One-dimensional, high-speed air flow characteristics are tabulated herein, Stagnatioa pressure and temperature; density ratio across a normal shock wave; and Mach number, static pressure and temperature, and stagnation pressure and temperature behind a normal shock wave are tabulated for several sets of given conditions which are free-stream Mach number and static pressure and temperature. The Beattie-Bridgeman equation of state, widely accepted as one of the best, empirical, pres¬sure-temperature-density relationships for air, is used in the calcula¬tions. The equation includes the effects of molecular vibrational energy which become important for high speed flows; the neglect of these effects in perfect gas law tables leads to considerable errors, even when so-called correction factors are included, The tables herein cover the range of flight and wind tunnel conditions wherein the vibra¬tional effects are important but before dissociation effects become important.
