초록

In this method for making multi-base propellants, pelletized nitrocellulose is coated with an electrostatically insensitive liquid elastomer precursor or non-plasticizer while wetted in a non-solvent diluent, preferably in the absence of plasticizers. The non-solvent diluent is then substantially, if not completely, removed from the coated nitrocellulose. Then, the coated pelletized nitrocellulose is mixed with a plasticizer and optionally other ingredients and fillers, including energetic fuels such as nitroguanidine. The propellant formulation is then ...
