Abstract

This work gives an overview of the nonlinear reduced order modeling (ROM) approach for unsteady aerodynamics developed by DLR, and its application to gust simulations. Here, physics-based ROMs based on high-fidelity CFD are used to predict approximate aerodynamic solutions in terms of the pressure distribution for different gust wave lengths and amplitudes. High-fidelity simulations computed with DLR's CFD solver TAU serve as training data to build the ROM with DLR's SMARTy toolbox and as a reference for the gust responses predictions. Results are presented for an airfoil and for a generic transport aircraft in transonic flow.
