Computational Mechanics Approach for Multidisciplinary Nonlinear Sensitivity Analysis
Abstract
Efficient and accurate prediction of nonlinear airloads is necessary for designing the aircraft in the transonic regime. The flow in the transonic regime is a mixture of subsonic and supersonic flow with embedded shocks. The governing transonic aerodynamic equations are highly nonlinear and are computationally expensive to solve. The aerodynamic nonlinearities have a significant impact on the aeroelastic quantities and on the resulting designs. Hence they have to be taken into account. Full fledged euler or Navier-Stokes solution methods cannot be used in the preliminary design due to the enormous cost involved.
