DJI's drone flight programming was originally developed for nighttime performances, so the effect is naturally best after dark.
When the sky turned dark, many people exclaimed.
All the drones were lit up with lights of various colors, and the night covered the drones' fuselage, leaving only the lights moving in the sky.
If it were just a light, it would look more like a firefly alone. But the lights of thousands of drones were turned on at the same time, forming a magnificent pattern in the sky.
Different from the picture of fireworks blooming, it is only beautiful for a moment. As the fireworks dissipate, no matter how beautiful the pattern is, it will quickly fade and eventually disappear.
The light show formed by the drones flying in a team can stay in the air for a long time, like an eternal picture.
At this time, the pattern formed by the drone formation is very simple, just numbers and letters.
【2008, Beijing welcomes you】
But the effect was very good, attracting the attention of Li Jianguo and others, who were amazed and amazed.
Soon, under the operation of the staff, the formation changed.
This time it is no longer simple numbers and letters, but a flying and dancing dragon.
The giant dragon flew through the air, its body's posture constantly changing, sometimes rolling, sometimes climbing, its lifelike appearance was completely beyond everyone's imagination.
Many of the officials present were not technical experts. When they saw the aerial pictures, they suddenly discovered in shock that when did domestic technology develop to this extent?
But I have to say, as Xiao Qian said, if such a performance appeared at the Olympic opening ceremony, the effect would be absolutely amazing.
However, everyone was very steady and did not express their opinions easily. Instead, they watched the drone's performance continue.
For UAV formation performances, the most difficult thing is the development of the formation program and the support of the hardware. After these two aspects are satisfied, the rest is just a change of data.
With the support of Huawei and Starlight Technology, DJI’s entire grouping plan was very perfect. During the thirty-minute performance, a total of ten different groups of patterns were unfolded, each of which was perfect, and there were no accidents or accidents.
"What do you think?"
Seeing the drones exiting the scene in an orderly manner, even more efficient than humans, Li Jianguo began to solicit everyone's opinions.
One committee member took the lead and asked: "Mr. Xiao, Mr. Wang, what is the failure rate of your drone? You know, in such an important occasion as the opening ceremony of the Olympic Games, there cannot be any problems."
Wang Tao was a little frightened, but Xiao Qian was fearless.
"Special matters are handled specially, and we will concentrate our efforts to ensure the operation of the equipment."
He was afraid that these responsible persons would not be able to make up their minds, so he added another sentence.
"During the military parade, so much equipment can be guaranteed not to malfunction. Even some of our drones will not fail in a short period of time."
When he said this, everyone's confidence really increased a lot.
Think about it, during the military parade, so many types of equipment can be displayed perfectly. If DJI goes all out to ensure the perfect performance of the drone, there will definitely be no problems.
Seeing everyone's expressions of excitement, Li Jianguo made a decision.
"Let's do this. After we go back, we can formulate a written report and submit it."
His meaning was very clear, that is, the matter should be left to the higher authorities for decision. In this way, the psychological burden on those present would not be so great.
Li Jianguo and others withdrew, but Xiao Qian did not leave.
The content of the drone grouping test conducted by DJI is far more than that, and it is not just for the opening ceremony of the Olympic Games.
Now that there are no outsiders, Xiao Qian finally doesn't have to hide and tuck in.
"How is the development of your fixed-wing drone going?"
Wang Tao laughed heartily, fully demonstrating his hobby as a technology geek.
"With the help of the military, progress has been very rapid. You see, this is the first fixed-wing drone we have developed."
The warehouse in the distance slowly opened, and under the tug of a trailer, an aircraft that was completely black and very similar to an ordinary airplane was towed to the runway.
Xiao Qian hurried over and took a closer look.
The height of this drone is almost to his waist, with complete wings, tail and vertical tail, and the landing gear below can also be retracted into the fuselage.
The only difference is that this drone does not have a cockpit and does not require people to sit in it and fly it.
An officer caressed the aircraft fondly and said confidently: "Although this fixed-wing UAV cannot be compared with manned aircraft in terms of speed, altitude and endurance, its cost is very low. During combat,
No matter how much the loss is, it doesn’t feel too bad. With firm control of the air, such a drone will become a trump card for getting twice the result with half the effort.”
