"Okay!"

Jiang Jinlin was really not joking, took off the big cap and handed it to Officer Ma, took the helmet handed over by Han Xiaobei and buckled it on his head.

Officer Ma didn't expect the chief to come for real, and when he saw that he had put on his flying helmet, he was also anxious.

"Commander...... Are you really flying? ”

Tang Wenkai didn't expect this to happen, and thought that the teacher would just say this to this kid Zhuangyan.

I didn't expect it to be solemn and serious, and the division commander was also serious.

Fuck it......

The head of a dignified division, with the solemn delta wing......

"Majestic, are you crazy?" He glared solemnly.

solemnly said to Jiang Jinlin: "Teacher, I'll just make a joke, don't take it seriously." ”

I didn't think Jiang Jinlin would quit.

"Solemn, what did you just tell me?" He said: "There is no joke in the army, what if you are doing it?" ”

Zhuang solemnly hurriedly said: "Don't dare, if you get on me, I'll take you to fly, I'll have no problem." ”

After speaking, he turned to Tang Wenkai: "Battalion commander, this is not my business, I can persuade it, this is the division commander's order I am just carrying out the order." ”

Tang Wenkai and Officer Ma still wanted to persuade, but Jiang Jinlin blocked it with his hand: "What's going on with you?" The division commander can't fly a delta wing? It's not me driving, why are you panicking? Then again, I wouldn't even dare to sit on the delta wing that I approved for purchase......"

He glanced back at the officers and men of the reconnaissance battalion who had already looked stupid not far away.

"Can I still get someone else to sit on it? Our troops, officers who have the ability should take the lead, those who are afraid of death are not good officers, how can you call me on? That's it! Don't persuade me. Come, that platoon commander......"

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

As he spoke, he pointed to the helmet on his head.

Han Xiaobei hurriedly went up and helped Jiang Jinlin put on his helmet.

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

The anti-stall lever and lever were checked, pushed to the trim position, then the flight tension line, the engine water temperature was checked, the altimeter was zeroed, and the engine was started.

Jiang Jinlin has done a good job and buckled up his seat belt.

Solemnly turn the nose of the plane, look ahead, confirm that there are no obstructions on the ground, then release the brakes and start slowly refueling......

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

Seeing this small action, he said with a smile: "Commander, don't worry, as long as you don't reach into the engine, you'll be fine." ”

Jiang Jinlin said: "Less nonsense, fly!" ”

Solemn smiled and responded: "Good! Teacher, sit down! I'll take you to the sky! ”

……

Looking at the power delta wing rising from the ground, Officer Ma shook his head and said, "Our division commander...... It's bold enough......"

Tang Wenkai said: "I'm afraid you won't know, the former division commander was a paratrooper. ”

……

Solemnly looking at the speedometer of the delta wing, it was already 50 km/h, he gently pushed the rod forward, and the line began to fall downward.

Suddenly, the nose of the cockpit cocked, the front wheels lifted off the ground, and began to lift upwards.

Solemnly return the rod to the trim position, and the two main wheels behind it are lifted, and they also follow off the ground.

Like a bird, the delta wings leap lightly into the sky.

The scenery on land is getting smaller and smaller, and as the power delta wing rises, the tilt angle is solemnly and slowly adjusted.

This is a critical time.

Each delta wing has an angle of attack limit.

The angle of attack is the angle between the forward direction and the chord, also known as the angle of attack, which is the benchmark for determining the attitude of the wing in the airflow.

This angle is divided into positive and negative angles – when the airflow is directed underneath the wing, it is a positive angle of attack; When the airflow is directed above the wing, it is a negative angle of attack.

When the positive angle of attack increases, the lift increases, and the ascent speed is fast, but there is also a limit, which is called the critical angle of attack. Each delta wing has different critical frontal angles according to different designs, and the consequence of too much is that the lift force will suddenly drop sharply, and the delta wing will fall downward due to the loss of lift, resulting in a "stall".

The same is true for a negative angle of attack, which is too large and will also cause a stall.

Then there's the flight speed. Each delta wing has a minimum speed, below which there is also a danger of stalling.

The minimum speed of this delta wing is 50 km/h, below which it will cause a stall.

The current angle of attack is a bit on the high side.

When the height reached 20 meters, Marely slowly relaxed the joystick, pushed it back into trim, and corrected the left tilt.

The power delta wing began to glide steadily through the air.

Since Jiang Jinlin looked at the sea below, the waves were sparkling, shining white under the sun.

There are many small islands in the sea near here, so I solemnly flew my delta wings near the nearest island and began to circle around the island.

"Commander, do you see the island below?"

Jiang Jinlin nodded: "I saw it!" “

"This island, even if it is airborne, it is very difficult, because it is all craggy slopes and stones, and the beach is long and narrow, even if you are airborne there, you may encounter the sea breeze and blow into the sea, but the delta wing is fine, as long as there is a gliding distance of 50-70 meters, you can land and take off." ”

Jiang Jinlin couldn't stop nodding, the island was at his feet, and now he could see it at a glance.

This can also be used for reconnaissance, and if it is night, it can also be secretly landed.

"Actually, the ceiling of our power delta wing is still very low, when I was in Red Arrow, I tried a power delta wing that our army was developing, which can fly more than 5,000 meters. It's a pity that it failed during the extreme test, and the institute was seriously injured, and our domestic delta wing has not been distributed for so many years, and I am afraid that the project has also been suspended. If we localize, the price will not be as expensive as it is now. ”

He couldn't help but think of Zhang Neng.

The former master of himself is also his enlightenment master on the power delta wing.

The solemn power delta wing also flew quite well in the special forces, and after Zhang Neng's accident, Zhuang Zhuang never saw Researcher Zhang again.

That year, when the Red Arrow Brigade sent him to a local flying club in the capital to learn power delta wings, Zhuang Zheng once met some special forces colleagues, and when Zhang Neng was mentioned, a colleague of the Airborne Forces said that Researcher Zhang was seriously injured, and the localization project was delayed.

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

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

He looks forward to the day when he can suddenly hear the news of the localization of power delta wings.

It's a pity that there has been no news.

Jiang Jinlin suddenly asked: "Solemn, what is the delta wing most afraid of encountering in the air?" ”

"Stal." "Or the engine stops, but it's generally easy to restart when stopped, and the engine is very reliable." ”

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

solemnly said: "Commander, do you want to try gliding?" ”

Jiang Jinlin laughed: "Why don't you dare? I myself have been a paratrooper myself, and I dare to parachute at an altitude of several kilometers, what am I afraid of. ”

"Okay, let's slip him a bit."

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

"What!?" Han Xiaobei laughed, and his exclamation came from the earphones: "Old squad leader, you are carrying the division leader!" ”

"It was requested by the division commander, and I obeyed the order!"
