Smokeless Powder

 

a low explosive whose basic component is nitrocellulose, plasticized by one of several organic solvents. Smokeless powder is a hard, corniculate substance, similar to plastic; it is manufactured in the form of so-called powder elements—disks, tapes, grains, tubes, and so on. It is very durable and can burn steadily without blowing up under high pressure (tens or hundreds of meganewtons per sq m—that is, hundreds or thousands of kilogram-force per sq cm). The basic types of smokeless powder are ballistite, cordite, and pyroxylin powders; they differ mainly in the technology of production, in the solvents used, and in the kind of nitrocellulose. Smokeless powder is significantly superior to black powder in its burning stability and efficiency. It is used in all types of firearms, in rocket engines using solid fuel, and for other purposes. The first smokeless powder—pyroxylin powder—was invented in 1884 by the French engineer P. Vieille.

Examples of double-base propellants are nearly the entire Alliant line, the IMR Enduran line, Norma propellants and Vihtavouri's 500 series.
Application of this production technique tc the Hodgdon Extreme line, IMR Enduran line and the newer Alliant propellants such as RL 16, 23, 26 and 33 have resulted in single- and double-base propellants that have little to no performance change with temperature.
