Abstract EN
Several new systematic methods for high fidelity and reliability calculation of static and single dynamic derivatives are proposed in this paper.
Angle of attack step response is used to obtain static derivative directly; then translation acceleration dynamic derivative and rotary dynamic derivative can be calculated by employing the step response motion of rate of the angle of attack and unsteady motion of pitching angular velocity step response, respectively.
Longitudinal stability derivative calculations of SACCON UCAV are taken as test cases for validation.
Numerical results of all cases achieve good agreement with reference values or experiments data from wind tunnel, which indicate that the proposed methods can be considered as new tools in the process of design and production of advanced aircrafts for their high efficiency and precision.
