A novel high-performance “green” hybrid propulsion (HPGHP ) system has been developed as an environmentally sustainable replacement for hydrazine. HPGHP has been enabled by recent advances in 3D printing and leverages the unique electrical breakdown characteristics of certain printable plastic filaments. When the 3D-printed fuel materials are presented with an electrical potential, arcing occurs along the layered surface, pyrolyzing the material and allowing combustion. In its most mature form, HPGHP uses gaseous oxygen (GOX) as the oxidizer. To increase the HPGHP volumetric efficiency, a two-phase blend of nitrous oxide and oxygen, similar to laughing gas or Nytrox, has been engineered as a higher-density “drop-in” replacement.
