Abstract : The theory is discussed which is basic to the understanding of the Newtonian impact theory and high-speed, high-altitude aerodynamics. Curves are presented for cones with semicone angles from 10 to 20 degrees in increments of 1 degree plotted with the various aerodynamic coefficients against cone angle of attack (from 0 to 15 degrees). A computer listing of the program which generated these curves is also presented. Curves are provided which can be used in most ICBM trajectory programs which utilize cone-shaped reentry vehicles. Other shapes can be utilized based on the theory presented but only the cone has been developed in this report. (Author)
