Abstract
The burning of nitroglycerine-based propellants N and NB under unsteady conditions, when the sample burns pressed to a heat conducting lateral wall or placed onto a heat conducting substrate, was studied. The experimental results were analyzed within the framework of the concept of the existence of tangential waves that propagate over the burning surface, giving rise to chaotically migrating burning spots. The dependences of the unburnt propellant layer thickness on the thermal activity of the wall material and on the burning rate were obtained.
