ROTOR BLADE FOR HELICOPTER

摘要

PROBLEM TO BE SOLVED: To provide a rotor blade for a helicopter comprising an aerodynamic control flap being controlled by using a control means even under centrifugal load and free from the inclination of the control means and a control face. SOLUTION: A control rod 30 is mounted through an anti-friction bearing 46 and a bolt 41 extended in the longitudinal direction of the wing, and a means for receiving the centrifugal force of the control rod 30 produced from the rotation of the rotor blade through a camber flap 10 is mounted. The means is composed of a thrust bearing 44 mounted between the control rod 30 and the camber flap 10, and an energizing spring 45 for reducing the play of the thrust bearing 44.
