In order to rush the work and also to adapt to the national conditions, just like the engine, some parts of the aircraft were also forced to be modified.

Although subsequent test flight inspections showed that there were no problems with these modifications.

But it is an excuse for the other party to develop.

"Stop talking, let's start!"

Just as the three of them were whispering to each other, the deputy director of the factory came over and said. After hearing this, the three of them hurriedly came to the side and stared at the sky.

"What speed?"

Mr. Zhang asked.

The speedometer on the side immediately replied, "Chief, it should be around Mach 1!"

Mr. Zhang nodded and picked up the telescope again.

"Tower, I'm ready to request the inspection to begin!"

The test pilot's voice came from the loudspeaker on the side, followed by the tower's voice, "Tower received it, approved for inspection!"

"Repeat, agree to the test!"

The words fell, and then in everyone's field of vision, the test flight YJ08 aircraft accelerated violently.

I saw that the originally slow-looking plane suddenly accelerated its speed, as if the original tortoise had turned into a hare in my field of vision.

"Mach 1.5!"

"Mach 2.0!"

The speedometer immediately started reporting the numbers, and everyone's hearts were in trepidation.

"Mach 2.4!"

"Mach 2.6!"

bang bang bang bang

Applause suddenly sounded, and a smile appeared on Mr. Zhang's face.

But this only meets the design requirements, no, it should exceed the design requirements.

call…

Mr. Zhang let out a long breath and finally had an explanation!

The people at the aircraft factory behind him also breathed a sigh of relief.

"Chief, it's over!"

Yuan Mei came up and said softly.

"Tower, tower... tower"

Tsk la la la

laugh…

"The plane is not stable..."

The test pilot's voice suddenly came from the loudspeaker, but the communication was intermittent, so the people at the observation platform were quiet.

"Lao Yuan, what's wrong?"

The factory director stepped forward quickly, looking anxious!

Yuan Mei also looked confused and didn't understand what was going on with the plane.

"No, the plane is out of control!"

Suddenly, someone shouted loudly, and then they saw the plane in the sky heading diagonally towards the ground.

"Quick, let, let the pilot jump down!"

In the blink of an eye, the plane had fallen several thousand meters.

Mr. Zhang looked heavy, but he still made the quickest decision.

"The plane, I can't lift my head..."

The test pilot's voice came from the loudspeaker, and then the next second the test pilot's high voice was heard.

"stand up…"

"Get up..."

"Wang Hang, jump out for me, jump out for me..."

Bang…

The test pilot finally ejected from the plane at the last moment.

boom!!!

The plane fell to the ground and sparks exploded!

"Quick, hurry up and save people!"

snap

Yuan Mei's face turned pale and she sat down on the ground.

The factory director and secretary beside him also turned pale.

"Originally, it should be no problem!"

"How could this happen? How could this happen?"

Yuan Mei murmured, her eyes filled with despair.

Half an hour later.

Mr. Zhang came to the ambulance with a livid face. At this moment, the test pilot was lying in the car.

"Chief!"

When he saw a group of people coming, the test pilot burst into tears.

"It's me. It's me who didn't fly well. It's me who thinks I can still fly faster!"

"But, I didn't expect that the plane's head would feel like a stone was weighing on it, and I couldn't lift it up at all!"

"Chief, it's my fault, it's all my fault!"

"All the hard work of my comrades has been ruined by me. I, I..."

The test pilot was crying, looking sad.

Mr. Zhang reached out and patted the test pilot on the shoulder, then comforted him, "Don't think about anything, just take good care of yourself!"

After saying that, he waved and was sent to the hospital.

Looking back, everyone from the aircraft factory was there.

Yuan Mei's face tightened, and she suddenly said, "Chief, I should know what's going on."

As soon as he finished speaking, everyone looked over immediately.

"explain!"

"I heard from comrade test pilots that when the aircraft is going fast, the head feels like a stone is pressing down on it. That's because the wind pressure at high speeds was not fully considered during the design..."

"That is to say, after exceeding a certain speed, the pressure on the aircraft is very large. If the design is unreasonable, it may, may become unbalanced..."

"alright!"

Mr. Zhang stretched out his hand to interrupt, "Go back and write a record. It needs to be detailed!"

"yes!"

Yuan Mei's heart trembled.

Although the reason was found, this was also a flaw in their design.

"Chief!"

The secretary and factory director walked up to Mr. Zhang, followed by everyone from the aircraft factory.

All of them looked ugly and felt uneasy.

But in front of Mr. Zhang, they were not happy at all!

"Chief, we have tried our best!"

It took a long time before the factory director said a word.

Tears have been shed!

Mr. Zhang nodded silently in his heart.

They really tried their best!
Chapter completed!
