Frequency Domain Approach for Transonic Unsteady Aerodynamic Modelling applied to a 3D Wing

摘要

This work introduces a method for the construction of a reduced order model in the frequency domain. With input data obtained with the TAU linearized frequency domain solver applied to a wing, the reduced order model shows a strong ability to reconstruct the full order frequency response of the lift and pitching moment. Based on a 2D method, the wing is sliced in different strips; a sensitivity analysis is carried out on each strip and on the total forces and moments to understand the influence of some parameters on the accuracy of the model.
