Rotors are never enclosed. The control propellor is sometimes enclosed because the designer feels it is safer and more aerodynamic.

Why do some helicopters have enclosed tail rotors?
An enclosed tail rotor is safer and resistant to fouling.
Are rotors used to help lift a helicopter off the ground?
The rotors are used for lift and thrust on a helicopter.
What are helicopter rotors made of?
Titanium or composites. There are also steel and aluminum rotors.
What were the rotors from the first helicopter made from?
They were aluminium
Why does a helicopter use rotors instead of nozzles?
Because at present rotors are more efficient
How far from the helicopter are the rotors when in motion?
it is probably 1-3 feet depending on the helicopter
What do the wings of an airplane and the rotors of a helicopter have in common?
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.
Which well known helicopter has 2 rotors?
That is the Chinook.
How many wings does a helicopter have?
Helicopters do not have any wings. Airplanes have wings Helicopter has rotors. A helicopter has at least two sets of rotors. One rotor creates lift ( Main Rotor on the top ) & the other prevents the helicopter from spinning in circles( Tail Rotor).
How helicopter go up?
The rotors on a helicopter are slanted and shaped so that when the rotors spin air slips right under the rotor and get pushed down therefore creating lift.
What are the two small propellers on a helicopter?
Propellors are on airplanes. Helicopters call them rotors. The small rotor on the back of the helicopter is used to counteract the torque created from the engine driving the main rotors.
Why do some helicopters have a small tail rotor?
Tail rotors are to correct the effect of engine torque and help steer the helicopter
