I am an industrial worker during the War of Resistance

Chapter 89 Is this what flying feels like?

"Master, is this what it feels like to fly?"

This is completely different from simulating on the ground; it feels so good.

The pilot, Zhu Xiuzhi, sitting behind Jiang Dacheng, watched the ground rapidly receding into the distance.

And the people on the ground, who had become almost invisible dots, and the trees.

And as I broadened my horizons, all I could see was the vast sky and the earth.

At this moment, he couldn't help but excitedly shout to Jiang Dacheng, who was focused on piloting the plane in front of him.

This trainer aircraft is equipped with headsets for communication between the front and rear pilots.

This is just a small function of the airplane's intercom.

The principle behind this communication is similar to what many people played as children: two people holding paper cups with a string attached to the bottom of the cups, shouting to each other.

Their call was a wired call.

When Zhu Xiuzhi's extremely excited shouts came through the earpiece, Jiang Dacheng said, "Yes, this is what it feels like to fly."

Pay close attention to the movements of the control stick and rudder pedals in front of you, as well as the aircraft's status.

Our control stick and pedals are linked, so you can clearly feel how the aircraft is flying under our control.

"Yes, Master."

Modern headsets do not yet have the noise reduction and sound pickup features that we see in later models.

Although the microphone that is connected to the earcups also uses a design that maximizes directional sound pickup.

However, the noise inside the cockpit can still be heard through the over-ear headphones.

But this is still much better than not having headphones at all.

At least they don't have to shout loudly in the cabin and can't hear what others are saying.

Even though the plane had a fully enclosed cabin, there was still a raging V8 engine not far in front of them.

Those eight exhaust pipes, which only have flame suppressors and no mufflers, would also transmit the sound of explosions from the combustion chamber when they spewed out exhaust gases.

Even with double-layered tempered laminated glass and cabin sealing strips, noise cannot be completely prevented from intruding.

On piston aircraft engines, almost no one installs a muffler on the exhaust pipe because it would result in a loss of five to ten percent of the power.

The aircraft's altimeter, displayed on a vacuum diaphragm barometric altimeter, showed a pointer pointing to a sea level of two thousand meters.

This altitude is the low-altitude level flight test altitude requested by Chen Changzai.

Moreover, this altitude is within the clearest communication range of the aircraft's ten-kilometer radio transmitter.

At this moment, Jiang Dacheng shouted into the walkie-talkie that was always on: "Tower, tower, this is Eagle One, this is Eagle One."

The aircraft is currently in good condition.

The engine showed no surge, no abnormal noise, and ran smoothly.

The aircraft was handled well, reacted promptly, and did not shake.

I have now climbed to an altitude of 2,000 meters and request a level flight test.

At this moment, the leaders on the ground and Chen Changzai were all holding binoculars, watching the plane in the sky that was constantly climbing higher.

After receiving the call from Eagle One, Chen Changzai picked up the microphone with a small loudspeaker on the walkie-talkie and shouted, "This is the control tower, this is the control tower."

The Eagle One is permitted to conduct level flight tests at cruising speed.

The test distance is the turnaround point 30 kilometers due north. After arriving at the turnaround point, return to the starting point with a large turning radius.

To reiterate, Eagle One is permitted to conduct level flight tests at cruising speed.

The test distance is the turnaround point 30 kilometers due north. After arriving at the turnaround point, return to the starting point with a large turning radius.

Eagle One, please respond. (Repeated "Repeated ")

This so-called control tower is actually just a ground-based radio telephone connected to a 15-meter-high antenna.

Now Chen Changzai has also taken on the role of a tower controller.

After all, among the tower controllers being trained, none of them understands this aircraft better than Chen Changzai.

Furthermore, they also need to establish four radio communication observation points within a 30-kilometer radius north of the airport for relay communication.

Ensure the aircraft is within their line of sight and communication range.

This is why modern piston-engine aircraft fly slowly.

If it were a jet plane from later generations, that 30-kilometer distance wouldn't even be enough for them to fly a few miles.

"Eagle One received, Eagle One received."

The target is a turnaround point 30 kilometers due north. The aircraft is cruising at level speed and making a large turnaround radius.

