The Immortal Warrior: From Reverse Engineering to Forging Swords for the Country

Chapter 234 The Distress of the Test Pilot [Request for Full Order and Data]

Gao Linfeng was very happy when he heard this.

He thanked her repeatedly, saying, "Thank you, Comrade Guanyuan."

"I will never cause trouble to the organization."

Two days later, the weather in Shanghai was good, the sun was shining, and there was almost no wind.

This is the time selected for the first test flight of the Y-20.

At 9 o'clock in the morning, Zhang Zhipeng and others came to the test flight field together.

The staff is doing the final check.

Zhang Zhipeng, Qiao Guanyuan and others were standing near the plane.

The test flight team involved in the test flight is ready.

Although Gao Linfeng is just an ordinary member of the flight test team, his work enthusiasm is the highest.

He even started assisting ground staff with various inspections.

The captain of this test flight was named Zhao Peng.

Zhao Peng is also an experienced test pilot.

At the beginning, he participated in various modifications of the Y-8 and the test flights of the early warning aircraft.

Zhao Peng and Zhang Zhipeng are also very familiar with each other.

The two had dealt with each other more than once.

Just two days after these test pilots arrived in Shanghai, Zhang Zhipeng personally provided comprehensive training to these test pilots.

The Y-20 is a rare large aircraft.

There have also been a lot of upgrades and simplifications in terms of control.

To describe it in one sentence: It opens better.

But there are also more electronic devices.

This requires pilots to familiarize themselves with the aircraft in advance so that they can better fly and handle emergencies.

Finally, all preparations before the test flight have been completed.

The test flight team is about to board the plane to start the first flight of this large aircraft.

Zhao Peng led all members of the flight test team to salute and ask for instructions from Qiao Guanyuan.

Qiao Guanyuan was also a little nervous at the moment.

He immediately issued an order to carry out the first test flight mission immediately.

Zhao Peng led the test flight team towards the boarding gangway.

Their eyes were determined and everyone was excited inside.

Zhao Peng and the test flight team boarded the plane and took their positions in the cockpit.

Instructions continued to come from the ground tower.

The plane started up and made a roar.

However, the sound of the engine is not that loud and can be called quiet.

Gao Linfeng is not the captain, he just does some auxiliary work on the plane.

But he was still very excited.

He knew that he was actually witnessing history!

At that time, the Y-10's fully loaded flight weight reached 110 tons, which was already considered a large aircraft.

But now, the fully loaded flight weight of this Y-20 has reached more than 270 tons!
It is more than twice as big as the Y-10.

Currently, only Aramco and Russia can manufacture large transport aircraft.

Gao Linfeng felt excited when he thought that his country would soon join the ranks of countries that could manufacture giant aircraft.

Being a test pilot is a very dangerous job.

Especially for models that are testing flights for the first time, there are many unexpected risks.

Zhao Peng, Gao Linfeng and others had already written their suicide notes when they were selected for the first test flight.

But none of them were afraid.

An order came from the ground for the plane to take off.

Zhao Peng immediately started to control the plane and brought it to the runway.

After reaching the runway, he began to accelerate. And it was violent acceleration!
Although the Y-20 is huge in size, it accelerates very quickly and is particularly powerful.

"The power is amazing! It's so strong." A test pilot said with a smile.

The plane glided on the runway for more than 700 meters, which was less than 10 seconds, and its speed had reached over 300 kilometers.

Now, the plane can be controlled to take off.

Zhao Peng decisively began to pull up the passenger plane.

The nose of the huge passenger plane tilted up and it quickly flew into the air, climbing at a very fast speed.

"The control feeling is really great. This is the plane with the shortest taxiing distance I have ever flown!" Zhao Peng said to his companions a little excitedly.

Gao Linfeng smiled and said: "It took a total of 16.37 seconds to slide, and the sliding distance was 788.3 meters!"

"Such a huge aircraft can take off from such a short runway. It is much better than similar transport aircraft of the Amei family!"

According to available data, Aramco's C-17 transport aircraft can take off after taxiing for more than 900 meters on an unpaved runway.

