It has entered May, and it has almost been more than a month since the military spring order meeting. Tianfeng Technology's second-generation core machine design is orderly and has completed the design of many parts. It is estimated that in a few months, it will not be a problem.

The trial production of the rq2000 gas turbine engine has basically completed trial production and process verification of each part since the end of last year and now, and only a very small number of parts are still being trial production.

Boeing has made it clear that in late May, Vice President Robbie will lead a team to Tianfeng Technology for business inspections, and things are basically a foregone conclusion.

When contacting and communicating with Boeing, Xu Lilong is basically responsible. Li Tianfeng's work focuses on scientific research, paying attention to the design of his second-generation core engine, trial production of rq2000 gas turbine engine parts, etc.

This gas turbine engine is designed based on the turboshaft e engine. Many parts are similar to the turboshaft e, and some parts are even common. The biggest difference is the combustion chamber part and the accessories part.

Tianfeng Technology Company, Qingshi Manufacturing Base.

In the titanium alloy receiver processing workshop, a receiver is being processed on an imported vertical machining center. This is the accessory receiver of the rq2000 gas turbine engine.

This is a titanium alloy receiver, with a new design, which is very different from the turboshaft e receiver. This is the processing of the third batch of receivers, and the processing enters the last fine boring process. After processing this process, all three-piece receivers will be machined and will enter the final inspection.

For trial production of parts, each batch of generally three or five pieces, and the same is true for this batch of receivers, a total of three pieces.

This is an imported high-precision machining center. The first receiver is boring on the machine tool. Next to the machine tool, in addition to Master Yu who operates the machine tool, there are also Zhang Guangjun, the technical director of the workshop, and Gong Zhao, the supervisor of the craftsman.

Zhang Guangjun is in his thirties and is a senior engineer. As a workshop technical director, he personally stared at the machine tool. It can be seen that the importance of these titanium alloy receivers are.

The processing of the first batch of titanium alloy receivers is basically described as failure. One batch of two receivers is completely scrapped.

The second batch of processing was because of the first processing experience. The processing technology was summarized and improved based on the first processing. The processing condition was slightly better, but it was not qualified.

This is the third batch of processing. Zhang Guangjun knew that the rq2000 gas turbine engine company had won an order of 2,000 units in the military, and the parts trial production has been basically completed. Only a few parts have not yet been tested. His own titanium alloy accessories receiver is one of them.

Through the machine tool safety door glass and looking at the parts being processed on the machine tool, Zhang Guangjun thought in his heart. It must be successful, this time it must be successful.

Last time, I planted it in this process. This process is fine boring two gear installation holes. This is a very important driving gear. The gear installation holes are very high, and the processing of these two installation holes is very difficult.

After more than an hour of processing, Zhang Guangjun was always next to the machine tool. After the processing was completed, the machine tool door opened. Zhang Guangjun took two steps forward and watched Master Yu carefully measure the size. The same was true for the craftsman Zhao, the supervisor, looked at the measurement with a little nervousness.

Master Yu was proficient in movements. He took the inner diameter dial gauge and measured the apertures of the two holes, and said to Zhang Guangjun: "Director Zhang, the aperture is qualified."

Zhang Guangjun felt relieved when he heard that the aperture was qualified, but his heart was far from falling. Anyone with processing experience knew that passing the measurement on the machine tool does not mean that the parts were taken off the machine tool to measure it.

Zhang Guangjun nodded and said, "Master Yu, remove the parts."

Operator Master Yu took off the parts as he said, and measured them again in the free state of the parts, and the parts were still qualified.

Passed again.

Zhang Guangjun was relieved, and Gong Zhao was obviously happy. He passed the measurements twice, so there should be no major problems.

However, these two gear installation holes not only have dimension requirements, but also have different axial and verticality requirements, and both are very strict. Whether it is coaxial or verticality, they are required to be within two wires.

Zhang Guangjun said: "Let's go, let's go to the three-coordinate measurement and measure the technical requirements of these two holes."

After saying that, Zhang Guangjun even picked up the part himself. The titanium alloy attachment receiver is not big and light, so it is not difficult to pick it up.

Zhang Guangjun, the technical director, came to measure the parts personally, so naturally there was no need to queue up. The measurement started immediately. After a few minutes, the measurement results came out.

The two gear mounting holes have a coaxial degree of 8000 and a slight verticality, which is completely within the middle difference, indicating that the processing is very good.

Looking at the measurement sheet, Zhang Guangjun said: "Mr. Zhao, we have finally passed the processing!"

