Smokeless propellants

Mass, Specific, of Constituents of Smokeless Propellant. Literature data on the specific mass of over 100 compds are given in Ref. Kopp s additive rule applies with an error generally less than 1%, eg, 1/d — 2 (nj/pj), where nj is % of constituent, pj is specific mass of constituent, and d is specific mass of propellant Ref P. Tavernier, MP 30, 253-96 (1957) CA 53, 1715-16 (1959)...

These double-base propellants are best known as smokeless propellants used in guns and rockets. Two major ingredients are used to formulate the double-base propellant grains NG and NG. As covered in Section 4.2.2, NG is a nitrate ester characterized by -O-NO2 groups, and is known as a high explosive. Since NG is a liquid at room temperature, it is absorbed by NG and serves to gelatinize the latter to form... 

Similar to nitramine composite propellants and TAGN composite propellants, AN composite propellants produce halogen-free combustion products and thus represent smokeless propellants. However, their ballistic properties are inferior to those of other composite propellants the burning rate is too low and the pressure exponent is too high to permit fabrication of rocket propellant grains. In addition, the mechanical properties of AN composite propellants vary with temperature due to the phase transitions of AN particles.