Now, the Y-20 can take off after taxiing for less than 800 meters. This alone shows that the engine performance of this aircraft has surpassed that of similar aircraft of Aramco.

There was warm applause and cheers in the cabin.

Because, this is what is called a good start!
On the ground, Zhang Zhipeng and Qiao Guanyuan stood side by side, watching the domestically-made large aircraft climbing.

Zhang Zhipeng also has a walkie-talkie in his hand, and he is ready to communicate with the test pilot on the plane at any time.

Judging from the current situation, the test flight is going quite smoothly.

The aircraft performed very well in all aspects.

Qiao Guanyuan looked up at the Y-20 that was getting smaller and smaller in the sky, with an expression of both excitement and nervousness on his face.

"Comrade Zhipeng, this takeoff is excellent!"

Zhang Zhipeng smiled and nodded, saying, "It should be better than other large aircraft of the same type."

Generally, large civil airliners need to taxi for at least 2000 meters before they can take off.

Some even need to glide for more than 3000 meters before taking off.

For a large aircraft like the Y-20, it can take off after taxiing for less than 8 meters, which is absolutely excellent.

Of course, this doesn’t mean that the shorter the distance the aircraft taxis for takeoff, the better.

But for military transport aircraft, being able to take off using a shorter runway is definitely an advantage.

Short runway takeoff is a capability that military transport aircraft must have.

Qiao Guanhua added: "The climbing speed is also quite fast, which shows that its engine is still very powerful."

The Y-20 uses four engines, and the thrust of a single engine can reach 4 tons.

There is naturally no problem with power.

Zhang Zhipeng said: "It still depends on the subsequent full-load flight results."

"But overall, I think that if its test flight is successful, it will definitely be a huge breakthrough for my country's aviation industry."

"It is of great help to our army's long-distance maneuvers."

Qiao Guanyuan said with emotion: "After the Y-10 was discontinued, I felt that we might never have the opportunity to develop in the design and construction of large aircraft again."

"I didn't expect that thirteen years later, our aircraft that is even larger than the Y-10 would have already taken to the sky."

Aviation industry, this is definitely Zenith technology.

It is the brightest jewel in the crown of technology advocated by the Lizard Party.

Currently, only Europe, the United States and Russia have the ability to produce and develop large aircraft.

In terms of civil aviation, only Europe and the United States monopolize this business.

This business is worth as much as two to three hundred billion dollars every year.

Of course, civil aviation is just one aspect. If military aircraft are included in the military industry, the market size will probably more than double.

This is definitely a super industry.

Back then, Jiaoben once dreamed of making a difference in the field of large aircraft. Unfortunately, it was impossible for the dog owner to allow his dog to develop such a high-tech industry.

The foot basin made several attempts to apply it to large aircraft, but all ended in failure.

Zhang Zhipeng smiled and said, "We will have better planes in the future! Yes! My ideal is to occupy a place in the field of civil aviation and cut a big piece of the pie."

"Of course, it's too early to say this now. We still have to wait and see how the test flight of our first large aircraft goes."

In the sky, Zhao Peng was controlling the Y-20 and had already flown to an altitude of over 3 meters.

Here, strong convective air is relatively less.

It took only about 3 minutes from takeoff to climbing to an altitude of 9 meters.

Zhao Peng felt that if he stepped on the accelerator a little more, he would probably be able to move up even faster.

The test pilots responsible for different tasks in the flight test team are also busy.

At an altitude of 3 kilometers, the plane was in good flying condition.

"Now, let's try the maximum ceiling of this aircraft!" said Zhao Peng.

He began to continue to slowly increase the altitude of the plane.

4000 m.

5000 m.

6000 meters...

The plane continued to rise.

You know, the higher you fly, the thinner the air is and the lower the temperature is.

The greater the test for the aircraft.

This is a test of the aircraft's overall structure as well as its engines.

Zhao Peng climbed very quickly at the beginning, but when he reached an altitude of 10,000 meters, he became more cautious.

