Abstract

A suction arrangement for drawing off a boundary layer on an aircraft comprises a suction arrangement including an outer skin having suction surfaces in critical flow areas, and at least one air breathing engine providing suction. Bleed air is drawn from a comparatively high-pressure region of the engine by means of a branch line and the bleed air is used for driving a turbine of at least one turbo-supercharger assembly. A compressor of the turbo-supercharger assembly or assemblies serves as the suction source for drawing off a boundary layer at the suction surfaces in critical flow areas.
