Abstract : Survey arrays of ion probes were used to study the structure of the ionized turbulent wakes of 2.7 in. diameter spheres flown at 14500 ft/s in atmospheres of nitrogen at pressures of 7.6 and 20 Torr. For various radial distances measured from the wake axis, matrices of data points were obtained giving random values of the axial distance behind the projectile at which ionization begins, the first ionized eddy occurs, and continuous turbulence begins.
