A study was made at transonic speeds by the NACA wing-flow method of the pressure-drag reduction obtained by projecting a high-energy jet of air from the nose of a prolate spheroid. Supplementary information was obtained by taking shadowgraphs of the model mounted in a small supersonic tunnel at a constant Mach number of 1.5.
