The first test flight could only be regarded as a small test, and there was no further test flight and test.

After the completion of the test flight, we analyzed a series of data, some areas that need to be improved and perfected, and implemented them one by one, and the follow-up, the aircraft will also carry out a series of test flight tests.

No, after the first test flight, about a little more than a week. The plane is ready to take off again, and this time it takes off, which is slightly different from the last time, because this time it can be said that experts gathered, and almost all of the relevant experts involved in the research and development of the "Black Ghost" UAV came to Tianfeng Technology Company.

"Lao Ding, you come too, haha."

"Lao Li, you're here too!"

“……”

A group of experts met, are a happy face, a warm greetings, in the reception room, can be described as very lively, after the greetings, everyone talked about some topics of the "black ghost" drone.

"The drone has completed its first test flight, Lao Zhang, I heard that the infrared sensing system you developed performed well in the first test flight!"

"Lao Zhao, you are the same, the synthetic aperture radar you developed is also very good!"

“……”

Everyone was chatting, Liu Wei walked in and said politely: "Experts, please move to the No. 1 conference room, our Mr. Li is already waiting for you in the conference room." ”

After speaking, Liu Wei personally led everyone into the No. 1 conference room, where a group of senior executives of Tianfeng Technology Company and several representatives of the military were already sitting.

Seeing everyone come in, Li Tianfeng got up politely, and then ordered everyone to sit down, and in the conference room, the projector had been turned on.

Li Tianfeng said: "Experts. Welcome to Tianfeng Technology Company again, today, our UAV will be tested again, before the test flight, I would like to inform you about the first test flight. ”

The first thing Li Tianfeng shared with you was a video of the drone taking off. Fly high in the air and then cruise at an altitude of 20,000 meters, as well as some ground conditions from the drone and much more.

After watching this video, Li Tianfeng said: "The first test flight, our drone performed relatively well, and there were only some small problems, which we improved one by one." ”

The screen of the projector turned, and a list was displayed in front of everyone. The list of some problems in the first test flight, these problems, Tianfeng Technology Company has collected and sorted out, and also improved and perfected them one by one, and Li Tianfeng informed everyone of the problems.

Then, Li Tianfeng said: "Today, everyone gathers at Tianfeng Technology Company, and we have a common goal, that is, our 'Black Ghost' drone. Today, we have specially chosen a rainy day. It is to further validate our drones. ”

Today's test flight verification is more in-depth and comprehensive than the first time, and most of the airborne equipment will be verified, and everyone is an expert responsible for the research and development of various airborne equipment, so they were invited to Tianfeng Technology Company.

At the meeting, Li Tianfeng told everyone about the contents of today's test flight. Then, Li Tianfeng got up and said: "Let's go to the UAV operation control center now and take a look at the test flight of our UAV."

It didn't take long for everyone to arrive at the operation control center. In the control center, everyone looks through the glass. Seeing the drone that had been parked on the runway in the distance, the weather outside was relatively gloomy, it was raining lightly, and there was even a faint sound of thunder in the sky.

Someone said worriedly: "Mr. Li, can our drone take off in such weather?" ”

Li Tianfeng said: "There is no problem, our 'Black Ghost' drone is all-weather, not affected and restricted by weather conditions." ”

As the deputy chief designer of the drone, Lei Yong ran over and said: "Boss, everything is ready, you can take off!" ”

Li Tianfeng nodded, waved his hand, and said: "Take off immediately, and carry out test flight verification according to the plan!" ”

The operator of the drone is still the personnel of Tianfeng Technology Company, and the military personnel are learning on the side, but even if they are replaced by military personnel, everyone can be competent.

The engine starts, and the "Black Ghost" begins to accelerate on the runway, take off, fly into the sky, pass through the clouds, and even faintly thunder is heard in the clouds.

Li Tianfeng behaved calmly, and the drone was designed with this situation in mind, even if it was hit by lightning, there would be no problems.

Through the navigation system, we through the screen, the flight altitude, speed, azimuth and other clear air, the drone successfully flew to an altitude of 20,000 meters, however, the drone is still continuing to climb, this time the first test is the maximum ceiling of the drone.

The maximum ceiling, this is a test of the engine, Sun Xiaoping looked at the huge display screen in the control room, his face was not shocked.

Twenty-one thousand, twenty-two thousand, twenty-three thousand, twenty-four thousand......

The plane climbed all the way, the flight altitude became higher and higher, until it climbed to an altitude of more than 28,000 meters before it stopped climbing, many experts are knowledgeable people, seeing this flight altitude, the heart was slightly surprised, such an altitude, the vast majority of the world's fighters are beyond the reach of the dust.

