it is probably 1-3 feet depending on the helicopter
The rotors are used for lift and thrust on a helicopter.
A helicopter typically has mechanical energy in the form of both potential energy (stored energy due to its position) and kinetic energy (energy of motion as the rotors spin).
Just looking at the gyrations of the helicopter rotors made me dizzy. Gyration= circular or spiraling motion
Titanium or composites. There are also steel and aluminum rotors.
They were aluminium
Rotating rotors on a helicopter create lift by generating airflow over the blades, allowing the helicopter to take off, hover, and maneuver in different directions.
Because at present rotors are more efficient
100 Ft.
It is not really about how many feet you are away from it. it is more about where you are standing near it. you can perfectly walk under the blades of a helicopter while in motion. just try not to jump or throw things things in the air. always enter the helicopter from the front of it, not from the back where the tail rotor or tail boom is
READ THIS - GOOD INFORMATION The wings of an airplane and the rotors of a helicopter both help the object fly. Without those the object could not fly because the wings of an airplane have wind going past it which keeps the airplane in the air. The rotors of a helicopter spin in the wind and help the helicopter fly.
That is the Chinook.
The rotor blades on a helicopter work the same way as wings on a fixed wing aircraft. The air passing faster over the top of the airfoil generates lift. Helicopter rotors spin so that the lift is generated without having to have forward airspeed like a fixed wing aircraft.
