Qiu Wen'anhui reported: "Boss, this is the design information about the ground interview desk. We sorted it out and sent it over to ask the boss to help us check it out."

Senior aviation engine designers must know the construction and design of test drive tables. Even if they are not very proficient, they will definitely know a lot. Qiu Wen'an and Sun Xiaoping both understand these, among which Sun Xiaoping is relatively proficient, and can be said to be an expert in this field.

In terms of pure aviation engine design, Qiu Wen'an is half the price. If we talk about the construction and design of the aviation engine test bench, Sun Xiaoping is half the price than Qiu Wen'an.

The construction and design of the aircraft engine test bench, both of them had communicated with Li Tianfeng before. Li Tianfeng's professional level in this aspect was greatly impressed by the two. They often thought to themselves, what aspects does the boss not understand?

As long as it is about aircraft engines, whether it is design, manufacturing, or testing, Li Tianfeng has shown extremely high professional attainments. So, the two of them sent the construction and design materials of the test drive table together, and Qiu Wen'an even used the words "please check the boss."

Li Tianfeng looked through these materials and listened to the reports of the two people. He thought to himself that the construction of the ground interview stand for the turboshaft engine would soon need to be fully started.

The test of an aircraft engine not only requires testing a large number of main parts, components and systems, but also conducting a series of tests on the entire engine. Such tests are also called test drives, also known as ground interview drives.

Aero engines work under extremely harsh conditions such as high temperature, high pressure, high speed and high load. This requires special tests and testing equipment to test the performance, reliability and durability of the engine. The test of engines across Taiwan is also called engine test drive.

In order to ensure the reliable work of the engine and its system, a variety of rigorous tests must be carried out. Although the design and calculation methods are developing very fast at present, it is still impossible to take into account all the complex situations that may be encountered in the actual work of the engine. Therefore, it is impossible to develop a reliable and technologically advanced aircraft engine without the test. The experience and data accumulated by a large amount of tests are an important basis for improving the design and calculation methods. Engine test runs must be carried out.

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

Ground testing equipment is called ground environment simulation test bench, also known as ground interview bench. High-altitude simulation test equipment is called high-altitude environmental simulation test bench, also known as high-altitude table. Flight testing equipment is also called flight test bench.

Li Tianfeng is currently building a ground interview stand. The information sent by Qiu Wen'an and Sun Xiaoping is also about the ground interview stand. As for the high-altitude stands, flight test stands, etc., the things are highly technical and require a lot of funds, so they can only be constructed in the next stage.

The ground interview table is for aircraft engines to be tested under ground conditions. The ground interview table is mainly composed of the following parts.

The test workshop is mainly composed of the engine's force measuring bench, inlet and exhaust system. The force measuring bench of the piston aircraft engine, turboprop engine and turboshaft engine should be able to accurately measure torque. If it is the force measuring bench of the jet engine, it should be able to accurately measure thrust.

The control room, also known as the control room. There is a strong noise of more than 100 decibels during engine testing, and there is also a certain danger. Therefore, there is a separate control room that can be sound insulation and has certain protective measures for the tester to control and monitor the engine's work.

Test equipment room, in which various testing equipment is arranged.

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

After listening to the report from both of them, they also looked at the information. Li Tianfeng said: "The design and construction plan are good. You even made all the building floor plans. It is rare, but some places still need to be improved..."

Li Tianfeng combined his knowledge and said a lot of things that needed to be improved and perfected. The two listened carefully, and after listening, they looked at each other, full of admiration, and thought to themselves that the boss is worthy of being the boss. After saying this, they suddenly felt enlightened.

After talking about this, Li Tianfeng divided the work again, "Mr. Qiu, your main energy is currently focused on the development of our 'tfwz001' type turboshaft engine. Mr. Sun, your main energy is temporarily focused on the interview bench and is responsible for the design and construction of the test workshop."

The two nodded. This arrangement fully utilized their strengths.

Seeing that both of them were quite satisfied, Li Tianfeng nodded and said, "Mr. Sun, the land for the construction of the test workshop has been approved, and the start-up work can be started. If you have any questions, please contact Vice President Sun Kang."

Executive Vice Mayor Guo Tongde was good. A piece of land that Li Tianfeng liked was quickly approved. This piece of land area was more than 200 acres, and the construction of a test workshop was enough. If Li Tianfeng liked this piece of land, it would be natural that this piece of land would not be wrong.

