Abstract
A fumer exhibiting reduced base drag and a high specific impulse is provided by using as the pyrotechnic charge in the projectile a composition comprising a metal powder/alkaline earth metal compound formulation containing at least about 20 percent by weight of a plasticized resin and at least about 10 percent by weight of an active oxidizer for said resin. The metal powder is present in greater than stoichiometric amounts relative to the amount of alkaline earth metal compound and the pyrotechnic composition is effective to provide rapid burning in the near wake area of the projectile and fuel-rich combustion products.
