The Hugoniots of M-30 Propellant and an Inert Simulator of M-30
Abstract
There was a need for the equation of state of porous propellant so that code calculations could be made to predict the response of propellant beds to shock pressures of varying intensity and duration. The work reported here is related to the XM1 Compartmentalization Study. One threat to crew and tank is propellant initiation caused by shaped charge jet penetration. What shock pressure conditions will be produced in the propellant bed during shaped charge penetration? Will the propellant reaction under these conditions to be so violent that quick venting is not possible? In order to answer these questions, it is helpful to know the shock Hugoniot of the impacted material. The work reported here was specifically directed toward the measurement of the shock Hugoniots for live and inert propellants and calculation of the shock Hugoniots of porous beds of these materials. The live propellant material is the seven perforation M-3- propellant which is used in the 105-mm APDS and HEAT rounds. The inert propellant consists of a thermoplastic material which has been extruded to the same configuration as the live propellant and has approximately the same density. The Hugoniots of M-30 and an inert simulator of M-30 have been determined by shock velocity measurements in samples of these materials. Also, porous Hugoniots for both materials were calculated using the solid Hugoniot and the Mie-Gruneisen equation. A knowledge of the porous Hugoniot is important in predicting the response of a propellant bed to a shock wave.
