COMBUSTION OF COMPOSITE PROPELLANTS WITH TITANIUM

The combustion of 12 composite propellants of the following composition was studied: 60% ammonium perchlorate of the sieve fraction (180–250 m), 20% energetic binder, and 20% titanium particles of different sizes and types (spongy particles of size m and rolled pseudospherical particles of size m). The burning rates and agglomeration parameters of the metallic component at a pressure of 0.35 MPa in nitrogen and 0.1 MPa in air were determined. It was found that agglomerates of minimum size were formed when using titanium powder with minimum particles size.
