Research of operating
pressure levels with irregular combustion and the effect on
combustion instability of composite solid propellants with different
quantity of octogen (HMX) are presented in this paper. The content
of HMX increased in relation to the oxidant, ammonium perchlorate
(AP). Combustion stability of the propellants was improved by adding
titanium (IV) oxide powder and through the optimal projected ratio
of two oxidizer fractions. Parameters of burning rate laws were
determined and p-t diagrams were observed and compared.
Key words: Composite solid propellant, octogen, ballistic behaviour,
combustion instability