First of all, the transportation is good. It is not far from the current Tianfeng Technology, only a few kilometers away, and there is a spacious asphalt road. Although the transportation is convenient, the location is a bit off. It is just right for the test workshop to be built, so there is no need to worry about noise disturbing the public.

Tianfeng Technology has built a large-scale construction area and a large-scale construction. In order to adapt to such construction work, Sun Kang, the deputy general manager of Tianfeng Technology, personally served as the general manager of the infrastructure department, and was responsible for the comprehensive construction of the entire Tianfeng Technology. Because the Infrastructure Department was established, there were 20 or 30 people under his command, Sun Kang was 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 allocating the work of the two people and explaining some work matters, Li Tianfeng said: "Mr. Qiu, we should work hard on the research and development of our 'tfwz001' type turboshaft. I may be away for a while in the past few days."

Thinking of the phone call with Wang Ruobing just now, Li Tianfeng felt a little anxious and worried. He didn't know if Wang Ruobing had found his grandfather. Also, if he agreed to see him, if he didn't want to see him, everything would be useless. He might just watch Wang Ruobing marry into the Duan family.

Qiu Wen'an and Sun Xiaoping looked at each other, and obviously noticed that Li Tianfeng's face had changed. Li Tianfeng obviously had something to worry about, and it might seem like something tricky. After the two of them looked at each other, they stood up and left with tactfulness.

Watching the two of them leave their office, Li Tianfeng's mind was filled with Wang Ruobing, and his worries and uneasiness became increasingly intense. He didn't know how the capital was going.

………

Capital.

Wang Ruobing was also anxious and could only wait. At least he would have to wait until night before he could meet his grandfather. During the day, his grandfather was busy with state affairs, so it was impossible for him to see him.

Anxious and uneasy, it is no exaggeration to describe Wang Ruobing as an ant under the hot pan.

night.

Wang Ruobing saw the lights on in his grandfather's study from afar, immediately took a deep breath, and then walked towards the study.

It is rare to come to my grandfather's study every year, but this is the second time I have come here in these days. When I walk to the door of the study, I remember my grandfather's usual majesty. Wang Ruobing felt inexplicably nervous. After hesitating for a long time, he gritted his teeth and plucked up the courage to knock on the door.

"Come in!"

A majestic, familiar voice came out. Wang Ruobing pushed the door and walked in with this nervous mood. Wang Ruobing saw a piece of rice paper on the huge mahogany desk. His grandfather was writing, and a few vigorous words were vividly displayed on the paper, which was very skillful.

Wang Guohong was chanting carefully without raising his head, which made Wang Ruobing even more nervous and uneasy, and he couldn't help but scream softly: "Grandpa!"

It was just enough to finish the writing. I looked up and saw Wang Ruobing. What surprised Wang Ruobing was that his grandfather was actually very kind and said with a soft smile: "Ruobing, come and sit down. Have I figured out what I said to you?"

Wang Ruobing gritted his teeth and plucked up the courage again: "Grandpa, that Duan Hongju is a big villain. You will ruin your granddaughter's happiness for the rest of your life. I will never agree."

"Oh." Seeing Wang Ruobing's tone showing firmness, Wang Guohong was slightly surprised that his granddaughter was usually gentle and generally would not be like this. Could it be that so-called love?

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

Wang Ruobing nodded and said, "Grandpa, they are completely incomparable." After thinking about it, Wang Ruobing still said, "Grandpa, I only have Li Tianfeng in my heart, and I can no longer tolerate a second person."

Upon hearing this, Wang Guohong was thinking. After thinking about it, Wang Guohong said, "Ruo Bing, you must have been talking about these things to me this time, tell me, what's wrong?"

Wang Ruobing said: "Grandpa, Tianfeng wants to meet you and want to talk to you."

Upon hearing this, Wang Guohong was slightly stunned. Unexpectedly, Li Tianfeng took the initiative to ask to see him and couldn't help but say, "Young man has a commendable courage, but I don't have time these two days, so I'll talk about it later."

"grandfather!"

Wang Ruobing was really a little anxious. He couldn't tell whether his grandfather really had no time or did not want to see Li Tianfeng. If he really didn't want to see Li Tianfeng, the situation would be very bad. His grandfather didn't want to see Tianfeng, so why not talk about the matter between him and Tianfeng?

Thinking of this, Wang Ruobing almost burst into tears.

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

His grandfather could not resist. Wang Ruobing's eyes turned red, and two bean-sized tears came down. He covered his face and cried. Wang Ruobing ran out of the study in tears.

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