The name of the product is the beak shaped Japanese bullet train.
How long it has been around
The bullet train was first launched in the year 1964, and at the time, it was the globe’s first high-speed rail network. It was also famously known as yume no chotokkyu, which means the super-express of dreams (Hood 18). The train was created against all odds, in the face of technical hardships, public opposition, and astronomical costs. However, the train was causing a loud booming sound when exiting typical train tunnels (Mara 11). It turned out that the booming was attributable to the shape of the train’s face. This is what is inspired the creation of the beak shaped bullet train in the 1990s.
How it uses biomimicry in its presentation
The aerodynamics of this train was inspired by the shape of the beak of a bird. As such, the engineers modeled the train after a kingfisher-this bird has a big head and a beak that is long and narrow.
Interesting facts of how the development of the product came about
In analyzing the reasons why the first bullet train was making a lot of noise, engineers discovered that the cushion of air accumulating in front of the train as it travelled at a speed of 300km per hour was responsible for the booming sound. One of the engineers attempting to work out this problem was a bird watcher. He had observed a kingfisher bird as it dove down through the air, go into water and created very little splash. This is when he thought of applying this principle to the shape of the front of the bullet train. He thus shared this idea with other engineers and ended up modeling the front of the train like the face of the kingfisher (Mara 13). The end product was a train that had a pointed part to it similar to that of the kingfisher’s beak. And needless to say, when the new model was put to test, it moved through without creating the boom. The train ended up saving them 10-15 percent more energy since it was more aerodynamic.
