To build a machine that moving just upwards, we need to have a wing that moves some air down to move the machine upward. Of course, the rotational movement is the easiest way to achieve this. To do this, it’s just enough that several blades, like the blades of a fan, connect to the bar (shaft) on the top of the machine to do the lift by turning it. The blades of a helicopter is very similar to airplane, with the difference of being narrower and longer, because it needs to spin faster and produce more power in the air. By turning the helicopter blades, the helicopter’s body tends to rotate in the reverse direction because of the lack of normal force. To prevent this, a force is needed to prevent the body from rotating. This force is generated by the helicopter tail’s blade. So, actually, every kind of rotation of the helicopter is done by this tiny blade. By increasing or decreasing the power of the tail blade, the helicopter revolves around its axis.
In this analysis, it has been tried to simulate the flow of air over a helicopter in a short period of time using the Ansys Fluent software.
