Notes:
Eli Ltd. and Tallinn University of Technology (TUT) Department of Mechatronics arecurrently performing studies in order to develop a mini-class universal purpose unmanned aircraft[1,2]. The paper focuses on strength calculations and weight vs. strength optimization of thefuselage of this developed UAV system. To develop a strong but lightweight UAV fuselage,advanced computer modeling and finite element structure analysis are used as virtual prototypingtools for the optimization of the fuselage at early design stage and through the production period toimprove the design [3]. Design optimization is applied to minimize the maximum stresses withinthe fuselage, subject to strain constraint in conjunction with both geometry and choice ofappropriate fibre orientations and stacking sequence as design variables and also materialparameters. The fuselage for the UAV plane was designed and manufactured using E-Glass/Epoxyand High modulus (HM) carbon/Epoxy composites. In this paper ANSYS software has beensuccessfully applied to minimize the weight of the fuselage and increase the UAV fuselage strength.The results show how the fuselage design could be improved with the help of finite element methodanalysis and provide guidelines for the structure and material design for the composite based UAVSWAN fuselage
