It is precisely because the 929 is still under development at this time that the test flight targets of Wang Bin and his team are actually the large military transport aircraft.

But in fact, there are not many models available for the military to choose from at this time. In addition to the No. 20 transport aircraft that China has only developed recently, it is also the 76 large military-civilian dual-purpose transport aircraft from the Arctic. As for the transformation of imported large civil aviation passenger aircraft, Wang Bin still had no such plan at this time.

In other words, there are actually only two test flight subjects available for Wang Bin to choose.

Thinking of this, Wang Bin no longer thought about it. After all, this is no longer something he can choose, but it depends on the military that the aircraft is used as the test flight target. However, Wang Bin still had a certain premonition in his heart that the military is likely to use the No. 20 transport aircraft produced by China itself as the test flight target.

But then Wang Bin felt it was impossible. After all, the quantity produced by the No. 20 transport aircraft is still very preferred, so it is impossible to install the s003 turbofan engine for verification and test flights. Therefore, the final test flight target is the No. 76 aircraft from the Arctic Kingdom.

However, a few days later, just when Wang Bin was waiting a little anxiously, the test aircraft that Wang Bin was looking forward to finally arrived. This time, the aircraft that was preparing to install the s003 turbofan engine of Tiangong Technology was not the No. 76 transport aircraft that Wang Bin thought before, but the No. 20 transport aircraft that was completely domestically produced.

This surprised Wang Bin. After all, even the Chinese military does not have many of this aircraft, and even if it is used by itself, it will actually split one to carry out the test flight of their Tiangong Technology's S003 turbofan engine.

"Qiu Tuan! I didn't expect that you would really be willing to use the No. 20 plane for test flights. Are you worried about any accidents?" When the plane stopped at the airport runway today, when Qiu Tuan, the crew and several technicians got off the plane, Wang Bin said to Qiu Tuan very unexpectedly.

"Mr. Wang! We were originally planning to use the No. 76 aircraft for verification and test flights, but considering that the No. 76 aircraft is not a domestic aircraft and its design years have been a bit long. The most important thing is that we do not fully understand the many core data of the aircraft, so if we use the No. 76 transport aircraft for verification and test flights, the risk is still very high.

But this No. 20 transport aircraft is different. Since this aircraft is completely designed and manufactured by ourselves, we all know all the data and performance of this aircraft. Therefore, compared to using No. 76 transport aircraft for verification and test flights, the risk of using No. 20 aircraft is much smaller.

The most important thing is that although our No. 20 aircraft has entered the mass production stage, and the domestic large bypass ratio turbofan engine specially built for this aircraft has also entered the small-scale mass production stage.

However, its production capacity is still very limited, which greatly restricts the production speed of this aircraft. Even if some large-thrust large-bypass ratio turbofan engines are imported from abroad, it is still far from enough.

Also, whether we have entered a small-scale mass-produced turbofan engine or an engine imported from the Arctic, there are some problems. After all, they don’t know how to sell our most advanced engine to Wang Bin, and at the same time, it is even more outrageous in terms of price.

That's why we simply use this aircraft as the test flight test target for this test flight verification. As long as the engine of Tiangong Technology can successfully test flight and the data meets your expected requirements, this will greatly reduce the pressure on our aircraft in terms of engines.

By then, the production capacity of this aircraft will be greatly improved. It is precisely because of these that we will use this aircraft for test flights.

At the same time, in order to ensure the status of the aircraft during installation and test flight, we also specially invited the manufacturer of this aircraft to send several technicians to cooperate with you to install the engine." Qiu Tuan said.

With the arrival of this No. 20 transport aircraft, Wang Bin and others naturally began to disassemble the original engine for the aircraft and install a new engine. At the same time, since the aircraft was originally equipped with a large thrust large bypass ratio turbofan engine, and the strength of the engine mount and wings was sufficient, this aircraft does not need to be used like the tg-s002 model installed on the No. 9 aircraft before. The aircraft itself must be improved first.

Moreover, since this aircraft is currently the latest transport aircraft independently developed by China, even if Wang Bin and his Tiangong Technology want to have any ideas about this aircraft, the military will definitely not allow it.

It was just at least a simple engine replacement. It took only three days before Wang Bin and the others completed the replacement project of the four engines of the aircraft.

After installing these engines, the technicians brought by Wang Wangbin and Qiu Tuan conducted a comprehensive inspection of the aircraft and confirmed that there were no problems, they began to test the aircraft.

As the test flight of this aircraft began, the engine of this aircraft was naturally noticed quickly. After all, there are many people paying attention to this aircraft. Although this aircraft has been out for several years, many people are still paying attention to this aircraft.

So, for a moment, this No. 20 aircraft that was being tested appeared on the entire network.

At the same time, many online news media and even official news have reported this incident one after another.

"Oh my God! What did I find? The No. 20 transport aircraft has actually replaced the engine, and the diameter of this turbofan engine seems to be much larger than before. At the same time, when flying, the sound made by this engine seems to be smaller, so I don't know how the performance of this engine is."

"Yes! But I still know something about the manufacturer of this engine. After all, the engine hood obviously has the words and trademarks of Tiangong Technology, so it is obvious that this engine must be a product of Tiangong Technology."

"No! This engine is really a product of Tiangong Technology. I just went to Tiangong Technology's official website and found that it is really an engine developed by Tiangong Technology, and some basic data of this engine."

"Yes! I also saw that according to data from Tiangong Technology, the model of this engine is a tg-s003 turbofan engine, and the life of this engine is very long. The first repair time can reach at least 15,000 hours, and the full life of the engine can reach at least 45,000 hours.

At the same time, the thrust of this engine is also very large, reaching an astonishing thirty tons. Although the specific data of this engine is not published on the official website, based on the published data of more than thirty tons, it can be inferred that the thrust of this engine is at least 31 to 32 tons.
