Recent technological advancements in unmanned aerial vehicles have led to their use various military and civilian applications. However, weather conditions, operator faults, electronic or mechanical problems can result vehicle accidents. In the event of an accident, energy-absorbing structures be placed specific regions protect sensitive costly cameras, sensors, cargo from damage, while also preserving vehicle's structural integrity. this study, thin-walled energy absorbers with circular, square, hexagonal, reentrant geometries were proposed, experimental investigation focused on effect increasing number cells crashworthiness performance deformation mechanisms. Lateral compressive load was applied produced by fused deposition modeling technology using advanced polylactic acid filament. Experimental results showed that triple-cell structure demonstrated promising for applications, as it exhibited highest mean crushing force, absorption, absorption values. Thanks unique geometry structure, a gradual collapse mode observed, result, high performance.
