Experimental Study On Upswept Afterbody Shapes Of Light Transport Aircraft

摘要

Low Speed Experiments Of Parametric Study On Few Upswept Afterbody Models Were Carriedout In The 0 .9m Diameter. Low Speed Tunnel For Independent Determination Of Profile And Vortex Drag Using 3-D Wake Survey Method, With A Primary Objective Of Providing Preliminary Information AboutudAfterbody Drag Relevant To Light Transport Aircraft . This Study Has Broughtout Particularly The Influences Of Various Afterbody Geometric Parameters On The Vortex Drag.ud
