Abstract

Solid rocket fuels with a low pressure exponent and with little or no sigure comprise high-energy nitramine compounds in an amount of 50-90% by weight, an azide group-containing, high-energy binder system of polymers and plasticizers in an amount of 8-50% by weight and heavy metal catalysts in the form of lead, tin or copper compounds in an amount of 0.5 to 10% by weight.
