Theoretical, qualitative and quantitative analysis of annular detonation wave parameters is carried out. In accordance with the theory of detonation optics, the chemical reaction zone is replaced by the surface of strong discontinuity. This surface is termed the detonation wave front. It was found that in the upper layer of the cylindrical charge, the annular detonation wave propagates with a velocity comparable to the Chapman-Jouguet velocity, and its front is similar to the half-toroidal surface. The radial cumulation of the annular detonation wave parameters occurs in the direct neighbourhood of the charge axis. All the parameters, except for 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 are of a qualitative character.
