The influence of angular velocity on the light output, slag retention, and burning rate of magnesiumstrontium nitrate pyrotechnic compositions consolidated into metal cavities is discussed. Stoichiometric, as well as, non-stoichiometric fueloxidizer mixtures were studied at rotational speeds up to 43,000 rpm and a parametric burning-rate equation was developed. In addition, qualitative descriptions of the burning phenomena and its effects are presented.
