A method applies aerodynamically functional film to a body around which complex flow occurs. The method includes: determining flow lines on a surface of the body for a predetermined surrounding flow state on a basis of a computer model of the body using a numerical flow simulation; developing at least one surface segment of the computer model provided with flow lines to form a two-dimensional surface; locating at least one coherent field in the developed surface segment having local flow directions readable at the flow lines in a predetermined angle range around a main flow direction of the respective field; and applying the aerodynamically functional film to the body within the field boundary of the at least one field located in the developed surface segment in such a way that the aerodynamically functional film is aligned along the main flow direction of the respective field.

Method for applying an aerodynamically functional film

An apparatus is for attaching an aerodynamically functional film to a surface of a body around which flow passes. The apparatus includes: a self-adhesive, redetachable positioning film having positioning aids for the exact positioning of the positioning film on the surface of the body around which flow passes and having at least one application area for the aerodynamically functional film that is to be applied.
