Ge Changhai, Tian Weidong and Zhong Bai all started knocking on the table at the same time, appearing very excited.
After the altitude test was completed, Xu Jianguo did not immediately control the drone to land, but kept the altitude at 1,500 meters and began testing its wind resistance.
Because of the addition of an external magazine, the maximum take-off weight has reached the theoretical value, so there is no need for separate testing.
The data transmitted back by the wind speed sensor at this time showed that the wind speed at an altitude of 1,500 meters reached 12 meters per second, 43 kilometers per hour, which is equivalent to a level 6 strong wind day on the ground.
However, despite this, the images transmitted back by the drone's camera did not show any significant shaking. In other words, the wind resistance test of UAV No. 001 has met the theoretical requirements.
Xu Jianguo looked at the data on the monitor and nodded with satisfaction, while Liu Mingyu and the other two standing beside him clenched their fists and waved them vigorously.
Before starting the test, what they were most worried about was the drone's wind resistance. The theoretical value designed by Xu Jianguo was actually only a level 6 wind. This was the conclusion he came to after referring to the drone's altitude limit, meteorological data over the years, and Xu Shisi's computer simulation.
Unexpectedly, the situation encountered by the drone after it rose to an altitude of 1,500 meters was exactly like this. It directly reached the theoretical limit. No wonder they became nervous.
Now the first phase of flight control testing of UAV No. 001 has been completed for the most part, with only the final speed test remaining.
"Mr. Xu, can we start the speed test now?" Liu Mingyu asked.
Xu Jianguo nodded and said, "Well, we can start now, but wait a moment, until I solve this little problem!"
Several people were stunned and looked at each other, not understanding what the little trouble Xu Jianguo was referring to.
When they looked at Xu Jianguo again, they found that he had stood up, his eyes fixed on the monitor. When Liu Mingyu and others also looked at the monitor, they found that several black dots had suddenly appeared on the screen and were rapidly approaching the airspace where the drone was.
"Report, migratory birds have been spotted in the northeast direction, please be careful to avoid them!" At this time, a voice suddenly came from the walkie-talkie placed nearby. This was a message from the soldier responsible for monitoring the airspace.
"Got it, continue monitoring!" Liu Mingyu walked over quickly, picked up the walkie-talkie and said.
As Xu Jianguo turned a ring on the remote control, the camera's zoom function started working and the black dots on the monitor gradually became clearer.
"Wild geese?"
Zhao Huanbin on the side spoke first.
"Well, that should be right. I often saw them in my hometown when I was a child. Counting the days, it is indeed the day for them to migrate." Jin Hao nodded.
Xu Jianguo smiled without saying anything. After resetting the zoom function, he began to control the lateral movement of the drone, trying to avoid the flight path of the geese.
The reason why he chose to move sideways instead of descending was that he hoped to make use of the drone's extremely fast directional change performance in such an emergency situation.
At this time, Ge Changhai and others were no longer satisfied with continuing to stare at the monitor. Instead, they picked up the telescopes on the table, walked out of the observation area, and looked up at the sky.
According to the theoretical values designed by Xu Jianguo, the forward flight speed of the Tianfa attack drone can reach 43 meters per second, while the lateral and backward flight speeds can reach 39 meters per second.
So when Xu Jianguo moved the horizontal joystick on the remote control, the drone, which was originally hovering at an altitude of 1,500 meters, immediately responded and flew quickly to the west.
Just over ten seconds after the drone flew sideways, a group of geese arranged in a V-formation flew past quickly, and everyone breathed a sigh of relief.
After Xu Jianguo controlled the drone to avoid the geese, an idea came to his mind. He planned to try to install a micro radar system on the drone based on the existing one.
After all, the camera of the Tianfa drone can only see in one direction. Today, it was because of good luck that this group of geese was captured by the camera, and there were also people on the scene monitoring the airspace.
What if it is deployed on the battlefield in the future? The operator alone will not be able to take into account the blind spots in the other three directions. Once other flying objects appear in the air, a collision is likely to occur.
Moreover, with the addition of radar systems, the application areas of drones will be further expanded, and the advantages outweigh the disadvantages no matter how you look at it.
However, if a radar system is added, the weight of the drone will inevitably increase, which will directly affect the drone's payload capacity and thus weaken its attack performance.
Xu Jianguo simply went over it in his mind and stopped thinking about it. As for how to make changes later, he had to go back and think about it carefully. If it really didn't work, it would not be impossible to throw this problem to Xu Shisi.
After determining the next target, Xu Jianguo did not delay any longer and began to move the joystick to test the maximum flight speed of the drone.
After more than ten minutes, the drone's flight speed test ended and all values reached the designed theoretical values.
At this point, the first phase of flight control testing of UAV No. 001 has been completed. Xu Jianguo also controlled the UAV to descend to an altitude of 500 meters. The next step will be the second phase of machine gun attack power testing.
At the farthest end of the test site, on the gentle slope of a hill, more than a dozen scattered targets and a huge circular target with a diameter of five meters have been arranged.
