Static Nonlinear Aeroelastic Analysis of a Blended Wing Body

*† ‡ § ** †† A high -fidelity computational process is applied to assess the contributions of aerodynamic nonlin earities to the airloads sustained by a blended -wing configuration with different static aeroelastic deflections . The effects of nonlinearities are inferred through comparison of the computational results with those predicted by a widely accepted linear aeroelastic procedure. Structural deflections prescribed in the nonlinear analysis are those obtained from the linear methodology, a step taken in prelude to developing a production quality, high -fidelity aeroelastic methodology that has the added benefit of ensuring the consistency of the geometrical changes. Of specific interest is the ability of the current process to re -generate rapidly grids for aerodynamic analysis in response to structural deflections.
