Thousands of meters in the air.
Li Jianfei drove the J-20 at full throttle and flying at a speed of Mach 3.2.
At this speed, the forward distance is more than one kilometer per second, and just ten minutes is enough to fly more than 650 kilometers!
However, even this is the case!
He looked at the engine efficiency and thrust data displayed on the instrument screen in front of him and was stunned!
They all wondered if they had seen something wrong?
"At this speed, the maximum thrust has not been reached yet??"
"This is already more than 35 tons of thrust."
"How much performance data can this upgraded new engine achieve?"
"Besides, haven't I already turned on afterburner for ten minutes? And I still have 40% fuel consumption?"
Li Jianfei's eyes widened, and his heart was filled with shock!
What's more important is that it has been nearly ten minutes since full thrust afterburner was turned on! ?
Fifth-generation aircraft such as the F22 and F35 will run out of fuel if they are pushed with full throttle for a few minutes at most.
Even maintaining full thrust for a long time may cause damage to the engine!
And this J-20, nothing happened at all? This is outrageous! !
After a while.
The J-20 landed slowly and stopped steadily on the runway.
"Chief Engineer Jiang's flight test mission completed!"
"This J-20 has all performance data normal and no abnormal conditions have occurred!"
Lu Yuanhang looked at the data report displayed on the computer.
"okay, I get it!"
Jiang Chen nodded and said, his eyes fixed on the rows of numbers.
This is the focus of this flight test!
The most important purpose this time is to test the upgraded new engine.
What kind of power can be exerted on the J-20, and what is its specific performance.
After all, no matter how many times they conduct wind tunnel experiments, etc., it is still not as real as a real aircraft test flight.
Looking at these performance data, Jiang Chen fell into thinking.
now.
Li Jianfei, who had just stepped off the fighter jet, asked impatiently:
"Chief Engineer Jiang, I want to know!"
"What is the maximum thrust of this new engine?"
"I had already driven to Mach 3.2 just now, and the engine efficiency has not even reached the limit."
With Mach 3.2 cruising for more than 10 minutes and a thrust of 35 tons, is it still not its limit?
So what kind of performance can it achieve? This is the question he wants to know most now.
Not only him, but also the pilots next to him pricked up their ears.
They are also very curious about how outrageous this new aero engine is!
Listen to these questions.
Jiang Chen said directly without thinking:
"After the upgrade of this new aeroengine, its thrust has been greatly improved!"
"The maximum afterburner thrust is 48 tons, and the military thrust is 33 tons!"
"Fuel efficiency is reduced by more than 20% year-on-year."
“The full-thrust afterburner duration has been increased by more than 40% year-on-year!”
In the recent aircraft test, there was almost no big gap between these theoretical data and actual performance.
only.
Jiang Chen just said these numbers.
In an instant, Li Jianfei and the other pilots were all stunned, with expressions of shock on their faces!
"No wonder."
"I just said, why did I feel that the J-20 was a little unable to hold up just now!"
"The maximum thrust actually reaches 48 tons??"
Li Jianfei muttered to himself in a daze.
With such huge thrust, the current J-20 simply cannot use 100% full power propulsion!
Otherwise, a structural failure of the body is very likely to occur!
So when it accelerates to Mach 3.2, the fighter jet cannot improve further.
"At a top speed exceeding Mach 3.2, a full thrust time of more than 10 minutes is maintained."
"More than 60% of the fuel capacity was consumed."
"General Manager Jiang, this data is much worse than expected."
Lu Yuanhang looked at these data and frowned.
Based on performance data estimates.
This sixth-generation aero engine should be enough to support 20-25 minutes of full propulsion.
But now, 60% of the fuel was consumed in just ten minutes. This is an error of more than 20%!
However, this data has just come out.
The pilot standing aside couldn't sit still! !
"With full push, can it last for 10 minutes?"
"Is this data bad? It only consumes 60% of fuel in 10 minutes."
"It seemed that it could only last for four or five minutes at most before? And if you turn on afterburner for a long time, the engine won't be able to sustain it."
"Captain Li, you have turned on the afterburner for the past ten minutes. Is there anything wrong with the aircraft engine?"
Several people suddenly took a breath of air-conditioning, it was so terrifying!
Most fighter jets can only support it for a few minutes at most when the throttle is fully pushed!
Then most of the fuel will be used up, and even forcing to continue pushing at full speed will only damage the engine!
This J-20 even propelled at full throttle for more than 10 minutes, consuming only 60% of the fuel, which is simply incredible!
"It should be that the J-20's other performance cannot support it."
"So this resulted in an additional increase in fuel consumption!"
Jiang Chen looked at this data and said thoughtfully.
It seems that not only the engine needs to be upgraded, but also the J-20
Unexpectedly, in the past, the engine was not worthy of the J-20, but now the J-20 cannot keep up with the efficiency of the engine?
After thinking carefully for a moment.
Jiang Chen said to Lu Yuanhang and others beside him:
"The engine performance is functioning normally, and the flight test of the J-20 is also very stable!"
“I think it’s ready for mass production and preliminary installation!”
As long as all aspects of the J-20 are upgraded to a large extent, the full power of this engine can be unleashed!
Even.
