Description

technical field [0001] The invention relates to the field of solid propellants, in particular to an electronically controlled combustion solid propellant and a preparation method thereof. Background technique [0002] In the propulsion system, the gas production rate is one of the performance indicators of the propellant, and a high gas production rate can effectively improve the propulsion power of the propulsion system. High gas production propellants are widely used in rocket propellant systems, gas generators, oil field application development, airbags, and devices that require rapid gas production. [0003] With the development of modern industrial technology, high requirements are put forward for the performance control of the ignition, combustion and extinguishment of the propellant system. The precise regulation of electronically controlled combustion propellants can better meet people's needs. [0004] In modern military development, propellants with low signal ch...
