Returning to the second institute with Director Bai again, not to mention the rest, Yang Hui first came to the test center with Director Bai, and now the test center of the second institute is definitely in full swing.

Not only because there is a turbofan 10 ground test work here, so there are a large number of technical personnel, more and more national military standard revision team personnel stationed, they have to follow up the development of the turbofan 10 throughout the process, according to the development experience of the turbofan 10, the new national military standard will be gradually revised and improved.

In the development of turbofan 10, various technical papers continue to emerge, and even the international has caused huge repercussions, the reason is naturally the design of the fatigue tolerance of the first opening of the turbofan 10. Although the prospect of this thing is good in '85, there is really no engine manufacturer who has the courage to use it at this time, after all, it is a bit too risky.

As soon as Yang Hui and Director Bai arrived at the test center, Chief Designer Wen of Turbofan 10 came up with phased results.

"This is the current design of our turbofan 10, and we put a lot of engines into tests, dismantling them all into parts every 100 hours of operation, and checking fatigue one by one. At the 380th hour, there was extensive fatigue damage to the compressor blades, and then we improved the process, and now the entire engine has been running for 510 hours without failure, and the first rebuild life is expected to be around 630 to 650. ”

Hearing this, Yang Hui can only say that it is really not easy, under the limitation of materials and processes, through the use of damage tolerance design ideas, the first translation period has been nearly doubled, which has to be said to be this huge progress.

The progress is obvious, but Yang Hui's visit this time is not to inspect the work, he is here to ask for help, to exhibit the engine at the air show, it is necessary to coordinate an engine from the test center.

Wait until Director Bai and Chief Wen have finished exchanging the development of the engine. This is what Yang Hui needs to put forward.

"That...... Master Wen! This time I came mainly to ask for your help, which is mainly related to our turbofan 10 engine, so I can only look for you now. ”

Looking for yourself? It also has something to do with the turbofan 10, Wen always looked at the youngest and most capable leader of the base, and knew that he really couldn't refuse this time.

stood up and looked like everything was easy to discuss: "Let's say, if you want to say that the current turbofan 10 can have today." You Secretary-General Yang has also made a lot of contributions, and these three major improvement plans are all proposed by you, and we will be satisfied with anything. ”

Master Wen is easy to speak, so Yang Hui will not be verbose, and directly pick out the meaning.

"This time it's mainly because we are participating in the air show, and we need some good things to come to the town to participate in the Paris air show, so this time we are going to bring the engine to the exhibition."

The engine exhibited at the exhibition, which was Yang Hui's plan, and said it to Mr. Wen. Chief Wen has no opinion, how can this kind of good opportunity to give the new engine a long face, how can it be missed.

In the future, if I said that I could be considered a little well-known as the chief teacher, I immediately agreed.

"No problem, isn't it just the engine? We strongly support it, just say what we need, this is the first domestic engine to participate in the air show, we must strongly support. ”

Let's walk into the test center. Yang Hui pointed to the engine that was put aside and said clearly.

"I don't need much. First of all, the engine, you need a complete engine, of course you don't need an engine that is being put into testing, we can repair it with a scrapped engine. ”

Anyway, it's just for exhibitions, and you don't need to start it, you just need to take out the real thing and put it there. As for the old and the new, it's really not a big requirement.

The scrapped engine test center can still find out, and it doesn't cost a lot of money to refurbish it, and even a few engine parts can be combined to save an iron guy who can barely work for a few hours.

Pat the scrapped engine at your feet. Thinking that these scrapped products could still have a chance to exert their residual heat, Mr. Wen agreed.

"No problem at all, the day after tomorrow we can come up with an engine that is enough for the exhibition, to ensure that the structure of all components is intact and free of defects."

The main engine is solved, and the rest is not a problem at all.

"That's the best, in addition, we also need some data, don't need to be too detailed, write out the main parameters, and just pick up the secondary data and write it on it."

This is a science, an engine will definitely not be perfect, but when exhibiting at the exhibition, we should pay attention to it, don't write out the data that is not good-looking, it is enough to write out the good-looking data, even if it is a big deal in the end, I forgot it.

Chief Wen didn't know this at first, but when Yang Hui said it, he instantly understood, and he had to admire this guy for being cunning enough, but it was a good thing for the base.

Don't say much, nod and turn around to find someone to do something, don't worry about the rest at all, Yang Hui will deal with it.

……

In terms of communication, the other J-74 models are proportional to these, because of the experience in making the J-7A model, it is naturally quite handy.

However, the coordination of the Jianjiao 7A performance aircraft is more troublesome, and it is not easy to transfer the plane from Pakistan to Paris or through other means.

Nowadays, the field maintenance work of the Jianjiao-7A is also not simple, and it is a big problem to ensure the maintenance work of the Jianjiao-7A in a completely unfamiliar place, so that the aircraft can take off and perform as scheduled.

It can even be said that it can ensure the flight and combat of fighters in the field, which is really not possible for few countries, and this can completely reflect the overall strength of a country's air force.

Not all countries can be like when Maozi participated in the Paris Air Show, when the SU-27 was struck by lightning, flew back for maintenance, and took off as usual the next day.

These require Yang Hui to coordinate many aspects, running around, looking for relationships everywhere, looking for skilled ground staff, and even the Bayi team has visited.

It took more than ten days to go back and forth in this, and it was barely possible to pull out a decent air show ground support team. It is also the first time in the republic, after all, there is no precedent to learn from.

Ready, finally ready to set off: "Don't worry, this time to participate in the air show, you will definitely be able to create another brilliant scene, a blockbuster, and strive to win a few large orders." ”

With a small team of six exhibitors, the plane took off and flew directly to Paris, and there were five days before the opening of the air show.

Until the opening day of the air show, the Le Bourget air show was once again crowded, although the air show opens every year, but aircraft manufacturers, civil aviation companies, and even the military of various countries, as well as aviation fans from all over the world are still happy to participate in the air show one after another.

The Paris Air Show in '85 was still in anticipation of everyone's opening, and what remained unchanged was that several old European performance teams were still flying their subsonic trainers, doing everything they could to fly beyond their so-called limits, in order to win the applause of the audience.

But it can't always be like this every time, every air show must have some new ideas, and the novelty of the 85th year is naturally the Jianjiao-7A fighter trainer brought by Yang Hui this time.

In the flow chart of the air show, everyone already knows that a new aircraft will fly to the air show this time, but what kind of aircraft is it, the air show official also sold it once, and did not release the specific model and picture.

At the same time, while the Red Arrows performance team over Le Bourget Airport was still performing hard, the F/T-7A (NATO number) in the hangar officially arranged by the Le Urget Air Show had been prepared.

The red and green livery is still the same as the livery of the Sea Harrier in the sea off Pakistan half a year ago, wearing a military uniform that returned from the battlefield, and the pilot was also Zhang Tao, who was piloting Jianjiao 7A at that time.

Get into the cockpit and get ready for take-off. Speaking in unskilled English.

"Tower, tower, here is the third batch of take-off show aircraft F/T-7A, which is about to perform a single-plane flight show, ready to take off." (To be continued......)
