While Wang Bin was chatting with Master Qiu, Professor Poke and others had already stepped forward to check the condition of the engine.
Although according to previous inspections by Master Qiu and the manufacturer, it was not the engine that added points to the aircraft, but Wang Bin and the others had to personally inspect it before they could rest assured.
At the same time, they also want to see how the engine is damaged after such a major accident, and if possible, they will also improve the engine specifically for such accidents to make it In the future, this is the kind of thing that will happen in the future, and the engine can also maintain a certain amount of power.
For example, with intelligent design, if the engine fails to restart several times, the engine will automatically switch to the electric drive mode. In this way, such accidents can be effectively avoided.
At the same time, they also want to know what is wrong with the aircraft, whether it is a component problem in the fuel system, or a design flaw in the process of improving the design of the aircraft.
After chatting with Master Qiu for a while, Wang Bin also came forward and worked with Professor Poke and others to find the cause of the accident.
In fact, due to the crash of the plane, the whole plane has fallen into disarray at this time, the fuselage has been sectioned into several sections, the main wing has been completely broken, and the entire nose has disappeared. It is obvious that the plane is in When it crashed, the nose landed first, then the fuselage.
Fortunately, the engine is installed on the fuselage. It has been strengthened and improved to maintain a relatively intact state. This zero inspection is relatively easier. Otherwise, if the aircraft is completely damaged, if you want to find the problem, just Difficult.
After Wang Bin and others came to the wreckage of the aircraft, they first worked with Professor Poke and others to find out the engine data recorder in the aircraft engine. After all, because this engine is a new type of engine, Tiangong Technology For better data collection and future improvements, this engine is equipped with a data logger.
Subsequently, Wang Bin, Professor Piao and others found out the data recorders in the two engines, and immediately used the equipment to view their data.
Of course, when Wang Bin was checking the engine’s data, Qiu and the military personnel all saw Wang Bin’s actions, and they all gathered around to check the data with Wang Bin and others.
After all, they didn’t know before that there was an independent data logger on this engine.
According to the data, just before the shutdown of the aircraft engine, the fuel supply of the engine has fluctuated many times, and the oil pressure of the fuel supply pipeline to the engine has also changed many times, and finally the oil pressure drops sharply until the fuel supply is cut off. .
Seeing these data, Wang Bin said: “Master Qiu! Look, before the engine stopped, there was a problem with the fuel system, and it didn’t take long for the problem to deteriorate rapidly before the plane landed, causing the engine fuel. When the supply is disconnected, the engine will stop without fuel supply.”
After reading the data records on the engine, Master Qiu also nodded and said: “This is actually the problem. In other words, the cause of the aircraft accident should be a problem with the oil pipeline or the oil pump, but it’s no wonder we Many re-ignitions failed.”
And Wang Bin nodded and said: “The possibility is very high, but it may also be caused by the falling off of the oil screw or the interface.”
With the data on Wang Bin and their Tiangong technology engine, it was much easier for everyone to find the cause of the crash, so everyone immediately began to look for the oil system of the wreckage of the aircraft.
And soon, someone made a discovery.
“Everyone, come and have a look, I’m very likely to find the cause of this accident.”
Following the shouting of the staff member, Wang Bin also poked the professor and waited. He immediately walked up and came to the staff member to take a look.
It turned out that the place where the worker was located was a fuel pipeline connection on the plane. However, at this time, many parts of the fuel pipeline near this connection were burned down during the crash, but from the surrounding wreckage. Come, there are obvious oil stains in good places.
At this moment, someone else found a strange place on the side, that is, they found a broken screw near the oil pump not far away, and according to his analysis, this screw did not crash in the plane. In the process, it fell and cracked. The most important thing is that this screw is the screw that used to firmly fix the oil pump and the oil pipeline.
After finding this, everyone at the scene has already been targeted, and they have found the main reason for the accident.
In other words, the accident was actually caused by a small crack in such a screw.
Because the purpose of this screw is to fix the oil pipeline and the oil pump, the rupture of this screw caused the screw to loose and finally detach, which directly caused the main oil pipe to fall off, causing the plane to crash.
When the results came out, everyone stared blankly at the screw with obvious cracks, and everyone felt an indescribable feeling in their hearts.
No one thought that the most important cause of the accident was actually caused by a small crack in this small screw.
After coming over for a while, Master Qiu directly said loudly: “I will immediately check all the screws of the same type and which manufacturer produced this screw. At the same time, I want to know how many important official companies we have are using this type of screw. ”
It is obvious that Master Qiu was very angry at this time, but it is no wonder that even at this time, Wang Bin’s heart is not angry.
Soon, the manufacturer of the aircraft inspected the screws of the same batch, the same type, and the same manufacturer. As Wang Bin and others expected, the quality of these screws did not meet the requirements of aviation screws.
At the same time, they also found the manufacturer of this screw. In Wang Bin’s mind, they guessed that this must be the screw produced by an official company, but this is not the case. The screw is not a domestic official company. What is produced is not produced by a private enterprise, but produced by a joint venture.
When this structure came out, everyone felt even more uncomfortable, especially the factory personnel who produced the improved version of the No. 6 aircraft.
Because the suppliers of most parts in their factories are basically official companies, only small parts and unimportant parts will be purchased externally, and screws are one of them.
However, their factory also clearly stipulates that the procurement of parts and the selection of processing companies must be domestic enterprises, and no foreign capital participates in enterprises.
However, the situation is different from what they thought. It is obvious that there is a problem in the purchasing department of their factory, and it is still a serious problem, as well as the quality inspection department of their factory’s outsourcing parts.
