Efficient Numerical Aeroelastic Analysis of a High-Aspect-Ratio Wing Considering Geometric Nonlinearity

The aerodynamic models used panel methods or Euler/Navier - Stokes equations for the aeroelastic analyses. However, it is difficult to consider the effect of a camber and a thickness of a wing when using these methods with linear aerodynamic models. On the other hand, Euler/Navier - Stokes equations...

Description
Summary:The aerodynamic models used panel methods or Euler/Navier - Stokes equations for the aeroelastic analyses. However, it is difficult to consider the effect of a camber and a thickness of a wing when using these methods with linear aerodynamic models. On the other hand, Euler/Navier - Stokes equations are inefficient for three-dimensional configurations due to the high computational cost associated with these equations. Thus, an efficient aeroelastic method is presented to include both geometrical structural and aerodynamic nonlinearities in this research. The transonic small- disturbance theory (TSD) is well known as an efficient method for aeroelastic analysis.
