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.

摘要： The invention related to an autogyro (1) comprising a body (2), a mast (3) arranged in the upper region of the body, a rotor (4) which is rotatably arranged in the region of the end of the body (3) and which can be put into autorotation by an air flow, a drivable propeller (6) which is arranged in the region of a rear body end (5) and which generates a propulsion of the autogyro (1), a guide mechanism (7) arranged behind a propeller (1), and at least one brace (8) which extends past the propeller in the longitudinal direction of the autogyro at a radial distance from the propeller (6) in an outwards direction and which connects the guide mechanism (7) to the body (2). According to the invention, the guide mechanism (7) has a guide mechanism protrusion (9) which is arranged coaxially to the rear body end (5) and which extends forwards from the guide mechanism (7) in the direction of the rear body end (5) at a distance therefrom. Furthermore, at least the region of the rear body end (5) of the body (2) and the guide mechanism protrusion (9) together form a streamlined outer contour. The invention further relates to an autogyro in which the mast (3) is designed, in particular the mast is arranged and/or inclined relative to the propeller (6), such that when rotating, the blades (17) of the propeller (6) always only partly overlap with the mast (3) in a respective overlap region (21) when viewing the autogyro (1) from the rear.
