Claims13
In a propellant comprising a nitrocellulose-containing binder, and an oxidizer, the improvement comprising including as a component of the propellant at least one lead fluoride selected from a formula of the group consisting of PbF.sub.2 and PbF.sub.4.
In a propellant comprising a binder, and an oxidizer, the improvement comprising including as a component of the propellant at least one lead fluoride selected from a formula of the group consisting of PbF.sub.2 and PbF.sub.4, wherein the lead fluoride comprises 17% to 26% by weight of the propellant.
In a propellant composition selected from the group consisting of double base propellants and composite modified double base propellants wherein the improvement comprises the addition to the propellant composition of a lead salt selected from the group consisting of PbF.sub.2 and PbF.sub.4 and mixtures thereof, wherein the lead salt is present in an amount between 5 and 45% by weight based on the total weight of the propellant composition.
An improved composite modified double base propellant composition wherein the improvement comprises the addition to the propellant composition of a lead salt selected from the group consisting of PbF.sub.2 and PbF.sub.4 and mixtures thereof, wherein the lead salt is present in an amount between 5 and 45% by weight based on the total weight of the propellant composition.
