Many equivalent names for the same propellant can be found in the literature (or in this book); besides that the French have developed a specific terminology for composite and high-energy propellants which is described in Chapter 2, Section 3.2.1. This is probably due to the fact that authors sometimes refer to the chemical composition, sometimes to the production process and sometimes to some functional characteristics such as smoke or mechanical properties (e.g. elastomeric modified double-base). Homogeneous propellants are also called (surprisingly) double-base pro­pellants (based on nitrocellulose and a nitric ester). The two main types are extruded double-base or E D B (in French SD for "sans dissolvant", meaning without solvent) and cast double-base or C D B (in French Epictete!). When energetic solids are introduced into this propellant it becomes a C M D B , for composite modified double-base. This name is used only for cast propellants even if some EDBs can contain oxidizers or energetic solids. Elastomeric modified cast double-base or E M C D B propellants have been developed. They are cast double-base propellants in which an elastomeric binder has been added to the doubl
