GetAClass - Physics in experiments

Published on Dec 28, 2022

About :

The video shows the operation of wind turbine blades and a toy paper helicopter. It turns out that a helicopter with 2, 3, 4, 5 blades with the same mass descends at the same speed as a parachute of the same diameter. Therefore, 2 blades already provide effective energy extraction from the oncoming air flow.
