Although they can't see the outside and feel the speed of the aircraft at this moment, they can also feel that the speed of the aircraft has become faster and faster from the increasingly strong sense of turbulence.

“v1！ V1! "

The cold computer prompt sound sounded in the whole cabin, and the plane has reached the V1 decision speed. An expert who has some knowledge of civil aviation said: "OK, we can only take off if we don't stop at V1. Let's leave it to fate."

Voice just fell, people clearly feel that the aircraft's nose began to lift, the aircraft took off!

A completely unmanned aircraft, in principle, an unmanned aircraft, naturally does not have the qualification to carry people, after all, this thing leaves people, no one thinks it will really be reliable.

The plane has started to climb. It's just like the normal feeling of flying. If you don't remember that there is no ghost in the cockpit, people won't have any special feeling. And the plane started to fly around the airport value on the established route as soon as it went up to the sky. Then it flew over at the last side, turned around, and began to prepare for landing.

People are watching the distance between the aircraft and the runway at this moment, the height of the aircraft at this moment and the descent rate. It seems that everything is very normal, and the height of the aircraft is constantly decreasing, and the distance from the runway is constantly being pulled closer.

A series of preparation processes for landing are automatically completed by the aircraft. The flaps are opened, the engine thrust is reduced, and the altitude of the aircraft is lowered steadily. A few minutes later, the rear wheel of the aircraft sends a clear touch to the ground. Then, the front wheel touches the ground, and the speed of the aircraft quickly drops, which makes everyone feel relieved.

The cheers of.

For the staff outside the airport, the pilotless test flight was extremely successful. Before the aircraft took off, the position of the front and rear landing gears were marked with white sidelines on the ground by the staff. When the aircraft came back, it was still parked in the painted sidelines. The staff outside were the backbone of Dongchen aviation engineering. They had known Zhang Yunfeng for a long time After the acquisition of Airbus, Dongchen will begin to produce its own passenger aircraft. Now, such a powerful positioning system has become the most accurate guidance system in human history. If Dongchen's future aircraft will have such unmanned capability, it will be enough to change the development and process of the entire civil aviation industry.

but Zhang Yunfeng knows clearly that if a super biological chip like a super learning system is not developed, then the computer can never be compared with people. Although the automatic driving system seems to be far higher than the human limit, it will never abandon the pilot's essential factor. It may be true to develop driverless passenger transport models. When encountering any emergency, the human brain's ability to respond is almost beyond that of computers. What's more, human beings have the ability that computers do not have, which is the role of experience.

However, even if it is impossible to abandon the important factors of human participation in a short period of time, this system is enough to make Dongchen's future passenger aircraft take off and land easily at any airport and in any visibility if it has powerful and accurate navigation. One day, maybe Dongchen's passenger aircraft will be guaranteed with Boeing, Airbus and so on There are a large number of airplanes shuttling along the world's air transportation lines. At that time, the following situations are likely to happen.

First of all, there are many flights to Yanjing airport from different directions. Once Yanjing enters the fog state and the airport is closed, all Airbus and Boeing aircraft will temporarily choose other airports in the surrounding cities for alternate landing. However, Dongchen aircraft only needs to open the autopilot and transfer the data of a runway in Yanjing Airport, so the aircraft can easily Automatic landing without vision.

In addition, if one day, Yanjing is affected by the heavy fog, even the departure flights are forced to stop. When tens of thousands of passengers stay in the airport, only Dongchen aircraft can obtain the departure permission from the airport tower. In this way, airlines all over the world will find a problem. If they are equipped with Dongchen aircraft, their costs can be further reduced.

At that time, the work of air traffic control will be much easier. When an aircraft is allowed to land, they only need to send the runway data to each other. For convenience, they can land quickly and safely in strict accordance with their own requirements, and then enter their respective stands quickly and safely.

What's more, Zhang Yunfeng is going to use the assassin's mace technology on the Dongchen passenger plane, which is far more than that.

After this test, the military is very interested in the positioning system of Dongchen. I wish it could be equipped with the positioning system of Dongchen for the domestic military aircraft. Once the positioning system of Dongchen is equipped, even if the autopilot is not refitted, the pilot can take off without sight distance according to the data provided by the positioning system of Dongchen. This advantage It will be epoch-making for Dongchen and the whole world. When the

ladder car opened, a group of experts and investigators walked down from the plane. When they saw that the aircraft wheels were re fitting in the front line and never seemed to move, they all looked surprised. The Dongchen's hand was really shocking, and shocked that they had to admit that the advanced nature of the system was no longer available.

Beidou experts finally know what it's like to be helpless this time. Dongchen has done what they have done in the past 20 years in a month, and it has done countless times better than them. Dongchen's technology has already become a leader in the positioning system of the whole world.

After getting off the plane, one of Beidou's engineers asked with surprise and modesty: "Mr. Zhang, I would like to ask you, Dongchen has developed so many sets of terminal equipment for this positioning system. What are the main differences? Are necessary castrations performed on portable mobile devices? "

Zhang Yunfeng shook his head and said: "we will not deliberately tighten the functions and performance of the product. For example, the mobile phone module of Dongchen positioning system can also realize three-dimensional navigation. However, due to its weak processing capacity, its performance and function are far less than that of the airborne positioning module, so it does not have the function of 3D simulation or too many auxiliary computing functions However, with the continuous improvement of the terminal, we have added a large screen and more powerful dual processing chip to the handheld terminal, so the function and performance of the professional handheld terminal is much better than that of the mobile module. "

Said Zhang Yunfeng calmly: "in fact, we prefer to use on-board or airborne. In the future, the functions of automatic driving and take-off and landing without sight distance will also be directly transplanted to the large passenger aircraft of Dongchen, becoming the standard function of Dongchen technology.

"Standard features?" The man was stunned.
