Abstract
The present paper gives a review of various existing methods for reducing base drag of two-dimensional and axisymmetric bodies having a blunt base. These methods include splitter plates, both thin and thick, splitter wedges, base bleed. boat-tailing and various types of serrated trailing edges. The effectiveness of the various devices in reducing base drag is shown and compared. In some cases their influence on the lift of an airfoil is also indicated.
