Chapter 326 Test Flight of High Thrust Turbofan Engine

It is precisely because the 929 is still under development at this time, so in fact, Wang Bin and his team’s test flight of this engine is only the military’s large transport aircraft.

But in fact, there are not many models available for the military at this time. In addition to the No. 20 transport aircraft that China has just developed by itself, it also comes from the 76 large-scale military and civilian transport aircraft from the Arctic. As for the transformation of imported civil aviation For the large passenger plane, Wang Bin still had no such plan in his heart at this time.

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

Thinking of this, Wang Bin didn’t think about it anymore. After all, it was no longer his choice, but it depends on which aircraft the military wants to use as a test flight target. However, Wang Bin still has a certain premonition in his heart. Fang is likely to use China’s own No. 20 transport aircraft as the target of the flight test.

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

However, in a few days, just as Wang Bin was a little anxious, the test machine Wang Bin was looking forward to finally came, and this time this aircraft is going to be installed with Tiangong Technology’s s003 turbofan engine. It is not the No. 76 transport aircraft that Wang Bin thought before, but the No. 20 transport aircraft that is completely made in China.

This made Wang Bin very surprised. After all, even the Chinese military itself does not have a lot of this aircraft. Even if it is not enough for its own use, it will actually allocate one for the test flight of their Tiangong Technology s003 turbofan engine. .

“Qiu Tuan! Unexpectedly that you are really willing to use the 20th plane for a test flight, are you worried about any accidents?” When getting off the plane, Wang Bin said to Qiu Tuan very unexpectedly.

“Mr. Wang! Originally, we were also planning to use the 76th aircraft for the verification test flight, but considering that the 76th aircraft is not a domestically-produced aircraft, and its design life has been a little longer, the most important thing is for the many core data of the aircraft. We also don’t fully understand it, so the risk is still very high if the No. 76 transport aircraft is used for the verification test flight.

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

The most important thing is that, although our No. 20 aircraft has entered the mass production stage, and the domestically-made 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 turbofan engines are imported from abroad, it is still far from enough.

Also, whether it is our own small-scale mass-produced turbofan engines or engines imported from Arctic countries, there are some problems. After all, people don’t sell their most advanced engines to Wang Bin. At the same time, in terms of price, it is even more outrageous.

That’s why we simply use this aircraft as the test flight for this test flight verification. As long as your Tiangong Technology’s engine can be successfully tested and the data meets your expected requirements, this will greatly reduce our aircraft. The pressure on the engine.

At that time, the production capacity of this aircraft will be greatly Ascension, it is with these considerations that we will use this aircraft for test flights.

At the same time, in order to ensure the condition of the aircraft during installation and test flight, we also specially invited the manufacturer of this aircraft to send a number of technology personnel to cooperate with you to install the engine. “Qiu Tuan said.

With the arrival of the 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, because the aircraft originally installed a large thrust The bypass is more powerful than the turbofan engine, and the strength of the engine pylon and the wing is also sufficient. Therefore, for this aircraft, it is not necessary to install the tg-s002 on the 9th aircraft. Improve.

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

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

After completing the installation of these engines, the technical personnel brought by Wang Wangbin and Qiu regiment conducted a comprehensive inspection of the aircraft, and after confirming 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 quickly noticed. After all, there are many people who pay attention to this aircraft, even though it has been several years since the aircraft came out. But there are still many people paying attention to this aircraft.

So, for a while, the No. 20 plane that was flying in a test flight appeared on the entire network.

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

“Oh my God! What I found out, the No. 20 transport aircraft actually changed the engine again, and the diameter of this turbofan engine seems to be much larger than before, and at the same time, the sound made by this engine during flight , Also seems to be smaller, I don’t know how this engine performs.”

“Yes! But for the manufacturer of this engine, I still know a little bit. After all, the engine hood of this engine obviously has the words and trademarks of Tiangong Technology, so it is obvious that this engine must be Tiangong Technology. Type product.”

“No! This engine is really a product of Tiangong Technology. I just went to the official website of Tiangong Technology to take a look and found that this is really an engine developed by Tiangong Technology, and some of this engine basic data.”

“Yes! I have seen it too. According to the data of Tiangong Technology, the model of this engine is tg-s003 turbofan engine, and the life of this engine is very long, and the first repair time can reach at least 15,000. More than hours, 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 a staggering 30 tons or more. Although the official website does not publish the specific data of this engine, it can be inferred based on the published data of more than 30 tons. The thrust of the engine is at least 31 to 32 tons.

If these are true, then as Tiangong Technology itself said, the performance of this engine has definitely reached the level of the world’s top engine. ”
