The invention relates to a tragschrauberrotorblatt for autorotator lift generation with a root-side inner profile region (9) having a first profile (21c), with a tip-side main profile region (10) having a first profile (21c) different second profile (21e), and with a profile depth profile (22) decreasing monotonically in the direction of the blade tip (3) in the longitudinal direction of the gyroscope rotor blade (1) starting from the region of the blade root (2). According to the invention, the gyrocopter rotor blade (1) has a twisting with a twisting course (23) decreasing monotonically starting from the area of the blade root (2) in the direction of the blade tip (3), wherein the twist course (23) in the inner profile area (9) and / or main profile area (10) has a variable pitch, so that the twist course (23) in this area (9, 10) is concavely curved.
