Scavenged AP propellant

Thus, the number of HCI molecules is reduced when sodium nitrate particles are incorporated into AP propellants. This class of propellants is termed scavenged propellants . Fig. 12.18 shows the results of thermal equibbrium computations of scavenged AP propellants as a function of the mass fraction of sodium nitrate.
