Chapter 165: All Canada

Wang Buyan is generous.
The raw materials for manufacturing turbofan 6 engines are all very high-grade.
Either a tertiary titanium alloy.
Either it is a tertiary high temperature corrosion resistant alloy.
Even the small ceramic insulation layer, or rubber seal ring, is above grade three.
If you want to do it, do the best.
This is Wang Buyan's innate obsessive-compulsive disorder.
The so-so tinkering out of a turbofan 6 is definitely not his style. It’s better not to do it if it’s not done.
The temperature tolerance of all raw materials is over 7,200 degrees.
What is a small 1400 degree?
7000 rpm...
0 turn...
This is the limit of turbofan 6 design.
It is also the most violent and toughest time. At this moment, the power it bursts out is the strongest. Unless it is to open the afterburner.
Even if it is 100 meters away, the strong jet of air from the tail can be felt.
No one can stand up to 150 meters away.
At a distance of two hundred meters, living people may be burned by the temperature of the airflow.
However, there is no thrust reading yet.
The thrust test system is not connected at all.
Chen Daguang feels unnecessary.
You pass the most brutal test first.
He decided to change the order of tests.
He wants to teach Wang Bu'an a little lesson.
Otherwise, this little guy's tail would almost be lifted out of the sky.
"Prepare for afterburner test."
"Ok."
Others move their mouths, and Zhao Ce and others are going to break their legs. They need to make more preparations.
The turbine has the highest speed, not afterburner.
What is afterburner?
It is to inject fuel into the airflow from the engine. Due to the high temperature of the airflow, the fuel burns instantly and expands extremely to generate extra thrust.
Generally speaking, the higher the temperature in front of the turbine of a jet engine, the greater the thrust of the engine. However, due to the working environment of the turbine, it has to withstand both extremely high temperatures and huge thrust. Therefore, due to the material of the turbine In general, the temperature before the turbine can only reach about 1650k. However, this still cannot meet the thrust requirements of military engines, so an afterburner is added behind the turbine to reburn to increase thrust. There are no rotating parts in the afterburner, so the temperature can reach about 2000k, which can increase the engine thrust by more than 150% in an instant.
Because the gas it uses is exhaust gas after combustion in the combustion chamber, the oxygen content has been reduced, so the efficiency of the afterburner is not high, and the fuel consumption is huge. Most of the fuel carried by the aircraft will only be enough for the afterburner. Use it for a few minutes. Therefore, the afterburner is generally only used for a short time when the highest thrust is required, such as taking off on an aircraft carrier, breaking the sound barrier for supersonic flight, or using fighter jets in situations such as fighting. (Refer to the fragment of missile attack in the movie "Deep Behind Enemy Lines")
The original MiG-25 fighter jet relied on the afterburner to easily break through Mach 3, so that the missiles of a certain country could not catch up. It shocked the Western world, thinking that the Soviets had invented some aerial artifacts, which caused the Western world to be destroyed The shadow of Grid-25 has been over for ten years. However, the engine life of the MiG-25 was over after the afterburner was turned on. Replace the engine when it hits the ground.
Due to the low fuel efficiency, few civilian aircraft use afterburners. The only civil aircraft using afterburners are the Concorde and the Tu-1 supersonic passenger aircraft, which have already been eliminated. For the time being, the supersonic flight of a civil airliner can only be a dream.
The brutal test is 10 minutes of full afterburner.
The more brutal test is 20 minutes of full afterburner.
The most brutal test is 30 minutes of full afterburner.
Basically, after the test, the engine is finished. All parts must be scrapped.
"How long is it set?" Zhao Ce asked in a low voice.
"30 minutes." Chen Daguang said blankly.
Cheng Kailong frowned.
This is obviously to give Wang Bu'an a smashing power.
Coming up is the most brutal test of 30 minutes. Can the newly-baked turbofan 6 bear it?
Other engines are built step by step.
Try it for 10 minutes first.
After the test, find the damaged parts.
Repeated tests and repeated searches for damaged parts. Then targeted strengthening.
After the quality of the parts has been improved, and with a certain degree of certainty, the 20-minute test will be tried.
Basically, being able to pass the brutal 10-minute test shows that the engine has a good potential.
It is impossible for a general fighter to be fully afterburned for more than 10 minutes.
Even if the engine can stand it, the fuel consumption can't stand it.
Fighters like the f-15e can only carry 6 tons of fuel.
If it is in a full afterburner state, it is estimated that it will run out in less than 5 minutes. Even a country like the US can't afford it.
The MiG-31 is the fastest main fighter in the world today, with a maximum speed of Mach 2.85 and capable of carrying 16 tons of fuel. If it is to enter the full afterburner state, it is estimated that it will only persist for 10 minutes. It can be seen that the fuel consumption of the engine can be said to be very scary in the case of full afterburner.
You know, that is basically direct injection!
Spray a large amount of oil directly into the hot air stream.
Spray as much as you can.
