Although there were many differences in the technical development of the 'Battlefield Sweeper' high-speed attack drone, Yang Fan and Pang Yifei jointly launched the first engineering prototype of the high-speed attack drone.
There are many reasons for this. In addition to the tight time, it is also too difficult to accurately identify and avoid obstacles during high-speed flight.
In Pang Yifei’s words, this is more than ten times more difficult than current driverless technology.
Of course, this is an exaggeration. But this technology is really difficult. The difficulty lies in its speed.
First of all, the limited volume and load limit the equipment that can be carried on this drone. The more equipment there is, the larger the drone will be, which means it will be more inconvenient to carry and the higher the probability of being discovered and intercepted by the enemy.
Likewise, more equipment means the drone weighs more. And with limited power, the speed of the drone becomes slower. This also means that this drone will lose the surprise of attacking the enemy and increase the probability of enemy discovery and interception.
But if the volume and load are controlled, the equipment mounted on it will be very limited. This also means that the number of various types of sensors cannot be too large, the size cannot be too large, and the power cannot be greater.
The low power limits its detection distance, shortens the reaction time, and increases the difficulty for the drone to avoid obstacles.
Therefore, after the two teams fiddled with each other for more than ten days, Yang Fan finally took the initiative to speak and received an immediate response from Pang Yifei.
Immediately, the two teams merged together and absorbed each other's advantages, which led to phased progress in technical research in this area.
"Is this the high-speed attack drone you developed?" Wu Hao frowned as he looked at the black drone in front of him, which was as big as two adult hands.
As the deadline approaches, Wu Hao has been paying close attention to the research progress of this project. After hearing that the project had made phased progress and was about to conduct its first complex terrain test, Wu Hao hurried over.
But the drone in front of me was a bit disappointing. It was more than forty centimeters in diameter, almost the same size as the civilian 'Elf' on the market.
Because it is a test engineering machine, it is relatively rough. There is no casing on the body, and there are various components and messy lines inside.
Seeing the disappointment on Wu Hao's face, Yang Fan said with a smile: "This is just our engineering prototype. If the test is successful, it will be further optimized. The size will continue to shrink by then, and it will not be as big as it is now. .”
Wu Hao nodded when he heard this, and while looking at the engineering prototype in front of him, he asked: "How to test it?"
Pang Yifei smiled at him and explained: "In our company campus, we have arranged an obstacle course with a total length of more than one hundred meters around the laboratory building.
We let the drone fly over this obstacle course to see if it can successfully cross it and how long it will take in total. "
Wu Hao nodded when he heard this. He did see related facilities outside the laboratory building when he came. He didn't know what they were at first, but now he finally understands their true purpose.
"Is it completely autonomous in the whole process?" Wu Hao thought for a moment and asked.
Yang Fan nodded and said: "We are just planning the relevant flight route, and it will judge the specific path by itself."
Hearing Yang Fan's words, he finally showed a smile, then waved his hand and said: "Then let's get started."
Pang Yifei nodded and said: "Okay, we are going to do some final debugging. It will be fine soon."
As he said that, he, Yang Fan and other technicians began to work separately. Although this is just a simple test, it can be seen that everyone is under a lot of pressure. As the test approaches, I can't help but feel a little nervous.
It took about twenty or thirty minutes to debug. After seeing that all the data were normal, Yang Fan and Pang Yifei took the drone downstairs and came to the built suggestion test channel.
The entire passage surrounds the outer wall of the experimental building and forms a "冂" shape. In addition to two 90-degree sharp right-angle bends, various obstacles are also arranged in the passage, including horizontal and vertical wooden boards, some treetops and other various obstacles.
Therefore, the space left for drones to pass through is actually very small. Let alone drones, even people need to spend a lot of effort to cross the passage.
In order to record the test status, in addition to the cameras on the drone, the project research and development team also arranged some GoPro cameras in the channel. In addition, there are several technicians holding cameras standing in various corners to take pictures, ensuring that the complete test process can be recorded from all angles, so that the scientific research team can conduct analysis and research through these video data.
Wu Hao found a better viewing position at the corner, and then shouted to Yang Fan who was still making preparations over there.
"Are you ready?"
Hearing his call, although Yang Fan was still a little hesitant, he finally nodded: "Okay!"
"Then let's get started." Wu Hao waved his hand.
Yang Fan took a deep breath, and then nodded to Pang Yifei standing next to him to start. Pang Yifei glanced at the drone placed on the take-off stand, and then pressed the start switch.
Buzz!
The drone instantly jumped up from the take-off stand and then quickly flew towards the obstacle course. The drone's speed dropped significantly when it came into contact with the obstacle course, but it was still very fast.
I saw the drone starting to dodge left and right in the obstacle passage, flying higher and lower, very flexible.
Buzz…
The drone turned and flew around the corner in front of Wu Hao and the others, which made Wu Hao and the others applaud.
Yang Fan, who had been staring at the surveillance screen, smiled when he heard the sound. However, he still stared at the screen, not daring to slack off.
Tests had failed too many times before, and they didn't want to have another painful experience this time. For scientific research and technical personnel, there is nothing more frustrating than the failure of a project test that they are responsible for.
Many scientific researchers even described: "The moment I failed, it was as if an invisible hand took away all the strength from my body. I collapsed to the ground, and the colleagues next to me tried hard to help me up, but I couldn’t stand up and my mind went blank.”
Ta, ta, ta!
Three consecutive sounds raised his heart to his throat.
This is the sound of the drone hitting an obstacle. Although the drone continues to fly, its speed has obviously dropped a lot.
"What's going on?" Yang Fanlai asked.
Pang Yifei stared at the screen with a serious look on his face: "It's not clear yet. The reason can only be found after the test is completed and the flight trajectory and monitoring images are studied."
"Flying out!"
The technician next to him said excitedly!
Bang bang bang... everyone watching the test also burst into warm applause.
Only Yang Fan and Pang Yifei stood in the crowd with grim faces, looking at the obvious collision marks on the drone that was flying over at a reduced speed.
