With the fall of the helicopter of Kunlun company, the boss of Kunlun company stood there with a dejected face and stared at the fragmented helicopter for a long time.
And he said softly: "how could this happen! How could this happen? The engine used in this helicopter is clearly a high-quality engine imported from abroad. How can it not fly? It is even worse than the domestic engine. Even in the previous test flight, there was no crash!"
Although the boss of Kunlun company couldn''t figure it out at this time, other personnel of Kunlun company didn''t like their boss. After the plane crash, they immediately began to clean up the mess and immediately began to check the helicopter to see whether there was a problem with the aircraft itself or the imported engine.
Wang Bin and chief engineer Lin also went to the boss of Kunlun company and said to him, "Mr. Du, although you said that your helicopter test flight failed this time, please don''t be sad. After all, there are always failures. Now the most important thing is to find out the cause of the accident and see whether it was on the plane itself or on the engine."
After listening to Wang Bin''s words, Du Haili finally regained his mind. He said to Wang Bin somewhat dejected: "President Wang, I also know this. In fact, I was ready before the test flight.
However, in any case, the engine used in our helicopter is no longer a domestic engine, but a foreign high-performance piston aeroengine. However, the result is worse than using a domestic one, which is the most depressing place for me.
We should know that when we used domestic engines before, at least the aircraft could fly hundreds of meters. Moreover, in the process of so many test flights, although there were various problems with the engine, there was no air parking like this time, let alone crash. "
"Mr. Du! Although your aircraft has been replaced with foreign engines, the performance of foreign engines is not necessarily better than that of domestic engines.
Moreover, the engine sold to you abroad may not match your engine.
The most important thing is that foreign aircraft engine manufacturers will certainly not sell real high-performance engines to you. If I guess correctly, the engine you imported from abroad must be a simple version, and its performance parameters are definitely far lower than the original version! "Wang Bin thought and said.
However, just as Wang Bin had just finished, their technicians of Kunlun company had already had certain results in the inspection of the aircraft.
"Mr. Du! The basic situation has been determined and the cause of the accident has been found." he looked at Wang Bin and shut up.
"President Wang and chief engineer Lin are both insiders. It''s nothing. Just say it! What''s the reason for the test flight failure this time, and even the air parking!" Du Haili said after listening to the staff of his company.
"Mr. Du! According to our inspection, the fuselage structure of our aircraft is OK. The problem, like the situation during our last test flight, also appears on the aircraft engine.
And after carefully checking the condition of this engine, we found that this engine is not the one we asked foreign businessmen for before.
Although the shell of this engine is not much different from what we need to buy before, even in terms of details, the internal situation is very different, especially in terms of horsepower. This engine is at least nearly a quarter smaller than the engine we need.
Because the horsepower of this engine can not meet our requirements, this is the main reason why our light helicopter failed in the test flight and crashed. "The staff member did not hide, but directly told the main reason why the plane crashed.
"What? The engine is not the model our company needs, but another model. Not only in terms of engine performance, this model is far from the one we need to buy before, but even in terms of horsepower, it does not meet the requirements we need." Du Haili was shocked when he heard the staff''s words, But with it came great anger.
So he immediately told their staff: "the things here will be handed over to you first. I want to go back to the company and contact each other. I want to ask the engine manufacturing company why the engine we bought was not sent, but gave us this unqualified engine."
"OK! Mr. Du, leave it to us!" the staff said.
"Mr. Wang! Chief engineer Lin! I have to go back first after such a big event. I thought that as a world-famous aeroengine manufacturer, they would not cheat.
But unexpectedly, the famous foreign engine giant Ross group sent this engine not the one I saw before, but this unqualified product! "Du Haili said.
"Mr. Du, don''t be angry. After all, such things are very normal in China. Let alone your private enterprises. Even domestic official enterprises have encountered such things countless times. After all, foreign manufacturers can''t sell their most advanced products or technologies to us.
If Mr. Du really wants to continue the research and development of your helicopter, I think you might as well think more about Mr. Wang''s proposal before, because according to my experience, even if you go to this foreign company, there will never be any good results! "Said Mr. Lin.
"OK! Chief engineer Lin, I''ll think it over," Du Haili said.
With that, he and Wang Bin exchanged their respective telephone numbers and left in a hurry.
Seeing Du Haili''s departure, chief engineer Lin turned to Wang Bin and said, "Mr. Wang! Fortunately, your Tiangong technology and the technology used are basically designed and manufactured by your company. Otherwise, the result this time will be no different from that of their Kunlun company."
"Who says no, in fact, this is also the reason why we Tiangong science and technology research our own engine. Otherwise, we don''t need to spend so much money, manpower and material resources to develop this engine!" Wang Bin also sighed.
Subsequently, Wang Bin and his colleagues reloaded the UAV onto the truck transporting the UAV, and opened a test flight field in the province of 969 group. They were ready to go back to test the interior of the UAV and sort out the data of the test flight to see if there were any problems in the interior of the UAV and improve it.
