Helicopter Blades are bolted onto the main rotor
The main blade on a helicopter is the 'rotor'

A rotor.
It has a rotor blade instead of wings.
It is called the rotor.
you go to reality tv go on to the helicopter blade jump and flip then you land on the middle of the helicopter blade then ta-da your brake dancing.
The angle of the rotor blades.
The rotor blade is the airfoil on helicopters.
Since air is not inherently flammable, there is no speed at which a helicopter blade would catch the air on fire.
Bristow has many types of helicopter with, 3, 4 and 5 blade rotors
If a helicopter blade stops spinning in the sky, the helicopter will experience a rapid descent known as autorotation. This is when the airflow through the rotor keeps the blades spinning, allowing the helicopter to land safely even without engine power. It requires skilled piloting to execute successfully.
Q: Why is a helicopter called a "Chopper"? A: I think the names comes from the sound of the blades make: whop-whop or chop-chop. FYI, the helicopters that have the loud popping of the blades are usually a 2-blade of the Bell Helicopter design. The multi-blade helicopters do not have a sound as distinctive as the Bell helicopters. The sound comes from the blade striking the vortex generated by the blade ahead of it.
