They're hooked to a transmission which is hooked to an engine.

Why does the rotors spin on an helicopter?
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.
Do helicopter blades break the sound barrier?
No
How does a helicopter get its lifting force?
The rotor blades relieve the air pressure from the helicopter forcing it to lift.
What energy causes blades to spin?
Rotational energy
What happens if the blades stop spinning on a helicopter when it is in the sky?
It would crash, but that would only happen if the transmission locked up. If the engine stops, the rotors would continue to spin and the pilot would autorotate the craft to the ground.
How do helecopter blades spin so fast?
Helicopter blades operate from a transmission or gearbox immediately under the blades. They have to spin fast to give the helicopter lift. Once they are in the air the blades twist slightly to give forward motion.
What makes a helicopter tailspin?
What do you mean by tail spin? How the blades turn? How the back of the helicopter turns?
How fast do the tips of helicopter rotor blades go?
Some helicopter main rotor blades spin at roughly 185 rpm and extend out up to 20 ft so your question is subjective to the helicopter you are speaking of.
What is the top part of a helicopter called?
The top part of a helicopter would most commonly be considered the rotor blades (which spin to provide lift).
What is helicopter rotor and propeller?
The rotor is like the engine to the propeller. A propeller is the fan like blades on the top that spin to make the helicopter fly.
What trees have helicopters?
The Acer Maple tree has seed pods designed to spin like little helicopter blades.
How helicopter work?
My understanding of how helicopters work is that they (suck) the air from above the blades and (blow) it down wards to create lift. the rear blades counter the spin of the top blades of it wasn't for them the helicopter would just spin round in circles (fun but not recommended) :-)

What cause the helicopter to lift up?
The rotating blades are angled in the same direction (at about 35 degrees) and spin fast enough for the air pressure beneath the helicopter to be higher than above so much so that the helicopter lifts off.
What is on top of a helicopter?
Rotor blades are on top of a helicopter.
What is the blades on a helicoptor called?
The blades on a helicopter are called rotor blades. They are attached to the rotor mast and rotate to provide lift and control for the helicopter.
How is a helicopter different from an airplane?
A helicopter has rotor blades and an airplane does not.
