High Density PolyEthylene (HDPE) is one of the possible solid fuels to be used in hybrid rocket propulsion, despite its low ability of rapidly producing combustible gas. This drawback may be balanced by the auto-ignition delay of the pyrolysis products, which would conduct to the increase of the hea...
