Abstract : Measurements were taken to determine the effects of varying the gap width of two parallel leading edge slots on the aerodynamic characteristics of a 70 deg swept delta wing. The two major changes over previous model tests were the use of flush slots and study under turbulent boundary layer conditions. The slots were aligned parallel to the leading edges to simulate leading-edge flaps. The report analyzes preliminary computer data and develops a comparative thesis of three delta wing tests.
