"A 49 degree swept-wing complete model equipped for high-pressure blowing full span at two chordwise locations at the leading edge of a full-span wing and over a half-span flap has been tested in the Langley full-scale tunnel to determine the effectiveness of blowing at the leading edge as a supplementary leading-edge stall control at high lift coefficients." The effect of blowing on the lift characteristics, pitching-moment characteristics, and drag characteristics of this particular model is described.

Report presenting an investigation in the transonic tunnel to determine the aerodynamic loading characteristics of a 3-percent-thick, aspect-ratio-2.06, 60 degree delta-wing-body combination at a range of Mach numbers and angles of attack. Results regarding pressure distributions, spanwise loadings, integrated wing coefficients, and tabulated pressure coefficients are provided.

The following report describes a gaseous scintillation counting system, including the production and operation of the counter.

Results of previous toroid tests with 28 micro 1600 fired ThO2 spheres are analyzed. Four possible explanations for the essentially zero attack rates are offered and discussed: peculiar motion of toroids or some unknown wall effect; rotational hydrodynamic forces cushioning the particle impact; the bed was not in suspension and not sliding over the walls of the toroid; round particles are not as erosive to oxide film surface as sharp pointed particles.
