Very Fast Burning Cordites
Abstract
Work has been carried out at ERDE on double-base propellants containing lead beta-resorcylate and basic cupric salicylate to which carbon blacks have been added. For most of the work the standard solventless process was used; the fastest platonised burning rates were obtained with a carbon black, and one formulation, F488/1827, burning at 41 mm/s at pressures between 17 and 34 MN/sq m has been the subject for development trials. At lower calorimetric values, slower burning rates were obtained, but platonisation could be extended to pressures of at least 45 MN/sq m or to 51 MN/sq m by changing to low nitrogen content nitrocellulose. Replacement of some nitrodiphenylamine by resorcinol gave further increases in burning rate. Attempts to increase burning rates by activation of the carbon black and charcoal were not successful and similar burning rates were obtained with somewhat larger amounts of untreated carbon black. Solvent processed versions of some promising fast burning formulations for use in thin web sizes were satisfactorily tested.
