Chapter 443: Turboshaft engine

<>
Immediately start research on turboshaft engines. Mobile terminal
Mainly refer to the model of the Black Hawk helicopter and appropriately increase the performance parameters.
It is equipped with General Electric's T700 turboshaft engine, with a single output power and 1560 shaft horsepower.
Turboshaft engines are a bit different from turbojet engines. The process loss of power transmission is large.
After all, turboshaft engines are not jets, but drive blades to rotate.
The output power, but the actual application may be less than 75%. It is also less than three-quarters.
Each Black Hawk helicopter is equipped with two T700 engines. The total power is 3120 shaft horsepower.
So, what model does Wang Bu'an plan to develop?
How much power is prepared?
He plans to use a single turboshaft engine.
Each helicopter is equipped with only one turboshaft engine to reduce costs. However, sufficient power must be guaranteed.
In other words, the power of a single unit needs to be more than 3000 axle horsepower.
The engine power of the Chinook transport helicopter is about 4800 axle horsepower.
Obviously, this motivation is not enough.
How can Transformers' technology be equal to the other party?
It needs to be at least twice that of the other party.
If it is doubled, it is 6000 axle horsepower.
I feel that this motivation is still a bit small.
After all, this is technology from the planet Cybertron! If you don't make good use of it, you are sorry for yourself and for all the people on earth.
Do the best.
Tyrannosaurus rex must have the style of Tyrannosaurus.
One word is: big.
The two words are: very big.
The three words are: very big.
What are ten words? Big big, big big, big big!
Just one step...
Direct 10,000 shaft horsepower.
That's left and right.
It is also about the same power as a Rock 500 marine engine.
However, this power is still not the maximum.
Polar Bear’s Mi-26 helicopter is equipped with a D-136 turboshaft engine with a single power. Wang Bu'an designed it to be bigger.
The Mi-26 is the largest helicopter in the world. It is also the largest helicopter in the world.
It is equipped with two D-136 turboshaft engines. Total power.
The fuel consumption per hour is about 3000 liters (2.5 tons)...
Calculating other expenses, the cost of one-hour flight is as high as 130,000 yuan.
Such costs are not affordable for ordinary people. Especially if it is used frequently. Big countries and powerful countries are unbearable.
The fuel cost alone is a very scary figure.
We can't give it to people anymore.
The performance parameters of Tyrannosaurus rex industry must be the highest.
What we are after is not the most suitable.
What we are after is the greatest.
Continue to increase the parameters.
Increase the power output of the turboshaft engine to below. It is also 13,600 axle horsepower.
Theoretically, the engine with 13,600 shaft horsepower is enough to push the Black Hawk helicopter to an altitude of 15,000 meters.
That's right, 15 kilometers!
It's almost flush with the fighter.
What is this concept?
The tallest Mount Everest? It is also 8848 meters.
In other words, it is possible to fly over Mount Everest easily. Not panting at all.
Of course, its speed is absolutely incomparable with fighter jets.
The speed of a helicopter generally does not exceed 400 kilometers per hour. It is also 100 meters per second.
If it exceeds this number, flying will become very dangerous.
After all, it is a rotary wing flight, not a fixed wing.
The maximum flying speed of Mi-26 is 295 kilometers per hour.
The maximum flying speed of the Black Hawk helicopter is 357 kilometers per hour.
The maximum speed of the Chinook transport helicopter is 315 kilometers per hour.
Wang Bu'an's requirements are not high.
350 kilometers per hour is enough.
Too fast is not good. Affect safety.
If one is not enough, equip two. The total power of the two sets is 20,000 KW, which is almost a ship.
"Wang Bu'an, what are you muttering?"
"what?"
"I ask you, what are you whispering?"
"It's okay."
Wang Bu'an shook his head.
What do you know about the things I want to mutter?
You are an auctioneer. How much do you know about this kind of technical stuff? Do you know what a wing load is?
"Bad intentions."
"Ok?"
"I said I must be thinking about doing bad things."
"No."
Wang Bu'an looked around quietly.
He moved quickly close to Liang Jingshu, pressed her ears, and deliberately stopped talking.
"What are you doing?" Liang Jingshu suddenly became alert.
"I'll tell you a secret." Wang Bu'an said.
"what?"
"I have a single tens of billions of business, do you want to participate?"
"rogue!"
"Don't be crooked. That's a business of one or two billion. Who can shoot tens of billions at a time? I'm talking about serious business."
"rogue!"
Liang Jingshu's cheeks flushed.
By accident, she was taken into the ditch by Wang Bu'an.
She thought Wang Bu'an was talking about pornography. She dismissed the other party without thinking. Also ready to slap each other.
