摘要

A set of 19-perforation propellants containing triethyleneglycol dinitrate (TEGDN) withdifferent length/outside diameter ratios and perforation diameters was prepared and tested ina closed vessel to investigate their burning progressivity. The influence of length/outsidediameter ratios and perforation diameters on the progressive combustion performance isstudied through the dynamic vivacity method. With an increasing of the length/outsiderdiameter, the silvering point occurs earlier and longer and the burning progressivity ofsurface area can be improved. For propellants with same length/outside diameter ratio, witha decreasing of perforation diameter, the slivering point lags behind and the burningprogressivity becomes greater. The silvering point corresponds to the instantaneous burningarea which is related to the form function and silvering process. However, the total burningprogressivity of propellant is a very comprehensive result of propellant under multipleactions, including the mass fraction of burnt propellant, grain size and burning rate atdifferent pressure regions. The correlation between them can boost a better understandingon the interaction between grain size, silvering burning process and burning progressivity.
