"OK!"

Jiang Jinlin was really not a joke. He took off the big block and handed it to Officer Ma, took the helmet handed over to Han Xiaobei and buckled it on his head.

Secretary Ma didn't expect that the leader was coming to the real world. When he saw that he was on the flying helmet, he became anxious.

"Teacher... are you really flying?"

Tang Wenkai also did not expect this situation to happen. He thought that the teacher would just say this to the boy Zhuang Yan.

Unexpectedly, Zhuangyan took it seriously and the teacher also took it seriously.

Fucking...

The commander of a dignified division is with the solemn triangular wings...

"Zhuangyan, are you crazy?" He glared at Zhuangyan.

Zhuang Yan said to Jiang Jinlin: "Teacher, I'm just kidding, don't take it seriously."

I didn't expect Jiang Jinlin to stop doing it.

"Zhuangyan, what did you say to me just now?" He said: "There is no joke in the army. Are you making fun of me?"

Zhuang Yan hurriedly said, "I dare not, if you get on, I will take you flying. I'll have no problem."

After saying that, he turned to Tang Wenkai: "Battery Commander, this is not my business. I have persuaded you. This is the commander of the division commander, and I am just executing the order."

Tang Wenkai and Secretary Ma still wanted to persuade him, but Jiang Jinlin blocked his hand: "What's going on with you? The division commander can't fly the triangular wings? It's not me who drives, why are you panic? Then again, if I come, I don't even dare to sit on the triangular wings I approved to buy..."

He looked back at the group of soldiers from the reconnaissance battalion who were already stupid not far away.

"Can I still let others sit on it? Our army, capable officers should take the lead. Those who are afraid of death are not good officers. Why do you ask me to come with me? That's it! Don't persuade me. Come on, that platoon leader..."

He looked at Han Xiaobei: "How do you lock this thing?"

While saying that, he pointed to the helmet on his head.

Han Xiaobei hurried up and helped Jiang Jinlin wear a helmet.

Zhuangyan went to check the fuel tank, and only flew twice in the morning, and most of the fuel was still there.

Check the anti-stall lever and joystick, push it to the trim position, then check the flight line, engine water temperature, return to the zero altimeter, and start the engine.

Jiang Jinlin has already done it and has buckled the seat belt.

Sharply turn the head of the machine, look ahead, confirm that there are no obstacles on the ground, then release the brakes and start to refuel slowly...

Jiang Jinlin sat in the back seat, with the propeller and engine behind him. He could feel a sense of wind blowing on his back, and couldn't help but look back.

Seeing this little move, Zhuangyan smiled and said, "Teacher, don't worry, as long as you don't reach into the engine, it's okay."

Jiang Jinlin said: "Stop talking nonsense, fly!"

Smilingly responded: "Okay! Teacher, please sit down! I'll take you to the sky and stroll!"

...

Looking at the power triangular wing that was rising from the ground, Director Ma shook his head and said, "Our teacher... is really brave..."

Tang Wenkai said: "You are afraid you won't know that the division commander used to be a paratrooper."

...

Looking at the speedometer of the triangular wing, it had reached 50 km/h. He gently pushed the rod forward and the heaven and earth line began to fall downward.

Suddenly, the cockpit head raised, the front wheels off the ground, and began to lift upwards.

The solemn return rod to the trim position, and the two main wheels behind it were lifted and followed it off the ground.

The triangular wings jumped up lightly like a bird and flew into the sky.

The scenery on land is getting smaller and smaller. When the power triangular wing rises, the inclination angle is slowly adjusted solemnly.

This is very critical.

Each wing has an angle of attack limit.

Angle of attack is the angle between the direction of the advance and the chord line, also known as the angle of attack, which is the reference for determining the posture of the wing in the airflow.

This angle is also divided into positive and negative angles - when the airflow points below the wing, it is a positive angle of attack; when the airflow points above the wing, it is a negative angle of attack.

When the positive angle of attack increases, the lift increases and the rising speed is fast. However, there is also a limit, which is called critical angle of attack. Each delta wing has different critical angles according to the design. The consequence of being too big is that the lift will suddenly drop sharply, and the delta wing will fall down due to the loss of lift, causing "stall".

The same is true for negative angle of attack, as being too large will also cause stalls.

There is also the flight speed. Each delta wing has a minimum speed. Below this speed, there is also a risk of stalling.

The minimum speed of this triangular wing is 50 km/h. Below this speed, it will cause stall.

The current positive angle of attack is a bit large.

After the height reached 20 meters, solemnly relaxed the control rod, pushed it back to the trim position, and then corrected the left tilt.

The powered delta wing began to glide steadily in the air.

Since Jiang Jinlin looked at the sea below, the waves were sparkling, and there was a white light shining under the sun.

There are many small islands in the waters nearby. The triangular wings fly to the nearest island and begin to circle around the island.

"Teacher, have you seen the island below?"

Jiang Jinlin nodded: "See it!"

Zhuangyan said: "Even if this island is airborne, it is very difficult, because it is full of rugged hillsides and stones, and the beach is long and narrow. Even if it is airborne, it may encounter sea breezes and blow into the sea. However, the triangular wings are fine. As long as there is a gliding distance of 50-70 meters, you can land and take off."

Jiang Jinlin nodded constantly, and the island was at his feet, and now he could see it.

This can also be reconnaissance, and if it is night, you can also land secretly.

"Actually, the ceiling of our power delta wing is still very low. When I was at Red Arrow, I tried a power delta wing developed by our army. It can fly more than 5,000 meters. Unfortunately, it failed during the limit test and the research institute was seriously injured. It has not been distributed to our domestic delta wing for so many years. I am afraid that the project will be suspended. If we are domestically produced, the price will not be as expensive as it is now."

He couldn't help but think of Zhang Neng.

The master who was once, was also the enlightenment master who was on the power triangle wing.

The Zhuangyan's power triangular wing also flew quite well in the special forces. After Zhang Neng had an accident, Zhuangyan never saw Researcher Zhang again.

When the Red Arrow Team sent him to a local flight club in Beijing to study the power triangular wing, Zhuang Yan once met some special forces colleagues. When talking about Zhang Neng, a colleague of the airborne troops said that Researcher Zhang was seriously injured and that the domestic project was delayed.

Zhuang Yan felt it was a pity that he felt that the triangular wing that Zhang Neng tried to produce back then was much better than the one he drove now.

After so many years, I don’t know what happened to Zhang Neng or the project.

He hopes that one day he will suddenly hear the news of the localization of the power delta wing.

Unfortunately, there has been no news.

Jiang Jinlin suddenly asked: "Shengyan, what is the most afraid of the triangular wings in the air?"

"Stop." said solemnly: "Or the engine stops, but parking is generally easy to restart, and the engine is very reliable."

Jiang Jinlin asked again: "You said that even if the engine stops, it can glide?"

Zhuangyan said: "Teacher, do you want to try gliding?"

Jiang Jinlin laughed: "Why don't you dare? I have been a paratrooper myself. I dare to jump at a height of thousands of meters. What am I afraid of?"

"Okay, let's slide him for a while."

Then I thought about the ground report in my headset: "Ground finger, I plan to turn off the power in the air and glide, please pay attention."

"What!?" Han Xiaobei laughed, and his scream came from his headphones: "Old squad leader, are you carrying the division commander!"
