Chapter 53: Do good deeds without worrying about the future
During the meal, everyone was very enthusiastic. After all, they had solved a big problem, and it seemed that a number of big problems could be solved. They were all very happy.
General Manager Wang and Gao Zhendong chat a lot. After all, they are both purely technical backgrounds, and it seems that Gao Zhendong is responsible for researching this material, which makes Mr. Wang feel closer to him.
Gao Zhendong is also very interested in Aviation Development. In his previous life, he often wandered around the military sections of major forums and post bars. When it comes to the past of Aviation Development, he is definitely not as clear as Chief Engineer Wang, but Aviation Development He knows much better about the future than Mr. Wang.
So the two of them chatted quite lively.
Speaking of jet engines, Gao Zhendong couldn't hold back and asked Mr. Wang: "Mr. Wang, do you think it is possible to drive a fan to blow air backwards in addition to using gas to drive the compressor?"
Mr. Wang also said Without answering, a young engineer from LYP-6 laughed: "Technician, what is the difference between this and blowing air directly backward? There is also an efficiency problem in the conversion of the jet to the fan, and the energy loss is more."
< br>This time before Gao Zhendong answered, Mr. Wang scolded him first: "If you don't understand, then stop talking nonsense."
After scolding, Mr. Wang turned to Gao Zhendong and said: " Zhendong, in addition to metallurgy, have you also studied aviation? You are not something an outsider can ask."
Gao Zhendong shook his head: "No, no, I studied automation, that's just me. Just thinking about it. I just thought that according to the rules, the higher the temperature of the gas, the higher the pressure. The higher the pressure, the higher the flow rate. If the flow rate is higher, the deceleration process during the injection is not enough. The loss will be large and the efficiency will be low, so I thought about using a turbine to drive one or more stages of fans to recover part of the gas kinetic energy and reduce the exhaust speed to a suitable speed. This would increase the efficiency. Will the fuel consumption be reduced, and the fan thrust can also be increased? ”
As soon as these words came out, Mr. Wang's eyes lit up: "Automation? If you accept it, you will be awesome. Zhendong, you have a high technical sensitivity. You are right. Now there is an engine called a turbofan engine. It's you. That's what you said, but we don't have any installation target, so we haven't started research yet."
After speaking, he turned his head and continued to scold his own people: "Listen to me, you are ignorant and have no skills. Professionals have sharp minds. "
Gao Zhendong was no longer sleepy. It was not that he wanted to continue to watch Mr. Wang curse, but that he remembered a flaw in the scientific research system of this era that was often discussed in his previous life - Matching.
To put it simply, some equipment, because it is imitation or planning reasons, depends on its installation or use object. If this object is discontinued, then the device will also be discontinued.
If it is special dedicated equipment, it is okay, and there is nothing wrong with it. However, for general core equipment like engines, this system will bring great waste, and all the previous work will be in vain.
For example, after the Laowuye bomber's improvement plan was discontinued, the supporting Type 5 turbofan engine was discontinued.
Thinking of this, Gao Zhendong wanted to say what he wanted to say no matter what, especially when the leader of the 17th Machinery Department was also there. Of course, he didn’t think too much about the outcome. He just felt that You should just say it yourself.
——But do good deeds and don’t ask about your future.
Thinking of this, Gao Zhendong pretended not to understand: "Supporting? Isn't the engine a universal equipment? Must it be a supporting project or installation target?"
"I just joined the work, I don't understand very well. But I think as long as the engine is good enough, it can still be studied even if the target of installation is gone. Just like the combat mech was disbanded for some reason, it is not impossible to use its engine on fighter B with similar thrust requirements. Or if one engine is installed, it will be a light fighter, and if two engines are installed, it will be a heavy fighter. Wouldn't this simplify logistics?" Mr. Wang was still thinking carefully about Gao Zhendong's words, but the leader of the 17th Aircraft Department became interested. He had a good impression of Gao Zhendong and had been paying attention to him. After hearing his words, he thought about it carefully and found it interesting.
"Hey, Zhendong, we have also considered the issue you mentioned, but we haven't thought it through yet. Don't be afraid of making mistakes and tell us what you think." The leader put down his chopsticks and encouraged Gao Zhendong.
Gao Zhendong pretended to be embarrassed and rubbed his head: "Hey, I'll just say it, it's a family story, leaders, please don't mind."
"I just think that when a main product is discontinued, it must be promoted It’s a pity that a batch of general-purpose equipment has also been discontinued. Is there some equipment that has been evaluated and has good general-purpose equipment that can continue to be developed?” After talking about one situation, Gao Zhendong continued to talk about the second one.
“Or some equipment that is technically difficult, demanding, and very complex. Take Mr. Wang’s engine as an example. Generally speaking, the research time for this kind of thing is very long. We can wait until it is needed. It is often a matter of urgency. Is it possible to set up separate projects for the engine and the corresponding model? ”
An engineer of LYP-6 asked: "How to solve the suitability and usability?"
Gao Zhendong answered quickly: "First, make a good plan, such as what specifications of engines are needed, and fully Argument, strict planning, and once the plan is determined, carry out it unswervingly, so that when needed, even if the thing you come up with is not the most appropriate, it will at least be usable."
"Second, Establish good interfaces between systems at all levels. The interface I am talking about here does not refer to the aviation plug interface, but stipulates a set of standard specifications, including functions, performance, installation, maintenance, etc., no matter what is used If it is implemented by means and conforms to this interface, it can be used.”
Then Gao Zhendong also gave himself an example: “Take this 3Z-591 as an example. This material was originally intended for use. It was trial-produced in conjunction with another of our scientific research projects. I didn't think of this at the time, so I just put it in that project as ancillary materials. The factory leaders had a strong view of the overall situation and asked me to use it as a separate project for research. He said that the project is still in the later stages of testing, but this 3Z-591 has already produced results and has not been affected by that project at all."
The words naturally praised the factory, but this does not count. Flattery, it was indeed Lao Chen who asked him to take out the project separately.
Although he didn't speak much, the eyes of those present could be heard. The leader thought for a long time, picked up the cup and smiled: "Zhendong is worthy of being the person who created 3Z-591. He spans multiple majors and has excellent technology. This scientific research idea is also It's very clear. I learned it. I learned it. Your words also gave me a lot of inspiration. Come on, I'll give you a toast. It's like paying the tuition."
Gao Zhendong said humbly, He stood up, picked up the cup and drank it all in one gulp. Of course, he didn't do any of Xu Damao's "one leader and three me" stuff.
But Mr. Wang looked happy to see Hunter, and turned to Director Yang: "Director Yang, we are short of people there, how about..."
He hasn't said anything yet. After finishing, Director Yang laughed and rejected: "Mr. Wang, stop it. It's okay for you to come to my place to get materials, but if you want to make people leave, there's no way."
The people in the room continued to laugh and laugh, and finally Leave happily.
When the leader left, Director Yang got into the car. Standing beside the car, the leader said to Director Yang: "This Zhendong is a talented person. He must increase his burden appropriately and don't waste it."