Unexpectedly, what he said was actually business?
wrong!
How could it be business?
He must be fooling himself! Are you kidding a business of tens of billions?
It was her uncle Xiong Haishan, and there was no one-time business of tens of billions!
There is no net worth of tens of billions.
What's more, it is a business of tens of billions?
In this world, how many people are qualified to conduct tens of billions of business?
Unless it is the few people whose surname is Ma.
Is Wang Buyan's surname Ma?
It's not.
His surname is Wang.
The king of the old king next door.
Others surnamed Wang may not be good people. But this Wang Bu'an is definitely not a good person.
While in Yucheng, she heard of some messy relationships.
He seems to be the little white face raised by Lu Lingqi?
Anyway, the rumors outside said so.
Now it seems to have some credibility.
He looked like a standard little white face. Sisi's, weak, and charming.
"Nonsense."
"I'm serious."
"Okay. Then tell me, what business are you going to do?"
"Helicopter, understand?"
"understand."
"The power system of the helicopter, understand?"
"..."
Liang Jingshu wanted to understand.
But in the end it still didn't say anything. no way. She really doesn't understand.
How could she understand the power system of a helicopter? One listen is mechanical knowledge. There seems to be a little tall taste?
"what are you going to do?"
"You said, if I sell 5 million sets. If someone else wants to buy 10,000 sets, how much is the total price?"
"Are you daydreaming?"
"No."
"50 billion? You're mad."
"Haha. I'm serious. Do you want to participate? I will give you a little bit between my fingers."
"You must be scamming!"
"I want to support you because you look a bit handsome."
"Thank you. No."
"Hey."
Wang Bu'an shook his head.
The dog bites Lu Dongbin and doesn't know good people.
Originally wanted to give you thousands of millions of pocket money, but you actually didn't do it? There is no way.
I can't force money into your pocket?
Our relationship has not yet become so close...
However, it is tens of billions again!
How to spend so much money?
Suddenly feel that you have become the protagonist of Shenhaoliu's novel? The sky falls into the trap!
So much money, I don’t know how to spend it.
Send beautiful women, beautiful women don't want it.
Is it thrown into the sea?
What a headache.
Forget it, continue to ponder technical issues.
The weight of a turboshaft engine should not exceed 1 ton in principle.
It must be produced in its own industrial park. Otherwise, the quality cannot be guaranteed. He will never allow quality problems.
Again, you can doubt my character. But I must not doubt my product.
But in this way, the number of robot elves is not enough.
It's time to buy the robot wizard again.
Oops, poor faith value.
It feels that every point of faith has been blackmailed by Transformers.
But no way.
The robot elves are still needed.
Buy buy buy.
Buy thirty.
As a result, hundreds of millions of belief values ​​are gone.
What he wants most now is to sell Liang Jingshu, and then exchange for 10 billion belief value.
Weird, why sell Liang Jingshu? What is her relationship with you?
do not mind the details……
After determining the performance parameters, each component is subdivided.
Relatively speaking, the turboshaft engine needs a lot of supporting parts. There are more turbojet engines and turbofan engines.
The quality requirements of various parts are also very high. Especially the bearing capacity of the hinge.
Each part must be processed by yourself.
Wang Buyan is not at ease if it is handed over to others for processing.
First, the turboshaft engine.
Secondly, the blade.
Again, it is the hinge.
Again, the braking system.
Ordinary fighter jets do not have a braking system.
But the helicopter does. When necessary, the rotor can quickly reduce the speed.
complex.
It is indeed more complicated.
If the parts are dug out one by one, the power system alone can fill the size of a basketball court.
For helicopters, the power system is almost the most important part. Almost accounted for more than 60% of the cost. Including the rotor, it can be included in the scope of the power system.
Obviously, it is impossible for Wang Bu'an to simply study engines. The entire power system must be developed together.
Otherwise, there is only the engine, without matching rotors and hinges, which is useless.
In fact, this is basically the study of a helicopter.
Because, as long as the power system is fixed, the other parts are stacked.
The benefits of sufficient power are:
First ~EbookFREE.me~ the load capacity is naturally enough.
Second, the speed is naturally improved.
Third, the voyage is naturally no problem.
Fourth, the ceiling will be very amazing.
The biggest defect of the current domestic helicopters is the power system. It is also the heart.
The imported Black Hawk helicopter is there. You can remove it as you like. Feel free to research. Reverse development as you like. However, more than 20 years have passed, and there has been no reverse development!
This fully shows that the power system involves many aspects. Fully applicable to the barrel theory.
As long as there is a short board, the product cannot be made.
