Why is the coin thrown into the engine of the plane, will not bring good luck

Nowadays, air travel involves a number of customs and superstitions. The most famous and least understood can be considered a round of applause for the pilots, which they do not hear. But this ritual are harmless, unlike some others that seem to think the passengers on the go.

In 2019 people in China Lu Chao was fined 17 thousand dollars thrown into the engine of the Airbus A320neo owned by the airline Lucky Air a few small coins. What could happen if the action Chao went unnoticed and the plane took off with a small change in the motor?

Act Lu Chao was unexpected for all and forced the ground crew to carefully monitor the aircraft and what occurs near them. It turned out that the man flying for the first time and so decided to quit for good luck in the engine over a few coins for 1 yuan. Flight was cancelled, and superstitious passenger is the court obliged to compensate all related expenses.

After this incident, many wondered how pennies could hurt the huge ship? It turns out that their petite size does not mean that they can't cause the engine critical damage. About the danger of such foreign objects told reporters Javid Bayandor — founder and Director of the laboratory of Crashworthiness for Aerospace Structures and Hybrids (CRASH) of the faculty of mechanical engineering and aerospace engineering University at Buffalo (USA).

Engines are designed with the expectation that they will get foreign objects of sufficiently large size, for example, birds. But here play a role not the size of objects and the properties of the materials of which they are composed.

But that's not all. Javid Bayandor added that small and hard object, hitting a running engine gets a huge boost. Because of this, even the coin is a deadly danger for those people who are at a considerable distance behind the ship.

In the most simple cases, getting coins in the power unit will cause the withdrawal of the aircraft from the flight for his thorough technical inspection and possibly repair. As the modern aircraft is a very complicated technique, this work can take weeks and even months, during which aircraft operations will be impossible.
