1. A pneumatic deicing system, comprising:
a deicing boot assembly, wherein the deicing boot assembly comprises a pneumatic deicing boot; and
a gas generator fluidly coupled to a pressure regulator of the deicing boot assembly and electrically coupled to a power supply, wherein the power supply is configured to send a first electric pulse into the gas generator, and wherein the gas generator comprises:
a propellant storage unit further comprising a sodium-based propellant, and
a combustion chamber further comprising an ignitor, the ignitor configured to contact the propellant and to supply a second electric pulse to the propellant, wherein the second electric pulse is configured to pass through the propellant, and
a residual collector coupled to the combustion chamber,
wherein the sodium-based propellant is configured to be transferred from the propellant storage unit to the combustion chamber, wherein the propellant is configured to decompose in response to the second electric pulse passing through the propellant, and wherein the decomposed propellant is configured to be liberated as a high pressure gas.