Mr. Zhao, the chief craftsman, recalled the hardships in the trial production and processing of this titanium alloy receiver, and couldn't help but feel relieved and said with emotion: "Director Zhang, we have finally succeeded!"

………

In the office.

Li Tianfeng was listening to the report of Zhang Can and Zeng Qinghai. One of them was the general manager of Qingshi Manufacturing Base and the other was the chief craftsman of Tianfeng Technology Company. The trial production of the rq2000 gas turbine was basically the responsibility of the two.

Zhang Canhui reported: "Boss, our rq2000 gas turbine engine has entered trial production since the end of last year. Until now, all parts have been fully trial production and process verification."

Zeng Qinghai also said: "Boss, we have completed the trial production and process verification of parts, and we can start the assembly of the first engine immediately. I checked and tried to produce qualified parts, enough to install two engines."

Li Tianfeng was very happy that he completed the trial production in May and then he could enter the assembly of the first rq2000 gas turbine engine, and then he would enter the test drive verification and then start mass production.

Because it is a ground gas turbine engine, the test drive verification of the rq2000 engine is far less troublesome than the aircraft engine. The test drive verification will not take a long time, and it will not take several months like the aircraft engine.

If it goes well, one month will be enough. Within one month, the test drive verification of the rq2000 gas turbine engine can be completed.

Li Tianfeng said: "Our rq2000 gas turbine has finally completed a comprehensive trial production. In this way, the first engine assembly will begin immediately. In the second half of the year, we will deliver the engine in batches."

Li Tianfeng's decision was quickly implemented.

The assembly workshop of Qingshi Manufacturing Base immediately began the assembly of the first rq2000 engine. In just a few days, the assembly of the first engine was completed.

Everyone can finally see the true face of the rq2000 engine. In the past, they were all in the form of pictures. Now, they can take a closer look at this engine.

The rq2000 engine looks a little similar to the turboshaft e engine, but it is also very different. After all, it is a ground-based gas turbine engine.

As a ground-based gas turbine engine, the work-to-weight ratio is not the first priority, so the work-to-weight ratio of the rq2000 engine is only about 8, which means it is heavier than the turboshaft e engine.

However, the rq2000 engine is more fuel-efficient because it uses very advanced combustion chamber technology and has a very high fuel utilization rate. With a power of 2,000 horsepower, the fuel consumption per 100 kilometers is only 280 liters.

The first rq2000 gas turbine engine was assembled, and of course Li Tianfeng came here in person. Seeing this engine, Li Tianfeng looked happy.

Li Tianfeng looked at it carefully and was very satisfied with the quality of this engine. Although it was the first engine, the parts used were basically all qualified parts, and the assembly quality was very good. Li Tianfeng looked at the assembly records.

Li Tianfeng said: "Mr. Zhang, the engine is good!"

Zhang Can looked happy and felt very accomplished. She was praised by Li Tianfen, and Zhang Can was even more happy.

Li Tianfeng said: "Start tomorrow, we will conduct the first test drive of the engine!"

Zhang Can nodded quickly.

………

The test run of the rq2000 gas turbine engine was very smooth and there were basically no problems. Now, a series of test runs are being carried out according to the requirements of the test run technical outline.

Shortly after the engine entered the test run, Ma Delong and his party came to Tianfeng Technology Company. Ma Delong came here to place an order.

Ma Delong and his party came that day and returned to Donghai in the afternoon that day, showing very high efficiency and only stayed at Tianfeng Technology Company for a few hours.

Within a few hours, the two parties completed more than 20 billion orders, and COMAC once again ordered 200 turbofan 16 engines and 300 turbofan 17 engines of Tianfeng Technology.

With 500 engines and more than 20 billion orders, Li Tianfeng found that he liked Madelong more and more. This was simply his God of Wealth!

Last month, Tianfeng Technology Company and the military signed an order of 43 billion yuan, and this time it signed an order of more than 20 billion yuan with COMAC, plus more than 10 billion yuan with Airbus at the beginning of the year, as well as possible orders with Boeing in the future.

This is simply a lot of money!

Li Tianfeng even thought in his heart whether he will be lucky this year. If this continues, he will definitely achieve the goal of 100 billion yuan in output value this year.

Brazil Amazon, Embraer, and Bombardier have not signed a contract with themselves this year, if these orders are added.

Let me do it.

Li Tianfeng thought about it in his mind, and he was shocked by this calculation. He was really rich!

Li Tianfeng thought to himself, with such a development trend and such a good momentum, it seems that he has to take a bigger step. What engine should he launch in the next step? Or should he start preparing to enter the aircraft manufacturing industry?
