The invention pertains to a spoiler (5) for an aerodynamically active surface of an aircraft (1), particularly for an airfoil of an aircraft, wherein said spoiler is supported on the aerodynamically active surface such that it is articulated about an axis (11) extending transverse to the air flow direction and can be adjusted relative to the air flow. According to the invention, the spoiler features two or more segments (6, 7) that are arranged behind one another referred to the air flow direction and extend transverse to the air flow direction, wherein said segments are connected to one another in an articulated fashion and can be adjusted to different angles referred to the air flow. The successively arranged segments of the spoiler (5) can be actuated, in particular, by means of an actuating device (8, 9, 10) in such a way that the rear segment (7) is adjusted relative to the air flow by a greater angle than the front segment (6).

1. An aircraft aerodynamic body comprising: an aircraft airfoil having supporting structure,a spoiler supported on the aircraft airfoil, andan actuating device,wherein said spoiler is supported on the aircraft airfoil such that the spoiler is articulated about an axis extending transverse to an air flow direction and is adjustable relative to air flow, the spoiler comprising at least a front segment and a rear segment arranged behind one another with regards to the air flow direction, extending transverse to the air flow direction, connected to one another in an articulated fashion, and adjustable via the actuating device to different angles with regards to the air flow,wherein the actuating device comprises an actuator and a coupling mechanism, the actuator being coupled between the supporting structure of the aircraft airfoil and the front segment of the spoiler, the coupling mechanism comprising a toggle lever comprising a first lever rigidly connected to the rear segment and comprising a second lever, the second lever being coupled to the first lever at a first articulation and coupled to an abutment at a second articulation, the abutment being on the supporting structure or being formed by a base point of the actuator,wherein the toggle lever forms a step-up gear, the step-up gear causing the rear segment to be adjusted by a greater angle than the front segment when the spoiler is actuated by the actuator,wherein the aircraft airfoil comprises a main wing having a rear side with regards to an air flow direction and comprises a high-lift surface arranged on the rear side of the main wing, wherein said high-lift surface is extendable from a retracted position such that a gap conducting air from an underside of the main wing to an upper side of the high-lift surface is exposed between the main wing and the high-lift surface, and wherein the spoiler is arranged on an upper side of the main wing and is pivotable about an axis extending in a wingspan direction of the airfoil,wherein the spoiler is adjustable upward from the upper side of the main wing to reduce lift such that the rear segment is upwardly adjusted relative to the air flow by a greater angle than the front segment, and wherein the spoiler is adjustable downward from the upper side of the main wing into the gap to increase lift when the high-lift surface is extended such that the rear segment is downwardly adjusted relative to the air flow by a greater angle than the front segment. 2. The aircraft aerodynamic body according to claim 1, wherein the first lever is rigidly connected to a lower side of the rear segment of the spoiler and bent at a right angle such that the first lever extends forward underneath the front segment of the spoiler, wherein the second lever has a first end and a second end, wherein the front end of the first lever is coupled to the first end of the second lever via the first articulation, wherein the second lever is arranged in an angled fashion relative to the first lever, wherein the second end of the second lever is fixed on the abutment via the second articulation. 3. A combination for an aircraft aerodynamic body having a main wing and supporting structure, the combination comprising: a spoiler adapted to be supported on the aircraft aerodynamic body, andan actuating device,wherein the spoiler comprises at least a front segment and a rear segment arranged behind one another, connected to one another in an articulated fashion, and adjustable via the actuating device to different angles,wherein the actuating device comprises an actuator and a coupling mechanism, the actuator being coupled to the front segment of the spoiler and adapted to be coupled to the supporting structure, the coupling mechanism comprising a toggle lever comprising a first lever rigidly connected to the rear segment and comprising a second lever coupled to the first lever and adapted to be coupled to an abutment being on the supporting structure or being formed by a base point of the actuator,wherein the toggle lever forms a step-up gear, the step-up gear causing the rear segment to be adjusted by a greater angle than the front segment when the spoiler is actuated by the actuator,wherein the spoiler is arranged on the upper side of the main wing and can be pivoted about an axis extending in the wingspan direction of the airfoil,wherein the spoiler is adjustable upward to reduce lift such that the rear segment is upwardly adjusted relative to the air flow by a greater positive angle than the front segment, and wherein the spoiler is adjustable downward into a gap to increase lift such that the rear segment is downwardly adjusted relative to the air flow by a greater negative angle than the front segment.
