At this time!

The large ducted thrust aero engine in front of you is like a dragon roaring!

This violent energy poured down, and even the entire test site began to resonate a little!

The fan is running at an ultra-high speed of tens of thousands of revolutions per minute, constantly bursting out with powerful thrust!

Even if you can't see the specific performance, just look at the inhaled air and the terrifying trembling!

Everyone can intuitively feel how much thrust this large ducted engine has!

It's just that because there is no afterburner, there is almost no tail flame in the tail of the engine!

After all, for a large ducted transport aircraft, supersonic cruising is not required at all in conventional situations!

Time passes by second, and this engine is smoothly outputting the specified power!

On several screens, thousands of pieces of data are constantly being gathered!

Staring at their nervous gaze.

Seeing a statistic that had been counted, Jiang Chen said with a smile:

"The engine output is very stable, and its error value is up to standard!"

"Even smaller than the theoretical Standard Model!!"

"Sustained output capacity, always within the specified range!"

Even if it was him, his heart was suddenly relieved!

For a large ducted engine, its stability and continuity are particularly important!

It is the key to determining the range of capabilities of the transport aircraft, and even no less than thrust and endurance!

The words just fell!

Suddenly, the entire research institute was noisy!

What this means, all researchers know better!

"Are we going to succeed???

"Great!! Normal output power is half the battle! ”

"There are no problems with basic testing and completeness, everything is in normal condition!"

"The rest is up to the engine stress test and performance data."

"The thrust performance of this scene alone is not bad, it depends on other aspects!"

"Even if it's a little bit. That's enough for the current transport plane."

Several academicians said with red faces, unable to suppress the excitement in their hearts at all!

That's what they're most desperate to get!

After all, this is the first full technical verification, and even if the performance data is a little less, it is not surprising

As long as the engine is in the pressure test and there are no accidents, the performance can be improved in the subsequent research and development.

However, if there is a problem with the power output and smoothness, it means that there is a problem with the basic development of the entire engine!

It may even require a redevelopment from the underlying architecture, which can be more serious than the lack of performance!

After a while.

This large ducted aero engine, which had been roaring for dozens of minutes, slowly stopped!

This means:

The performance test and the stress test have been completed, and the accurate results have been measured!

Looking at this scene, everyone was even more breathless, and their eyes were firmly locked on Jiang Chen.

Hoping to get a number that they have been satisfied with so far!

"Its thrust data is," Jiang Chen said, staring at the data on the screen.

In an instant, the atmosphere of the audience almost froze.

"On continuous performance predictions."

"The 46.5 tonnes figure was reached, and the thrust performance exceeded the experimental target! Qualified! ”

Jiang Chen's tone was full of surprise!

He originally estimated that it was only 45 tons of thrust, but now it can exceed 1.5 tons of thrust.

After thinking about it carefully, it should be the memory metal that played a role in the large duct fan.

Hear this.

In an instant, everyone couldn't react for a long time, as if they were at a loss!

"How much? 46.5 tons?? ”

"It's not a joke!?

"Not only did it meet the expected figures, but even slightly exceeded them?"

"Hey, that's a whole 1.5 tons more than the technical specification!"

"This thrust performance, if you put it on a transport plane."

Several academicians said in a shocked tone, with disbelief on their faces.

Just now they are all mentally prepared for a thrust of only 43 tons, 42 tons or even less.

As a result, I didn't expect it to reach 46.5 tons!

Don't underestimate this is only a 4% increase in thrust, if a transport aircraft is equipped with four engines!

Then the thrust of the comprehensive ratio is increased by 6 tons, and the carrying capacity can even be increased by more than 10 tons! (The specific lift is not roughly calculated.) ）

"Large ducted engine with 46.5 tons of thrust"

"And that's just the thrust performance, we're not a success yet!"

"What are the other properties of Chief Jiang Gong?"

Lu Yuanhang forcibly calmed his tone, but the trembling hand showed the unrest in his heart.

You know, this is a big ducted engine, not a small one bypass engine!

In other words, it has no afterburner, and there is no so-called afterburner maximum thrust!

This means that it is equivalent to a single engine of a fighter jet, and its military thrust can reach 46.5 tons, how terrifying is this?

The thrust of this engine is half the thrust of the Eagle Sauce C-5 transport aircraft!

In terms of performance, it is more than 1.5 times more than 1.5 times that of the TF39 turbofan engine of the C-5!

In the face of Lu Yuanhang's inquiry, he glanced at the latest data on the screen!

Jiang Chen continued to speak:

"It's bypass ratio to. Compressed air ratio: The theoretical value of reaching the standard did not exceed expectations! ”

"In this respect, meet the qualification requirements!"

Hear this.

Everyone in the entire research institute was not surprised this time.

After all, they have carried out many rounds of technical verification on the duct ratio, compressed air ratio, etc.

