After reading the data, I know that there is a problem in all aspects. Then the next thing is much simpler, the bearing temperature is too high, the most likely there have been problems in two places.

First of all, it is naturally the bearing itself. Due to the accuracy and material, the friction coefficient is caused to cause heat, and the cooling speed of the cooling system is not enough, resulting in a rapid increase in the temperature of the bearing, thereby overheating.

Secondly, the problem of cooling system.

However, their bearings on this engine are not a common bearing on the market, but by Wang Bin, they work out, the precision level can be very high, even higher than the highest level of precision level on the market. It is much higher, reaching the level of classic, after processing, has passed many times, and finally before installing the engine, the engine installation engineer is also the most striking bearings. The harsh examination is reached, and it will be installed on this engine, so it is absolutely impossible to have problems in terms of precision.

As for the material, it is more impossible to have problems. After all, the materials used in this aviation engine bearing are also the high-performance bearing steel materials produced by their Tiangong Technology. According to performance, it can be at a temperature of nearly two thousand degrees. Normal work.

Although it is said that the temperature before the engine is running, the temperature of the turbine will reach two or three degrees, but under the action of the cooling system, the temperature of the bearing at the position is obviously impossible to achieve this extent, and the maximum is one thousand. The temperature of the degree is already very high, it is impossible to more than 2,000 degrees.

It is said that it has emerged here, he judges that there is a problem with the cooling oil circuit system, so he immediately ordered the engine's cooling oil pipeline that the engine has been tried to see if the cooling system appears. What is the problem.

After listening to Professor Poke, the gate of the control room was automatically opened, and the people in the control room also entered the workshop again.

At this time, it may be that Wang Bin's mood is not very good. Professor Wang Bin is comfortable to Wang Bin: "Wang always don't worry, according to my experience, it is determined that this emergence problem is more than 90%. The probability is not the reason why Dafa itself, but the reason why our test is.

Because if it is caused by the cause of the engine itself, it is not necessary to wait until now, there will be a problem when it is just cruising power transfer, after all, the operation time just in the cruise power transfer can reach an hour!

What's more, this engine has also adheredcted three minutes, even if there is a problem in this regard, this engine is also successful.

Because the aircraft is in general, it is impossible to use the stiff force combustion. After all, no matter what kind of engine, if you start the state of burn, if you have an engine or for the aircraft itself The big challenge will greatly shorten the life of the engine and the aircraft itself.

In addition, in general, the aircraft's engine's engine is basically different for too long. It is basically only a few seconds or even a few seconds, even some very good now. Engine, if you stick to the burn, it is impossible for more than 10 minutes. All our engines can last for about three minutes, which is already very good, so actually, Our engine has also been successful.

Of course, if you look at the data we have designed before, this engine is not successful, because our in our design drawings, this engine is at least 15 minutes to more than half an hour. After all, the materials we use are not ordinary materials, but the world's best high temperature high pressure material. "

After listening to the professor of the poker, Wang Bin did not speak, but just nodded. After all, these did not have a professor, he also clear, after this time, he has tonic many space aviation knowledge.

What's more, if you really follow the design data, this is just a level of burn, you have to know that this engine is just a generation of engines, but this engine can not be simple, not only one level of home is burning, but also two Levels and tertiary strengthening combustion status.

According to the design data requirements, in the state of the first-stage bonus, the engine should be considered for fifteen to more than fifteen to more than fifteen to more than fifteen to more than 10, and it must also reach a hundred and thirty kilocker in terms of thrust. Burning, at least five minutes or more, the thrust is at least 15 tens of thousands of cattle, the highest level of three levels of combustion, at least 15 minutes, the thrust is more than one hundred and seventy kilockey .

However, this engine has not been perfect, in addition to the trial platform and other reasons, this engine is still unable to enter the ability of the second or third level to burn, but even if so, actually open the first level. The state of the burning is not in the area for more than three minutes, and it will not work. If it is really the cause of the engine, it is obviously that this engine is still unable to pass.

In the workshop, these route experts and young technicians, Wang Bin, not only in their heart, but silently prayed: "I hope that the cause of the engine itself, otherwise, the trouble is big, many follow-up plans It is necessary to be delayed or even push down. "

At this time, Poke Professor, once again opened to Wang Bin: "Total Wang! We also go to the workshop!"

Wang Bin nodded, and the two came out of this glass control room, entered the workshop, and came to the test desk.

"Old wear, what is wrong?" After coming to the workshop, the professor of poke asked an old manide.

"I have not found any problems in the time, but according to I estimate, it should be a problem with the test.

Because of this simple test desk, it is not a regular test desk, and according to the previous construction, this test desk can withstand the biggest thrust, only 25 tons, if it is in construction, a little error occurs slightly, then the test desk There may be a problem! "

Although they have basically determined the problem of the test desk, they have basically determined that the engine's part, but if anyone dares to exclude the engine part, after all, the problem is not found.

Time passed by a second, soon, I have been in the past ten minutes. When Wang Bin and poke professor, a young technician who is checking the link of the engine and test stop is suddenly The loudly called: "The problem is found, the engine cooling system cooling liquid pipeline screws."

When everyone heard the young technician, everyone put down, and the professor said: "Since the problem is found, then replace the engine to retest, and link in each pipeline There must be no longer gap. "

After listening to the professor, these young technicians immediately found a hydraulic cart dedicated to the lifting engine, and unloaded the engine on the trip to the trip platform, installed new Engine.
