Zhuangyan still failed to arrive in time.

Although he ran fast enough, it was enough for the aircraft to fall for only a few minutes. No matter how fast his legs were, they could not fall at the speed.

He watched Zhang Neng's power triangular wings crashing down to the ground in a strange spiral rolling manner like a wounded bird in the sky.

Later, from Xu Yan's mouth, Zhuang Yan realized that this was the most feared thing about the entire aircraft rollover and stall caused by the powered delta wing during extreme flight.

This kind of accident usually occurs when the powered delta wing is at the extreme load with large angle maneuver.

Because the entire power delta wing is in the extreme state, as long as you encounter a little unexpected airflow, the entire posture that is already in a very fragile can be instantly unbalanced.

The consequence is stalling.

Stall means losing control of the aircraft, which is extremely terrible.

In the end, whether you can change your posture and change the aircraft into this damn fatal state depends entirely on the pilot's experience and calmness.

Xu Yan arrived earlier than Zhuang Yan, and held a walkie-talkie near the crash site and had a conversation with Zhang Neng in the air.

"Director Zhang, abandon the machine! Abandon the machine!"

"There is still a height, and it can be changed. If the change is successful, it can leave more precious data for subsequent research and development and use..."

Zhang Neng's tone was filled with anxiety, but overall it was calm.

"Director Zhang! Abandon the plane!"

Xu Yan felt that Zhang Neng was really crazy.

At this time, what other data is needed?

Zhang Neng has a nickname in the Airborne Institute, and his colleagues call him "crazy" behind his back.

Where is crazy?

Others don’t like projects, they do them, and they will take several years to do them.

Just like this project of the dynamic delta wing.

Some "smart people" say that this thing is not a heavy weapon of a major country like fighter jets, and the price is not expensive, so why invest money in research and development? It is recommended that you just need to order it with a foreign manufacturer, which saves money and trouble, and there is no need to be unable to get along with yourself.

It sounds very reasonable, and "taking it out" is always convenient.

But Zhang Neng argued with reason and said that this was short-sighted! This was short-sighted! If you can buy equipment, you can't buy technology; if you can buy power delta wings, you can't buy it from the main research and development and production!

If it is always "using the ideology", if one day war breaks out and others block it, they will be in trouble!

Seeing the blushing face and his neck looked like he was running wild, those "smart" people laughed and said, "I'll say, why do you have to speak like an enemy who killed your father?"

Zhang Neng's temper came up and said that you are cheating on our army!

"Smart" said: "It's not that serious, isn't it just a small dynamic triangle wing? It's as serious as you Zhang Neng? Don't exaggerate it, you're exaggerating!"

At the end of the dispute, Zhang Neng slapped the table, and finally the leader coordinated and said to try it first to see if there were any results. It took two years to make a better dynamic delta wing than foreign countries, so the project was discontinued.

Zhang Neng patted his chest and promised: "Okay, I can't do it for two years. I, Zhang Neng, apologized for my crime and was willing to be punished by any military discipline!"

Everyone here laughed and said that Lao Zhang was not that serious, it was just a project, so why did it look like he was on the battlefield?

Zhang Neng said: "In peacetime, this is the battlefield! It is not just a charge forward with a gun to kill the enemy. We are also engaged in military scientific research. If there is no good equipment, if there is a war in the future, it will be filled with the lives of the soldiers! Who is here? Whose daughter is in the army and will not want their children to have advanced equipment?!"

Everyone was silent.

No one argued with Zhang Neng anymore.

This is not someone to argue about.

A wall stands thousands of feet high, and a strong person will be without desire.

If a person does things wholeheartedly and selflessly, no one will be reluctant to accept it, at least on the surface, he dare not disobey.

The project began like this. Zhang Neng took a female disciple Xu Yan and an old volunteer soldier Chang Jiawen who was about to be transferred. The three of them were prosperous and rolled up their sleeves and did it.

Two years.

So far, a year has passed, and the original military order has expired in ten months.

There is no joke in the army.

Even if no one wants to sue Zhang Nengxing in the end, with his personality, he will definitely resign.

A name that wastes scientific research funds is enough.

From design to manufacturer trial production, to various site testing, to test flights.

In order to get the most intuitive first-hand data, Zhang Neng even tested the flight himself.

Originally, according to Xu Yan, you could find amazing veterans or officers in the special forces of the airborne troops to do this.

Anyway, the airborne troops have been trained to fly various wing parachutes and power parachutes since the mid-to-late 1990s, but they have not been equipped on a large scale and are popularized. They are all in the experimental stage.

Zhang Neng smiled and said, "What do you want to call someone? I am an expert in parachute and parachute. I am not better than others when I fly by myself? At least for me, a designer, I can experience the shortcomings of the aircraft. I always experience it better than others. I will tell you it. It's like watching a beauty through a layer of yarn. I always have a little hazy feeling and the meaning of shortcomings."

Xu Yan knew that no one could change what Zhang Neng decided to do.

After all, she also knew that the above reasons were just one of Zhang Neng’s test flights himself, and the more important reason was that the test flight itself was an extremely dangerous task.

Zhang Neng was unwilling to let others do it.

At this moment, Zhang Neng, who was above altitude of more than a thousand meters, tensed up his nerves all over his body.

Don't panic!

He warned himself.

When dealing with special situations in the air, the more you panic you will be, the more likely you will make mistakes!

Chance!

He was waiting for a chance to change into this damn stall state.

Now the power system behind has been turned off. In a stalled state, the first priority is to correct the posture.

As long as the posture of the powered delta wing is corrected and in a normal flight state, you can glide even if you don’t have power.

The pointer on the altimeter is constantly turning toward the left...

1000…

900…

800…

Still unable to change the stall state.

The triangular wings were like a hit bird, falling weakly towards the ground.

In the headphones, the anxious voice of the female disciple Xu Yan came again and again, sounding a heart-wrenching smell.

"Please! Skydiving! Master, stop being stubborn!"

"I can! I can!"

Zhang Neng kept muttering this sentence, not knowing whether to answer Xu Yan or cheering him up.

I can.

The simplest expression of the three words contains infinite courage.

Dare to face death directly, this is the life of a man!

Since entering the military academy, this sentence has been with Zhang Neng through countless difficulties and obstacles in his life.

He believed that this time it would be the same as before.

He grabbed the crossbar of the triangle wing with both hands, and the sling could hold it tightly and lift it upwards. In this way, it would be easier to obtain the resistance of the airflow and change the entire posture.

The height is still decreasing.

In just over twenty seconds, the triangular wing had fallen to a place only two hundred meters away from the ground.

At this time, Zhang Neng felt relieved.

Even if you skydiving, the last favorable opportunity has passed.

This is not a fighter, it has an automatic ejection compartment, no automatic parachute, everything can only be manual.

There is still a glimmer of hope to jump at high altitude, and now there is no more...

The power triangular wing is still in the right rotation stall, and the huge ground is like the spreading wings of the god of death, rushing towards Zhang Neng.
