Inside the tower control room.

As they watched the plane take off into the sky, they suddenly felt excited.

But they knew that now was not the time to get excited.

The test flights have just begun.

The first thing to be tested is the aircraft's maximum ceiling and the time it takes to climb to that ceiling.

The higher the ceiling and the shorter the speed, the more powerful the aircraft engine.

Qi Tongwei said to Wan Liyun:

"007, begin the maximum ceiling test."

Then, Wanliyun's voice was heard.

"understand……"

Then he piloted the plane and began to soar upwards.

Watching the altitude value on the instrument continue to rise.

Wan Liyun gradually increased his thrust, while his body was also bearing a huge load.

The engineer in charge of data monitoring next to Qi Tongwei kept reporting the altitude values.

"3000...4000...5000."

Qi Tongwei reminded:

"We're about to pass through the cumulonimbus clouds."

"clear."

In the plane, Wanliyun watched the black clouds getting closer and closer.

Lightning flashed across the clouds from time to time.

Airplanes are most afraid of being struck by lightning.

But at the current speed, it only takes a few seconds to pass through the cumulonimbus clouds.

Wanliyun calmed down and concentrated on flying the plane.

The atmosphere in the tower was equally tense.

Everyone knows that it is most dangerous for an airplane to fly through a cumulonimbus cloud.

"Altitude 6000, approaching cumulonimbus clouds."

Everyone held their breath and prayed for a smooth passage.

Qi Tongwei also had sweat in his palms.

However, just as the Wanli clouds turned into cumulonimbus clouds.

The thickness of the clouds was beyond his imagination.

What you fear will come true. Suddenly, a flash of lightning exploded before your eyes.

The plane was struck by lightning.

Suddenly, a rapid alarm sounded in the cabin.

Immediately afterwards, the right engine lost power and the aircraft began to drop rapidly.

In the tower, technicians saw the aircraft's altitude continuously dropping.

He immediately shouted: "The plane's altitude is suddenly dropping rapidly, 5000, 4500..."

"broken……"

Hearing this, everyone knew something might have happened.

Qi Tongwei called out quickly.

"007, what's going on?"

now.

Wan Liyun in the cabin was very experienced and he quickly regained his composure.

While starting the emergency response, he replied:

"The plane was struck by lightning and the right engine stopped."

Hear this.

Zhao Mengsheng and the others were nervous, but in order not to disturb Qi Tongwei, they kept silent.

Then, Wanliyun continued:

"Failed to restart the engine, altitude dropped, I'm trying to figure out what to do."

Qi Tongwei knew what engine shutdown meant.

If not handled properly, the aircraft will enter a spiral stall and it will be difficult to rescue it.

Fortunately, he designed the plane and was familiar with many things.

He quickly said to Wan Liyun:

"007, try your best to stabilize the plane and reduce the speed of descent."

"clear."

After all, Wanliyun has rich experience in flight tests, and the aircraft's aerodynamic layout is excellent.

With the power of one engine, the plane quickly got out of the spiral dive.

"The plane's descent has slowed down," the person next to him reported.

"Report, the plane has been temporarily stabilized."

After hearing this, Qi Tongwei breathed a sigh of relief.

"007, try restarting the engine in one minute."

"understand……"

Time passed second by second, and everyone felt as if every second was a year.

Qi Tongwei looked at the time.

If the restart fails, the aircraft can only rely on one engine to land.

It also means that the first test flight failed.

One minute later.

Wanliyun tried to restart the engine.

At the moment of starting, the right engine reignited successfully.

The alarm in the cabin was deactivated.

"Report, the right engine started successfully."

"Very good……"

Upon hearing the news, everyone in the tower control room couldn't help but cheer.

Qi Tongwei finally breathed a sigh of relief.

So he instructed: "Okay, you return and land now."

Unexpectedly, Wan Liyun said, "I want to try again. The plane is in good condition now."

Wan Liyun, a top-class test pilot, was unwilling to give up just like that.

Through the familiarization just now, he has already figured out the temper of his new partner.

This is a good partner you can trust.

"Please believe me, Commander. This time we will succeed."

Qi Tongwei had no choice but to look at Zhao Mengsheng and the others.

They also understood that giving up was not in the character of the Xia soldiers.

So he nodded.

Qi Tongwei said: "Okay, you are allowed to continue the test flight."

"Thank you, Chief..."

After saying that, Wanliyun flew the fighter plane again and began to climb at the maximum speed.

"Good buddy, it's up to you."

Soon, we approached the cumulonimbus clouds again.

Wanliyun will increase the power to the maximum.

Everyone in the control room kept a close eye on the altitude.

"6000...6500...7000"

"Report, 007 has successfully passed through the cumulonimbus clouds, and everything is normal with the aircraft."

Suddenly, applause broke out in the control room.

After passing through the clouds, the sky is clear.

Wanliyun began to fly the plane, piercing the sky like a sharp arrow.

Soon, the altitude exceeded 10,000 meters.

When we tested old models in the past, the engine would run out of power as soon as the altitude exceeded 10,000 meters.

And now this plane seems to still have endless power.

This made Wanliyun very excited.

Then continue to push the accelerator to fly upwards.

Everyone watched as the numbers on the screen continued to rise rapidly.

Soon we reached 20,000 meters.

You know, 20,000 meters is the upper limit of the altitude of the United States' most advanced stealth fighter.

Zhao Mengsheng asked, "Can it get any higher?"

Qi Tongwei said confidently: "The maximum ceiling we designed is 25,000 meters."

Twenty-five thousand meters is already far ahead of the United States.

After the aircraft's altitude exceeded 20,000 meters.

Wanliyun felt that the climbing speed slowed down due to the thin air.

But still full of motivation.

Soon, it reached a maximum altitude of 25,000 meters.

“It worked…it worked.”

The technicians cheered.

Qi Tongwei then called out:

"007, how's the plane doing?"

Wan Liyun replied, "Excellent, I request to continue climbing."

Want to continue?

Zhao Mengsheng and the others are already very satisfied. Isn’t this the limit?

You have to know that the higher you go, the greater the test on the aircraft.

Because the air is thin, the engine may stall due to insufficient air intake.

However, Qi Tongwei knew that the figure of 25,000 was very conservative.

So he said decisively: "I agree."

Li Zhenxiao was afraid of accidents and advised:

"I don't think it's necessary. This data is already the best in the world."

Qi Tongwei said, "Since we are trying, let's try it to the limit."

"I agree." Zhao Mengsheng immediately said:

Then Wanliyun began to continue climbing.

It was not until the aircraft climbed to an altitude of 30,000 meters that an overload alarm was issued.

He knew that no one could match this data.

For safety reasons, Wanliyun reported:

"Report to the tower, the aircraft has an overload alarm at an altitude of 30,000 meters."

"Requesting descent."

"Agree." Qi Tongwei replied immediately.

In an instant, warm applause rang out again in the control room.

The altitude ceiling of 30,000 meters means that in the future we can drop enemy aircraft from the sky over their heads.

Soon, several other maneuvers were completed smoothly.

"Reporting to the tower, flight 007 has completed its test flight and is requesting to return."

"You can return."
