Chapter 943: Stall spin (2)

"Ghost, pay attention, airspace No. 13, with a height of 9,000." Captain Feng of the flight test group shouted over the radio in the tower.
This made Niu people feel uncomfortable for a while. In their eyes, that was an unlucky number.
It is not only that the elevator does not have 13 floors, but the number 13 must be skipped for various numbers.
Not to mention anything else, just talk about the Apollo moon landing rocket, nothing else is fine, just Apollo 13, not only did not finish the mission, but almost never came back.
Now, they actually choose to conduct a spin experiment in airspace 13. Is this appropriate?
However, they can only visit here, they can't speak, they don't have this right, and Han is an atheistic country and doesn't believe in God.
"The ghost is received." Chen Rui said. He already knows the airspace around the flight test institute. The airspace below No. 13 is very empty and a vast field. When winter is here, work stops in the countryside. Outside There is no one, so even if the plane falls, it will not cause any harm to the ground.
Moreover, there is still a dry riverbed there, and when it is critical, you can make an emergency landing in the riverbed.
The fighter rumbled and flew into the airspace No. 13, Chen Rui glanced at the dashboard: "The ghost has arrived in the airspace No. 13, at an altitude of 9,000, and a speed of 800. It is requested to be tested."
At this moment, the tower of the Flight Test Institute was silent, only Captain Feng's voice: "The flight test begins!"
Start!
Chen Rui pulled the joystick back, and the fighter began to raise the angle of attack.
Since it is a fly-by-wire aircraft, there are already restrictions in the operating system. Under normal circumstances, it is impossible to enter the spin. Chen Rui can enter the big welcome only after canceling the angle of attack limiter in the aircraft system. angle.
The plane began to climb upward, and the elevation angle of the plane was getting higher and higher. Then, when the angle of attack had reached sixty degrees, Chen Rui pushed the control stick aside.
In an instant, both of them felt the blood surge, their eyeballs protruding, and at the same time, the fighter plane began to spin.
While rotating around a horizontal axis, it began to fall downward.
"The ghost has entered the tail spin."
"One."
At the same time, Kelly in the rear cabin had already begun to shout. She still remembered her mission. After entering the spiral, she had to count to see how many turns she had rotated.
"two."
Kaili didn't feel scared at this time. I don't know why. She was full of trust in the pilot in the front cabin. There is nothing that Chen Rui can't do. As long as he is there, everything is nothing!
"three."
Kaili remembered that she was trapped in the cockpit and there was a fire behind her at the Niu China Air Show. At that time, Chen Rui ran up to the rescue so bravely. At that time, she already had a strange feeling in her heart.
"Four." Yesterday, when Kelly saw the girl, she also saw the strange look in the other person's eyes, but Kelly didn't care. Of course she knew that as a pilot, she was subject to too many restrictions. It was not just love. To be able to be together, but not forever, but only for once possessed, as long as we have been in love together, that is enough.
Like now.
"Five." After Kaili shouted the number, she found that Chen Rui was still motionless, and she was shocked. God, could it be that he turned faint?
"Hey, that's enough." Kelly called.
"The altitude is still there. Make another two turns." Chen Rui said calmly in the front cabin.
At this time, the height is three thousand.
Two more turns? That height is only about a thousand left, he is a lunatic, don't you know how important height is to recovering the spin?
He only has one chance. Once he can't recover, he won't even have the chance to skydive!
After all, there is no zero ejection seat yet.
"six."
Kaili was surprised in her heart while continuing to count. When the count reached seven, Chen Rui finally moved.
At this moment, the plane entered the spiral to the left. Chen Rui pushed the throttle stick to the idle state with his left hand. At the same time, he pushed the control stick to the farthest to the right with his right hand, and the rudder was stopped with his right foot. A strong rudder surface moment came from the tail.
The lower the height, the less time left for reaction. At the same time, the lower the height, the denser the air and the higher the efficiency of the rudder surface! Chen Rui is a brave master of art, the telex operating system, only a slight force is sent back, and at the same time, the feeling of dizziness is getting smaller and smaller.
"Eight hundred in height." Kelly shouted.
"Six hundred in height."
Once the height is less than five hundred, it will lose the chance of survival because the height is not enough and the parachute cannot be opened.
At this moment, the fighter plane completely got rid of the spiral and flew forward horizontally. Chen Rui fully opened the throttle to reach the maximum military thrust, and the fighter plane began to accelerate.
"The ghost report has successfully recovered the spin." Chen Rui shouted over the radio.
In an instant, there was joy in the tower behind.
The number of laps is not counted in this way. If you have enough laps, you can change it out. Instead, you can change it out immediately after you enter the spiral. It only takes a few laps to change it out.
However, Chen Rui was confident and uncertain about subjects. He would not do it. Now, the tower is full of joy, and the people of the cattle country present are extremely admired.
"Your military aircraft research and development has indeed reached the level of a first-class aviation power, but unfortunately, your engine is still weak." Stanley said to Qin Guan: "Relying on the Spey engine, even Spey's modified version. The engine cannot support the sky in the future."
Stanley is right. Spey has improved to 11.5 tons of thrust, which has reached the limit of its potential, and the world’s third-generation high-thrust engine will start with a thrust of more than 12 tons, and its thrust-to-weight ratio must exceed 8. So, the fuel consumption rate needs to be further reduced.
"Yes, of course we know this. We will make every effort to complete the research and development of the new third-generation engine. I believe our scientific researchers." Qin Guan said.
Of course Qin Guan knows what the other party's idea is. Han can jointly develop it with their Luoluo company. It is said that it is a joint development. As a result, Han has only paid for it, and can't learn technology or anything. Such a lesson, More than once in history.
Niu country can be sold to its own Spey, that is the technology of 20 years ago, it will definitely not be sold to its own latest engine technology.
Lian Spey has made so many stumbling blocks in the middle, so do you have to think about other things?
Niu country is absolutely impossible to find, if you have to find it, it is almost the same to find Hans country.
Hans State has the weakest aero engine. This is due to the restrictions imposed on them after World War II. If necessary, look for Hans State. Everyone has common pursuits and can come together.
Such an idea suddenly came to Qin Guan's mind.
In the distance, the roar of the engine came, and the JH VII completed the test flight project and has returned to the field.
