The completion of the turbofan 20 engine may be several months ahead of the expected time, Zhang Haiping is very happy, on the other hand, it also reflects the strong technical strength of Tianfeng Technology Company.

Zhang Haiping even thought in his heart, Tianfeng Technology Company has strong technical strength, and the military's equipment should be replaced and upgraded one by one.

For example, our fighters, the current J-10 and J-11 are the main forces, and although the J-20 is under development, it is facing a series of problems. For example, our military transport aircraft, the old and backward Y-8 is actually the main model of the domestic transport aircraft in service. For example, bombers still use old bombers.

Although the Y-8 and H-6 are equipped with relatively advanced engines, that is, they are fully converted into turbofan 16 engines, but compared with the requirements of the military, especially compared with the active transport aircraft and bombers of Russia and the United States, the gap is still very large, which is extremely inconsistent with China's image as a military power.

Thinking so happily in his heart, Zhang Haiping said with anticipation: "Mr. Li, you can complete the comprehensive design of the turbofan 20 engine so quickly, which greatly exceeds our expectations, and it also reflects your strong technical strength. ”

Li Tianfeng was embarrassed, and immediately said: "Minister Zhang, you really look up to us, the current Tianfeng Technology Company, our staff scale can reach 20,000 people, compared with the world's aviation industry giants, the gap is still far away, we can only come step by step." ”

After thinking about it, Zhang Haiping could only suppress his enthusiasm and said slowly: "Mr. Li, I was a little anxious just now, yes, let's come step by step." The beginning of one project after another, from easy to difficult, but this time you have done a really good job in the design of the turbofan 20 engine, and I want to ask for credit for you. Reward you. ”

It is a great honor to receive the commendation of the military, and Li Tianfeng was very happy to hear this: "Minister Zhang, then thank you in advance, rest assured, we will strive to complete the comprehensive design of the turbofan 20 as soon as possible, and then enter the trial production stage of parts as soon as possible, and develop this engine as soon as possible." Mass delivery to the military as soon as possible. ”

Zhang Haiping said: "Okay, okay, I'm waiting for your good news." ”

After chatting with Zhang Haiping for a long time, Li Tianfeng was very good, and the military's commendation also made Li Tianfeng's heart full of expectations.

If the turbofan 20 engine is fully designed, the next stage is the trial production of various parts, but Li Tianfeng knows. Because many parts are similar or even identical to the turbofan 16 engine, the trial production process of the parts will not take long. It's definitely a lot shorter than a brand new engine part trial time.

Before the engine is fully designed, the key electronic components that Li Tianfeng expects have also been delivered to Tianfeng Technology Company, which is the first batch of samples, and a series of tests and performance verification and performance testing are still needed.

However, even if it was the first batch of samples, Li Tianfeng was inexplicably happy. I think that at the beginning, others still wanted to jam their necks from this, and engage in a series of small actions behind their backs, trying to make Etra completely terminate the contract with them.

Thankfully, after hard work. Tianfeng Technology Co., Ltd. and Etra Co., Ltd. renewed their contracts for another year, and there is no need to worry about these imported electronic components for the time being.

It is the best to be able to completely localize, the full-function electronic digital control system of the turbofan 20 engine, first to achieve localization, all spare parts, not Tianfeng Technology Company's own production, or domestic procurement.

If Gu Qingguo's batch of electronic component samples can meet their own requirements, Li Tianfeng is ready to fully localize the electronic control systems of turbofan 16, turbofan 17, turbofan 18 engines, as well as turboshaft D and turboshaft E engines.

Tianfeng Technology Co., Ltd., an electronic laboratory.

This is a high-standard laboratory, located in the technical center building, where several technicians in white coats are testing and testing these electronic components.

In the laboratory, it is spotless, the windows are bright and clean, this is a dust-free laboratory, and the equipment and instruments in the laboratory are first-class.

Bai Lijie is a returnee doctor, who used to work in a well-known company in the United States, and is now the director of the first electronic laboratory of Tianfeng Technology Company.

There are several models of this batch of samples, two or three pieces of each, Bai Lijie wore snow-white gloves and put one of the electronic components into the testing instrument.

Next to Bai Lijie, there are also schematic drawings and design drawings of this electronic component, among which the performance requirements and technical requirements have been clearly specified on these drawings.

Bai Lijie said to several young people next to him: "Xiao Guo, you adjust the parameters of the instrument, Xiao Cai, you will pack the No. 6 piece to be tested, Xiao Liu, you ......"

