摘要
An autogyro rotor blade for generating lift by autorotation defines a root-side inner profile region, which has a first profile. The inner profile region has a tip-side main profile region, which has a second profile different from the first profile, and a profile depth curve that decreases monotonically in the longitudinal direction of the autogyro rotor blade from the region of the blade root in the direction of the blade tip. The autogyro rotor blade has a twist having a twist curve that decreases monotonically from the region of the blade root in the direction of the blade tip. The twist curve has a variable slope in the inner profile region and/or main profile region, and therefore the twist curve is concavely curved in this region.
