System for influencing barrier layer in rotor blades of e.g. bypassing engines of helicopter, has set of apertures formed in location at outer skin of rotor blade, where flow medium is pumped in radial direction by hollow channel
The system has a set of apertures such as perforations, holes, slots or apertures in other geometry, formed in a location at an outer skin of a rotor blade, where the rotor blade is hollowly executed. Flow medium e.g. water or air, is pumped in a radial direction by a hollow channel. Pump power is generated to convey the flow medium in the hollow rotor blade by the centrifugal force acting in a set of hollow chambers of sheets on the mass of the flow medium. A barrier layer is sucked on a rotor blade surface by the apertures in the hollow channel, and emerges at a blade tip.
