【 摘 要 】

The combustion characteristics of binarycompositions of fast-burning energetic materials (FBEM) with maincomposite propellant components like ammonium perchlorate (AP) andpolymeric binders have been studied in a constant pressure bomb, andcombustion mechanism has been proposed. Combustion behaviour ofcomposite propellants containing granulated FBEM of different particlesizes has been investigated. FBEM additives as high as 40 per cent offine particle size to a composite propellant have not been shown toinfluence markedly the burning rate, whereas incorporation of FBEMgrains of 500 micrometer particle size allows not only a considerableincrease in the burning rate but also modifies the burning rate-pressuredependence. A mechanism of combustion of propellant compositionscontaining FBEM grains has been evolved that allows criteria for FBEMperformance and combustion stability.
