This paper focuses on drag-extraction methods from flowfield wake surveys. For many years, ONERA has developed an original method which aims at improving the understanding of local flow phenomena. The approach consists in decomposing lift and drag into profile and induced components from wake measurements. The definition of drag allows a phenomenological breakdown of the different drag sources, for which the physical interpretation requires an accurate description of the wake phenomena. It is the aim of this paper to closely analyze these drag sources and to establish an accurate breakdown. In the first section, the analytical definition of profile drag is reviewed. Several formulations commonly found in the literature are compared with determine their physical meaning and limits of applicability. From this analysis, a new drag-breakdown method is proposed and discussed. Computational fluid dynamics simulations are carried out to complete this study and to evaluate the accuracy of the new formulation. The latter is then applied to subsonic and transonic flows from wind-tunnel measurements.
