Body of Revolution: Surface Sections and Direction


The Body of Revolution component is effectively a wing-type body that is under a loop design mode where the first and last section are coincident and the surfaces are all symmetric about the centerline axis. Similar to a wing component, the U parameter follows the ‘root’ or start of the cross-section location and goes around the center axis on the surface. For hollow BoR geometries, the W location follows the convention of first marching along the inside of the part toward the leading edge and then along the outside of the part toward the trailing edge. Otherwise, when setting Upper or Lower design policy, the W location marches from the trailing edge (aft) to the leading edge (forward).
