Burn-Rate Modifiers for DB Propellants

It can be seen from Table 4.10 that various compounds of lead impart high catalyzing influence on the burn rate of medium and high energy DB rocket propellants. 

Depending on their content, these compounds increase the burn rate of the propellants and in addition, decrease the burn-rate dependence on pressure and initial temperature of the propellant. Further, the influence of lead compounds on 

Lead compounds For the first time, Avery et al. observed the unusual behavior of lead compounds on ballistics of DB propellants [234]. 

Lead salts of aliphatic acids Burning characteristics remain substantially unaffected by variations in pressure during operation. Such propellants are suitable for use in rockets and guided missiles [235]. 

Oxides of lead, basic lead stearate, lead-2-ethyl hexoate, basic lead salicylate Render the bum rate of DB rocket propellants independent of pressure over a certain pressure range [236]. Such salts are effective only with cooler propellants i.e., cal. val. below -850calgT