After receiving the tower's order and repeating it, Jiang Dacheng, following the direction of the onboard compass, began to fly due north at a cruising speed of 300 kilometers per hour toward the northward turnaround point.

Every few minutes, Jiang Dacheng would contact the ground communication point set up between the airport and the turnaround point to ensure that he had not deviated from the course.

When Jiang Dacheng saw the large circle on the ground ahead, made of wooden boards painted red, with a large red cross inside the circle.

He knew he had reached the turning point.

After re-establishing contact with the ground liaison point, Jiang Dacheng began a large-radius horizontal turn and then flew south again.

When he returned to the airspace above the airport, he reported to the ground control tower that everything was normal.

Under the command of Chen Changzai on the ground, the altitude test began.

When Jiang Dacheng piloted the plane to climb to the set service ceiling of 7,000 meters.

Jiang Dacheng began to circle over the airport.

At this point, he can't fly too far.

Because the maximum communication range of the walkie-talkie on his plane, even under the best conditions, is only ten kilometers.

If it flies too far, its communication performance will be greatly affected.

"Control tower, control tower, this is Eagle One. I have now ascended to an altitude of 7,000 meters and am currently performing a horizontal circle."

The plane is now operating normally and there is no shaking.

The engine is working normally and there is no surge.

Awaiting further flight instructions.

"Tower received, tower received."

"Hold the aircraft horizontally for three minutes, then begin the descent."

"Eagle One understands."

When Jiang Dacheng climbed to this altitude of 7,000 meters, he had already put on an oxygen mask.

However, he wasn't breathing pure oxygen, but rather oxygen-enriched air with a concentration of 40%.

The normal oxygen content at ground level is 21%.

People only inhale pure oxygen for short periods of time during emergency situations. If a person inhales large amounts of pure oxygen for a long time, they will suffer from oxygen poisoning.

As for producing small amounts of oxygen, Chen Changzai has already solved this problem using chemical methods.

It just can't be used in industrial applications because the quantity is too small.

However, it is sufficient for medical use and for use by air force pilots.

Although industrial-grade oxygen compressors already exist abroad, Chen Changzai doesn't have one.

Moreover, that compressor requires high precision and has a relatively complex manufacturing process.

Although our own laboratory has already developed a laboratory-grade compressor for the production of synthetic ammonia.

However, there is still a long way to go before we can mass-produce industrial oxygen. These things cannot be accomplished overnight.

We can only take it one step at a time.

After circling at an altitude of 7,000 meters for three minutes, Jiang Dacheng began to pilot the plane down to a lower altitude.

He kept the plane's nose aligned with the runway marked by two white lime lines on the airport.

Jiang Dacheng then slowly began to ease off the accelerator, reducing speed and altitude.

After the plane approached the airport and its tires touched the ground, it taxied for more than 300 meters before slowly coming to a stop.

This test flight, whether it was takeoff or landing.

Jiang Dacheng followed Chen Changzai's instructions and set the safe distance to the maximum.

If the permitted takeoff and landing distances are followed, this length is not necessary.

According to Chen Changzai's calculations, the aircraft only needed a takeoff distance of seventy to eighty meters.

A landing distance of 200 to 300 meters is sufficient to meet the landing requirements.

With the help of ground staff, Jiang Dacheng and Zhu Xiuzhi disembarked from the plane using the ladder.

Because the place where the plane landed was not far from where the leaders and Chen Changzai were waiting.

So when Jiang Dacheng and Zhu Xiuzhi got off the plane...

The leaders and Chen Changzai had already gathered around.

Jiang Dacheng and Zhu Xiuzhi first saluted the leaders and Chen Changzai.

Jiang Dacheng said, "Reporting to the leaders, reporting to Director Chen, Jiang Dacheng and Zhu Xiuzhi have completed the first test flight of the Eagle No. 1 aircraft. Please give instructions."

At this moment, Chen Changzai took a step back, clearly giving up the position of questioning Jiang Dacheng and the others to the tall leader and other leaders beside him.

Anyway, he's not in a hurry to ask about data.

The leaders have a lot to do, let them go first.

The tall leader glanced at Chen Changzai, smiled, shook his head slightly, and said nothing.

