Prediction of aerodynamic derivatives using Computational Fluid Dynamics (CFD)at transonic speed. Journal of Transport System Engineering, 4 (1). pp. 8-16. ISSN 2289–9790 (2017)
Abstract
This paper aims to evaluate the aerodynamic derivatives from computational fluid dynamics to obtain derivatives at transonic speed. The derivatives are computed using the equation of Reynolds-Averaged-Navier-Stokes and a time-domain flow solver. In order to predict this study, standard dynamic model geometry is adopted. Three separated methods are used to calculate the aerodynamic derivatives. Then, the comparison between low-fidelity solver, high-fidelity computational and experimental data available showed that a satisfactory agreement was observed simultaneously. The study conducted showed the evaluation of unstable aerodynamic derivatives prediction, useful for longitudinal motion. The derivatives such as normal force derivatives and pitching moment derivatives function as important derivative sin the aerodynamic coefficient for the dynamic motion analysis.
