COMBUSTION INSTABILITY OF SOLID PROPELLENTS: EFFECT OF OXIDIZER PARTICLE SIZE, OXIDIZER/FUEL RATIO AND ADDITION OF TITANIUM DIOXIDE TO PLASTIC PROPELLANTS

Abstract

The effect of variations in the composition of solid propellents on their tendency to show combustion instability at 1000 psi has been investigated using a T burner. It has been shown that ammonium perchlorate particle size can have a large effect on the acoustic response and that this is frequency- dependent. Titanium dioxide is usually added to plastic propellents to promote stable combustion and the mechanism of its action has been determined. With a view to the potential use of oxygen-balanced propellents the effect of varying the oxidizer/fuel ratio of plastic propellents has also been studied.
