It is no wonder that the officers and soldiers around them will be like this, nine thousand meters, which is far more than the five thousand meters of altitude they usually train.

That's it, at such an altitude, the oxygen content in the air has decreased sharply, which is a severe test for the power of the aircraft, not to mention anything else, the J-6 and J-7 equipped by their troops, not to mention the afterburner, is the normal cruise is cautious, no way, the condition of the aircraft is too worrying, in case something happens, it will be difficult to do.

It stands to reason that the equipment of the troops should be very good, and even they dare not rush to this height, how can it not be surprising that an aviation model of unknown origin actually rushed up.

So people on both sides of the runway began to talk about how long the drone on it could last? 30 seconds, or two minutes?

You must know that the drone uses a twin-cylinder gasoline engine, whether it is power output or fuel conditions, it is far worse than jet power, and it relies more on combustible gases such as oxygen, so under normal circumstances, the aircraft with this kind of power at high altitude will not last long.

This is also the reason why the model aircraft of the sports system can fly to an altitude of 5,000 meters, which is already a record-breaking, not because it is not high, but because the power of the power unit drops sharply above the altitude, which is not enough to support the aircraft to continue to rise.

They are all in the Air Force, and the people around them understand these basic common sense, and Hong Shengli understands it even better, so Lin Guanghua, who is not far away, saw that he was still manipulating with a calm demeanor, and seemed to be very confident, so he picked up the radio and asked the tower: "How is the situation?"

"The altitude is nine thousand two, the speed is 182 kilometers per hour, and it is currently maneuvering and circling one kilometer due north. ”

Hong Shengli's radio station was turned on very loudly, and this kind of communication with the tower was as clear as possible, so the sound spread very openly, and everyone around could hear it, so the people around them opened their eyes in surprise, and something called disbelief appeared in each other's eyes.

Altitude and speed have been automatically ignored by these people, because all that surprised them was the last four words of the tower.

What does this mean? The power of people's drones is not affected at all at high altitude, and they can not only fly normally at high altitude, but also do hovering movements.

You must know that it is good for their fighters to fly level at this altitude, even if they risk going up, they are basically going straight up and down, circling, or saving it, in case the evil high-altitude current blows a few times, the hovering is not done well, and it is not good to drop two parts.

"Which of you has seen the time, and how long has the drone been on it?"

Suddenly, someone realized a question and began to ask the person next to him, so the people around him looked at their watches, some said three minutes, some said five minutes, and some said eight minutes.

There were so many things, but soon the voices of the people came to an abrupt halt, as if they had been agreed.

Whether it is three minutes or eight minutes, it is more than the two minutes discussed before, and this is not only powerful in terms of power, but also very good in terms of overall structure, and at least in terms of quality, it is much stronger than the aircraft equipped by the troops.

So the noisy discussion sounded in a low voice:

"This can't be imported, right?"

"How is that possible?"

"How is it impossible! Have you ever heard that there are such planes in China? Besides, haven't you heard that Luan Heping's family is an old Red Army and the main leader of the logistics department of a certain military region?

"It's really possible, I'll just say, how did the head of our army dig Luan Heping here, it turns out that there are such benefits. ”

There are a lot of similar words, and if nothing reaches Hong Shengli's ears, think about it, there is really this possibility, others don't know what Luan Heping's situation is, but the deputy commander of his army is still very clear, and his father is indeed a senior leader in the army.

So his tense face finally had a relaxed smile, and he beckoned to Luan Heping, and when he walked up, he asked, "You got this drone...... It's not a hassle, is it?"

"No trouble, no trouble~~" Luan Heping's big face smiled very honestly: "It was built by the Tengfei Factory in Huancheng, our troops want it, just give them a production task." ”

Luan Heping was still reserved in the previous words, but when he heard the back, Hong Shengli immediately opened his eyes wide, and looked Luan Heping up and down: "What do you say? This drone is not imported, it is made by Tengfei Factory itself?"

I don't know if it's too shocking, or too incredible, Hong Shengli's words are very loud, and the guys who are talking about imported goods are better than domestic goods When they heard this, their expressions immediately became more exciting and exciting.

An airplane that can maneuver and hover at a high altitude, without fear of power attenuation, and still soar, is actually domestically produced?

Hong Shengli also thinks it is impossible, domestic aircraft factories can't even guarantee the quality of fighter planes equipped by the troops, how can they make such a good high-altitude drone?

So I wanted to ask Luan Heping about the specific situation.

As a result, before he could speak, a report from the tower came from the radio: "There are cumulonimbus clouds over the airport, there may be thunderstorms, it is recommended to return!"

Hong Shengli was immediately frightened when he heard this, cumulonimbus clouds, and the possibility of thunderstorms, this is a complicated weather, their troops encountered this situation, without exception chose to return, otherwise they encountered extreme weather, and it was very likely to cause a first-class accident in which the plane was destroyed and people died.

Because of this, without waiting for others to report, he shouted anxiously at Lin Guanghua, who was controlling the drone, "The comrade who operated the plane, there are cumulonimbus clouds over the airport, and there may be thunderstorms, hurry up and return ~~~"

When the people around heard it, what was it? Cumulonimbus clouds, thunderstorms, oh my God, it was actually complicated weather, and all of them had worried looks on their faces.

Perhaps to make this worry more intense, Hong Shengli just finished shouting, the sky above the airport suddenly lit up, and then with the rumbling thunder, the airport was covered with rain, so the originally worried people immediately became anxious.

No one thought that the weather would change so quickly, the plane encountered this kind of weather, not to mention the bad luck, the danger factor will also increase exponentially, things in the sky are never a joke, even if 0.1% of the risk factor increases, it may cause irreparable losses.

Hong Shengli was even more anxious, he didn't care about his wet body, ran all the way to the jeep that Lin Guanghua was riding, opened the door and said to Lin Guanghua, who was hiding in the rain: "Hurry back, it would be a pity if the plane was lost." ”

Lin Guanghua gratefully glanced at Hong Shengli, who was thinking about the safety of the plane, and shook his head without hesitation: "If our plane falls down like this, it will be our failure." ”

Hong Shengli didn't expect his kindness, but in exchange for such a arrogant sentence, he was so angry that he wanted to turn his head and leave, but he didn't think that Luan Heping's voice came excitedly at this moment: "Chief, the tower said that there is no accident with the drone, everything is normal~~~"
