Abstract : An improved pyrotechnic composition having a metal pyrotechnic fuel and an oxidizer for producing light, heat, smoke and sound from an exothermic reaction wherein the improvement comprises the use of a metal hydride as the pyrotechnic fuel to provide rapid ignition and reduced burning rates with high metal content for increased luminous efficiency. The metal hydride fuels are selected from groups consisting of magnesium hydride (MgH2), titanium hydride (TiH2), lithium aluminum hydride (LiAlH4) and sodium borohydride (NaBH4). The principal object of this invention is to provide an improved pyrotechnic composition of increased luminous efficiency which is easier to ignite and which has a reduced pyrotechnic burning rate with high metal content. It is another object of this invention to provide an improved pyrotechnic fuel comprising a metal hydride for use in artillery, tank cannon and small arms projectiles. It is a further object of this invention to provide an improved pyrotechnic fuel ingredient for use in rocket motor igniters to provide more reliable ignition than conventional known based igniters. It is a still further object of this invention to provide an improved pyrotechnic fuel mix for use in the base of projectiles as 'fumers' or 'based-bleed' materials to reduce the projectile's base drag for easier ignition and higher specific impulse than conventional fuel mixes. It is another object of this invention for an improved fuel for use in solid fuel ramjet for easier ignition and higher specific impulse than conventional magnesium based fuels.
