Pylon cross-sectional geometries that are believed to reduce pylon/wing installation drag are analyzed. The basic design philosophy is to alleviate flow acceleration near the pylon/wing junction by aerodynamic means. This involves reshaping the pylon, particularly on the inboard side. In some instances this is achieved by moving the pylon trailing edge closure aft of the wing trailing edge. A three-dimensional Euler code was used for the analysis. Promising pylon shapes are identified for further investigation.