Under the command of Bai Lijie, everyone was orderly and busy, and after some preparations, Xiao Guo reported: "Director, everything is ready, you can start testing." ”

"Hmm." Bai Lijie nodded, then pressed a button to start the performance test of this electronic component.

On the display screen of the instrument, a series of performance parameters soon appeared, and there were also performance parameter curves.

Outside the laboratory door, Li Tianfeng and Sun Xiaoping changed their shoes, put on a white coat, and entered the laboratory after taking a wind bath.

found the two, and everyone greeted each other, "Mr. Li is good, Mr. Sun is good." ”

Li Tianfeng nodded, and when he saw that Bai Lijie was seriously testing, he couldn't help but smile, and Bai Lijie obviously also found Li Tianfeng and Sun Xiaoping, and immediately got up and said embarrassedly: "Mr. Li, Mr. Sun." ”

Li Tianfeng waved his hand, and then said, "Director Bai, how is the situation?" ”

Bai Lijie said: "At the beginning of the test, you need to wait for a while to know the results. ”

Hearing this, Li Tianfeng personally walked to the instrument, looked at it carefully, and after looking at it, Li Tianfeng was greatly satisfied, the test results fully met the design performance requirements and were fully qualified.

Li Tianfeng said: "Director Bai, take a look." ”

Bai Lijie said happily: "Mr. Li, the performance of this No. 6 sample is qualified. ”

Li Tianfeng said: "Well, fully qualified, Director Bai, immediately carry out the performance test of the next sample." ”

Soon, the next sample of the electronic component is loaded onto the testing instrument, and after the parameters have been adjusted, the inspection work begins immediately.

However, Li Tianfeng quickly frowned, because there was a certain difference between performance and design requirements, that is, it was unqualified.

Bai Lijie also found the problem, and immediately said: "Mr. Li, the performance test of this sample is unqualified, we will replace it with another one." ”

The same model of samples, generally there are two or three pieces, this model of samples, a total of two, there is another one, this one is unqualified, you can replace it with another one, if the other one is qualified, it is easier to say.

Li Tianfeng clicked, and Bai Lijie immediately replaced it with another sample of the same model, and did it himself.

However, the result is still the same, similar to the situation just now, the performance is still unqualified, and the unqualified places are the same, all of them are unqualified for the same parameter.

This batch of electronic components samples is very important, related to the turbofan 20 engine full-featured electronic digital control system can be completely localized, if the domestic really can not manufacture electronic components that meet the performance requirements, it can only be imported from abroad, the localization of the control system will also become a bubble.

Knowing the importance, Bai Lijie said with a solemn face: "Mr. Li, the performance test is unqualified, this is troublesome." ”

Li Tianfeng said: "Show me this unqualified electronic component." ”

Bai Lijie gave this sample of electronic components to Li Tianfeng, Li Tianfeng took this sample, looked at it seriously, and even picked up a magnifying glass to take a closer look, and then personally operated a series of testing instruments and carefully tested it.

Seeing Li Tianfeng's skillful movements, Bai Lijie thought in his heart, Mr. Li is really worthy of the name, and he is so proficient in electronic technology, looking at this, it is very targeted, he should already know where the problem is, and now he is conducting a special test, ready to find out the reason.

In the whole laboratory, it was very quiet, everyone watched Li Tianfeng carry out this series of tests, Sun Xiaoping stood aside, and he secretly admired it in his heart.

After a long time, Li Tianfeng frowned and said to everyone: "The root of the problem cannot be found for the time being, it may be that when they made it, there was a discrepancy between the actual sample and the design drawings." ”

The reason can't be found out for the time being, everyone's heart is also hanging high, Bai Lijie is even more worried, if you can find out the root of the problem, it will be easier to do, make corrections, and make a few more samples, presumably it will be qualified, but now you can't find the reason for the time being, it will be more tricky.

Next, Bai Lijie and several of his subordinates, together with everyone, carried out performance testing on the remaining samples one by one, and the test results were all qualified, which made Li Tianfeng's originally tense heart a little relieved, at least, the performance test of this part of the electronic component samples was preliminarily qualified.

The test is preliminarily qualified, and further performance verification is required, and then a batch can be mass-produced, which can be installed on the engine control system for test verification.

Bai Lijie said: "Mr. Li, this manufacturer of electronic components, the strength is quite strong, these samples, except for the model just now, the rest are all qualified." ”

Li Tianfeng said: "For these electronic components that have just passed the preliminary test, further performance verification and testing will be carried out, and as for the unqualified, I will think about it again." ”

Bai Lijie nodded, and then said: "Mr. Li, we will immediately start further performance verification and testing." ”
