Title: AEROELASTIC INVESTIGATION OF HINGELESS HELICOPTER ROTOR IN HOVER
Keywords: helicopter, aeroelasticity, aerodynamics, structural dynamic
Abstract: An aeroelastic modelling of pattern hingeless helicopter rotor in hover is presented in this paper. The coupled aeroelastic problem accounts for the mutual dependence between blade structure and rotor aerodynamics. The aerodynamic model uses Blade Element Momentum Theory (BEMT). BEMT gives good accuracy with respect to time cost. The structure model uses Finite Element Method (FEM). The investigation is based on the well-known solvers MATLAB and ANSYS. The obtained results show that the proposed modeling is efficient, rapid and gives reliable results. This modelling is also useful and applicable for airplane propellers, wind turbine rotors and airplane wings.
