The negative impacts on flight safety caused by wing resonance problems are supported by previously reported aircraft accidents. The frequencies of the dominant vibrations generated by the Rotax-912 boxer engine, frequently used in short-wing UAVs and ultralight aircraft, particularly during climb, cruise, and descent phases, were determined. Mathematical mesh models were created for six different wing models, varying according to rib count and the position of the lateral strut under the wing. The natural frequency values of the wing models were determined using the finite element method and modal analysis for four different mode shapes. These values were compared with the vibration frequency values generated by the engine to interpret the wing's tendency to resonate. The suitability of each wing model for this vibration condition was discussed. Furthermore, to predict the risks that may arise in case of wing resonance, wingtip deformation and von-Misses stress values at different mode frequencies were determined and compared according to model types. This study is useful for UAV or ultralight designers whose aircraft are small enough to be transported in standard containers, as it helps them predict the effects that vibrations can have on the wings.
