Effects of contamination on riblet performanceThin-element polymeric film riblet surfacing materials previously shown to behave similarly to v-groove riblets in the reduction of aerodynamic drag have been tested to ascertain the effects of groove contamination. Three different levels of contamination were simulated for each of two kinds of contamination. Such contaminants as oil drops and condensates have no significant effect on drag reduction. Atmospheric particulates may, however, degrade riblet performance.
