An Innovative Strategy for Paraffin-Based Fuels Reinforcement: Part II, Ballistic Characterization
Abstract
Low regression rate is nowadays the main issue of hybrid rocket engines (HREs). The exploitation of paraffin-based fuels could be the answer to this problem. In the present study, ballistic behavior of HTPB and paraffin-based fuel blends are studied and compared with the one of the armored grains, new generation of fuels featuring 3D-printed cellular structures embedded in the paraffin grain. Regression rate measurements are performed by means of thickness over time (TOT) approach. Armored grain combustion performance makes this novel fuel an interesting candidate for high-performance hybrid rockets.
