The size and shape define what the rotor will lift.
Rotor blades are on top of a helicopter.
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.
A helicopter has rotor blades and an airplane does not.
make your blades out of carbon fibre
A Helicopter - the number of blades is irrelevant. On a side note - what keeps a helicopter in the air? It's so ugly the earth repels it!
Helicopters created nowadays generally have 2 or 3 blades. The fastest recorded helicopter has 3 blades. as it revolves more pressure is put forth and therefore the helicopter travels faster
That is a twin rotoe helicopter
No, they are correctly called 'rotor blades'
the big blades
No, helicopter blades do not break the sound barrier. The tips of the blades can approach the speed of sound, but the entire blade does not exceed the speed of sound.
Helicopter blades spin due to the engine providing power to the rotor assembly, which causes the blades to create lift and generate thrust. The rotation of the blades also allows the helicopter to maneuver and change direction in flight.
The rotor is the hub and main blades on top of every helicopter.
