When formulating a new solid propellant, one of the most important aspects its performance is burning rate's response to change in pressure. For this reason, it useful be able predict rate given propellant before formulation created such that experimental trade studies are minimized or reduced scale. While many theoretical and phenomenological models have been proposed explain various energetic...

An effective biaxial tension and compression test method is proposed based on the shortcomings of current research for mechanical properties solid propellants under complex stress states. The equal proportion HTPB (Hydroxyl-terminated polybutadiene) NEPE (NitrateEster Plasticized Polyether) performed at different rates while room temperature, damage morphology tension–compression zone analyzed ...
