Rule system
Chapter 446 The main design ends, the review team arrives
After Zhao Wei said that after the design idea, the R & D team argued against materials and design.
The design is still responsible by Sun Lei and Zhao Wei. Another person involved is Zhou Qing, Zhou Qing's interpretation, what is called heavy, he just said, Zhao Wei made a feasible plan for the idea expansion, he I don't know what to construct, design, and most of the time is downgrade.
However, Zhao Wei is still involved in Zhou Qing, after all, is the idea provided by Zhou Qing.
Research and development, the idea or creativity is the most important, there is no idea, there is no idea, but Zhou Qing is just offering ideas, but with his idea has designed.
This is R & D contribution.
The material is responsible for Li Rongmao and Zhang Hongtao. They need to study what materials meet the requirements, and listen to the performance, parameter indicators, etc. of the required materials, and they don't just list one, but to list a lot. , Make a analysis of the analysis report.
The next three days, the R & D group is doing this job.
It is designed to design three days.
In the end, they took out a solution for design and materials that met the requirements, and finalized the design of the air trunk.
So Sun Lei's design plan, only the last question is not solved -
Pipeline problem!
The compressor is in the intermediate position of the turntile manner, and the combustion chamber and turbine set are spaced apart from the jet, and the pipe is arranged in parallel, equal to the length of half of the engine.
This distance is too long.
Because the inner layer of the engine, it is necessary to withstand high temperature and pressure, the lowest is constructed from titanium alloy, and the piping of the above-top increases a lot of weight, and the power of the abandonment of the piston can be very limited. Even when it is running, it can achieve five% of the main jet, which is already the highest value.
This motivation is actually not low, because when the fighter is slow, it will greatly reduce the supply of fuel, and the auxiliary power provided by the aerated shutter can further reduce the fuel supply.
However, it is equivalent to the weight of the engine, and the pipeline is designed in parallel, and it will definitely not pay.
At the end of the root, it is still a design problem. However, the pipeline is not like a trunk, which can use very delicate design to make up for other issues. The straight line distance between the two points is the shortest distance, and the length issue is more subtle design, it is difficult to get hard. What is the effect.
Of course, the program is still there.
Yuan Haitao said an idea, he believes that the exhaust port can be placed directly in the secondary draft, and the turntile engine does not only have a flap. The internal main wind is the source of engine, and the internal parts are the main road. The outer layer of the service, the second-stage airway is mainly the purpose of the design of the design because the most exact square is too large, and the central compressor covers an area of too small.
When the flying speed of the fighter is very fast, the high-speed air can not pass all from the main road. The engine itself has become a huge resistance, so it has been designed with the second-level flap and the outermost three-stage fan.
When the wind is rising to a certain extent, the wind in the second-stage airway will be opened, and the air can be directly passed from the secondary wind to direct, the same is true, and the outermost three-stage airway will be opened.
If the ventilation vent is placed directly in the inside of the secondary airway, you can discharge the high pressure air directly to the secondary airway, and discharge the air in the air outlet position.
This idea is directly denied by Zhao Wei and Sun Lei, because the high-pressure air is placed in the secondary airway, it can't play the role of driving force, what is the significance of the previous design?
Therefore, the exhaust port of the deflated door can only be placed inside the level of the channel. It is best to discharge high pressure air to other functions, such as entering the combustion chamber to push the fuel burning.
"It is impossible to discharge into the combustion chamber."
Sun Lei shook his head directly. "The temperature of the combustion chamber is too high, and the high temperature will be in the exhaust of the exhaustion to the interior of the pipeline, which is easy to cause damage."
Zhao Wei's head, "The burning room does not have to consider, we still have to put the exhaust port, add the edge of the jet."
"It can be like this."
He carefully thought about it, "said," Rederate the outer layer of the main road, the outer layer of the secondary dragonfly, try to close the edge of the combustion chamber and the jet, reduce the weight that may increase. "
"Let's try it ~"
Zhao Wei took a role in R & D, others have no comments, because they are full of outsourcing for engine skin, there is no similar design work.
Therefore, everything depends on Zhao Wei himself, but for him, this design is not good, others need to consider the factors that need to consider the side, and there is enough conditions, he can easily get the ideal design structure, only With a day and a half, he took out a design.
