Electron Density Behavior in the Wake of Spheres Flown at 14,500 Feet/ Second

Abstract

The amplitudes and widths of the assumed gaussian distributions of electron density in the wakes of hypersonic spheres flown at 14,500 feet/second in atmospheres of air and nitrogen at various pressures have been derived from phase shift measurements with a dual channel interferometer. The data apply to the near wake extending from just behind the spherical projectile out to several hundreds of body diameters.
