Cast double base propellant composition

The composition of various more modern cast double base propellants (according to Sutton [56] and J. Taylor [57] is shown in Table 194. Table 195 gives the physico-chemical properties of propellant I. 

During the past 10 years great strides have been made in the development and service application of highly loaded, synthetic rubber-base and interstitially-cast double-base composite-modified propellants. Largely for this reason and for economic and logistic reasons as well, the slurry-cast nitrocellulose plastisols have been relegated to a secondary role. 

Nitrocellulose is transported in tightly closed drums or in pasteboard drums lined with plastic bags inside, which contain at least 25% of a moisturizing agent (water, alcohol, isopropanol, butanol, etc.). Spherical NC particles are precipitated from solution under vigorous stirring, and preferably used for manufacturing of cast or composite double base propellants. 

Another substantial increase in delivered energy was obtained by incorporating substantial amounts of solid oxidizer e.g., ammonium perchlorate) and metallic fuel e.g., aluminum) in the casting powder. The resulting family of composite-modified double-base (CMDB) propellants has found widespread use in ballistic missiles and space motors.

Some information based on the description by Steiiiberger and Orechse [40] is given here. They give the composition of single base, double base and coiii-pi>sile cast propellants in Table 123.
