Qiu Wenan reported: "Boss, this is about the design information of the ground interview platform, we sorted it out and sent it over to let the boss help us check it." ≥ ≥ point≥ little ≥ said, x."

Senior aero engine designers must understand the construction and design of the test bench, even if they are not very proficient, they will definitely understand a lot, and Qiu Wenan and Sun Xiaoping both understand these, among them, Sun Xiaoping is also relatively proficient, it can be said that he is an expert in this field.

In terms of pure aero engine design, Qiu Wenan is half a chip, and if it is said that the construction and design of the aero engine test bench, Sun Xiaoping is half a chip ahead of Qiu Wenan.

The construction and design of the aero engine test bench, the two of them have communicated with Li Tianfeng before, and Li Tianfeng's professional level in this aspect has greatly impressed the two, and the two often think in their hearts, what else does the boss not understand?

As long as it is about aero engines, whether it is design, manufacturing, or testing, Li Tianfeng has shown extremely high professional attainments.

Li Tianfeng looked through these materials, listened to the reports of the two of them, and thought in his heart that the construction of the turboshaft engine ground test platform would need to be fully launched soon.

The test of aero engine must not only test a large number of major components, components and systems, but also carry out a series of tests on the whole engine, which is also called test run, also known as ground test run.

Aero engine is working under extremely harsh conditions such as high temperature, high pressure, high speed and high load, which must use special test and test equipment to test the performance, reliability and durability of the engine.

In order to ensure the reliable operation of the engine and its systems, a variety of rigorous tests must be carried out. At present, although the design and calculation methods are developing rapidly, it is still impossible to take into account all the complex situations that may be encountered in the actual work of the engine, so it is impossible to develop a reliable and technologically advanced aero engine without the test. The experience and numbers accumulated from a large number of experiments are an important basis for improving design and calculation methods. Engine test runs are mandatory.

The test run of the engine is an important process, and the engine test is divided into ground test equipment, high-altitude simulation test equipment and flight test equipment.

The ground test equipment is called the ground environment simulation test bench, also referred to as the ground test bench. The high-altitude simulation test equipment is called the high-altitude environment simulation test bench, also referred to as the high-altitude platform. Flight test equipment is also known as flight test bench.

Li Tianfeng is currently going to build a ground interview platform, and the information sent by Qiu Wenan and Sun Xiaoping is also about the ground interview platform. As for the high-altitude platform, flight test bench, etc., that thing is highly technical. A lot of money is needed, and construction can only be carried out in the next stage.

The ground test bench is used for aero engines to test under ground conditions, and the ground test bench is mainly composed of the following parts.

The test workshop is mainly composed of a force measuring bench for installing the engine and an intake and exhaust system. Force benches for piston aero engines, turboprop engines and turboshaft engines should be able to measure torque accurately. In the case of a jet engine, the force measuring bench should be able to measure thrust accurately.

The control room, also known as the control room. There is a strong noise of more than 100 decibels during the engine test, and there is a certain danger, so it is necessary to have a separate control room that can be soundproofed and has certain protective measures for the test personnel to control and monitor the work of the engine.

Test equipment room, where various test equipment is arranged.

Test bench system. Including control system, fuel control system, water and electricity supply system, etc.

After listening to the reports of the two and looking at the materials, Li Tianfeng said: "The design and construction plan are good, you have even made the building plan, which is rare, but there are still some places that need to be improved......

Li Tianfeng combined his own knowledge and said a lot of things that need to be improved and perfected. The two listened attentively, after listening. The two glanced at each other, their hearts were full of admiration, and they thought in their hearts that the boss deserved to be the boss.

After that's all that has been said. Li Tianfeng divided the labor again, "Mr. Qiu, your current main focus is on the development of our 'TFWZ001' turbine shaft engine. Mr. Sun, your main focus is temporarily on the interview platform, responsible for the design and construction of the test workshop. ”

The two nodded. This arrangement can be regarded as giving full play to the strengths of the two.

Seeing that the two of them were more satisfied, Li Tianfeng also nodded, and then said: "Mr. Sun, the land for the construction of the test workshop has been approved, and the start-up work can begin, if there is anything, please contact Vice President Sun Kang." ”

Executive Deputy Mayor Guo Tongde is good, Li Tianfeng Xiangzhong a piece of land was quickly approved, this piece of land covers an area of more than 200 acres, the construction of a test workshop is enough, Li Tianfeng can phase this land, this land will naturally not be wrong.

First of all, the traffic is good, not far from the current Tianfeng technology, only a few kilometers, there is a spacious asphalt road directly, although the traffic is convenient, but fortunately, the location is a little biased, just to build a test workshop, do not worry about noise disturbance.

Tianfeng technology large-scale, large-scale construction, in order to adapt to such construction work has been set up infrastructure department, Sun Kang, the deputy general manager of Tianfeng Technology personally served as the general manager of the infrastructure department, responsible for the overall construction of the entire Tianfeng technology, because of the establishment of the infrastructure department, there are twenty or thirty people, Sun Kang is much easier than before.

