Chapter 669: Cheating again (below)

"First solve the problem of materials."
Guo Tailai will not conceal the teacher: "I let the company study from other directions, first solve the urgently needed material problems."
"and then?"
The sister continued to ask, she did not doubt that when Guo Tailai was willing to let the company set up research on certain materials, these materials will be studied in a short period of time.
"Then I just want to improve the power of this turboshaft engine and reduce fuel consumption."
Guo Tailai said very ordinaryly, it seems that this turboshaft engine has been researched by General Dynamics for decades. In his hand, as long as the material is solved, it is easy to improve these indicators.

How much can you improve?

Zhao Wei asked excitedly.
When others hear it, I am afraid that Guo Tailai will make a big statement, but the sister is convinced of her own fat man.
If Guo Tai can improve, it will definitely improve. She is only curious about how much she can improve.
"In theory, if the material is right, the power can be increased by 50%."
Guo Tailai thought for a long time and said: "The fuel consumption is reduced by 25% and the weight is reduced by 20%. Well, it's almost like this."
Guo Tailai apparently felt that when the sisters heard the data, the hand that touched Guo Tailai’s cheek became stiffer.
Hey, a small amount of data can surprise the sister-in-law. Guo Tailai’s heart immediately gave off a smug laughter, and reached out and put the little sister’s slightly stiff hand in his hand.
The sister is not good at this, knows too much, and can't scare her easily when she meets face to face. It is rare to have a chance to surprise the sister.
"Think about it, the sister, such an engine, the performance of the plateau is even stronger than the original t700 series."
Guo Tailai proudly rushed to the sister-in-law: "Even if it is exactly the same copy of the Black Hawk, the helicopter's voyage or load capacity can be improved a lot."
"Fat!"
The sister's hand has softened, but I am very worried. Guo Tailai asked: "You want to improve the voyage and load capacity of the helicopter this time, are you preparing for the war?"
"No."
Guo Tailai put the teacher's hand on his cheek again and smiled and shook his head: "Our country is big enough, but our air transportation capacity is too bad, and the capacity at some key moments is not enough.
We need a black-eagle-like helicopter that can be used across the country, whether it is patrolling or fast maneuvering, or for disaster relief, which requires a large number of helicopters.
Even if there are some serious illnesses, I am afraid that it is more convenient for the aircraft to be sent across the city than the ambulance.
If you are in Beijing, I am afraid that you have to be blocked on the way to the hospital to doubt life.

"I am very curious, fat."
The sister did not doubt the purpose of Guo Tailai. During this time, he has been urging the domestic research and development of helicopters. He has asked once this time, this time a similar answer.
The curiosity of the sister is how Guo Tailai can achieve this: "How do you do this?
Americans have studied engines for decades. Even if you find the right materials, how can you reduce weight and power and reduce fuel consumption?

"It's very simple!"
Guo Tailai laughed and talked about technical problems with his sister. Isn't this the reason why he asked the general to transfer his sister?
Can you talk about technical issues now?
The sister-in-law has a tighter hold. Anyway, the constant temperature of twenty-five degrees will not be hot. This smiles and explains: "I found that the impeller and the blades inside were split when disassembling the engine, in order to allow the blades to have Sufficient aerodynamic performance, the shape of the design is complex, and the processing is extremely difficult, which results in the blade being machined only once and then fixed to the impeller one by one."
"That's no way, this complicated blade shape leads to a high degree of precision in order to ensure perfect balance."
Of course, Zhao Wei knows this and nods his head. "The complicated shape also leads to the separation processing. The powerful CNC machine tools can't make the whole impeller blades of that shape. They can only be made in a single piece and then fixed in various ways. On the impeller."
"I can!"
Guo Tai smiled from the letter.
"what?"
Zhao Wei did not hear it at all, and asked again.

I can do the whole process.

Guo Tailai repeated it without hesitation:
The complete machining of the impeller and the blade does not require those fixed parts, which can make the blade have more complicated shapes.
With fewer fixed parts, the weight will be reduced, and better aerodynamic performance will result in better power and lower energy consumption.
When the impeller and the blades of each stage are integrated, not only will the weight be reduced..." "The volume will also decrease.

Zhao Wei directly wrote the following words for Guo Tai, and his tone was excited: "And because there are no connecting parts, it is more stable, more reliable, more durable, and fewer parts will make maintenance easier."
She has no doubt that Guo Tailai can do this. If there is one person in the world who can do it, then this person must be Guo Tailai, no doubt.
When I think of a smaller, lighter, but more powerful turboshaft engine, there will be an impulsive impulse. I can’t help but kiss Guo Tailai’s pro: "Fat, you really Baton!"
"of course!"
Guo Tailai admitted this without modesty.
"But, fat man."
After Zhao Guo’s kiss with Guo Tailai, he asked with a little concern:
Would you plan to produce these engines in the future?
You know, except for you, let alone domestically, it is impossible for anyone to produce such high-precision integral impeller blades.


There will be a way to produce it soon.

Guo Tailai smiled very happy: "Don't forget the projects that are being developed in my company."
Zhao Wei just looked down for a while, and his eyes turned out to be brilliant: "3d printing?"
"Correct!"
Guo Tailai is willing to talk to the teacher and sister. The two have a silent tacit understanding. This person speaks a word, and that person knows what is going on, and there is no need to explain anything.
Zhao Xiangbei once learned the tacit understanding of these two people, very envious and very pleased.
In the future, General Dynamics will upgrade the t700 series to t901 under the condition of technical conditions. Under the premise of using 3D printing technology, re-optimize the design through the combination of new materials and overall processing technology to get better engine performance. Reliability and durability.
In the Black Hawk helicopter, the t901 engine can increase the range by 161%.
The payload has more than doubled.
Similarly, Apache's improvements are equally jaw-dropping, with a new engine that can increase the range by 115%.
In the end, the t901 engine could mean more than 10 warriors or 93 shells on the Blackhawk, while Apache's flight time can be increased by 79 minutes.
Why not make such a powerful engine?
