"Well, Mr. Wang, hurry up and send technicians to bring relevant equipment to determine the engine condition and maintenance as soon as possible. If the condition is not serious, we can continue the next flight test work," Qiu Tuan said.
"OK! Qiu Tuan, I''ll bring technicians and equipment right away!" Wang Bin returned to the road for the first time after listening to Qiu Tuan''s words.
After all, it is also very important for Tiangong technology to repair the engine early, so that the test flight of the No. 9 aircraft under test can be completed as soon as possible, so as to lay a good foundation for larger-scale or even comprehensive transformation of the engine of the No. 9 aircraft in China in the future.
At the same time, for the situation of the engine after being hit by birds, in fact, Wang Bin and them are also very related. After all, this is related to the safety of Wang Bin''s engine.
Because Wang Bin had already calculated when they designed the engine before Tiangong technology. Under normal circumstances, even if the engine is involved in birds, even large birds such as big white geese will not have any substantive impact on the engine.
However, the No. 9 aircraft collided with birds during landing, but the engine was damaged. Although according to Qiu Tuan, such damage is actually very slight and will not have much impact on the overall performance of the engine. If the aircraft is not a test aircraft, such damage does not need to replace the engine at all.
However, this is unacceptable for Wang Bin, because such a situation has been greatly inconsistent with the data in the previous design and test run, so they must conduct a new inspection on the engine, retain the data and make new adjustments to the engine, so that when the engine encounters such a situation in the future, It won''t happen like this.
After the two talked about it on the phone, Wang Bin immediately informed the person in charge of the engine, that is, Professor Zhang. Then Professor Zhang arranged two technicians with the highest technology in the engine laboratory. The four immediately called Lubo, got on a No. 9 plane that was supposed to be transformed, and flew to which Plateau Airport.
After several hours of flight, Wang Bin and his team finally arrived at the Plateau Airport. After Wang Bin and his team got off the plane, they immediately carried out a series of inspections on the plane.
"Mr. Wang, you''re here. To tell the truth, up to now, we still can''t believe that this plane will still be in such good condition after being hit by birds. Let alone the engine, the condition of the aircraft fuselage is better than we expected, especially after the transformation of your Tiangong technology After hitting, there was no damage at all.
On the contrary, there are some damages in the areas that have not been modified but should be the least impacted, such as the tail of the aircraft.
The situation of the engine made everyone in our airport can''t believe it at that time. After such a situation, the engine can still operate normally and reduce the safety of the aircraft. Moreover, no damage was found after driving.
After careful inspection, we found that there were several places on several fan blades that were different from other blades. We really thought that this engine had been hit by birds, and it was still a medium and large bird. "After seeing Wang Bin, Qiu Tuan immediately came up and said.
"Qiu Tuan! It''s really unexpected, but it''s not that the engine is in some good condition. On the contrary, in the design time of this engine and the data during the previous test run, it''s reasonable that even if it was hit by medium and large birds, the interior of this engine should not be damaged.
But the current situation is that the fan blade of this engine is actually damaged, which is definitely caused by our negligence in design or other reasons. Of course, we can''t be sure until we check this engine. "
After listening to Wang Bin''s sharing, Qiu Tuan was even more shocked. He really didn''t expect that Wang Bin and Tiangong technology''s engine were not satisfied after they achieved such a degree. They also wanted to be intact after such a situation.
"By the way, Mr. Wang! Since you want to conduct a comprehensive inspection of this engine, do you want to dismantle the engine on the No. 9 aircraft? If you want to dismantle it, I will immediately arrange ground service technicians to dismantle it." Qiu Tuan said.
"No, we have considered a variety of situations when designing this engine, including maintenance such as checking and replacing blades, so we can check and replace blades without dismantling the engine from the aircraft." Wang Bin said.
When Wang Bin finished, Professor Zhang and the technicians he brought had opened the engine casing and began to inspect the engine.
After all, even if it is known that the fan blades of the engine are damaged at this time, they still need to query what causes the fan blades of the engine to be damaged, because according to the design and test data, if only birds hit or get involved in the engine, it is not enough to cause damage to the engine, even slight.
Because the glass hardness of the engine and the sharpness of the edge of the fan blade are absolutely enough to turn any bird involved in the engine into foam.
So they are sure that the damage to the engine blades is not only caused by these birds, but also likely caused by other reasons.
Professor Zhang and the technicians of Tiangong technology are professionals and have professional testing equipment for this engine, so the test results came out soon.
The internal condition of this engine is very good, especially the core machine of the engine. There are no problems. Even the turbine blades of the engine are not the same as the fan blades. Only a few fan blades are damaged.
At the same time, during the inspection, we have preliminarily judged the reason why the fan blade was damaged.
And it is also consistent with Wang Bin''s previous judgment. The damage to the fan blade is not only caused by the impact of birds, but actually caused by other reasons. In other words, when designing this engine, there was no comprehensive consideration.
In fact, the main reason for the damage of the fan blade of the aircraft engine caused by the bird impact was not the bird itself, but some small stones whose hardness was much higher than that of the bird itself, because when they inspected the engine, they found a large number of crushed stones inside the engine.
