    Abstract

    Flow over cropped delta wings having a leading edge sweep of 65quot; and aspect ratio of 1.38 are coinputed using the DFVLR Euler code. I3oth sharp and round leading edges are considered. Calculations are pcrforrlied for angles of incidence of 10quot;, 20quot; and 24.' for free-steain Nlach number of 0.95 and for angles of incidence of 2quot;, lo' to 30quot; (5') for free-stream mach number of 04. Influence of grid refinement and surface pressure evaluation on the solution are also studied.
