Destruction of a surface layer of nitroglycerin powder under ignition with different initial temperatures

Abstract

Surface destruction of the nitroglycerin powder at the initial stage of its ignition was experimentally detected. It is demonstrated that the destruction extent depends on the power of the external source, on the initial temperature and exposure time. A model of solid fuel ignition is proposed, which takes into account origination of stresses and deformations in the surface layer upon initiation of a chemical reaction. The ignition characteristics and the destruction extent are evaluated. The results obtained are in qualitative agreement with the experimental data.
