On the Possibility of High Velocity Deflagration Front Propagation by Radiative Energy Transfer
Abstract
Flash x ray data of the burning of Hivelite, a proprietary material made by McCormick Selph Teledyne Company, indicates a burning velocity of (about) 383 m/s. Since this exceeds the velocity of deflagration arising from thermal conduction initiation and falls below the value of detonation velocities which arise from shock propagation and thus exceed a material's sound velocity, the existence of a distinct ignition wave front propagation mechanism is to be considered for this material. A new mechanism of ignition front propagation that depends on IR radiation transmission into a highly IR transparent flame sensitive material is proposed and formulated. Present data for the properties of Hivelite are not complete enough to determine if its burning rate arises from an ignition wave of the type treated here, but the present data is compatible with that interpretation. Keywords: Radiative ignition wave, Detonation velocity, Infrared radiation, Propellant burning rate, Hivelite.
