Triaxial acceleration data from UAV propeller blades: pre- and post-small-scale tip fracture tests on a custom-built rig (raw signals) Xianfeng Wang (24557550) Aerospace engineering not elsewhere classified Mechanical engineering not elsewhere classified Unmanned aerial vehicle safety Structural health montoring (SHM) propeller blades tip fracture triaxial acceleration data <p dir="ltr">This dataset provides raw triaxial acceleration signals (unit: V) from UAV propeller blades tested on a custom-built rig suspended by flexible steel wire ropes. The sensitivities for the X, Y, and Z axes are 251.75 mV/g, 248.49 mV/g, and 249.90 mV/g, respectively, with the rotational speed held at approximately 3,220 RPM. The data are divided into two groups: Group 1 contains raw triaxial acceleration data from 18 healthy blades, while Group 2 includes remeasured raw triaxial acceleration data from 2 healthy blades (B-7 and B-13) and 5 blades with progressive tip fractures (2, 4, 6, 8, and 10 mm). This is because the damage evaluation was conducted at a separate time from the initial healthy blade tests. Due to mechanical relaxation of the steel wire ropes and environmental fluctuations, directly comparing Group 2 to the initial Group 1 would introduce systematic errors. Therefore, a dynamic re-baselining strategy was applied, using contemporaneous measurements of B-7 and B-13 to establish an updated reference spectrum.</p> 2026-09-21T14:00:29Z Dataset Dataset 10.6084/m9.figshare.33296838.v2 https://figshare.com/articles/dataset/Triaxial_acceleration_data_from_UAV_propeller_blades_pre-_and_post-small-scale_tip_fracture_tests_on_a_custom-built_rig_raw_signals_/33296838 CC BY 4.0
