What are the serious consequences of foreign matters in aircraft engines
Experts said that coins are wear-resistant steel. Once they enter the engine, many rotating parts will be damaged during high-speed operation. When the air flow is inhaled from the front to the back, the fan will be further damaged, or even enter the blade combustion area, or even lead to the overall scrapping of the engine. I really want to thank the passenger who found the abnormality, and report in time.
Then throw the coin into the engine how much is it worth. This is actually a very difficult account. Today, the engine needs to be disassembled if it's difficult to find out. It needs to be installed and tested again. The maintenance of the aircraft is similar to that of the 4S shop. There are many ways to do it, and it won't cost a lot of money. If no one reports it, one or several blades in the engine will be damaged as soon as the engine starts and jingles, starting from $10000, excluding the labor cost.
There is an analysis of engine failure caused by foreign matters in the runway on the official website. It is believed that the maintenance cost of engine damage caused by such accidents can reach up to 20% of the price of the engine. If the card is the upper limit, the cfm56-5b engine is thrown into the coin. The new price is about 50 million RMB. So the claim for '8 million' is probably from here.

Doesn't it mean that the engine has to withstand the impact of birds? Why is a coin so close to the enemy? Indeed, before the engine is put on the market, it has to go through tests including swallowing birds, swallowing hailstones, etc. after swallowing, it must be safe, the fragments can't fly around, and the jargon is tolerance can't fail. But it doesn't mean you can work safely. In fact, a little hard things will damage the engine. The track foreign body mentioned above, scientific name FOD (foreign object debris). Anti FOD is the most important daily work in every airport.
