Properties of an equilibrium detonation model

A shock wave of zero width is studied as a detonation model in the case when detonation products are in chemical equilibrium behind this shock wave. Together with the well-known properties, some new properties of this model are found. In particular, it is found that there exist weak and strong self-sustaining detonation waves; the latter one propagates in the Chapman-Jouguet regime and corresponds to the point of contact of the Mikhelson line with a new-type adiabat called the extreme adiabat.
