Solid propellant processing techniques

Gel propellants can be considered as a separate category of liquid propellant technology. They provide a unique application of solid propellant processing techniques and materi-...

Then a final apparently steady, deton was established at 8280 m/sec 4) Skidmore Hart (Bet 88) produced overdriven detonation waves in Comp B carrying increased velocities and pressures up to twice the C-J pressure by an explosive driven plate impact technique. The basis of the technique is to explosively propel a metal driver plat e at a similar target plate on which rests a sample layer of expl backed by a further layer of inert solid. When the driver plate vel is sufficiently high this process generates a steady overdriven deton wave in the expl unless (or until) it is overtaken by the rarefaction wave from the rear of the driver plate. 

Later on, a number of patents were filed (158-165) that described techniques for spraying different compounds onto various substrates. In these processes the solid of interest is suspended in a liquid carrier, and a compressed gas is added to the suspension. Then, the mixture is sprayed onto the surface to be coated. In some cases the compressed gas plays two roles, acting as a propellant and also as a solvent. Most of these processes were patented by... 

Probably the most important characteristic of military and commercial explosives and solid rocket propellants is performance as related to end use and safety. Performance can be described by a variety of conventional properties such as thermal stability, shock sensitivity, friction sensitivity, explosive power, burning, or detonation rate, and so on. Thermal analysis methods, according to Maycock (51), show great promise for providing information on both these conventional properties and other parameters of explosive and propellant systems. The thermal properties have been determined mainly by TG and DTA techniques and isothermal or adiabatic constant-volume decomposition. Physical processes in pseudostable ma-...
