192. The Aviation World Was Shocked, Longguo Engine Won In A Crushing Manner
The first ground test of the aircraft engine begins.
Engine thrust test.
This is also the most important one.
After all, if the thrust of an aeroengine is not enough, then no matter how good the other parameters are, it will be useless.
There is a saying among military fans, it is called flying bricks with great strength.
That is to say, the engine thrust is large enough, and the sunblock can fly even if it turns around.
You can do whatever you want with the aircraft shape, aerodynamic design, etc.
Yingjiang's fighter jets all use conventional layouts and rarely use special aerodynamic layouts such as canards and delta wings.
Whether it is the previous generation F15, F16, or the later F22 and F35, they are all conventional layouts.
The reason is because Yingjiang's aero engine is so powerful that there is no need to spend time on aerodynamic layout and flight control.
Simply using the most traditional conventional layout can achieve very impressive performance.
The J20 of Longguo uses canards and an extremely complex flight control system because Longguo's aeroengine thrust is relatively small.
We can only use all the wisdom of aircraft designers to make up for the problem of insufficient engine thrust through aerodynamic layout and flight control systems.
The first is GE's product. What they came up with is the CF56-600, a very mature engine.
The engine started and the turbofan began to spin rapidly.
The rotation of the fan drives the air into the combustion chamber and mixes with the fuel for combustion.
The high-temperature, high-pressure and high-speed airflow after combustion will be directly sucked away by the rotation of the high-pressure turbine blades. Then it continues to flow to the low-pressure turbine blades, and finally enters the afterburner for combustion again, and is finally ejected from the tail nozzle!
Huge air currents carrying billowing heat waves
All personnel at the scene were at least fifteen meters away from the engine, but the air wave still made people almost unsteady.
In everyone's ears, there was only the sound of roaring.
After a few minutes, the engine slowly shut down.
On-site staff used sensors and airflow monitoring equipment to calculate the engine's thrust.
"GE Company, CF56-600 engine, thrust 15.41 tons!"
There was a burst of warm applause. 14
This thrust data is already very good and has reached the world's advanced level.
In comparison, the thrust of the LEAP-C engine currently used by the Longguo aircraft L919 is only 13.8 tons.
In other words, in terms of thrust alone, GE's CF56-600 far exceeds the engine currently used by L919!
Next, is the PW1000G engine of Puhui Company.
After the same operation process,
"Puhui Company's PW1000G engine has a thrust of 13.2 tons!"
There was polite applause at the scene. This thrust was not even comparable to the engine currently used by L919.
Puhui's executives didn't pay much attention to this result.
After all, their bid this time was not based on performance, but mainly on price advantage.
Then, there is the star product of this bidding, CHM's LEAR-CA engine.
It is also the most promising product in the aviation industry around the world.
The LEAP-C engine currently used by Longguo Aircraft L919 aircraft is also from CFM.
It's just that they played a trick on Long Guo Shangfei at that time.
Knowing that Longguo Commercial Aircraft did not have many choices, the LEAP-C engine provided to Longguo Commercial Aircraft not only had the highest price, but also had the worst performance, which was far inferior to the products they provided to Boeing and Airbus.
Their arrogant attitude is also one of the reasons why Longguo Commercial Aircraft launched the tender for new aero engines this time.
CFM is a little more serious this time and has come up with the latest improved engine.
It seems that they are paying more attention to Longguo Commercial Aircraft.
But the attitude expressed in it is also extremely arrogant.
You are not satisfied with our previous products and want to invite bids for new engines.
Then let's be a little more serious and win your new engine bid.
No matter how dissatisfied you are, you still have to use our products.
There is quite a feeling that your monkey grandson cannot escape from the palm of my Tathagata Buddha's hand.
"CFM's LEAP-AC engine, thrust 15.88 tons!"
hiss......
There was a burst of warm applause.
The LEAP series engines are indeed the best engines for current narrow-body passenger aircraft.
This data is simply great, far exceeding all competitors.
The executives of CFM also looked proud.
The look he looked at Song Wenhao was also full of arrogance and provocation.
How about it?
Are you dissatisfied with our previous products and want to change to another engine supplier?
Did you see the result?
Our CFM company's products are still the best.
You have no choice but to use our products.
The last one tested was the Yangtze No. 1 engine of Longguo Aviation 501 Research Institute.
All the media at the scene focused their lenses on this aeroengine, which seemed to be smaller than other engines.
"Why does this engine look so small?"
"Maybe it was modified with a military aircraft engine. It has inherent deficiencies, so the size is smaller."
"Indeed, this Aviation 501 Research Institute has never developed a civil aviation engine. It must be much different in all aspects.
"If Longguo Commercial Aircraft Corporation did not favor the Aviation 501 Research Institute, they would never win."
"How can it be partial? Authoritative organizations in the aviation field from all over the world are here. Even if Longguo Commercial Aircraft Corporation wants to win the Aviation 501 Research Institute, it can't do it. We can only look at the real performance.
Everyone at the scene was whispering and discussing this aero engine from the Aviation 501 Research Institute.
Fang Yingrui took a deep breath, and he was also a little nervous at this time.
He said to Han Yue: "Han Yue, you are the chief designer of this engine, start it.
Han Yue nodded.
The engine start button was pressed lightly.
The 16 fan blades of Yangtze River 1 began to rotate slowly, faster and faster!
Each blade has extremely complex curves and radians, which draw air into the engine combustion chamber with great suction.
"Hey... the engine from the Aviation 501 Research Institute is so quiet. It is obviously much lower than other aero engines!" a reporter said in surprise.
