Theoretical, qualitative and quantitative analysis of annular detonation wave parameters are carried out. In accordance to the theory of detonation optics, the chemical reaction zone is replaced by surface of strong discontinuity. This surface is termed the detonation wave front. It was found that in the upper layer of the cylindrical charge (more than 0.5r0 thick the explosive gas mixture) the annular detonation wave propagates with velocity comparable to the Chapman-Jouguet velocity, and its front is similar to the half-tours surface. The radial cumulation of the annular detonation wave parameters occurs in the direct neighborhood of the charge axis. All the parameters, except of the specific volume, increase to infinity when the charge radius decreases to zero. The phenomena of the dissociation and ionization of detonation product in the cumulation state have been neglected, therefore the results obtained in the direct neighbourhood of the charge axis have a qualitative character.
