Main Rotor Head Types Rigid Rotor: Blades are mounted rigidly to the hub, allowing for feathering but not flapping. This eliminates the need for a tail rotor, providing greater hover efficiency and robustness.
Tandem Rotor Helicopter Design and Anti-Torque Systems
Semi-Rigid Rotor: Features two blades mounted on a teeter hinge, allowing the blades to flap as a unit. NOTAR (No Tail Rotor): Uses directed air from the main rotor and a vertical stabilizer to provide anti-torque.
Unlike fixed-wing aircraft, helicopters generate lift through rotating airfoils, allowing for vertical takeoff, landing, and hover capabilities. The conventional tail rotor, pusher configuration, and ducted fan each offer unique advantages depending on the helicopter's intended mission.
Tandem Rotor Helicopter Configurations and Design
Transverse Rotor: Features two rotors mounted side-by-side, rotating in opposite directions. The design and placement of this component create distinct handling characteristics and safety profiles.
