Reverse Engineering and Metrological Validation of Aircraft Fuselage Components: Experimental Insights from the NEMESI Project

연구 분야: Analysis

학회: 2025 IEEE 12th International Workshop on Metrology for AeroSpace (MetroAeroSpace)

This study, conducted under the NEMESI (New Engineering & Manufacturing Enhanced System Innovation) project, integrates reverse engineering and metrological validation of ATR aerospace components, focusing on a cargo door (RFQ 1–8) and fuselage interfaces (Section 11). Using the Leica AT960-LR Laser Tracker (SN 750843) and LAS (SN 745283), we analyzed RFQ 7, RFQ 8, and Section 11 (Upper Lobe, Lower Lobe AFT, Lower Lobe FWD). Local precision reaches RMS errors of 0.14 mm, but outliers peak at 60.43 mm (Lower Lobe AFT). Tolerance compliance ranges from 6.8% (Upper Lobe) to 70% (RFQ 8 hinge stops). These results highlight challenges in achieving stringent tolerances, informing quality enhancement strategies.
