ABSTRACT:
A method for forming turbulators on scale model airplanes used in wind tunnel testing for accurately simulating a transition point on the model surface equivalent to that produced on the full scale airplane. The transition point is where the boundary layer airflow goes from a laminar airflow condition to a turbulent airflow condition. The method relates to applying a perforated tape mask (14) to the model surface (12) at a predetermined location and filling the perforations (15) with a fast cure epoxy (17). After the epoxy has cure hardened, the tape mask (14) is peeled off in the direction of the arrow (16), leaving a series of in situ formed disk turbulators (10) which function to produce the transition point on the model surface.
