Yes, smaller helicopters such as an R-22 or B206 can be placed on a truck and moved with out removing the rotor blades. Generally speaking the blades are removed to protect them and to make lifting the helicopter by crane a much eaiser task.
I have personally witnessed a Bell Jet Ranger helicopter not only transported on a flatbed trailer with rotor attached, but also watched them unload it by simply flying it off the trailer.
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.
They are on special hinges attached to what is called a 'swash plate'
Rotor blades are on top of a helicopter.
A helicopter has rotor blades and an airplane does not.
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
The rotor is the hub and main blades on top of every helicopter.
Helicopter Blades are bolted onto the main rotor
Helicopters have 2 sets of blades to keep the helicopter balanced. This is due to the unique shape of the helicopter.
