THE COMBUSTION MECHANISM FOR AIR AUGMENTED ROCKET PROPELLANTS CONTAINING ELEMENTAL BORON
Аннотация
Elemental boron is extremely attractive as a fuel additive for propellants burning with air. This
paper presents the results of an analytical and experimental study of the combustion of boron in a solid
propellant. A combustion mechanism is proposed for a boron containing air augmented propellant based upon
conductive, convective, and radiant heat transfer between the propellant constituents and their combustion
products. Qualitative experimental data supports the proposed mechanism. This study indicates
that boron will burn only if its particle size is extremely small or the combustion temperature is high.
