How It All Works – This now results in two opposing forces acting on the tail rotor system. The aerodynamic force wants to streamline the blades to zero pitch while the centrifugal force wants to rotate the blades to their maximum pitch. These tail rotor weights produce a centrifugal restoring moment (CRM) because they act [...]
