dragging
The freedom given to each blade of a rotor to allow it to move in the plane of rotation independently of other blades. It is basically the angular oscillation of a rotor blade in the plane of rotation about a substantially vertical axis. This is to avoid bending stress at the root. The blade is allowed to lead or lag about a dragging hinge, but movement of the hinge is restricted by some form of drag damper to avoid undesirable oscillations. The fore-and-aft movement of the tip of a helicopter rotor blade in its plane of rotation. Also known as lead-lag motion or drag.