However, it seemed to him that there was no problem for the plane to continue climbing, and it seemed very easy.

The stratosphere is generally above 1.1 meters.

Here, there is basically no strong convective climate on Earth, and rain, snow, thunder and lightning have all been left behind.

Because the atmosphere is thin, it can basically absorb no heat, so the lowest temperature can even reach minus 50 degrees Celsius.

If there is a defect in the aircraft engine, various failures will inevitably occur.

Zhao Peng flew for a while at an altitude of 10,000 meters. Everything was stable, the engine was in good condition, and the aircraft's electronic systems were operating normally.

At this time, Zhang Zhipeng asked about the situation in the air through the radio.

Zhao Peng quickly reported the current flight parameters. Zhang Zhipeng smiled and said, "Everything looks good. Now, let's try to reach the highest flight speed."

Zhao Peng immediately responded: "Received the order! We will start the test immediately!"

Zhao Peng began to step on the accelerator.

The plane reacted quickly and began to accelerate rapidly.

The members of the flight test team looked at the data displayed on the LCD screen nervously.

The flying speed before acceleration was about 570 kilometers per hour.

After accelerating for 5 seconds, the speed rises to 900 kilometers per hour.

Zhao Peng felt that the speed seemed to be still increasing.

Moreover, the potential of the engine seems to have not been fully released.

Zhao Peng contacted the ground via the radio and asked whether to continue sprinting on the highway.

Zhang Zhipeng replied to Zhao Peng that this engine can reach supersonic speed and can test the engine's limits.

As mentioned earlier, the WS-8 engine led by Zhang Zhipeng can adjust the bypass ratio.

The smaller the bypass ratio, the less air enters, the more aviation fuel is burned, and the engine sprays out high-temperature and high-pressure gas flow to propel the aircraft.

This will make the plane go faster.

Of course, fuel consumption will also increase rapidly.

Zhao Peng stepped on the accelerator again, and he felt that all four engines began to roar.

The speed also began to soar again.

950 kilometers.

1000 kilometers.

1100km…

It kept rising to nearly 1300 kilometers per hour, and then it seemed to hit the speed bottleneck...

"1294 kilometers per hour!"

"This has exceeded the speed of sound!"

Gao Linfeng shouted excitedly.

The speed of sound is approximately 1224 kilometers per hour.

Therefore, this huge transport plane has indeed exceeded the speed of sound.

This is an astonishing statistic.

The maximum speed of Aramco's C17 transport aircraft is only over 800 kilometers.

Zhao Peng held his breath as he looked at the aircraft's conditions displayed on the LCD screen.

All is well!
This huge aircraft flies very smoothly at supersonic speed.

Zhao Peng suppressed his inner excitement and reported to the ground the maximum speed the plane had reached.

His voice came from the walkie-talkie in Zhang Zhipeng's hand.

Everyone around Zhang Zhipeng exclaimed in surprise.

"so fast!"

"Can such a large plane fly at supersonic speed?"

"The WS-8 engine is really powerful! How does it manage to fly smoothly at both high and low speeds?"

Aircraft engines generally come in three types: turboprop, turbojet and turbofan.

Aircraft that fly at hypersonic speeds basically use turbojet engines.

Turbojet engines use high-temperature and high-pressure gas flow to propel aircraft flight.

Its flying speed can reach astonishing levels.

For example, Russia's MiG-25 can reach a maximum speed of Mach 3.2, which is 3.2 times the speed of sound.

However, turbojet engines are very fuel-intensive and have poor low-speed performance.

In the 2s and s, passenger planes equipped with turbojet engines could fly at speeds of more than twice the speed of sound.

For example, Giant Bear's Tu-144 passenger aircraft can fly at a maximum speed of Mach 2.35.

However, the economic effect of hypersonic flight is too poor.

As a result, hypersonic passenger aircraft were gradually eliminated.

The most amazing thing about the Y-20 is that it can fly both at low speed and at supersonic speed.

Moreover, the speed of both flights was quite stable.

This is a super rare performance.

