"Let's take a look at the take-off data first, if it is feasible, conduct a landing test, and in other tests, such as the air refueling you said, we have to contact the air tanker first, and it will definitely be difficult to get it all of a sudden."

Huang Lao and Li Lao thought about it for a while, and then looked at each other before saying their suggestions. It's all there

"The tanker is easy to do, the 81st Division has a tanker, and they also have related training programs, so it's no problem to come to training temporarily."

Yang Haisheng sat with the two old men, and after listening to their words, he immediately said that the tanker was easy to handle.

"Okay, that's it."

In this way, it also saved Huang Lao and them from contacting the tanker temporarily, so they decided to do other tests first, and then carry out these difficult tests such as empty refueling.

With this decision, this test was very different from the previous plan, and the first flight test turned into a comprehensive test experiment of the whole machine.

Please ask Yang Haisheng to contact Commander Lin of the 81st Division, and Xu Ziling returned to his seat.

"Attention all units, 'Shadow Dragon One' will enter the degree test immediately."

A command spread in the communication system, and both in the control heart and the staff outside the field all acted quickly.

"Ready!"

After waiting for less than a minute, Xu Ziling received a report that the test could be carried out.

"Four-kilometer supersonic cruise!"

Hearing the report, he spit out a command in his mouth, put his hand on the drone control terminal, let go of the drone's slow cruise, and entered the manual control.

Taking over the manual control, his hand moved, the altitude remained the same, not to consider the overload, and controlled the plane to add up suddenly, so that the plane immediately entered the supersonic flight.

On the big screen, a sonic boom suddenly appeared at the tail of "Shadow Dragon One", and the degree began to increase greatly.

"Mach 1. Normal. ”

With the addition of the drone, the staff also immediately reported its degree.

"Mach 1.5. Normal. ”

"Mach 2. Normal. ”

"Mach 2.5. Normal. ”

"Mach 3. Normal. ”

Xu Ziling has been controlling the drone in addition, and the report of the staff has not stopped.

"Mach 3.5. Normal. ”

"Mach 4. There is a shake in the fuselage. ”

While controlling the drone, Xu Ziling has also been paying attention to the data of the aircraft, and without waiting for the report to sound, he also saw the shaking on the picture from the drone on the control terminal screen, and also knew that at this altitude, the degree of Mach 4 was almost to the limit.

So the hand stopped adding the action at the same time, but controlled the plane minus.

"Mach 3.9 is flying normally."

"The signal transmission of the reconnaissance equipment is normal, and the picture is synchronized and clear."

"Mach 3.9 flies 5 kilometers normally."

"The signal transmission of the reconnaissance equipment is normal, and the picture is synchronized and clear."

At an altitude of four thousand meters, controlling the drone to fly smoothly for ten kilometers, Xu Ziling felt the need to conduct a new altitude test.

"Prepare for the 8,000-meter altitude flight test."

New instructions were given, and the staff immediately began to save the data and began to prepare for a new round of testing.

When everything was ready, Xu Ziling, who was controlling the drone, began to climb with the "Shadow Dragon No. 1".

Just at an altitude of 8,000 meters, the drone stopped moving upwards and began to maintain altitude, and new tests began.

The degree of the aircraft itself is very fast, so the test is also very fast, and it will not be long before the test is completed at an altitude of 8,000 meters.

After this altitude, we tested the altitude of 12,000 meters, 20,000 meters, and 24,000 meters.

Finally, it was concluded that between 8,000 and 20,000 meters, the UAV can reach a maximum of Mach 5 degrees, and if it is higher, it has to be reduced due to incomplete fuel combustion caused by the atmosphere, but when testing 24,000 meters, the "Shadow Dragon" 1 can also reach Mach 4, which is much faster than the highest reconnaissance aircraft today, which makes everyone very excited.

For such a result, even if the lion had said it before, after seeing it with his own eyes, Xu Ziling was as excited as everyone else, if it wasn't for the fact that he was testing it now, he really wanted to look up to the sky and laugh.

"Test the limit altitude."

After calming down his excitement, he spat out another command.

At an altitude of 24,000 meters, even if it is a relatively best high-altitude reconnaissance plane, this altitude is quite good, but Xu Ziling is still a little dissatisfied, and he also wants to see what limit altitude the "Shadow Dragon" can fly to, so there is such a test that was not planned for the plan.

Others have been shocked by the previous tests, and they are also very interested in this extreme height, listening to Xu Ziling say this, they should be busy again, and they also focused their attention and watched on the big screen.

"25,000 meters, normal flight."

"26,000 meters, flight normal."

“……”

"35,000 meters, normal flight."

"36,000 meters, normal flight."

