| Abstract Scope |
Ammonium perchlorate composite rocket propellant (APCP) is a commonly used solid propellant in commercial and defense applications. Current solid rocket motors are manufactured through a propellant casting process, which has high associated costs and imposes limitations on the internal structure and composition of the motor. In the present work, an APCP propellant designed for additive manufacture is characterized in terms of viscosity and yield stress of the non-Newtonian uncured material, as well as the final product’s layer-bonding behavior and combustion performance. Spindle and extrusion-based viscometry methods are used to examine the uncured material, while microscopy and tensile testing are employed for the analysis of the cured structure. Combustion behavior is quantified using a strand-burning apparatus. Properties of the final product are compared to tabulated structural and combustion ranges for APCP, and the applications for the material are discussed. |