In other words, if the "Black Ghost" UAV is intercepted by fighters of other countries, it can fly at an altitude of 20,000 kilometers and escape from the interception of fighters. However, this is very unlikely to happen, because the drone's so-called "black ghost" is so easy to spot.

Sun Xiaoping saw this flight altitude, and breathed a long sigh of relief in his heart, this altitude has completely reached the design ceiling, indicating that the high-altitude performance of the turbofan 21B is very good.

This altitude also greatly exceeds the maximum flight altitude of the American "Global Hawk" UAV, which is already far ahead of the Global Hawk in this regard.

The altitude of more than 28,000 meters is enough to be proud of the others, no drone can surpass this height, who can fly higher than me?

After completing the maximum ceiling test, the flight altitude began to decrease, because the camera equipment was turned on and the synchronous image transmission was carried out, and everyone could see clearly that under the drone, there were very thick clouds, and it was still dark clouds, and it was completely impossible to see the situation on the ground.

However, as soon as the image turned, the reconnaissance equipment was switched, and through these clouds, the situation on the ground was clearly seen, and at present, the drone was still at an altitude of 20,000 meters.

"It's so clear, it's completely clear!"

"yes, there's a clear view of what's going on on the ground!"

The experts all looked happy, and it can be seen that the camera equipment has been developed very successfully, whether it is optoelectronic equipment or infrared sensing equipment.

"The parameters are displayed normally!"

"Achieve the design effect requirements!"

“……”

The loud voices kept coming, and many of the experts were happy, and the sense of accomplishment in their hearts was simply strong.

The "Black Ghost" UAV, after the last test flight, has been slightly improved and perfected, and this test flight has performed even more perfectly.

After cruising at an altitude of 20,000 meters, the altitude of the plane was further reduced, and everyone saw that the flight altitude of the plane dropped to an altitude of 7,500 meters.

Hover!

This word flashed in the minds of many people, and everyone soon knew what was going on, even those representatives of the military also knew that the "Black Ghost" drone was hovering at an altitude of 7,500 meters.

This is also the maximum hovering altitude of the "Black Ghost" UAV, after the aircraft hovers, it begins to take pictures of the ground, and one by one high-definition photos are transmitted to the control and command center through data transmission.

Obviously, hovering to take pictures, the image is clearer, and even, everyone can see that on a certain photo, an old man wearing a hat and fishing in the rain appeared, and it was relatively clear.

The representatives of the military, seeing such a photo, were inexplicably excited, it was amazing, it was beyond everyone's imagination.

After a series of tests to fully verify the performance of the on-board camera and camera equipment, the "Black Ghost" drone began to cruise at an altitude of 20,000 meters and fly into the distance.

Deep in a certain mountain, here is a certain large array-controlled radar station of the military, monitoring everything within a radius of thousands of kilometers.

The radar closely monitored everything, and Comrade Major General looked at the time, and then couldn't help asking: "How is it?" What did you find? ”

A colonel next to him said, "Chief, nothing has been found, everything is normal." ”

The major general thought in his heart, the drone should still not appear in the radar range, wait a little longer, the time passed minute by minute, and after more than half an hour, the major general couldn't help but ask again: "How is it?" What did you find? ”

The colonel still said: "Chief, everything is normal, nothing has been found. ”

The major general said: "Is it that the plane has passed?" ”

The colonel said confidently: "Impossible, this is a large radar, exaggeratedly, even a bird will not want to escape our eyes." ”

The major general was a little relieved, waited for a while, and felt slightly wrong, at this time, the phone rang, and the phone said: "The target has flown past your defense area and is flying towards the second area." ”

"Ahh It's already passed, not only the major general, but also the colonel next to him, and how radar soldiers are all stunned, and everyone said in their hearts, this, this is impossible!

The "Black Ghost" drone had indeed flown directly above the radar station half an hour ago, and at an altitude of 20,000 meters, it transmitted a clear photo of the radar station back to the control center of Tianfeng Technology Company.

This is the stealth performance test of the "Black Ghost" UAV, and the military cooperated with this test to know the flight path of the UAV, and prepare early, with the radar fully turned on and closely monitored.

The "Black Ghost" drone flew thousands of kilometers all the way, even flying out of the border, and along the way, none of the radars detected the whereabouts of the drone.

If there is anything to be found, only when flying through the No. 5 area, there is the largest and latest super radar in our country, and a little abnormality was found here, but the radar signal was not obvious, and the radar operator was negligent for a while, and the "Black Ghost" drone easily passed through the No. 5 area.

Today's three watches, the second one is sent! (To be continued......)
