The term 'chopper blades' can be summarized as rotors, which are six-letter components of a helicopter. Rotors are the main source of lift and thrust for a helicopter, and they consist of two or more blades that rotate around a central hub. The blades are connected to the hub by a system of bearings and linkages, and they are powered by an engine. The rotors provide the necessary lift and thrust for the helicopter to take off, hover, and land.