Zhang Zhipeng is quite satisfied with the performance of WS-8.

"Now, you can test the maximum ceiling." Zhang Zhipeng issued an order.

Zhao Peng replied: "Got it!"

He immediately began to slowly increase his altitude while maintaining an extremely high speed.

Rising little by little from 1 meters.

Eventually its height reached an astonishing 1.4 meters.

This height also surpasses Aramco's C17 transport aircraft.

However, this does not seem to be the limit of the Y-20.

"Comrade Zhipeng, the plane is operating normally at an altitude of 1.4 meters. It is performing steadily and the engine is running well." Zhao Peng reported to Zhang Zhipeng.

Zhang Zhipeng nodded and said, "The project to be tested today has been successfully completed!"

"You can use up some more fuel and then choose to return!"

The Air Force bosses surrounding Zhang Zhipeng were all very happy at this moment.

You know, this is the first test flight of the Y-20!

In fact, the first test flight will not test so many items at once.

As long as it can fly and remain in the air normally, it will be considered a huge success!
And now?

The Y-20's first flight tested a short runway takeoff, and tested its maximum ceiling and maximum speed.

All aspects of the test performed very well!

This is just too exciting.

"Comrade Zhipeng, our Y-20 can be considered a great success, right?"

Qiao Guanyuan asked.

Zhang Zhipeng smiled and said, "It's a pretty good performance."

"But we still need to continue to do more flight tests."

"We must constantly discover and solve problems during the test flight!"

“Only in this way can we create a truly high-performance aircraft.”

There is still a lot of test flight projects to be done. An aircraft often has a long way to go from prototype to finalization to mass production.

Unless the aircraft performs perfectly from the beginning, there will be few major problems in all aspects.

This is the only way to put it into use quickly.

But airplanes are man-made, how can there be no problems?

It's normal to have problems, right?

The Y-20 is still flying in the air.

The test pilots had already relaxed a little at this time.

Zhao Peng is talking to Gao Linfeng.

"Comrade Lin Feng, you also test-flew the Y-10 back then, right?"

Gao Linfeng nodded and said, "Yes."

Zhao Peng asked again: "What was the situation when the Y-10 was first tested?"

Gao Linfeng said: "There are still many problems exposed."

"The most serious thing is that this aircraft has been plagued by various minor malfunctions."

"Its engine was also bad, it was weak and had problems more than once."

"But even so, it is still a major breakthrough for our aviation industry."

Gao Linfeng was very emotional.

Zhao Peng's question reminded him of his youthful years.

Zhao Peng said: "It was mainly because our industrial strength was not strong enough at the time and we were not good at making precision parts."

"More than a decade has passed, and our country seems to have been reborn!"

Gao Linfeng nodded and said, "Yes, everything has changed dramatically."

"Take the exterior design and workmanship of this aircraft for example, it is much better than the Y-10 back then!"

At the end of the test flight, Zhao Peng said to everyone in the test flight team: "Everyone think about it. If you find any problems, summarize them and feedback them to the designer and manufacturer."

Test flight is actually a process of finding faults.

Naturally, the more real problems that can be picked out, the better.

Only when all the problems and hidden dangers are solved can the aircraft become better and better, right?

The test pilots all fell into deep thought.

They were racking their brains to recall the problems that had occurred during the entire flight.

However, after thinking back, they found that they could not find any major faults.

The engine is powerful, the flight is smooth, the acceleration is fast, the take-off distance is short, and even the engine noise is well resolved.

Other features include good thermal insulation inside the aircraft and excellent air circulation.

The test pilots talked for a while and found that they were saying only positive things.

Zhao Peng was a little anxious: "It seems that we can't even raise a valuable question..."

Gao Linfeng said: "Comrade Zhao Peng, the problem cannot be forced."

"No means no, that's all."

"The questions we raise should all be related to flight and safety."

“The current test flight experience is perfect.”

"Let the experts raise other issues concerning the aircraft!"

Zhao Peng thought the same thing: as a test pilot, he had already completed his mission by measuring the aircraft's performance and other data.
