Autogyro rotor blade generating lift by rotation

摘要

The present invention includes a base-side internal profile region (9) having a first profile (21c) and a distal-side main profile region (21e) different from the first profile (21c) ( 10) and the profile depth curve (22) monotonically decreasing in the longitudinal direction of the auto gyro rotor blade (1) from the region of the blade base (2) in the direction of the blade tip (3) to generate lift. The present invention relates to an auto gyro rotor blade. According to the invention, the autogyro rotor blade (1) has a twist with a twist curve (23) that decreases monotonically from the region of the blade base (2) in the direction of the blade tip (3). 23) has a variable slope in the internal profile region (9) and / or the main profile region (10), the torsion curve (23) is concavely curved in this region (9, 10).