This scheme is that the outer layer of the compressor is designed as an arc, since the burning room on both sides is small, the compressor forms a semi-wrapped structure to the combustion chamber, and the exhaust pipe of the valve can directly cross the combustion chamber. The outer layer of the thick turbine group arrived at the edge of the jet.
Although it is still a straight line, the length of the pipe is greatly reduced, only one quarter, it can be designed in the inner bag - skin, and no additional assumption of one layer is required.
Of course.
Because the inner layer increases the pipeline, it must thicken the relevant part, and the total weight still increases.
"Only one-tenth of the expected expectation, and the power and stability that can be provided can also be accepted."
Sun Lei concluded after calculation.
Zhao Wei is very light. After he is designed, it has already known the result. It does not have any difficulty for him. He just took the design to others, symbolizes them to mention the opinions, let everyone add it. Participate.
The best result is all throughout.
If someone has made opinions, there is no relationship, and the appropriate simple explanation is good.
Here.
Sun Lei's design plan, all of the questions were corrected.
This set of designs is fully finalized, the Celebration of the R & D group, everyone comes to celebrate Sun Lei's success, a set of design can be successful, and Zhou Qing also has a bit of 'credit', he is more than Sun Lei Be envied, because he is really just saying that Sun Lei is designed and completed through the development. After the Kunlun two groups, it has worked more than 12 hours a day, it has worked hard.
Zhao Wei will make everyone will continue to work hard. "We strive to solve the problem, design a new, top fan engine!"
"This project is dragging too long."
He said very seriously. "I really want to finish it. The rest of the work is not much, work hard, come on ..."
Zhao Wei's encouragement is from the heart, but most of others do not understand.
"The project dragged too long?"
"how long?"
Sun Lei asked with doubt, "As far as I know, the Kunlun two groups just set up?"
Zhou Qingdao, "You are late, Zhao's time, it should be a model from us."
"How long is it now?"
"It's almost half a year, we have come in March after the year, and now it is in September!" Zhou Qing replied very serious.
"Half year?
Sun Lei is soaring that I don't know what to say.
The Wangwu engine group is from the Kunlun engine group. When you come out, you will bring a large number of people and technologies. Their jobs are only revised, improved, and the results have been used for more than eight years of design. Subsequent Make a prototype, and now we can assemble the fighter, still far, it feels least two or three years.
Yanhua University has studied the Kunlun sample for half a year, and the core turbine blade materials have been completed, but also demonstrates the design of the compressor to ventilate the door, and the results can be said to be very good.
However, complete the design?
"There are still many jobs in the next year, according to this progress, the fastest, fastest, will you still have a year?"
Sun Lei is calculated in accordance with Zhao Wei's work efficiency, it is a kingstone engine group. Don't say it is a year, then give it three, five years to design a fixed type, it is already acceptable.
......
Sun Lei went to the speed of Zhao Wei, because he didn't understand Zhao Wei's working method.
Next is the internal blade design, including turbine blades, booster blades, and seafloid leaves in the front section, as long as it is a component on the spindle, it is designed as a whole.
This must be used to use Wang Zhiguo's combustion room motivation argument.
After Wang Zhiguo came to Yanhua University, he quickly became a neglected person, but his work is full, because he heard that the blade motivation of the material or more materials, the power group feels there is no meaning, even The same is true. I didn't expect it for a long time. I heard Zhao Wei led the team to develop a nickel alloy turbine blade with high temperature of more than 1700 degrees. His work suddenly became very valuable.
Therefore, Wang Zhi's work has always been very hard. He spends a lot of time, and it is slightly filled for the ability and experience in experience, and took out a rigorous design.
After Zhao Wei took the design plan, I only had a good correction for only one night.
Dynamic control scheme rapidly.
Zhao Wei praised Wang Zhiguo's work, but also gave him a bonus, equivalent to a public encouragement, and immediately entered the design of the spindle blade.
This work is too complicated.
The main shaft is the design core of the scroll engine, the pressurizing blade, and finally provides powerful turbine groups, and the seaflets of the previous section are very complex. In the design diagram of the Kunlun engine, the construction of the three leaves is three kinds of leaves. Construction, explanation, Just dozens of pages.