"36100 meters, normal flight."

"At 36,200 meters, the data of the power part is abnormal, the analysis of oxygen supply is insufficient, and the combustion is incomplete."

The drone was getting higher and higher, and when it reached the altitude of 36,200 meters, the news of the abnormality finally came.

Hearing this report, Xu Ziling immediately stopped climbing and began to pull down.

"I don't get along much with what I expected!"

In his mind, Xu Ziling said to the lion.

"Of course, originally this plane paid attention to stealth ability, not flight altitude, and it was okay to have this flight altitude, even if it was swaggering and flying over others, they didn't have this missile to hit it."

The lion has also been paying attention to this test, and quickly responded to Xu Ziling's words.

"That's right."

Stealth unmanned attack aircraft, although it is said to be an attack aircraft, is actually a dual-purpose attack and reconnaissance aircraft.

At the same time as testing the flight altitude, they also tested the reconnaissance equipment above, whether it was in a few kilometers or the highest flight altitude, Xu Ziling just glanced at it, and saw that the photos sent back were extremely clear, even a little better than high-definition low-orbit satellites.

When using UAV reconnaissance, that is to say, it can fly at an altitude of 35,000 kilometers, not to mention the stealth function of the UAV itself, there is no stealth ability at this altitude, with the most advanced anti-aircraft missiles today, it is estimated that the aircraft that can fly at this altitude is enough.

Not to mention those fighters or interceptors, because as soon as the plane is dispatched, the drone will already be able to detect the other party, at an altitude of 20,000 meters below the Mach 5 degree, Xu Ziling believes that even the most advanced F-35 in the United States is just a scum in front of it.

"Let's test the stealth function quickly, I haven't seen this thing before, I wonder if I can scan it after the invisibility?"

One of the most advanced and sci-fi colors of the "Shadow Dragon" is its stealth technique, because it has a layer of nano stealth material coating on the outside of its fuselage, which can make the aircraft really disappear from people's sight under the charging reaction of this layer of material.

Although the technique is from the lion's system, he has never seen this before, and he really doesn't know if he can still scan it under this stealth state.

I had been testing other functions before, but at this time, the lion couldn't help it, so he mentioned it to Xu Ziling.

Xu Ziling is also looking forward to this, after all, such techniques are only limited to those sci-fi blockbusters.

Listening to the lion mention, he also became interested.

"Okay, I'll be back in time."

The drone tests multiple levels of altitude has always been carried out in a line, and now the relevant tests have been carried out to the point that only this stealth function remains, so it is better to be on the way back.

When he descended to an altitude of 12,000 meters, he began to turn back with his drone.

At the same time, a new test instruction was issued to all the staff:

"Start the return home, prepare to test the stealth system, all departments pay attention."

Hearing this, everyone immediately boiled.

Stealth is the most important thing of the "Shadow Dragon", not to mention this kind of unbelievable, can really disappear from the sight of the technique, once successful, it is a historical precedent, can be remembered by the world for a lifetime, such a major event, how can you not pay attention to it?

So as soon as his words came out, whether it was the staff or Huang Lao, who was sitting and watching, they were all extremely excited.

"The test time is ten minutes, and it will start in ten minutes, and all radar observation departments will pay attention."

Looking at those excited staff, Xu Ziling didn't say anything, after all, even he himself was like this, and he could understand their mood, smiled, and issued the order again.

When the test reached the highest of Mach 5 many times, the drone at this time had already flown out of the range of Xinghai Province, and the degree of return did not increase to the maximum, and it would take a while to come back.

After calculating, Xu Ziling was ready to start the test in ten minutes, because at that time, the plane would be within the range of Xinghai Province, and the relevant observation radar stations would be able to observe it at any time.

Nine minutes!

Eight minutes!

Seven minutes!

With the countdown of time, the hall that was still lively just now became silent, and one by one they were either looking intently at the instrument in front of them, or staring at the big screen showing satellite images.

One minute!

Thirty seconds after the last!

Ten!

Nine!

Eight!

……

Two!

One!

"Start!"

When the countdown reached one, Xu Ziling pressed the button of the drone's stealth on the control terminal.

As soon as the "shadow dragon" on the screen finished his words, the surface of the drone immediately began to notice that there was a distortion of light.

Then the dark gray sè of the fuselage also began to be transparent, as if it had become an empty cloud of water.

The transparency became higher and higher, and after five seconds, the distorted water mass flashed, suddenly disappeared, completely disappeared from everyone's sight, and the satellite screen also became a blue sky and white clouds, as if the "shadow dragon" that existed a few seconds ago had never appeared in the picture.

"Boom!"

Seeing this, all the personnel stood up and looked at the big screen in disbelief.
