Numerical modal analysis of the CL-215 Bombardier’s tail

Abstract

Forest fires pose a global threat, and the operational safety and performance of firefighting aircraft are of critical importance. Structural vibrations in CL-215 Bombardier aircraft operating under ground effect and challenging geographical conditions may adversely affect flight safety and mission effectiveness. The purpose of this study is to analyze the dynamic behavior of the CL-215 Bombardier aircraft tail structure to determine critical vibration frequencies and evaluate the effects of structural deformations. Using numerical modal analysis methodology, CAD design was created with SpaceClaim 2025 R2, while meshing and analysis were performed on the Workbench 2025 R2 platform. This study represents one of the first comprehensive investigations providing detailed modal analysis for the CL-215 tail structure. The analysis results demonstrate that the tail structure resonates at six different critical frequencies, reaching a maximum deformation of 0.24727 mm. The obtained findings provide valuable data for predicting potential vibration problems in the tail structure during firefighting operations, optimizing structural safety parameters, and future design improvements. The results of this study will contribute to enhancing the operational safety of firefighting aircraft and developing more effective fire suppression strategies. This research fills a significant gap in the literature by providing the first detailed modal characterization of the CL-215 tail assembly, offering essential insights for aerospace engineers and aircraft designers working on amphibious firefighting aircraft optimization.