But detailed design instructions have brought enough conditions to Zhao Wei, and what he did is not redesigned, but on the basis of design, appropriate improvements.
This is OK.
In fact, the Kunlun engine team 'score' is the highest work, which is in the design of the spindle, because the main shaft function is designed, subject to material restrictions, the effects of fine-working manufacturing processes, the design purpose of the supercharged blade is only for boost, turbine group Just rotate the spindle under the combustion power drive.
If the most perfect spindle design is a hundred points, the international top engine spindle design can get 90 points, the main shaft design of the Kunlun engine group, can also get more than 75 points.
Zhao Wei needs to do only on the basis of the original design, with the improvement of combustion chamber power, the performance of turbine blade material, and use "supervisory law" to find unreasonable and affected places, everywhere Improvement, the spindle design can improve.
After a dozen improvements have been made continuously, Zhao Wei scored more than 90.
It is already perfect now.
If you want to further improve, it is necessary to be affected by the material and exquisite process, that is, it is designed and can't be manufactured. The improvement is meaningless.
The burning chamber is good.
Turbine blade, turbine group has.
The pressurized blade of the compressor is well designed, and the internal outer skin materials and new design are connected, and the remaining is just a stator blade, and the argument of other auxiliary functions.
Sun Lei said that there is a new alarming alarm plan, does not need to design movable stator blades, Zhao Wei also agrees with this statement, but the reason is not to provide enough stability, but the design of the stator blade itself, It can help increase stability, and the design is not necessarily to move the stator blades, but increase some curved, apertures inside to prevent high pressure air inverted in the low pressure cassette in the outside.
In the office.
Zhao Wei has studied the static blade. I hope to take out the best solution. Similar design is easy for him. It only needs enough conditions, he can take out a very good solution.
In the continuous study, he quickly took out a set of schemes, using a large bending structure, with the design of the microporous design, allowing the stator blades to play the wind speed, also prevent the reverse flow of high pressure air, After he found out the program, he quickly recorded the contents of the brain. After the engine design, he found that his own drawing capabilities have improved a lot, that is what he drawn, not a single single Rely on systematic capabilities, let yourself know how to "out pen '.
When the last one was completed, Zhao Wei looked at the design map on the paper, could not help but show a satisfactory smile. He has long stretched a lazy waist, and I feel that I can relax.
Now the main core of the engine is designed, only the problem of control system, accessories, etc. are left.
These problems can slowly solve slowly, as long as the main design of the engine can begin production prototypes, after the prototype will improve, to add a supporting auxiliary function, and can also perform a test of engine debugging operation.
The current is summarized together, and the report is required to be reviewed, then the application is applied.
The door was suddenly knocked.
"Zhao's academician." The outside of the outside shouted, it was obviously Yuan Haitao.
"Into!"
Yuan Haitao pushed into the door, he was a bit rushed, "Zhao Academician, how are you still here, the review team is coming."
"Review Group?"
"Aviation Group, also have a scientific and technological office, the materials, Kunlun group, and composed of the review group?" Yuan Hai Tao Road, "I still said a few days ago, they came together to conduct an initial review of the projects in the Kunlun group, I felt It is the day after tomorrow, I didn't expect to come today, I also came to a sudden attack ... "
Zhao Wei thought, it seems that Yuan Haitao said that the superior will send a review group, 'Review' sounds very serious, in fact, the review is for the project, that is, to see the R & D environment, project participants, etc. Let's take a look at the needs of the two groups of Kunlun.
Because the project is Zhao Wei's application, it has been strongly supported by the aviation group. The superior team came over as a review. In fact, it is to look at a circle, and it is necessary to see if there is any demand in the two groups of Kunlun.
For example, talent, funds.
If it is a more expensive, and the person who is in the examination team is definitely a good opportunity.
Zhao Wei does not need more funding, and I don't think there is any use of the review, but after all, it is the superior party to see the project ...
"The time is also right!"
"Just ask them, how to put the engine design, how to review the design, how to contact the production sample, how much time it takes ..."
Zhao Wei suddenly looked forward to standing, and Yuan Haitao went out.
