Abstract
Environmentally friendly high performance minimum signature propellants have been demonstrated for use in next generation tactical missile applications. Bismuth salicylate and bismuth citrate have each been used in propellant formulations and evaluated for processing, ballistic, mechanical, aging and signature properties. These high performance formulations have potential to replace current formulations used in some fielded tactical systems. The propellant binder network is achieved using energetic nitramine polymers where inert polymers have been the polymer of choice for minimum signature propellants. The significance of this has to do with achieving propellant specific impulses greater than 245 seconds without nitroglycerin being used in the formulation. This improves propellant safety properties during the propellant processing and the manufacturing of the final missile configurations. The Army has mandated that the next generation propellant formulations show improvements in safety to the end users. These formulations are environmentally friendly (no-lead) and do not use nitroglycerin to achieve high performance.
