Zhuang Yan was still unable to arrive in time.

Although he ran fast enough, it took only a few minutes for the aircraft to fall, and no matter how fast his legs were, the speed of the fall could not be faster.

He watched as Zhang Neng's powered delta wing fell to the ground in a strange spiral roll like a wounded bird in the sky.

Later, from Xu Yan's mouth, Zhuang Yan knew that this was the stall that the powered delta wing was most afraid of encountering during extreme flight.

This kind of accident usually occurs when the power delta wing is under the extreme attached load when performing a large angle maneuver.

Because the entire power delta wing is in the limit state, as long as it encounters a little unexpected airflow, it can make the whole already in a very fragile posture instantly unbalanced.

The consequence is a stall.

Stalling means losing control of the aircraft, which is extremely scary.

Whether it can change the attitude in the end and recover the aircraft from this **** lethal 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 to have a conversation with Zhang Neng in the air.

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

"The height is still there, and it can be corrected. If the recovery is successful, it can leave more precious data for subsequent research and development and use..."

There was a hint of anxiety in Zhang Neng's tone, but he was generally calm.

"Director Zhang! Abandon the plane!"

Xu Yan felt that Zhang Neng was really crazy.

Now, what data do you need?

Zhang Neng has a nickname in the Airborne Corps Research Institute, and his colleagues actually call him "madman" behind his back.

Where is crazy?

He does projects that others are not optimistic about, and he does it for several years.

Like this powered delta wing project.

Some "smart people" said that this thing is not a big power weapon like a fighter jet, and the price is not expensive, why invest money in research and development? It is better to order directly from foreign manufacturers. It saves money and trouble, and there is no need to make trouble with yourself.

As plausible as it may sound, "bringing doctrine" has always been convenient.

But Zhang Neng argued that it was short-sighted! This is shortsighted! If you can buy equipment, you can't buy technology; if you can buy power delta wings, you can't buy independent research and development and production!

If it is always "bringing", if a war breaks out one day and others block it, you will be in a mess!

Seeing a blushing neck and a berserk look, those "smart" people laughed when they saw it, and said I would just say it, why do you talk like a murderer?

Zhang Neng's temper came up, saying that you are harassing our army!

The "smart" person said, "It's not that serious, isn't it just a small powered delta wing? You can say it as seriously as Zhang? Don't be on the line, you're alarming!"

At the end of the dispute, Zhang Neng clapped the table. In the end, it was the leadership and coordination. He said that he would try it first and see if there were any results. For a two-year period, if he couldn’t come up with a better power delta wing than foreign countries, the project would be dismantled.

Zhang Neng clapped his chest and made a promise: "Okay, two years, I can't figure it out, I, Zhang Neng, plead guilty, and am willing to suffer any military discipline punishment!"

Everyone in the room laughed and said that Lao Zhang was not that serious, it was just a project, how could he make it look like he was on the battlefield?

Zhang Neng said: "In times of peace, this is the battlefield! It's not about charging forward with guns to kill the enemy. We are also engaged in military research. We don't have good equipment. If there is a war in the future, it will be filled with the lives of children and soldiers. I would like to ask everyone here, whose daughter will go to the battlefield in the future, and who doesn't want their sons and daughters to have advanced equipment?!"

Everyone was silent.

No one will argue with Zhang Neng anymore.

This is not a man to argue with.

The wall stands thousands of miles, and there is no desire to be rigid.

If people do things wholeheartedly and unselfishly, no one has to obey, at least not on the surface.

This is how the project started. Zhang Neng brought a female disciple Xu Yan and an old volunteer soldier Chang Jiageng who was about to change jobs. The three of them were thriving and rolled up their sleeves.

two years.

Now, a year has passed, and the original military order is still ten months away from expiring.

There is no joke in the army.

Even if no one wants to accuse Zhang Nengxing in the end, but with his character, he will definitely take the blame and resign.

A name that wastes scientific research funds is enough.

From design to factory trial production, to various field tests, and then to test flight.

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

Originally, about the test flight, according to Xu Yan, you can find amazing veterans or officers in the airborne special forces to come and do it.

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

Zhang Neng said with a smile: "Why do you call people? I am an expert in parachute and parafoil. I fly by myself, so I can't fly better than others? At least for me as a designer, I can better experience the shortcomings of the aircraft. Tell me about it from someone else's experience, it's like looking at a beauty through a layer of veil, it always feels a little hazy, and it's meaningless."

Xu Yan knew that no one could change what Zhang Neng could decide by persuading her master.

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

Zhang Neng was reluctant to let others do it.

At this moment, Zhang Neng, who was at an altitude of more than 1,000 meters, tensed the nerves of his whole body.

Don't panic!

He admonished himself.

The more you panic, the easier it is to make mistakes!

Chance!

He's waiting for a chance to get out of this **** stall.

Now that the rear powertrain has been shut down, the first priority in a stalled state is to correct the attitude.

As long as the attitude of the powered delta wing is corrected and it is in a normal flight state, it can glide even without power.

The needle on the altimeter is constantly turning to the left...

1000…

900…

800…

Still can't get out of the stall.

The delta wing is like a bird that has been hit, it is falling weakly towards the ground.

In the earphones, the anxious voice of female disciple Xu Yan came over and over again, and it sounded a bit piercing.

"Please! Skydive! Master, don't be stubborn!"

"I can! I can!"

Zhang Neng kept repeating this sentence, and he didn't know whether to answer Xu Yan or to cheer himself up.

I can.

Three words, the simplest expression, contain infinite courage.

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

Since entering the military academy, these words have accompanied Zhang Neng through countless difficulties and obstacles in his life.

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

Grabbing the crossbar of the delta wing with both hands, Zhang Neng clenched it tightly and tried to lift it upwards - only in this way will it be easier to obtain the resistance of the airflow and change the whole posture.

The height is still falling~lightnovelpub.net~ In just over 20 seconds, the delta wing has fallen to only two hundred meters from the ground.

At this time, Zhang Neng was relieved.

Even skydiving, the last favorable opportunity has passed.

This is not a fighter jet, there are automatic ejection compartments, no automatic parachutes, everything can only be manual.

There is still a glimmer of hope for skydiving in the sky, and now it is gone...

The power delta wing is still in a right-spin stall, and the huge ground is like the wings of death, rushing towards Zhang Neng.
