Title: AERODYNAMIC BODY
Abstract:
An aerodynamic body for use on an aircraft is presented. The aerodynamic body includes at least a first perforated surface portion (25) and an ice-protection system (31). The first perforated surface portion (25) has perforations, the ice-protection system (31) includes an actuatable element (33) and the actuatable element (33) is movable or deformable between a first position and a second position. In the first position at least a section of the actuatable element (33) is thermally coupled to the first perforated surface portion (25) and configured to prevent an inflow or outflow between a boundary layer of an outer aerodynamic airflow and the aerodynamic body through at least one of the perforations. In the second position at least a section of the actuatable element (33) is distanced from the first perforated surface portion (25) and configured to allow an inflow from a boundary layer of an outer aerodynamic airflow through at least one of the perforations into the aerodynamic body.
