Abstract
The present invention relates to solid propellants with high specific impulse and/or high impulse per unit volume, more particularly so-called 'clean' propellants, that is to say containing no constituents whose combustion gives halogen-containing products or liquid or solid products. The solid propellants according to the invention comprise especially a binder, at least one energetic filler and various additives; the energetic filler is chosen essentially from the group of dinitrated bifurazanes consisting of 3,3'-azoxybis (4-nitrofurazane), 3,3'-azobis(4-nitrofurazane) and 3,3'-bis(4-nitrofurazane).
