Hoofdrotortype refers to the configuration of the main rotor system on a helicopter. This classification is based on how the rotor blades are attached and articulated to the rotor head, which is the central component connecting the blades to the helicopter's transmission.

In a fully articulated rotor system, each main rotor blade has its own hinge, known as a
