Military Technology

Although there were many differences in the technical research and 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, there is also the fact that it is too difficult to accurately identify and avoid obstacles during high-speed flight.

In Pang Yifei's words, this is ten times more difficult than the current unmanned driving technology.

Of course, this is an exaggeration. But this technology is really difficult, and the difficulty lies in its speed.

First of all, the limited volume and load limit the equipment that can be carried on the UAV. The more equipment, the larger the size of the drone, which means that it is more inconvenient to carry and the probability of being discovered and intercepted by the enemy is higher.

Likewise, more equipment means heavier drones. And under limited power, the speed of the drone will be slower. This also means that this UAV will lose the suddenness of the enemy's attack, increasing the probability of the enemy's discovery and interception.

But if the size and load are controlled, the equipment on it will be very limited. This also means that the number of various sensors cannot be too large, the size cannot be too large, and the power cannot be greater.

The low power also restricts its detection distance, shortens the reaction time, and increases the difficulty for the UAV 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 immediately got a response from Pang Yifei.

Immediately, the two teams merged together to learn from each other's advantages, which led to staged progress in technical research in this area.

"This is the high-speed attack drone you developed?" Wu Hao frowned as he looked at the black drone that was the size of two adult palms.

As the limited date draws closer, Wu Hao has been paying close attention to the research progress of this project. Hearing that the project has made staged progress and that the first complex terrain test is about to be conducted, Wu Hao hurried over.

But the drone in front of me was a bit disappointed, with a diameter of more than forty centimeters, which was about the same size as the civilian 'Spirits' on the market.

Because it is a test engineering machine, it is relatively rough. There is no shell on the fuselage, and there are various components and messy circuits 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, further optimization is required. At that time, the volume will continue to shrink, and it is impossible to be as large as it is now. "

Wu Hao nodded when he heard the words, and while looking at the engineering prototype in front of him, he asked, "How to test?"

Pang Yifei smiled at him and explained: "We have arranged an obstacle course with a total length of more than 100 meters around the laboratory building in our company park.

We let the drone fly over this obstacle line to see if it can successfully cross it, and how long it takes in total. "

Wu Hao nodded when he heard the words. He did see related facilities outside the laboratory building when he came. He didn't know what it was at first, but now he finally understands its real purpose.

"Is it completely judging the flight in the whole process?" Wu Hao asked after thinking about it.

Yang Fan nodded and said: "We are just planning the relevant flight routes, and the specific routes are determined by itself."

Hearing Yang Fan's words, he finally showed a smile, then waved his hand and said, "Then let's start."

Pang Yifei nodded and said: "Okay, we are finally going to debug it, and it will be ready soon."

With that said, he, Yang Fan and other technicians started to work on their own. Although this is just a simple test, it can be seen that everyone is under a lot of pressure. As the test is approaching, it is unavoidable to be a little nervous.

It took about 20 to 30 minutes to debug. After seeing that all the data were normal, Yang Fan and Pang Yifei took the drone downstairs and came to the suggested test channel that had been built.

The entire passage surrounds the outer wall of the experimental building, forming the shape of a '冂'. In addition to the two 90-degree sharp right-angle bends, there are also various obstacles in the passage, including wooden planks in disorder, some treetops, and other obstacles.

Therefore, there is actually very little space for drones to pass through. Let alone drones, even people need to spend a lot of effort to pass through the passage.

In order to record the test status, in addition to the camera 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 and standing in every corner to make sure that the complete test process can be recorded from all angles, so that the scientific research team can analyze and research through these video materials.

Wu Hao found a better viewing position at the corner, and then shouted at Yang Fan who was still making preparations over there.

"Are you ready?"

Hearing his words, although Yang Fan still hesitated, he finally nodded: "Okay!"

"Let's start then." Wu Hao waved his hand.

Yang Fan took a deep breath, then nodded to Pang Yifei who was standing beside him to signal to start. Pang Yifei glanced at the drone on the takeoff stand, and then pressed the start switch.

hum!

The drone instantly jumped from the takeoff stand, and then quickly flew towards the obstacle course. The speed of the drone dropped significantly when it came into contact with the obstacle passage, but it was still very fast.

I saw that the drone began to dodge left and right in the obstacle passage, sweeping higher and lower, very flexible.

hum...

The drone flew over from 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 monitor screen, also smiled when he heard the sound. But he still stared at the screen, not daring to slack off.

They have failed the test too many times before, and they don't want to have another painful experience this time. For scientific research and technical personnel, there is nothing more frustrating than the failure of the project test they are responsible for.

Many researchers even described: "At the moment of failure, it seemed that an invisible hand took away all the strength from my body. I collapsed to the ground at once, and the colleagues next to me tried to help me up, but I couldn't stand up, my mind went blank."

Tap, tap, tap!

Three consecutive beeps raised his heart to his throat.

This is the sound of the drone bumping into an obstacle. Although the drone is still flying, its speed has obviously decreased a lot.

"What's going on?" Yang Fanlai asked.

Pang Yifei stared at the screen, his face serious: "It's not clear yet, the reason can only be found after the test is over and the flight trajectory and monitoring screen are studied."

"Fly out!"

The technician next to him said excitedly!

Clap, clap... Everyone who was watching the test burst into applause.

Only Yang Fan and Pang Yifei stood in the crowd with bitter faces, watching the obvious bump marks on the drone flying over at a slow speed.
