Pangu Aircraft Test Run
Aircraft engines are very valuable.
Take a Boeing 737-800 as an example.
The unit price is US$90 million.
The engine cost accounts for half of this.
About $40 million.
And when the aircraft is scrapped.
The whole machine can be purchased for RMB 10,000, and the engine will cost at least RMB 8,000 to disassemble.
In the next five years, Shan will be in China.
The aviation engine market size exceeds 110 billion yuan.
Among them, more than 80 billion yuan is for the civilian market and more than 30 billion yuan is for the military market.
The entire market size of Blue Star will be as high as one trillion yuan.
Such high-tech and high-value products.
Su Chen must figure it out.
He didn’t do it for the money.
I just like the feeling of beating up foreign countries and squeezing their necks.
these years.
Waiguoren implemented a blockade on aircraft engines.
All relevant academic conferences, research and development materials, technical details…
are all kept strictly confidential.
This led to China’s backwardness.
But now with Su Chen, everything has changed.
【Ding! Congratulations to the host for obtaining the core machine technology and drawings]
[Ding! Congratulations to the host for winning 20 aviation experts]
[Ding! Congratulations to the host for getting 300 senior engineers]
[Ding! The host’s remaining points are now 18,350,888,888]
plus the talents purchased when building rockets.
Now in aviation.
Su Chen has 25 experts and 500 senior engineers.
As the leader, Mr. Lu respectfully led the team to wait for instructions.
“Make a large bypass ratio turbofan engine.”
Su Chen said, “One that can be used as a core machine.”
There are many types of aviation engines.
In the early days, it was a piston engine, which was characterized by high power and fuel efficiency.
But the power-to-weight ratio is too small, the thrust is not strong enough, and it cannot fly fast.
Therefore it is used very little.
The other four common ones are:
turbojet, turbofan, vortex, and turboshaft.
This vortex refers to
the common feature of engines such as turbines, which are composed of three main components.
Compressor, combustion chamber, turbine.
The three of them together are called the core machine.
You can tell just by the name.
The core engine is an engine that can be expanded into many series.
Mr. Lu nodded: “Okay, we promise to complete it within four months.”
Su Chen discussed it in detail with the team.
The engine model is confirmed to be SC-1 engine.
The thrust is between 9 and 13.5 tons, and the bypass ratio is about 8.5 to 11.
The maximum cruising speed fuel consumption does not exceed 0.5 tons.
This is the most widely used regional jet engine.
After confirming.
The R&D center at Huazhi headquarters started to get busy.
Building a turbojet engine is no simple matter.
Intakes, low-pressure turbines, high-pressure turbines, combustion chambers, afterburners, nozzles…
Some of these components can be purchased, while others can only be produced in-house.
Fortunately, Su Chen now has his own machine tool.
Capable of precision machining.
High temperature resistant materials are used in engine blades, bearings, etc.
It directly lifts the aero engine to another height.
to the final result.
Su Chen was very confident.
So Liu Jiadao was arranged: “Sign up for the international air show at the end of the year.”
This is an air show held in a beautiful country.
Su Chen just wanted to slap GM and Pu Hui in the face at their doorstep.
Traveling day and night, three months passed quickly.
During this period.
Huazhi’s commercial rocket launch business has strong momentum.
Because of the recyclable technology, the cost is reduced by 40%.
It now averages two launches per month.
Musk is working particularly hard. He is working hard to achieve a twice-weekly launch frequency
compared to BYD and Tesla electric vehicles, and has completely occupied 90% of the Chinese market.
Xiaoyao CPU and Hongmeng operating system have completely replaced Intel and Weiruan.
Chips, photolithography machines, automobiles, steel and other businesses are in full bloom.
It is under this thriving trend.
Su Chen received good news from Pangu Engine.
He finished his last bite of oats and wiped his mouth lightly.
Then he said: “Baoqiang, send me to the test center.”
*****
Boom~~~
He hasn’t arrived at the scene yet.
Su Chen heard an ear-splitting roar.
It was busy on and off the field at the moment.
“Mr. Su, the engine production has been completed.”
Mr. Lu was wearing a blue uniform with an excited expression on his face.
Look at the huge engine in the test control center.
Su Chen’s heart also surged with immense expectations.
This high-tech R&D thrill.
Probably the most extreme fun in the world.
Nothing can compare.
Su Chen nodded and said: “Let’s start!”
as the button started.
The engine instantly sprayed out blue tail flames several meters long.
Wow~~~
The surrounding engineers and workers all applauded.
The smiles on their faces could not be suppressed at all.
Mr. Lu watched the parameters on the LCD screen closely throughout the whole process.
“Report, the engine combustion chamber is working normally!”
“Report, the n1 fan is operating normally, and the thrust parameter requirements are met!” ” Report
, the EPR engine pressure ratio meets the
requirements!” “Report, the oil circuit is operating normally, and the fuel consumption rate meets the requirements!”
… …
Listen to the test results one by one.
The corners of Su Chen’s mouth raised, revealing a happy smile.
Soon the one hour test was over.
Of course, engine testing is far from truly over.
For civilian aircraft without parachutes.
Safety is always the most important criterion.
Therefore, Su Chen required that the test run time should exceed 2,000 hours.
Water swallowing test, hail test, bird sucking test, blade throwing test, etc.
All must be carried out without fail.
So it took nearly three months.
Pangu Civil Aviation Engine has finally completed the most important test phase.
Below is the official joint inspection of China.
According to the time told by Su Chen.
This time, dozens of people came to the review team.
Through the introduction, Su Chen learned.
They are mainly divided into three groups:
1. Minister Yang represents the leadership.
2. President Han of the Chinese Academy of Sciences, Duan Gong, chief engineer of the large aircraft project, and a ten-person aviation expert team.
3. Leaders of the Military Strategy Bureau who shouldered different battles and stars, a total of three.
Unexpectedly, this test drive actually alerted the military personnel.
Although Su Chen was a little surprised, his face remained calm.
Stand behind specially made glass.
Everyone’s faces were filled with excitement.
They are eager to see the data and test results.
Everyone hopes that this SC-1 engine can pass the review and be mass-produced.
This is also very important to China Airlines.
The aviation engine is called the heart of the aircraft.
Its performance determines the quality of an aircraft.
The aircraft engine failed.
Other avionics and flight control technologies are meaningless no matter how advanced they are!
Think of this.
Minister Yang took a deep breath and calmed down.
He nodded to Su Chen with satisfaction.
Su Chen understood and said to the staff:
“Get ready to enter the test driving state, countdown to 10 seconds.”