Each time, the corresponding adjustment will be made to achieve the most ideal effect!

If this performance data is abnormal, then it is abnormal!

"How much has Jiang's fuel consumption been reduced?" Lu Yuanhang asked.

This is the question they want to know the most at the moment, and it is also the most urgent thing!

Meet everyone's eyes!

After Jiang Chen pulled a few pages of data, he flipped through these important data.

"Compared with EPD-20, the average fuel consumption rate has decreased by more than 50%!"

"Estimated average fuel consumption rate: 0.05!" (Fuel load per kilogram, kg/(daN·h))

"And its cruising range, according to theoretical predictions, in the case of equal lift data!"

"The endurance is more than 45% higher than the current Y-20"

Looking at this data, Jiang Chen nodded with satisfaction.

Whether it is fuel consumption or cruising range, it almost slightly exceeds the theoretical data!

Even when the engine thrust is increased to 46.5 tons, the fuel consumption rate can still be maintained at 0.05.

Excluding some turboprop aircraft, this can be said to be the world's high-thrust engine, the lowest fuel consumption rate!

It is even more than twice as lower than the Y-20!

And now.

At that moment, the entire institute fell silent.

It seems that everyone is shocked by this data and is speechless!

After a while.

In an instant, the audience seemed to be boiling, and the excitement in my heart could no longer be restrained!

"We've developed it! The large duct and high-thrust engine has been successfully developed! ”

"That's a terrifying stat, isn't it?"

"0.05 average fuel consumption rate, reducing fuel consumption by 50%. What kind of outrageous data is this? ”

"I can't believe it's an engine that I developed. It's incredible! ”

"The most important thing is the endurance, which is 45% higher endurance with the same lift?"

Several academicians of the Academy of Aviation said excitedly!

Originally, the endurance of the Y-20 was close to 8,000 kilometers, but after the upgrade, it was close to 11,600 kilometers!

This is still the conclusion of the data with the same thrust and carrying capacity!

And the thrust increases, the carrying capacity increases, then the fuel carried will naturally increase accordingly!

Then its actual endurance can easily even exceed 15,000 km!

"This if"

"Use a better EPD-20 upgrade as a large ducted engine!"

"Doesn't that mean that its performance will skyrocket??"

Lu Yuanhang seemed to have thought of something, and muttered to himself!

The words just fell!

Everyone was stunned and couldn't react for a long time!

They couldn't have imagined that with the new ultra-high strength alloy and EPD-20 upgrade technology!

What will be the performance of this large ducted engine?

How much range and thrust can it reach? Sixty tons? Or seventy tons? 20,000 km range?

I'm afraid it's not going to run towards the goal of the space carrier, but it's heading out!!

Now.

After Jiang Chen announced the success of research and development!

Lin Congli immediately reported this major R&D achievement!

Only a few hours passed, and an urgent order was sent directly to the Academy of Sciences!

Lin Congli stared at all the R&D personnel.

In the most solemn and serious tone, slowly read the message in his hand.

"The above requires our Academy of Sciences!"

"Mass production of large ducted engines as fast as possible!"

"The upgrade plan of the Y-20 transport aircraft will start immediately, and the major aircraft industry groups will be fully producing!!"

"Yes!" Including Jiang Chen, everyone responded without the slightest hesitation!

However.

Lin Congli did not pause, and continued to speak:

"This is just the first order from above, and there is a second below!"

"A new generation of transport aircraft - Kunpeng, the research and development plan has officially begun!"

"Any department, at all costs, unconditional cooperation!"

After hearing that the upgraded version of EPD-20 is changed to a large ducted engine, the performance is even more terrifying!

The decision above without hesitation.

This time, it is not only necessary to develop an upgraded version of the Y-20, but also to develop a next-generation transport aircraft.

"Guaranteed to complete the mission!!"

Lu Yuanhang and other academicians of the Academy of Aviation said impassionedly, with tears in their eyes!

How many of them have been looking forward to this day since they were young students!

Now, they're going to make that dream come true!

It is more than one billion people in China, a long-cherished wish that has lingered for hundreds of years!

This time, it is not only necessary to develop the world's strongest transport aircraft, but also to develop an unprecedented transport aircraft!

The transport plane named Kunpeng is a behemoth in mythology and thousands of miles in shape!

A few days later!

In the large duct engine research and development, as well as the Y-20 modification and upgrade plan, are in full swing.

The other side.

Inside a R&D and construction workshop.

The development of the Giant Gundam is also well underway!

"The Giant Gundam's Most Critical Problem!"

"It's finally settled"

"It's the last step away from the real development!"

Jiang Chen stared at the behemoth in front of him, which was more than ten meters tall, and was faintly excited in his heart!

Maybe it won't be long!

Not only can he fly a Gundam mecha, but he can also fly this giant Gundam that is more than ten meters tall!
