CALCULATION OF OPTIMUM SUPERSONIC DELTA WINGS

This paper presents the distributed and total drag-due-to-lift in closed form by means of linearized supersonic wing theory for delta wings having arbitrary warp described by a symmetrical ten-term power series expansion for which the loading was reported on previously by the author and others. For both sonic and supersonic leading edges one hundred drag contributions are derived, ninety of which are interference terms induced by the interaction of each loading with each of the noncorresponding downwashes. For subsonic leading edges additional terms are included to account for the suction forces induced by the leading edge pressure singularities. The mean chord shape required to deflect under aeroelastic load to the desired shape computed was programmed for the IBM 704 Digital Computer.
