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.
