COATING VITON ON FLAKE ALUMINUM AND ITS EFFECTS ON PERFORMANCE OF THE SOLID ROCKET MOTOR
SINOPSIS
Aluminum powder is used as an additive in composite propellants to increase the specific impulse. However, the use of aluminum increases the two-phase losses and slag formation in the rocket motor. This study uses Viton as a coating for the aluminum powder for enhancing its reactivity to overcome these drawbacks. Viton-coated aluminum powder exhibited an enhanced reactivity over the uncoated powder. This Viton-coated aluminum demonstrated an increase of around 25% in the burn rates compared to uncoated aluminum when used in the composite solid propellant. The end mix viscosity of the propellant mixture remains constant with the prolonged mixing with the use of Viton compared to an increased viscosity observed with polytetrafluoroethylene as an additive.