Spray as fast as you can.
The 30-minute full afterburner test is basically for scrapping the engine.
Anyway, the previous tests are almost scrapped, and I don’t care if they are scrapped the last time.
At this stage, Sun Chaosheng is the most nervous.
The 771 Research Institute under his leadership specializes in high-temperature corrosion-resistant alloys.
Before, he had received part of the high-temperature corrosion-resistant alloy. Tests have proved that the performance of these high-temperature corrosion-resistant alloys is indeed very good. It can withstand high temperatures above 3000 degrees. However, due to procedural issues, it has not yet been applied to the manufacture of aero engines.
In the end, Wang Bu'an actually took the lead.
There is no doubt that the turbofan 6 in front of you is definitely made of a new type of high-temperature corrosion-resistant alloy. The temperature tolerance is very high.
Sun Chaosheng can basically conclude that the 10-minute brutal test is no problem.
According to theoretical calculation, the temperature of the afterburner is about 2000 degrees.
However, theory is theory, reality is reality...
Everything depends on the test data.
If this time the Turbofan 6 successfully passed the test, he would be able to let go of his hands and feet.
What Taihang, what Kunlun, and all domestically-made aero engines will use the new high-temperature corrosion-resistant alloy provided by Wang Bu'an on a large scale.
"Comrade Xiao Wang." Sun Chaosheng took the opportunity to greet Wang Bu'an quietly.
"Professor Sun. Hello." Wang Bu'an responded politely.
"Are you sure?"
"Have."
"How much is it?"
"One hundred percent."
"it is good."
Sun Chaosheng nodded in satisfaction.
This is the answer he most wants. Hope the final result is the same.
In fact, Sun Chaosheng also suffered a certain amount of pressure. He also wants to promote high-temperature corrosion-resistant alloys. The problem is that these high-temperature corrosion-resistant alloys are all three-no products.
Including himself, there is no way to fully prove that those high temperature and corrosion resistant alloys can be smoothly used on aero engines. After all, an aero engine costs millions of dollars. If there is not enough theoretical verification, there is not enough test data, it is impossible to try easily. The procedures must be followed in accordance with the regulations.
Only a guy like Wang Bu'an who was a monk halfway through, who didn't follow his routine at all, could mess around.
The test of turbofan 6 is undoubtedly a major test of new raw materials.
All raw materials from Tyrannosaurus Rex industry will have the opportunity to show their faces.
If the test is successful, Tyrannosaurus Rex Industry will become famous in one fell swoop.
If the experiment fails, then...
"It's been two months, but it hasn't been applied in practice yet?" Wang Bu'an asked Cheng Kailong in a low voice.
"Do you think you can use it if you want? What if you use it wrong?" Cheng Kailong said solemnly, "Of course there are strict regulations. It must be fully verified to ensure nothing is wrong."
Wang Bu shook his head slowly.
Cheng Kailong is right. Seek stability. Must be stable.
Can't make mistakes easily.
All research institutes have this attitude.
It cannot be said that this idea is wrong. But, isn't it true that all day long said that the time left for us is running out?
If I knew it, I got a few big guys out in advance.
Fortunately, it's not too late this time...
The turbofan 6 must be fired. It must also be loud. Let relevant seniors know.
He deliberately glanced at Miao Yongfeng.
Miao Yongfeng also gave him a look of hatred. Show no weakness.
Wang Bu'an squinted at each other, with the corners of his mouth tilted up at a 45-degree angle, and said meaningfully, "Professor Miao, what do you think of your eyesight?"
"Of course my eyesight is better than you." Miao Yongfeng said with a bored look, "what are you doing with all this nonsense?"
"Since you have a good vision. Then you say, this turbofan 6 can last for a few minutes?"
"Five minutes at most!"
"Are you sure?"
"of course!"
"What if it takes more than five minutes? Will you poking your eyes?"
"you!"
Miao Yongfeng was immediately forced to the corner.
Others were also secretly surprised. Wang Bu'an is a grudge! This is a fight!
Just because Miao Yongfeng had a conflict with him, he always targeted Miao Yongfeng. Now he has not forgotten to provoke Miao Yongfeng. There is no one to hold grudges like this.
In the future, if anyone says that Wang Buyan is a person who bears no grudges, they will definitely spit on each other's face.
Sure enough, "Never bear grudges" Wang Bu'an!
"Professor Miao~EbookFREE.me~ Let's make a bet." Wang Bu said slowly.
"We are all scientific researchers, and we don't have these low-level tastes." Miao Yongfeng replied coldly, "You better improve your recuperation."
"If the turbofan 6 can last for five minutes. You poke your eyes. If you can't, I poke your eyes."
"Naughty!"
"Wang Bu'an, don't mess around!"
"Wang Bu'an, this is not a place for children to play home!"
The old professors are all angry.
This Wang Bu'an really didn't know that the sky was so great.
Still poking his eyes?
Do you want to be so insidious?