"Yes, when I tested several previous engines, my ears were so shocked that I could hardly hear other sounds. But now I can easily hear your voice."
"Did Longguo's aircraft engine malfunction and not start at all? Otherwise, how could the sound be so low?"
Everyone at the scene was very surprised.
They are all professionals in the aviation industry and are very familiar with the noise of aircraft engines.
They have never seen any aircraft engine so quiet after starting.
Isn’t this an aircraft engine?
Windmills are louder than this!
Even the staff responsible for testing were confused.
They looked at the location of the personnel of Aviation 501 with doubtful eyes.
What happened to your engine?
Is there a malfunction?
Is it not started?
The executives of CFM, Rolls-Royce, and General GE raised the corners of their mouths and almost couldn't help laughing.
Longguo wants to use civil aviation engines, but is it still early?
This was the first test, and something went wrong. Which airline would dare to use this kind of engine?
As a result, everyone at the scene turned their attention to Fang Yingrui and Han Yue.
I want to see what their expressions are like.
Angry or anxious?
Will they ask Longguo Commercial Aircraft Company to give them another chance to test?
All this happened in just one minute.
Just when everyone wanted to see something on the faces of Han Yue and Fang Yingrui.
Boom... Huh... Huh...
A huge flow of air roared out from the nozzle of the engine with overwhelming momentum.
It carried huge heat and energy, almost overturning a vehicle more than thirty meters away.
Showing such surging power, the Yangtze River No. 1 engine still runs very quietly.
Everyone could hear only the sound of air rushing past.
The sound of the engine running seemed to be masked by the sound of airflow.
The eyes of everyone present were filled with shock!
Obviously, the engine of the Aviation 501 Research Institute did not malfunction and started normally!
It takes several minutes for an aircraft engine to start and eject hot airflow to generate thrust.
They just didn't hear the sound of the engine running, so they thought something was wrong and ignored it.
But now, this engine has sprayed out hot airflow and generated huge thrust.
It is still so quiet, which only proves that... this engine is indeed unique in terms of noise control.
At this time, someone else discovered that the Yangtze River No. 1 engine was extremely stable and produced almost no vibration when running.
Compared with other engines, it is as if it is not affected by any airflow at all.
The stability of engine operation is also very important for aviation safety and can improve the maneuverability of the aircraft. Reduce wing metal fatigue and increase the life of the aircraft body.
Many aero-engine manufacturers are doing their best to improve engine stability. But I've never seen an engine run so smoothly.
After a brief moment of disbelief and shock.
Technicians finally measured the thrust of the Yangtze River No. 1 engine.
"Aviation 501 Research Institute, Yangtze River No. 1 engine, thrust... 29.8 tons!
The technicians could hardly believe the numbers in front of them.
29.8 tons!
This is nearly twice that of the LEAP-CA engine!
Is this still the engine of a narrow-aisle airliner?
This is simply the performance of a dual-channel large aircraft engine!
With a smaller size than the LEAP-C engine, it achieves nearly twice the thrust of the LEAP-C.
Even compared with the GE9X engine with the highest thrust on Blue Star, the thrust is more than one-third of that of GE9X!
The size is less than one-fifth of the GE9X, but the thrust is more than one-third of the GE9X.
This shows that the thrust-to-weight ratio of this engine will be twice that of GE9X!
Three times that of LEAP-CA!
This is simply a miraculous data!
"Impossible! This is absolutely impossible! There can be no narrow-body passenger aircraft engine in the world that exceeds the LEAP-CA077!" CFM executives murmured.
"We doubt the results and request a retest!" a Rolls-Royce representative declared.
Song Wenhao looked at Han Yue and Fang Yingrui with questioning eyes.
After all, Longguo Commercial Aircraft Co., Ltd. has made its processes so that everyone can
No one can find fault with it, and they can only accept the protests and suspicions of these foreign companies.
Han Yue nodded.
If you want to take the test again, then take the test. ,
Anyway, our engine is here, and its strength is absolutely crushing.
The scene was quiet,
Yangtze River No. 1 engine is running again.
Still so stable, so quiet,
The technician reads the parameters again,
"Aviation 501 Research Institute, Yangtze No. 1 engine, thrust...thrust...29.8 tons!"
The scene remained quiet.
Everyone was shocked.
The eyes looking at Han Yue and Fang Yingrui were full of shock.
They are all professionals in the aviation industry.
They know what this means.
It means that Longguo has finally created an unparalleled civil aviation engine. With a crushing advantage, it defeated its competitors.
This means that Dragon Kingdom’s aircraft will no longer have heart disease problems.
This means that Longguo's aviation industry will no longer be manipulated by large foreign companies.
It even means that the Dragon Kingdom's air force will achieve new development and leaps.
Executives at CFM, Rolls-Royce, and GE began to panic.
If this engine from Longguo is really that good.
So it's not just that they can no longer get orders from Dragon Kingdom.
And their existing orders will also be taken away!
What airline wouldn’t want to use such a good engine?
The two aircraft manufacturers, Boeing and Airbus, will also be tempted to use this engine, right?
Today, the relationship between strength and weakness has been completely reversed.
At this time, Song Wenhao continued: "Our bidding continues. Next is the ground test. It's time to test the engine noise and fuel consumption."
Although he had tried his best to restrain himself, there was still joy that was difficult to hide in his voice.
Everyone at the scene looked speechless.
We are not deaf.
We all heard the sound of Yangtze River No. 1 operating just now.
We almost thought that the engine was not running except for malfunction.
We have never seen such a quiet aircraft engine in our entire life!
More than noise?
How to compare?
This engine is quieter than my air conditioner!