Then he extended his hand to Jiang Dacheng and Zhu Xiuzhi, and said while shaking hands with them, "Comrades Jiang Dacheng and Zhu Xiuzhi, you two have worked hard. How did it feel to fly in the sky this time?"

We were on tenterhooks watching from below.

Especially you, Comrade Zhu Xiuzhi, you're a young comrade, this is your first time flying in the sky, weren't you scared?

Is training in the air different from training on the ground?

Jiang Dacheng began by saying, "Reporting to the leader, our test flight this time was a great success."

This plane is excellent; it's better than any plane I've ever flown before.

I feel it's even better than the Italian Fiat fighter jets I've flown.

Although I have never flown the Hawk III and Boeing 281 fighter jets that the bald guys bought.

But I feel that if we were to meet on the battlefield, I'm absolutely confident I could shoot them down from the sky.

The tall leader and the other leaders around him nodded in satisfaction after hearing this.

The kind-faced leader then said, "Comrade Dacheng has the skills, the courage, and the ability. I believe in Comrade Dacheng; he can not only shoot down the bald guy's plane."

Even if we encounter Japanese planes, we can still shoot them down.

Jiang Dacheng then said loudly, "Please rest assured, leader, Jiang Dacheng guarantees to complete the mission."

The leaders all laughed heartily and said "good" after hearing this.

At this moment, the tall leader looked at Zhu Xiuzhi and said, "Comrade Zhu Xiuzhi, how did you feel this time? Were you scared in the sky?"

Zhu Xiuzhi, who was only nineteen years old this year, said shyly, "Reporting to the leader, I am not afraid."

I feel great when I'm flying in the sky.

Flying in the sky is a completely different experience from being on the ground; it feels wonderful.

It's like standing on the highest mountaintop, looking so far ahead.

I could vaguely see the Yellow River. And it was flying in the sky, flying incredibly fast.

We flew over the 30-kilometer distance in no time.

If you were to run on the ground, it would take at least half a day to run.

This feeling and speed are completely imperceptible on the ground.

It can be summed up in one word: good.

After Zhu Xiuzhi finished speaking, the leaders looked at the young and inexperienced boy and all laughed good-naturedly.

The tall leader then said, "Comrade Zhu Xiuzhi is a brave young comrade."

I am certain that I will become an excellent pilot in the future.

But courage alone is not enough; you also need to learn more about flying.

More training is needed.

Only in this way can we defeat our enemies.

"Yes, I will definitely learn more about flying and train harder to resolutely defend our airspace."

We must resolutely annihilate all invading enemies.

"Well said, Comrade Zhu Xiuzhi is right. Each of us needs to study more and train our skills diligently."

In this way, we can resolutely annihilate all invading enemies.

After the leaders finished their greetings to Jiang Dacheng and his team, Chen Chang asked Jiang Dacheng, "Comrade Dacheng, how did you feel about the engine's response speed during this test flight?"
How does it feel to control the aircraft as a whole?
When you are controlling an airplane, do you feel that your hands are smooth?
How responsive is the aircraft?

Is there any intermittent tremor or stiffness?

Jiang Dacheng then said, "Reporting to Director Chen, during this test flight, I felt that the engine's response was very sensitive."

The engine responds very quickly every time you accelerate, and the acceleration is very smooth without any jerking.

The engine's power is very stable when turning and climbing.

There was no wheezing or sluggishness.

No engine vibration or unnatural shaking of the aircraft was detected throughout the entire flight.

This aircraft can be described as a very successful one.

After listening to Jiang Dacheng's words, Chen Changzai nodded and said, "Well, it seems we've kicked things off with our first move."

However, the test we are conducting today is only a preliminary test.

It simply means that the plane can fly.

It can fly out of the basic data we set when we originally designed it.

However, we still have many more training courses to complete in the next two weeks to a month.

Only if it passes all these flight test assessments can it be considered a preliminarily qualified aircraft.

"Yes, we will definitely test the full flight performance of this aircraft during future test flights."

"It will definitely bring out all its best features," Jiang Dacheng said confidently.

You could tell from his tone that he really liked the plane.

For a pilot who once soared through the skies.

After not having the chance to touch an airplane for several years, they now have the opportunity to return to the skies.

This was the happiest thing in his life that he could feel.
