Increasing the critical pressure of composite propellants by admixing into he propellant composition an additive selected from the group consisting of (1) oxides of Group II metals, titanium, aluminum, boron, zirconium, and lead; (2) nitrides of Group II metals, aluminum, and boron; (3) carboxylates, formates, and sulfates of Group II metals, aluminum, calcium, and magnesium; (4) hydrates of the carboxylates, formates, and sulfates of Group II metals, aluminum, calcium, and magnesium; (5) the following fibrous materials, asbestos, quartz, carbon, and boron; (6) the following metal: Group II metals and boron; and (7) mixtures thereof.

Composite propellants containing critical pressure increasing additives

Cooled gas generating solid propellant, includes sodium azide or lithium de as a nitrogen gas source, a fluorocarbon binder material, a combustion catalyst, and alkaline metal acid salt coolant.

Coolant additives for nitrogen generating solid propellants

A submersible object having a drag reducing coating thereon, and a method r its preparation, which comprises applying to the object a binding agent and sufficient hydrophobic silica to provide the object with a nonuniform coating, the function of the binding agent being merely to fix the hydrophobic silica on the submersible object.

Submersible object having drag reduction and method

High impetus, low flame temperature propellants are produced by the incoration of a polynitramine into a saturated polymer of a lower hydrocarbon.
