Special Course on Skin Friction Drag Reduction Held in Rhode-St-Genese, Belgium on 2-6 March 1992 (Reduction de Trainee de Frottement).

摘要

Lecture notes for the AGARD Fluid Dynamics Panel (FDP) Special Course on Skin Friction Drag Reduction have been assembled in this report. The aim and scope of this Course was to provide an overview of the state of the art of current technology programmes focused on reducing aircraft drag caused by skin friction. This Course is complementary and provides an update to topics reported in two previous FDP Special Courses held in 1977 and 1985. This report provides a review of recent progress in the field of skin friction drag reduction for transport aircraft. It provides a general introduction to the technology and then focuses on two specific aspects of drag reduction: maintaining laminar flow by controlling transition and manipulating the turbulence structure in boundary layers to help reduce skin friction. Technology associated with the use of riblets, LEBU, polymers, additives, etc., is also reviewed. The material assembled in this report was prepared under the combined sponsorship of the AGARD Fluid Dynamics Panel, the Consultant and Exchange Programme of AGARD, and the von Karman Institute (VKI) for Fluid Dynamics.