DJI is researching drones, and the military is also researching them, but in different directions, but they are complementary.
For example, DJI has received support from the military in the technical fields of aerodynamics, materials, and engines, while the military has received help from DJI in the fields of flight formation procedures, avionics, and flight control.
In addition, there is another company that played a huge role in the development process of this fixed-wing drone.
That is Huawei.
There are not so many communication satellites in the sky now, and the transmission distance limit of wireless networks is very large. This also greatly affects the radius of activity of drones, which is far from being compared with those of the same kind later.
The military field is okay, but the civilian field is the most head-scratching.
If communication is not good, then controlling a drone from a long distance is just a mirror image. The only way is to unite the most technologically advanced companies in the country to jointly solve technical problems.
In Xiao Qian's view, the worst thing about Chinese technology companies in the previous life was that they regarded each other as competitors. In the domestic market, they wanted to kill their opponents, but in the international market, they were all cowardly.
Originally, the strength of Chinese enterprises was not that outstanding and they could only work on their own one-third of an acre of land. When will they be able to take a dominant position in the international market?
Therefore, he attaches great importance to alliances between enterprises, and even does not hesitate to transfer enough benefits for this purpose.
Apart from anything else, the benefits have been reflected in this drone development process.
Without him uniting several companies, DJI's drones would not be available any faster than in previous generations. It would be even more elusive to achieve market competitiveness.
A truly good enterprise must not only be able to develop and grow on its own, but also be able to unite enough allies to form market control, and at the same time make corresponding contributions to the country and the nation.
"How high can such a fixed-wing drone fly? How long is its endurance?"
Wang Tao explained it himself.
"The flight altitude can reach 1,500 meters, and the endurance time can reach three hours."
Xiao Qian was not satisfied and continued to ask: "Where is the load?"
Wang Tao knew what he was going to ask and said: "It can be paired with a five kilogram communication relay station."
Xiao Qian looked at the person in charge of Huawei on the other side.
The man nodded and helped Wang Tao prove it.
"Through our joint research and development with Starlight Technology, we have achieved the miniaturization of the relay station. I have to say that Mr. Xiao's idea is really creative."
What idea did Xiao Qian put forward?
In the current situation of insufficient wireless network communication, drones cannot fly long and high distances because the control center will lose contact with the drone.
Originally, DJI was unable to solve this problem and could only limit the flight distance and altitude of the drone to one kilometer and five hundred meters respectively.
But Xiao Qian got inspiration from WiFi and proposed the concept of information relay to increase the flying range of drones.
The method is to load a communication relay station on the drone, and then use the relay station to make the transition in the air. Wouldn't it allow the drone to fly farther and higher without losing control?
Of course, only Huawei can accomplish this task.
DJI, Huawei and Starlight Technology have jointly tackled the problem for more than two years and finally successfully developed a miniaturized information relay station.
Uh... Actually, it also draws on the principles of early warning aircraft, but can you say that?
It just so happens that DJI's flight formation program has been successfully developed, and it is now possible to add a relay station aircraft to a group of drones being released.
After reaching the limit of flight distance, let the relay station aircraft stay in the air and act as an information transmission intermediary, while other drones can continue to extend outward.
After testing, in this way, up to two sections of information relay can be used in the middle, which also allows the flying height of the fixed-wing drone to reach a gratifying 1,500 meters.
If you want fixed-wing drones to fly higher and farther, you need to wait for the improvement of the near-Earth communication satellite network and breakthroughs in drone engines, materials and other aspects.
But these achievements have already met Xiao Qian's expectations.
He left a message for Wang Tao.
"Before May, I must leave three thousand fixed-wing and rotary-wing drones for me. I will be of great use."
At the same time, he put forward new requirements for Wang Tao.
"During this period of time, you need to study how to use drones for tree felling operations. For example, equip drones with chainsaws or flamethrowers. Oh, by the way, there are also fire extinguishers."
Wang Tao's face turned green when he heard this. Why did this boss have such a weird idea?
