The time has entered May, the military spring order meeting has been almost a month past, the second-generation core machine design of Tianfeng Technology Company, in an orderly manner, has completed the design of many parts, it is estimated that in a few months, the design will be fully completed, not a problem.

The trial production of RQ2000 gas turbine engine began at the end of last year, and by now, the trial production and process verification of various parts have been basically completed, and only a very small number of parts are still in trial production.

Boeing has made it clear that in late May, Vice President Robbie will lead a team to Tianfeng Technology Company for a business inspection, and the matter is basically a certainty.

In contact and communication with Boeing, Xu Lilong is basically in charge, and Li Tianfeng's work focuses on scientific research, focusing on the design of his second-generation core engine, the trial production of RQ2000 gas turbine engine parts, and so on.

This gas turbine engine is designed on the basis of the turboshaft E engine, many parts are similar to the turboshaft E, and even some parts are common, the biggest difference is the combustion chamber part, and the accessory part.

Tianfeng Technology Co., Ltd., Qingshi manufacturing base.

In the titanium alloy casing processing workshop, on an imported vertical machining center, a casing is being processed, which is the accessory casing of the RQ2000 gas turbine engine.

This is a titanium alloy casing, a new design, and the scrollshaft E casing is very different, this is not, this is the third batch of casing processing, and the processing into the last fine boring process, after the processing of this process, this batch of three casings. After all the machining is completed, it will enter the final inspection.

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

This is an imported high-precision machining center, the first casing is boring on the machine tool, next to the machine tool, in addition to the operation of the machine tool Master Yu, as well as the technical director of the workshop Zhang Guangjun, and the chief technician Zhao Gong.

Zhang Guangjun is in his thirties. Senior engineers. As a workshop technical director, I personally stared at the machine tool, which shows the importance of this batch of titanium alloy casings.

Processing of the first batch of titanium casings. Basically, it is described as a failure, a batch of two receivers, all scrapped.

The processing of the second batch, because of the first processing experience. And on the basis of the first processing, the processing technology was summarized and improved. The processing situation is slightly better, but it is not yet qualified.

This is the third batch of processing, Zhang Guangjun knows that RQ2000 gas turbine engine company has won the order of 2000 units of the military, and the trial production of parts has been basically completed, only a few parts have not been completed for the time being, and their own titanium alloy attachment casing is one of them.

Look through the glass of the safety door of the machine and look at the parts being machined on the machine. Zhang Guangjun thought in his heart, he must succeed. This time it must be successful.

Last time, it was planted in this process, and this process was fine boring two gear mounting holes, which is a very important driving gear, and the gear mounting hole requirements are very high, and the processing of these two mounting holes is very difficult.

After more than an hour of processing, Zhang Guangjun has been next to the machine tool, after the processing, as soon as the machine tool door opened, Zhang Guangjun took two steps forward, carefully watched Master Yu for dimensional measurement, and the chief technician Zhao Gong was the same, slightly nervous looking at the measurement.

Master Yu acted skillfully, took the inner diameter dial gauge, measured the aperture of these two holes, and said to Zhang Guangjun: "Director Zhang, the aperture is qualified." ”

Hearing that the aperture is qualified, Zhang Guangjun is slightly relieved, but a heart is far from the ground, people with processing experience know that the measurement on the machine tool is qualified, which does not mean that the parts are taken down from the machine tool to measure and qualified.

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

The operator Yu removed the parts according to his words, and measured them again in the free state of the parts, and the parts were still qualified.

Qualified again.

Zhang Guangjun was slightly relieved, and Zhao Gong was obviously happy, both times the measurement was qualified, and there should be no major problem.

However, these two gear mounting holes not only have size requirements, but also different axial and verticality requirements, and they are very strict, whether it is coaxiality 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 this part in person, the titanium alloy attachment case is not large, it is very light, and it does not take much effort to pick it up.

Zhang Guangjun, the technical director, personally took the parts to measure, naturally there was no need to queue, the measurement started immediately, and after a few minutes, the measurement results came out.

