Although there have been many disagreements on the technical research and development of the 'Battlefield Sweeper' high-speed attack UAV, Yang Fan and Pang Yifei jointly launched the first engineering prototype of the high-speed attack UAV.

There are many reasons for this, not only because of the tight schedule, but also because it is too difficult to accurately identify and avoid obstacles in high-speed flight.

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

Of course, this is an exaggeration. But this technology is really difficult, and the difficulty is that it is fast.

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

Similarly, more equipment means heavier drone. And with limited power, the speed of the drone will also be slower. This also means that this drone will lose the suddenness of the enemy's attack, increasing the probability of enemy detection and interception.

However, if the volume and load are controlled, the equipment on it is very limited. This also means that the number of sensors of each type cannot be too large, the size cannot be too large, and the power cannot be larger.

The low power also restricts the detection distance, shortens the reaction time, and increases the difficulty of the drone to avoid obstacles.

Therefore, after the two teams fiddled with each other for more than ten days, Yang Fan's initiative to speak was immediately responded by Pang Yifei.

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

"This is the high-speed attack drone you developed?" Wu Hao looked at the black drone in front of him, which was the size of two palms of an adult, and frowned.

As the limited date is getting closer and closer, 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 the first complex terrain test, Wu Hao hurriedly rushed over.

But the drone in front of me was a little disappointed, with a diameter of more than forty centimeters, almost the same size as the civilian 'elves' on the market.

Because it is a test engineering machine, it is relatively rough, and there is no shell on the upper part of the fuselage, which is full of various components and messy wiring.

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." At that time, the volume will continue to shrink, and it will not be as large 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?" ”

Pang Yifei smiled at him and explained: "In our company's park, we have arranged an obstacle passage with a total length of more than 100 meters around the laboratory building.

We let the drone fly over the 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 the relevant facilities outside the laboratory building when he came, he didn't know what it was at first, but now he finally understood its true purpose.

"Is the whole process entirely of its own judgment flying?" Wu Hao thought for a while and asked.

Yang Fan nodded and said, "We are just planning the relevant flight routes, and the specific path is up to it to judge." ”

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

Pang Yifei nodded and said, "Okay, we're going to debug it finally, and it will be good soon." ”

As he spoke, he, Yang Fan and other technicians began to get busy with their own work. Although this is just a simple test, it can be seen that everyone is under a lot of pressure, and they can't help but be a little nervous when they are approaching the test.

After about twenty or thirty minutes of debugging, after seeing that all the data were normal, Yang Fan and Pang Yifei took the drone downstairs and came to the proposed test channel that had been built.

The entire passage surrounds the outer wall of the laboratory building in the shape of a '冂'. In addition to two sharp right-angle bends of 90 degrees, the passage is also arranged with various obstacles, including horizontal and vertical planks, some treetops, and other obstacles.

Therefore, the space that can be left for drones to pass through is actually very small, let alone drones, even if people cross in the passage, it takes a lot of effort.

In order to record the status of this test, in addition to the camera cameras on the drone, the project R&D team also arranged some GoPro cameras in the channel. In addition, several technicians stand in various corners with cameras in hand to ensure that the complete test process can be recorded from all angles, so that the scientific team can analyze and study the video footage.

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

"Are you ready?"

Hearing him shout, although Yang Fan was still a little hesitant, he finally nodded: "Okay!" ”

"Let's get started." Wu Hao waved his hand.

Yang Fan took a deep breath, and then nodded at Pang Yifei, who was standing next to him, to start. Pang Yifei glanced at the drone placed on the take-off frame, and then pressed the start switch.

Airplanes!

The drone jumped off the take-off frame in an instant, and then quickly flew towards the obstacle course. The drone's speed slowed down 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 channel, high and low, very flexible.

Airplanes......

The drone flew over from the corner in front of Wu Hao and them, which made Wu Hao and the others applaud when they saw this.

And Yang Fan, who had been staring at the monitoring screen, heard the sound, and his face also showed a smile. However, he still stared at the screen, not daring to slack off.

There had been so many failed tests in the past that they didn't want to have a painful experience again. For scientific research technicians, there is no one more frustrating than the failure of the project they are responsible for.

Many researchers even described: "The moment I failed, it was as if an invisible hand had taken all the strength out of me." I collapsed to the ground, and my colleague next to me tried to help me up, but I couldn't stand up, and my mind went blank. ”

Click, click, click!

Three consecutive sounds raised his heart to his throat.

This is the sound of the drone crashing against an obstacle, and although the drone continues to fly, the speed is significantly reduced a lot.

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

Pang Yifei stared at the screen, his face became solemn: "It's not clear now, and the reason can only be found when the test is over and the flight trajectory and monitoring screen are studied." ”

"Fly out!"

The technician next to him said excitedly!

Bang Bang Bang ...... The crowd watching the test also burst into applause.

Only Yang Fan and Pang Yifei stood in the crowd with bitter faces, looking at the obvious bump marks on the drone flying at reduced speed.
