The purpose of this text is to present methods for computing drag polars of conventional airplanes at Mach numbers below 1.0. The word conventional is to be interpreted such that airplanes with highly swept, low aspect ratio wings (Л > 35°; A< 4) are excluded.Two methods are presented. First a very fast preliminary design method for estimating drag polars at low Mach numbers. Second a more el…
