Approximate analytical relations are developed for several possible conical flow fields resulting from the steady supersonic flow of a uniform, non-viscous, non-heat conducting, combustible-gas mixture past a semi-infinite cone at zero angle of attack for instantaneous chemical reaction. The flow fields considery-are of the shock-deflagration, detonation, and detonation-shock types with attached adiabatic and diabatic discontinuities. Particular emphasis is placed upon the Chapman-Jouguet detonation. Parametric curves are presented for shock-deflagration flows about cones and wedges, and Chapman-Jouguet detonative flows about cones. Generalized analyses of the flow characteristics of an oblique exothermic discontinuity are given in the appendices.
