Hugh!
With a long whistling sound, a large unmanned aircraft with a length of ten meters and a wingspan of twenty meters rushed into the sky like a sharp arrow. Soon there was only a black spot left, and then disappeared from Zhou Feiyu's sight.
Zhou Feiyu stared at the dark sky for a while, and then returned to the research room of the factory.
It can be said that the successful takeoff of the unmanned aircraft means that the unmanned aircraft is very successful in terms of design and manufacturer. The next step is to test the true performance of this unmanned aircraft.
In the research room, a huge screen is divided into two viewing angles. One shows a light point, which is constantly moving. The light point represents that it has flown into the sky.
Another perspective is the dark night, the sky full of clouds, and the dark world under the sky with a little light. This is an image transmitted back from an unmanned aircraft.
"Father, the flight is normal. It has risen to an altitude of 1,500 meters and the speed has reached 100 kilometers per hour..."
Artificial Intelligence The voice of "Galaxy" sounded, introducing the flight status of the unmanned aircraft.
Then, on the viewing angle screen displaying light spots, real-time parameter changes of the unmanned aircraft, including the body environment and the external environment, appeared simultaneously.
At a glance, it's clear.
However, at this time, Zhou Feiyu could only see these parameters and the images captured from the optical equipment mounted on the unmanned aircraft, but could not see the graceful posture of the unmanned aircraft flying in the air.
The dark night and the dark appearance of the unmanned aircraft all have protective covers on them, making them extremely difficult to detect.
Coupled with the specially selected cloudy weather tonight, it reduces the possibility of being discovered.
In this period, there are radars on the ground and satellites in the sky. If any aviation equipment flies into the sky, it will be easily discovered. Only at night, the chance of being discovered is greatly reduced.
There are three reasons. One is black cover-up. Needless to say, everyone knows this.
The second is that flying at night is very unsafe, whether it is a manned or unmanned aircraft. As a result, observers at night will relax their vigilance.
As for the third thing, people's minds are actually very tired at night. Even if they have slept well during the day, they will still feel sleepy or have difficulty concentrating at night. This is a biological instinct and cannot be changed by human will.
Of course, this is just an external factor. What really needs to be done is to strengthen one's own stealth capabilities.
Many people misunderstand the term "invisibility", thinking that being invisible to the naked eye is only called invisibility.
In fact, this greatly misunderstands stealth in the military field.
Stealth in the military field, one refers to the equipment being covered up or too high and too far, so that it cannot be observed by the naked eye, which is called stealth; the other is the most core stealth, which is not detected by radar and other detection equipment.
If it is not detected by detection equipment such as radar, it is an absorbing material or shielding material, which is a targeted defense against detection equipment such as radar.
Radar relies on emitting electromagnetic waves and measuring the echo pulses emitted by electromagnetic waves onto obstacles to lock on to targets. As long as the echo pulse is reduced or eliminated, and the probability of being detected by radar is reduced, this is stealth.
The Wave-Absorbing Coating on the unmanned aircraft is used for stealth.
Half an hour later, the speed of the light spot stabilized, and the flight attitude also stabilized, which meant that the flight of the unmanned aircraft entered a stable state.
Zhou Feiyu saw that among the parameters displayed in real time, the speed line showed 500 kilometers per hour, the altitude reached 11,000 meters, and the battery life reached 50 hours!
"This performance is good!"
Zhou Feiyu praised.
Compared with the benchmark MQ-9 Reaper and Rainbow Series, both flight speed and battery life have far exceeded them.
Whether it is MQ-9 Reaper or Rainbow Series, the maximum flight speed of MQ-9 Reaper is only 460 kilometers per hour, and the endurance is only about 20 hours; as for Rainbow Series, the maximum flight speed is only more than 300 kilometers per hour!
The battery life of Rainbow Series is very long, and it can fly continuously for two days and two nights, but it is not as abnormal as 50 hours, and it is also heavier than his drone.
Being heavier, you can carry more fuel and have a longer battery life.
Of course, that was the Death and Rainbow of the past. The latest models in the past two years have not been exposed yet. There may be more advanced ones, but Zhou Feiyu doesn't care.
"Test the ultimate altitude and ultimate flight speed!"
Half an hour later, Zhou Feiyu started the real test step.
"Received, the order has been sent!"
Artificial Intelligence "Xinghe" replied while sending the command.
Then, the flying speed and flying height of the light spot on the big screen changed again, and climbed rapidly.
After a while, the flying speed of the unmanned aircraft exceeded 600 kilometers per hour, 700 kilometers per hour, and finally stopped rising when it reached 800 kilometers per hour.
At the same time, the flying altitude of unmanned aircraft has also reached 23,000 kilometers, which is almost the height of the restricted area for most aircraft. Most aircraft cannot fly this high because their performance does not allow it.
Of course, this height is actually nothing for high-performance aircraft such as fighter jets. Many domestic and foreign fighter jets can exceed 20,000 in a casual flight. There are 27,800 large aircraft types, some of which have even flown over 30,000 kilometers.
There are some unmanned aircraft that can fly this high, but it's not necessary.
Whether it is MQ Reaper or Rainbow Series, their cruising altitude is generally around 10,000 kilometers.
After flying for a while, the extreme test was completed, and Artificial Intelligence "Galaxy" sent a command to lower the altitude and flight speed of the unmanned aircraft and start cruising.
At this time, the cruising speed of the unmanned aircraft reached 650 kilometers per hour, and the cruising altitude was 15,000 kilometers.
This speed is only half the speed of sound.
It can be said that today, when various supersonic missiles are launched one after another, this speed actually has no advantage.
Zhou Feiyu also somewhat understands why the opposite MQ Reaper and Predator and other unmanned aircraft have not been updated for several years. Some senior military officials even openly stated in interviews with the media that unmanned aircraft have no advantage and do not rule out the possibility of being completely removed from the military.
"Let's call this drone Experiment No. 1."
Zhou Feiyu said to Artificial Intelligence "Xinghe", and then tested for about two hours. After comprehensively testing the performance, Xinghe commanded the drone to return home.
Tonight's test was still very successful. Looking at these data, Zhou Feiyu believes that the design goal was achieved.
The next step is to wait for the unmanned aircraft to return, and after comprehensively checking the condition of the aircraft body, enter the next step of optimization and improvement work, and strive to improve the test aircraft to a higher level.
Before the descent, the picture returned by the drone was a navy blue sky and a pitch-black ground, which was daunting.
The night sky is quiet.
"Hey, did something fly down just now?"
Outside the mountain, a young man who had just returned from playing cards at a neighbor's house was peeing towards the roadside, looking at the sky. Suddenly he felt something flying down from the sky, and disappeared in the blink of an eye.
After trembling, the young man rubbed his eyes, smiled and shook his head, "I must be dazzled."
