Static Aeroelastic Analysis of Electric Vertical Takeoff and Landing Aircraft ET480

This paper presents the static aeroelastic analysis of the electric vertical takeoff and landing aircraft (eVTOL) ET480 by using the inner-house code AeLasV2.0.4. Firstly, the structure modeling of complete configuration for this type of eVTOL are implemented by using the geometrical nonlinear beam elements. The structural deformations are then predicted according to this finite element model. Secondly, when affording the high resolution CFD meshes, the aerodynamic performance is simulated accurately by solving the Renolds-Averaged-Navier-Stokes (RANS) equations. Third, the data interface between structural deformations and aerodynamic pressures are carefully designed to transfer information for the CFD/CSD coupling simulation. Finally, the static aeroelastic analysis is performed by AeLasV2.0.4 to estimate the aeroelastic behavior of ET480 to support its aerodynamic designing and structural designing.
