Abstract

Solid composite propellant compositions include at least one fuel, at least one oxidizing agent, at least one binder, and at least one sufactant. The surfactant provides the solid propellant the property of being "self-extinguishing", where the burning rate of the solid composite propellant as a function of pressure includes a negative pressure dependent on portion, wherein the burning rate in the negative pressure dependence portion decreases with increasing pressure until a cutoff pressure is reached which results in extinguishment of the solid composite propellant. The solid composite propellant can also include at least one catalyst that modifies the burning rate of the solid composite propellant. Solid composite propellants according to embodiments of the invention can be extinguished without the need of depressurization by reaching a cutoff pressure, and with a tailored burning rate.
