Abstract
A theory has been derived to describe the unsteady response of arbitrary twodimensional bodies in the frequency domain. The theory provides the values of the admittance for side force and yawing moment under sinusoidal gust conditions. This approach provides indirectly the power spectra density (PSD), which is often used to characterize systems in unsteady periodic conditions (Filippone and Siquier, 2003, Filippone, 2003). The flow model is inviscid, with the assumption of small perturbations. Results are shown for a squared, a triangular, and a circular plate, as well as some road vehicles. The existence of critical damping is discussed for some cases.
