How works helicopters?

Question

explain with structures and maps.

Answer 1

1) The main rotors generate lift. For climbing the power is increased.

2) Tilting the rotor disc in the direction where you wish to go makes it move in that direction.

3) The tail rotor gives it stability and prevents it from spinning in the opposite direction of the main rotors.

In YA you dont expect structures and maps to be provided.
