On Calculating Ignition of a Propellant Bed.

Abstract

Various criteria for ignition of solid propellants are considered for use in gun ballistics calculations. Experimental data are examined and extrapolated for use in the NOVA computer code. DeLuca's laser ignition data are considered most applicable. Calculated flamespreading rates with a surface temperature criterion agree better with measured rates than those calculated with ignition delay criteria from radiant flux experiments. Goodman's integral method is shown satisfactory for use in a linearly rising heat flux. (Author)
