Traditional hybrid rocket fuel can improve fuel combustion efficiency through structural design which is conducive to aerodynamic enhancement of regression rate. However, complex structure increases the difficulty of fuel structure forming, hindering the scientific research and engineering application verification of fuel charge with heterogeneous and topological structure in the hybrid rocket. 3D printing is used to manufacture hybrid rocket fuel grains with a special mesh structure to improve combustion performance. \!hen analyzing the gas-phase and solid-phase combustion characteristics of acrylonitrile­butadiene-styrene (ABS) fuel with a single-hole mesh structure, the penetrative combustion phenomenon of 3D printed structural fuel was first discovered, and the minimum print infill density of fuel charge axisymmetric ring disintegration caused by penetrative combustion was determined. The results show that penetrative combustion can effectively increase the regression rate.
