Abstract
The results of the study of metal particles combustion process in free fall in air are presented. Titanium particles with a size of 120-540 microns and particles-aluminum agglomerates with a size of 540-660 microns were used. The characteristic times of the beginning and the end of fragmentation, the end of combustion were found with help of video filming. The laws of particles motion, in particular, their velocity and coordinate at the moment of the beginning of fragmentation, were determined. The size of titanium particles at which the fragmentation mode changes (“star” and “spruce branch”) were estimated. Condensed combustion products of particles were selected and investigated.
