Unsteady Aerodynamic Forces Mixed Method for Aeroservoelasticity Studies on an F/A-18 Aircraft

Botez and Biskri discuss the two classical methods used in the aeroservoelasticity for the conversion of unsteady aerodynamic forces from the frequency into Laplace domain. These two methods are the least squares (LS) and the minimum state (MS). The method presented here gives better results in term...

Zusammenfassung:Botez and Biskri discuss the two classical methods used in the aeroservoelasticity for the conversion of unsteady aerodynamic forces from the frequency into Laplace domain. These two methods are the least squares (LS) and the minimum state (MS). The method presented here gives better results in terms of execution speeds and precision in comparison to the results obtained by the LS method for an F/A-18 aircraft.
