Before you begin reading the article,check out the video below to have an idea about the end result when a bird hits a jet engine while in flight.
The plane was completely destroyed.
Anyone who has at least a basic idea of how airplanes work will agree that take-off and landing are the most difficult and often critical parts of the entire flight, because if there is any malfunction in the engine at this time, then the pilots won’t be able to adjust quickly which will be catastrophic. Nowadays, the blades of the engine are made from very tough and high quality materials which usually don’t break at all. But even then when they are rotating at such high speeds, hitting any foreign object such as birds will cause serious damage to the blades as well as the engine.
Consider the following example. Boeing 737’s speed during take-off is approximately 250 km/h. A crow, whose average weight is around 2 kg, when hits the blade, will have a momentum of around 138 kg m/s. To help you understand how massive this number is, it can be considered equal to 20kg objects hitting your face at the speed of 25 km/h. Yes, that’s going to hurt… a lot.
Reason behind bird strikes
This is actually due to our faults only. Human beings dump their garbage in open fields, and the scavenger birds such as crows come to these places. In case these places are close to airfield, and a plane is trying to land at the same time, when the crow is descending, you can understand what happens when they collide.
To prevent this from happening to passenger planes, they have two engines so that even if one stops working, the other engine can be used to land. Pilots have to go through special training so that they can handle these situations better. Various simulations are also carried out to see the effects of collision while in flight.
In most cases, although the plane is damaged by the collision, passengers are normally safe. However, it is definitely quite scary as you never know what can happen when one engine goes down while in flight.
