摘要：

We present results of an experimental study of burning of a ballistite solid propellant (gun powder Ii) in a supersonic how. It is shown that the criterial dependence of the erosion coefficient on the Vilyunov parameter obtained on the basis of experimental results in a subsonic and a supersonic how describes satisfactorily experimental data for a supersonic flow in the examined range of Mach numbers M = 1-2.8 as well. A more correct approximation formula for the range of parameters considered is derived. The specific features of the how along the surface of a solid propellant at M > 1 is analyzed, and this analysis has revealed some problems in the interpretation of experimental data.
