Abstract
The combustion of 12 composite propellants of the following composition was studied: 60% ammonium perchlorate of the sieve fraction (180-250 μ m)-20% active combustible binder- 20% titanium of different particle size and nature (with spongy particles of size d =32-71 μ m and with rolled pseudospherical particles of size d = 71-500 μ m). Burning rates and agglomeration parameters of the metal component at pressures 0.35 MPa in nitrogen and 0.1 MPa in air were determined. It has been found that agglomerates with minimal sizes are formed when using titanium powders with particles of the smallest sizes.
