Cryogenic propellants examples

Clearly, this technique may have application to a widening variety of systems that involve exploding materials, such as propellants, laser-heated materials, electrically heated materials, and materials that are simply shock heated. For example, propellant bum chemistry might be quenched at a desired point in the bum process by firing the propellant in a container sealed with a suitable burstable diaphragm properly aimed at the skimmer. The technique has even been applied to cryogenically prepared samples of energetic materials (7,8). 

During the last decade, the tremendous strides taken in the exploration and exploitation of space have placed new environmental demands on the engineering use of elastomers. In particular, the use of rubber polymers in cryogenic and space applications (in the binder of some solid rocket propellants and in low temperature seals, for example) requires that rubber withstand extremely low temperatures. Under these conditions, rubber can become brittle and cracks can propagate easily through the material. In the case of solid rocket propellants, these cracks can lead to uneven and uncontrolled burning. As one practical technique for increasing...