The construction of the test workshop involves a lot of infrastructure construction, so Li Tianfeng asked Sun Xiaoping to take the initiative to contact Sun Kang.

After assigning the work of the two and explaining some work matters, Li Tianfeng said: "Mr. Qiu, we should pay close attention to the research and development of the 'TFWZ001' turbine shaft, and I may leave for a period of time in the next few days." ”

Thinking of the phone call with Wang Ruobing just now, Li Tianfeng felt a little anxious and worried in his heart, I don't know if Wang Ruobing has found his grandfather, and whether he agrees to see him, if he doesn't want to see himself, that will be in vain, and he may only watch Wang Ruobing marry into the Duan family.

Qiu Wenan and Sun Xiaoping glanced at each other, obviously noticing the change in Li Tianfeng's face, Li Tianfeng obviously had something on his mind, and it may still seem to be some tricky matter, after the two glanced at each other, they got up and retreated.

Seeing the two of them leave his office, Li Tianfeng's mind was full of Wang Ruobing, and the worry and anxiety in his heart became stronger and stronger, and he didn't know what was going on in the capital.

………

Capital.

Wang Ruobing was also anxious, he could only wait, at least he would not be able to meet his grandfather until the evening, and during the day, his grandfather was busy with state affairs, and it was impossible for him to see him.

Anxious and uneasy, it is not an exaggeration to describe Wang Ruobing as an ant under a hot pot.

At night.

Wang Ruobing saw the light in his grandfather's study from a distance, and immediately took a deep breath, and then walked in the direction of the study.

His grandfather's study, usually, it is rare to come once a year, but this is the second time in the past few days, walking to the door of the study, thinking of his grandfather's usual majesty, Wang Ruobing was inexplicably nervous in his heart, and after hesitating for a long time, he gritted his teeth and mustered up the courage to knock on the door.

"Come in!"

A majestic, familiar voice came out, Wang Ruobing was in such a nervous mood, pushed the door and walked in, Wang Ruobing saw that on the huge mahogany desk, there was a piece of rice paper, his grandfather was waving, and a few vigorous big characters jumped on the paper, which was very skillful.

Wang Guohong was waving his heart without raising his head, which made Wang Ruobing even more nervous and uneasy, and couldn't help but call softly: "Grandpa!" ”

I just finished writing, put away the pen, looked up and saw Wang Ruobing, what made Wang Ruobing strange was that his grandfather was actually very kind, and said with a soft smile: "Ruobing, come, sit, I have thought about what you said clearly?" ”

Wang Ruobing gritted his teeth, and once again mustered up his courage and said: "Grandpa, that Duan Hongju is a big villain, you will bury your granddaughter's happiness for a lifetime, I resolutely refuse." ”

"Oh." Seeing that Wang Ruobing's tone was firm, Wang Guohong was slightly strange, this granddaughter of his is usually gentle, and she usually doesn't do this, is it really the so-called ** love.

Wang Guohong said: "Ruobing, is that Li Tianfeng so good?" That Duan Hongju is worthless like this? ”

Wang Ruobing nodded, and then said, "Grandpa, the two of them are completely incomparable." After thinking about it, Wang Ruobing still said: "Grandpa, I only have Li Tianfeng in my heart, and I can't tolerate a second person." ”

Hearing this, Wang Guohong was thoughtful, and after thinking about it, Wang Guohong said: "Ruobing, you definitely didn't talk to me about these things this time, let's say, what's the matter?" ”

Wang Ruobing said: "Grandpa, Tianfeng wants to see you and wants to talk to you." ”

Hearing this, Wang Guohong was slightly stunned, but he didn't expect Li Tianfeng to take the initiative to ask to see him, and couldn't help but say: "The young man's courage is commendable, but I don't have time for the past two days, and I will talk about it when I have time in the future." ”

"Grandpa!"

Wang Ruobing is really a little anxious, he can't tell if his grandfather really doesn't have time, or he doesn't want to see Li Tianfeng, if he really doesn't want to see Li Tianfeng, then the situation is very bad, his grandfather doesn't want to see Tianfeng, how to talk about the matter between himself and Tianfeng.

Thinking of this, Wang Ruobing almost cried.

"Ruobing, go back and rest." After speaking, Wang Guohong waved his hand.

His grandfather's words were not allowed to resist, Wang Ruobing's eyes were red, and two bean-sized tears came down, hiding his face and crying, Wang Ruobing ran out of the study crying.

Looking at Wang Ruobing's back, Wang Guohong felt an inexplicable pain in his heart, and said in his heart, Ruobing, I hope grandpa is right this time.

Today's three watches, the second one is sent!

I don't stop coding two chapters in a row, my braincase is a little dizzy, take a break, and continue to work in the afternoon! (To be continued......)
