In this paper we study the control of vibrations of a HALE aircraft wing using TMD devices. The structure was modeled using a commercial structural analysis software. The wing profile and material characteristics used were provided in available literature. Aerodynamic loads of random nature are simulated. When the first natural frequencies of the structure are close to the aerodynamic loads frequencies it can lead to unsafe flying conditions due to resonance. In addition, it can shorten the frame life due to material fatigue and further maintenance may be required. Processing suggests the presence of accelerations above the desired or anticipated by several international standards on the subject. To mitigate them, passive vibration absorber (TMD's, Tuned Mass Dampers) control is proposed for vertical and lateral vibrations.