Two gear mounting holes, eight thousandths of the coaxiality, one trace of verticality, completely within the middle difference, indicating that the processing is very good.

Looking at the metering sheet, Zhang Guangjun said: "Zhao Gong, we are finally qualified!" ”

Zhao Gong, the technician in charge, recalled all the hardships in the trial production and processing process of this titanium alloy casing, and couldn't help but feel light, and said with emotion: "Director Zhang, we have finally succeeded!" ”

………

In the office.

Li Tianfeng is listening to the reports of Zhang Can and Zeng Qinghai, one of them is the general manager of Qingshi manufacturing base, and the other is the chief technologist of Tianfeng Technology Company, and the trial production of RQ2000 gas turbine is basically responsible for the two of them.

Zhang Can reported: "Boss, our RQ2000 gas turbine engine has entered trial production since the end of last year, and up to now, all parts have been fully completed trial production and process verification. ”

Zeng Qinghai also said: "Boss, we have fully completed the trial production and process verification of parts, and we can start the final assembly of the first engine immediately. ”

Li Tianfeng is very happy that the trial production will be completed in May, and then the final assembly of the first RQ2000 gas turbine engine will be entered, and then the test run will be verified, and then mass production will begin.

Because it is a ground gas turbine engine, the test verification of the RQ2000 engine is far less troublesome than that of the aero engine, and the test verification will not take a long time, and it will not take several months like the aero engine.

If it goes well, one month is enough, and within one month, the test verification of the RQ2000 gas turbine engine can be fully completed.

Li Tianfeng said: "Our RQ2000 gas turbine has finally completed a comprehensive trial production, so that the final assembly of the first engine will begin immediately, and 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, and the assembly of the first engine was completed in just a few days.

Everyone can finally see the true face of the RQ2000 engine, in the past, it was in the form of pictures, now, you can take a closer look at this engine.

The RQ2000 engine looks a little similar to the turboshaft E engine, but it is very different, this is a ground gas turbine engine after all.

As a ground gas turbine engine, the power-to-weight ratio is not the first, so the power-to-weight ratio of the RQ2000 engine is only about 8, that is, it is heavier than the turboshaft E engine.

However, the RQ2000 engine is more fuel-efficient, because it adopts very advanced combustion chamber technology, the fuel utilization rate is very high, and the fuel consumption of 2000 horsepower is only 280 liters per 100 kilometers.

The final assembly of the first RQ2000 gas turbine engine was completed, and Li Tianfeng came over in person, and Li Tianfeng was happy to see this engine.

Li Tianfeng took a serious look at it, and was very satisfied with the quality of this engine, although it was the first engine, but the parts used were basically all qualified parts, and the assembly quality was very good, Li Tianfeng looked at the assembly record.

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

Zhang Can's face was happy, he had a great sense of achievement, and he was praised by Li Tianfen, and Zhang Can was even more happy.

Li Tianfeng said: "Starting tomorrow, the first test run of the engine will be carried out!" ”

Zhang Can nodded hurriedly.

………

The RQ2000 gas turbine engine test went very smoothly and there were basically no problems, and now, a series of test runs are being carried out in accordance with the requirements of the test technical outline.

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

Ma Delong and his entourage, who came that day, returned to the East China Sea in the afternoon of the same day, reflecting very high efficiency, and only stayed in Tianfeng Technology Company for a few hours.

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

With 500 engines and more than 20 billion orders, Li Tianfeng found that he liked Maderon more and more, which is simply his God of Wealth!

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

It's a lot of money!

Li Tianfeng even wondered if he was lucky this year, and if he continued like this, he would definitely be able to achieve the goal of 100 billion output value this year.

Brazil's Amazonas, Embraer, and Bombardier have not signed orders with themselves this year, if you add these orders.

Let me do the math.

Li Tianfeng calculated it in his heart, and he was taken aback by this calculation, it was really a lot of money!

Li Tianfeng thought in his heart, such a development trend, such a good momentum, it seems that his pace is going to be a little bigger, what engine will he put on the next step? Or do you want to start preparing for a career in the aircraft industry?
