<p>A rotor blade (5) for a driven horizontal rotor (1) of a rotary-wing aircraft comprises an elongated main body (15) which includes a leading edge (12), a trailing edge (10), and an upper surface (11) extending between the leading edge (12) and the trailing edge (10). The rotor blade (5) further comprises at least one flap (13) having a front end and a rear end and mounted to the main body at its front end swiveling about a swiveling axis (14) running in parallel to the longitudinal axis of the rotor blade (5). The flap (13) has a basic position in which it lies flat against the upper surface (11) of the main body (15). Further, the flap (13) is designed to be passively swivelled by aerodynamic forces and inertial forces about its swivel axis to raise its rear end above the upper surface (11) of the main body (15), and the flap (13) is swivel mounted to the main body (15) in such a way that a reset force acts upon the flap (13) to reset it into its basic position.</p> |
