This made them surprised at the quality of the aircraft. After all, only the tail of the aircraft was slightly damaged under the impact of such intensity. If it was replaced by other aircraft, such impact would definitely be fragmented by the impact.


    You know, this is a plateau airport landing! The speed of the aircraft at the time of landing itself is much higher than that of the airport at the plain, so its strength naturally exceeds that of the plain airport at the time of impact.


    As the inspection of the aircraft continued, they soon completed the inspection of the body and were relieved of the condition of the organism. As long as the dents at the tail were properly repaired, the most important thing now is to determine the damage of the engine.


    After all, the engine is the most important to the damage degree of the aircraft. If the engine is seriously damaged, the two engines can only be scrapped and need to be replaced. At the same time, all the previous flight test subjects must be overturned and restarted.


    Like the previous inspection of the aircraft body, the inspection of the engine also starts from the engine casing, but when they see the engine casing, they can''t believe their eyes.


    Because at this time, although there are many blood stains hit by birds on the casings of the two engines, there are no cracks and dents on the casings of the engines. When they wipe off these blood stains, the casings of the engines are still brand-new, and there is no trace of damage at all.


    However, even so, they are still very worried about the internal situation of the engine. After all, from the traces just on the engine shell, we can see what the engine has experienced before.


    Therefore, many ground crew members worked together to open the engine casing and began to check the engine itself.


    However, at the moment of opening the engine casing, these ground crew stared at everything in front of them. Everyone''s head couldn''t react, because everything inside the engine fundamentally subverted their cognition of the fast engine.


    You know, even the propeller aviation engine will cause great damage or even direct damage to the propeller after being hit by birds, but at this time, after the two engines are involved in many birds, they don''t see any trace of damage inside the engine, even the fan blade.


    "Lao Yi! The difficulty is that we were wrong before. In the past, no bird was rolled in by the engine, but hit the shell of the engine and bounced off. In fact, it didn''t enter the engine, and what we saw before was just an illusion." at this time, a young ground crew asked a ground crew member with a higher grade.


    "No! We can never read it wrong. After all, if there is only one person, it may be an illusion, but so many people clearly see it, it will not be an illusion.


    What''s more, you see, there are some feathers here, so we can''t be wrong. Just because of the quality and performance of this engine, even if these birds are involved, the damage to the engine is not as big as we thought.


    We can''t know the details until we check. Well, don''t say so much. Let''s check the two engines thoroughly first! See if the engine is in good condition as we can see! "


    .....................


    Shortly after the test flight of the No. 9 aircraft collided with the birds, Wang Bin received a call from Qiu Tuan. After all, after a series of test flights of the aircraft from Tiangong technology, Qiu Tuan was responsible for the subsequent test flights.


    "Mr. Wang! There is something wrong with the No. 9 plane that was tested! When the plane was flying to an airport and preparing to land, it directly collided with an oncoming group of medium-sized birds, and in this collision, many places were hit, but fortunately, the condition of the body was very good and there was no big problem.


    At the same time, when encountering the birds, many birds were rolled into the engine and had a certain impact on the fan blades of the engine. Among them, two fan blades fell off about 0.5mm blade tips due to impact.


    Therefore, we are preparing to disassemble the two engines and transport them to your Tiangong technology for maintenance.


    At the same time, the test flight of our No. 9 aircraft may also be temporarily terminated. After all, our technicians can only check some general conditions of the engine, and can''t check the whole engine at all. The most important thing is the core condition of the engine. We don''t know at all, and naturally we can''t conduct a thorough inspection, "Qiu Tuan said on the phone.


    "No! Qiu Tuan! It doesn''t need to be so troublesome at all. I''ll bring our company''s professional repair and maintenance to you later. Our technicians will take professional equipment and directly inspect these engines at the airport. If the situation is not very bad, don''t return to the factory for repair at all. It can be solved directly at the airport," Wang Bin said.


    "What? You don''t have to go back to the factory for maintenance. Mr. Wang, please don''t joke. After all, this matter can''t be joked." Qiu Tuan said seriously after listening to Wang Bin''s words.


    "Qiu Tuan, please don''t worry! How can I joke about such things? When we first designed the real tg-s002 engine of Tiangong technology, for the convenience of maintenance, we had considered a variety of situations. Unless the core engine is seriously damaged and needs to be returned to the factory for maintenance, other situations, including the damage of engine blades, are acceptable The maintenance can be carried out directly on the machine without disassembly, and also includes the replacement of fan blades, "Wang Bin explained.


    "Mr. Wang, it''s true that your engine can still be repaired on board when the fan blades are damaged, and even the engine doesn''t have to be disassembled?" Qiu Tuan was shocked by Wang Bin''s words. After all, if the blades of ordinary aeroengines are damaged, there is no way except returning to the factory for repair, But the engine of Tiangong technology doesn''t even need to be disassembled. It can be repaired directly on the machine.


    Most importantly, according to Wang Bin''s previous words, even a comprehensive inspection can be carried out on the aircraft without dismantling at all, which is definitely a challenge to his knowledge of aeroengine knowledge.


    Of course, this is what he would like to see most. If what Wang Bin said is true, it means that if they are equipped with tg-s002 engine of Tiangong technology on a large scale in the future, they will not have to return to the factory frequently in terms of maintenance. As long as there are problems, they can solve them on the spot. This is definitely a great good news for Qiu Tuan.
