摘要
A stealth craft's aerodynamics and flight stability are improved with the use of a multi-faceted dihedral planform. The stealth craft includes a multi-faceted dihedral planform extending in a direction from a front to a rear of a craft (or wing) and defined by a first set of facets followed by a second set of facets. In an exemplary embodiment, the first and second sets of facets have an angle of incline that is ascending and descending, respectively, with respect to the direction of the planform. Selected ones of the first and second sets of facets are configured with insufflation slots for improving aerodynamics and stability, the insufflation slots extending spanwise in a direction transverse to the direction of the planform and provided to insufflate a fluid to form a cushion of air along the multi-faceted dihedral planform for improving aerodynamics and stability.
