Abstract
Influence of the composition of pyrotechnic mixtures based on organic fuel (ascorbic acid) on the burn rate, heat of combustion and ignition temperature was examined. Results have shown that all of the tested mixtures meet the quality requirements for application as gas generators for Base Bleed projectiles. The composition of the pyrotechnic mixture with the highest values of heat of combustion and burn rate and the lowest ignition temperature is selected as the most suitable for this application.
Highlights
FIRING ability of military units in field increases with the increase of missile range of the Conventional ammunition, which gives priority to the first attack and provides additional time for proper grouping and better organization of defense or attack.The resistance that occurs during the flight of projectiles through air affects the reduction of its range
Initial tests, carried out on the gas generator (GG) units for 37 mm projectile (Fig.1), have shown that the mixture, with magnesium as a fuel component, gives very high heat of combustion and that during its combustion it released significant amounts of solid and liquid products of combustion. These characteristics of combustion are the advantage of using this mixture for safe ignition composite solid propellant, but it could be a serious drawback to its use in the GG unit Base Bleed projectiles if we take into account the requirements that charging GG unit must satisfy [5,6]
This paper presents the optimization of the composition of pyrotechnic mixture, based on ascorbic acid as an organic fuel for production of gas generators charges for base bleed projectiles
Summary
FIRING ability of military units in field increases with the increase of missile range of the Conventional ammunition , which gives priority to the first attack and provides additional time for proper grouping and better organization of defense or attack. Initial tests, carried out on the GG units for 37 mm projectile (Fig.1), have shown that the mixture, with magnesium as a fuel component, gives very high heat of combustion (there have been melted edges of the aluminum cylinder in which the mixture was pressed) and that during its combustion it released significant amounts of solid and liquid products of combustion These characteristics of combustion are the advantage of using this mixture for safe ignition composite solid propellant, but it could be a serious drawback to its use in the GG unit Base Bleed projectiles if we take into account the requirements that charging GG unit must satisfy [5,6]. 22 PETKOVIĆ,C.J., etc.: PYROTECHNIC MIXTURES FOR PRODUCTION OF GAS GENERATOR CHARGES FOR BASE BLEED PROJECTILES BASED
