Chapter 208

It's no wonder that the officers and soldiers around them are like this. Nine kilometers is far higher than the 5000 meters they usually train.

That's all. At such a high altitude, the oxygen content in the air decreases sharply, which is a severe test for the power of the aircraft. Among other things, the J-6 and J-7 equipped by their troops, let alone the afterburner, are very careful in their normal cruising. They have no choice but to worry about the condition of the aircraft. If something happens, it will be difficult.

It is reasonable to say that the army's equipment should be very good. Even they dare not rush to this height. How can it not surprise people that an unknown aviation model should rush up.

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

You should know that the two cylinder gasoline engine is used on the UAV. The power output and fuel condition are far worse than jet power, and the UAV relies more on combustion supporting gases such as oxygen. Therefore, in general, the UAV with such power will not last long at high altitude.

That's why the model aircraft of the sports system can fly to a height of 5000 meters, which is already a record breaking reason. It's not that they don't want to fly high. It's that the power of the power plant drops sharply at high altitude, which is not enough to support the aircraft to continue to go up.

They all worked in the air force. The people around them knew the basic knowledge, and Hong Shengli knew it better. So Lin Guanghua, who was not far away, saw that he was still operating with a self-confident manner, and seemed to be very confident. He picked up the radio and asked the tower, "what's the situation?"

"At an altitude of 920 and a speed of 182 km / h, we are now circling one kilometer due north."

Hong Shengli's radio station is very large. The clearer the communication with the tower, the better. So the voice is very open and can be heard around. Everyone around opens their eyes in surprise. Something called incredible appears in each other's eyes.

Altitude and speed have been automatically ignored by these people, because what surprised them was the last four words of the tower - maneuver hover.

What does that mean? The power of the UAV will not be affected at high altitude. It can not only fly normally at high altitude, but also do hovering action.

It's good to know that their fighters can fly flat at this altitude. Even if they take risks, they basically go straight up and down and circle. It's better to save. In case the evil high-altitude airflow blows a few times and the circle is not done well, it's not good to lose two parts.

"Which of you saw the time? How long has the drone been on board? "

Suddenly someone realized a question and began to ask the people nearby. So people around them looked at their watches one after another, saying three minutes, five minutes and eight minutes.

All kinds of things, but soon people's voice will be the same as the appointment, suddenly stopped.

Whether it's three minutes or eight minutes, it's more than the two minutes previously discussed. It's not only powerful in power, but also excellent in overall structure. At least, it's much better than the military aircraft in quality.

So the noise of discussion is low and low:

"this thing is not imported, is it?"

"How could it be?"

"No way! Have you ever heard of such a plane in China? Besides, did you not hear that Luan Heping's Lao Tzu was an old Red Army and the main leader of the Logistics Department of a military region? It's not a matter of a word to get some imported goods? "

"It's really possible. I'll tell you how our army chief dug Luan Heping here. It turns out that there are still such advantages."

There are many similar words, if not, spread to Hong Shengli's ears. If you think about it, it's really possible. Others don't know what happened to Luan Heping. His deputy commander of the army is very clear. His father is indeed a senior leader in the army.

So the tense face finally had a light smile, waved to Luan Heping, and when he came to him, he asked: "you made this UAV No trouble? "

"No trouble, no trouble ~ ~" Luan Heping's big face was very simple and honest: "the take-off factory in Huancheng city is built. Our troops want to approve a production task for them."

Luan Heping also nodded in reserve in front of the words, but after hearing it, Hong Shengli immediately opened his eyes and looked at Luan Heping up and down: "what do you say? This drone is not imported? Is it made by Tengfei factory? "

I don't know whether it's too shocking or too incredible. Hong Shengli's voice is very loud, and the people around him are talking about that the imported goods are better than the domestic goods. When they hear this, their expressions are as wonderful as they can be.

Is the aircraft that can maneuver and hover at high altitude, fearless of power attenuation, and still hover home made? How is that possible?

Hong Shengli also thinks that it's impossible. Domestic aircraft manufacturers can't even guarantee the quality of fighters equipped by the army. How can they produce such a good high-altitude UAV?

So I want to ask Luan Heping the specific situation.

As a result, the radio station has not yet opened its mouth, but a notice from the tower came: "cumulonimbus clouds appear over the airport, thunderstorms may exist, it is recommended to return home!"As soon as Hong Shengli heard this, he was immediately frightened. The possibility of cumulonimbus and thunderstorm was complex weather. In this case, all his troops chose to return home. Otherwise, they would encounter extreme weather, which would most likely lead to the first-class accident of aircraft damage and human death.

Because of this, without waiting for others to report, he yelled anxiously at Lin Guanghua, who was operating the UAV over there: "that comrade, there are cumulonimbus clouds over the airport, and there may be thunderstorms, so hurry to return home ~ ~"

when people around listen, what? Cumulonimbus, thunderstorm, my God, it's a complicated weather. There are worried faces.

Maybe it's to make this worry even more acute. Just after Hong Shengli's shout, the sky above the airport suddenly lights up. Immediately, with the roar of thunder, the airport is covered with rain, so the people who were worried about it immediately get anxious.

No one expected that the weather would change so fast. When a plane encounters this kind of weather, the risk factor would increase exponentially. Things in the sky are never joking. Even if the risk factor increases by 0.1%, it may cause irreparable losses.

Hong Shengli was even more anxious. Regardless of his wet body, he ran all the way to Lin Guanghua's jeep. He opened the door and said to Lin Guanghua, who was hiding in the rain: "return quickly. It's a pity if the plane is lost."

Lin Guanghua looked gratefully at Hong Shengli, who was thinking about the safety of the plane. Without hesitation, he shook his head: "if our plane falls like this, it's our failure."

Hong Shengli didn't expect his kindness, but he was so arrogant that he wanted to turn his head and go. At this moment, Luan Heping's voice excitedly said: "chief, the tower said that there was no accident with the UAV, everything was normal ~ ~"

"
