Why are the blades of an aircraft engine twisted into an S shape? What kind of scientific principle is behind it, I am "Uncle Encyclopedia" Uncle Rocket, let us understand it together today!
The s-shape at the front of the fan blade was inspired by the curve at the top of the sand dune. At that time, it was a headache for how to reduce the resistance of air friction on the fan blade. Some people had a sudden inspiration. Why is the top of the sand dune not straight but similar to a crescent shape? Could it be that the top of the dune is the shape with the least friction left when the air flows through it and takes away the sand with high resistance? After the experiment, it was found to be true.
This is the perfect S-curve. Why do the blades of an aircraft engine have to be twisted like this?
