How Kingfisher Inspired Bullet Trains

When the bullet train was first shown to the world in 1964 it was praised as a triumph of engineering. However, a major design flaw was produced when the trains would leave tunnels. Going faster than 200 miles per hour (320 kmph), the Shinkansen train would become a rifle, blasting out of the tunnel with an explosive bang.
Known as tunnel boom, it is created by the train forcing air along the enclosed tunnel, and building up the air pressure until it reaches the end of the tunnel when it is released in the form of a sonic boom.
Many people reported that they could hear loud bangs up to 1312 feet (400m) away. As a result, Japan set a decibel limit of 70 to prevent further noise-pollution levels.
Then, in 1994 an engineer and birdwatcher Eiji Nakastu found inspiration from the kingfisher, and thought about ways it could be applied to the train. After many tests, the result was a nose design similar to that of the kingfisher that offered better performance, and solved the noise issue.

Once again God did it first

I'm glad to see that an example of engineering is inspired by nature for once! 😁

[@aakashchheda8688]

Nature is full of solutions for our man made problem, it's only a matter of time before we realize what's already in front of us.. ✌

I guess my pen cap was inspired by this bird too

[@ameya88]

Knowing i will never sit in bullet train still watched it

[@vj.joseph]

I was wondering why they all had such shapes.

[@pedarsedaniel30]

Great video! What's the background music?

I guess nature has every ansewer we need. We just need to notice
