Constraint-driven aero-structural twist optimization of 3D-Printed PETG low-Reynolds-number multirotor propellers
Flexible fused-deposition-modelled propellers can lose endurance when deformation changes the designed incidence, while thin sections that appear aerodynamically superior may be structurally inadmissible. This study develops a constraint-driven aero-structural workflow for a 9.4 in two-bladed glycol-modified polyet...