Produce and manufacture J-20 fighter jets using new alloy materials!
After Jiang Chen reported the test flight report and conclusions.
Only less than a few hours to go!
An order was issued from above!
There are only a few short sentences, but the tone seems to be filled with endless excitement!
"Go all out and mass-produce sixth-generation aero engines at all costs!!"
"Unconditional cooperation from any department!"
"Complete the goal of fully fielding the J-20 as quickly as possible!!"
More than a billion people have been looking forward to this moment for decades!
at the same time!
The Air Force also got an order at the same time!
Recently, a batch of J-20s will be upgraded and installed with new engines.
Even some J-15s and J-10s will be upgraded and put into service!
Let the original J-20 and J-15 pilots conduct flight learning tasks in advance and prepare for training after the upgrade!
All of a sudden!
Everyone in the entire Air Force started to get excited!
In an Air Force J-20 flight base not far from Yanjing!
"Is the J-20 going to be equipped with a new engine?"
"It should be to replace the newly developed turbofan-15 engine. This performance improvement is not small!"
"Compared with the current WS-10C, it is much better. The WS-15 is also a three-dimensional vector propulsion engine!"
Look at this document in your hand!
A strong smile appeared on the officer's face.
The J-20 is equipped with a brand new turbofan-15 engine. Although it is much faster than he expected, it is not too strange.
Let alone him, the top leader of the base.
Even many Chinese military fans know the news that the WS-15 is being developed!
"Old He, we can finally switch to the turbofan-15. The turbofan-10C we are currently equipped with!"
"It doesn't even have vector propulsion, it's worse than the engine on the J-10C!"
"In terms of mobility, it suffered a big loss!"
The man sitting next to him sighed and whispered to him.
In terms of air combat, whether a fighter jet has a vector propulsion engine may be the key to success or failure!
In recent years, even the J-10C has been equipped with the WS-10B with vector propulsion, but the J-20 is still not equipped with a vector propulsion engine!
Now, the wait has finally come!
Comes with this command.
There is also a document with two words "Top Secret" printed on it!
Lao He picked up the file, grinned and said:
"Lao Li, let's take a look at this J-20 with a turbofan-15 engine replaced!"
"What kind of performance can it achieve!"
Here is the replacement of a new engine and the upgraded performance data of the J-20.
Let them, the frontline military base commanders, understand in advance to prevent unexpected situations.
Slowly open the file.
Under the nervous gaze of the two people, several pieces of paper were revealed in front of them!
There is only a very brief introduction and data above.
They correspond to the performance of the engine and the improved performance of the fighter jet!
The first thing that bears the brunt is the bold black font printed on the first line!
[The upgraded engine model installed on the J-20 is: EPD-20 upgraded version! 】(epd = abbreviation for electromagnetic pulse deflagration.)
Then the second line is.
[J-15, J-10C, etc. will be gradually installed and upgraded. The engine model is: epd-20! 】(There is no version with material upgrades.)
Looking at the engine model displayed above, the two frowned.
"Isn't it going to be upgraded to WS-15 this time?"
"What type of engine does this EPD-20 upgraded version have?"
Rows of question marks popped up on Lao Li's head, and he was puzzled at all!
As the commander of a front-line air force base, he has never heard of this engine model?
Shouldn't the turbofan-15 engine be called WS-15?
When did China have an engine research plan with this serial number?
"Didn't the J-15 and J-10C just have their engines upgraded?"
"Why do we need to upgrade the equipment again this time?"
Lao He on the side was also confused and a little confused!
Even the J-10C and J-15, the main fighter jets, need to be replaced with EPD-20 aero engines? ?
Looking down, rows of performance data come into view.
All of a sudden.
"Hiss, this is called the EPD-20 upgraded version of the engine."
"It actually has a military thrust of 33 tons and a maximum thrust of 48 tons??"
"And it's a three-dimensional vector engine? The supersonic cruising speed exceeds Mach 2.5? The top speed exceeds Mach 3.2?"
"Ten minutes at full thrust?"
"Is this definitely for our J-20?"
The two of them gasped almost at the same time, so terrifying! !
Every data can shock both of them!
If it weren't for the complete authenticity of the document, both of them would have suspected it was a prank!
However.
Not only the two of them had this reaction!
All the senior air force officials were stunned when they looked at the data displayed above!
Good guy, do you call this thing the J-20? Is this confusing the space shuttle with the aviation aircraft?
Does this thing burn kerosene or chemical fuel? This is the performance that an aircraft engine can achieve! ?
With a lot of questions in their heads, major air force bases shipped J-20s to Yanjing in batches.
Waiting for the installation upgrade!
"Even if it only has half the performance, this J-20 is enough to become the most powerful fifth-generation aircraft!"
This sentence rings in everyone's heart!
There is no extravagant expectation that it can reach this outrageous level. Even if it is only half the performance, that is enough!
Time flies by.
A few days later.
In the Jiaxing company, Yang Mi is starting a live broadcast! !
Suddenly, a call came in.
"Sister Mi, come over to my house!"
"I have good news for you!!"
this!
It's the voice that tens of millions of viewers have been waiting for!
PS: Please recommend monthly tickets, there are still tickets available at night, please hurry up!
