Abstract : Small amounts of metal tetrahydridoborohydrides, e.g. as low 1% by weight of the nitramine, are effective for increasing the burning rate of nitramine propellants. Excellent results can be obtained by employing the metal tetrahydridoborohydrides in an amount of about 10% by weight of the nitramine component, whereby burning rates several times higher than that obtained with the unmodified propellant are obtained. Amounts of such metal tetrahydridoborohydrides up to 20% or more by weight of the nitramine are also effective to increase the burning rate of nitramine propellants; however, the use of such larger amounts is less desirable since it reduces the proportion of nitramine and hence the enrgy output of the propellant.
