| Abstract: | An experimental research of drag reduction using riblets for the Y-7 airplane was conducted in the FL-8 wind tunnel of 627 Institute. Special designed riblet films were applied to the part of wing and tail of the Y-7 airplane model covered with turbulent boundary layer flow.The experiment model which is metallic and 1/12 original Y-7 airplane was provided by Xian Aircraft Company. The experiment results show that about 5%-8% drag reduction can be obtained by using riblets. |
