Estimation of dynamic stability coefficients for aerodynamic decelerators using CFD. Stern, E., C., Gidzak, V., M., & Candler, G., V. In 30th AIAA Applied Aerodynamics Conference 2012, pages 2217-2230, 2012. AIAA Paper 2012-3225.
Paper
Website doi abstract bibtex A method for performing dynamic simulations of entry vehicles is developed. This capability uses existing infrastructure within the US3D flow solver, developed for doing fluid structure interaction (FSI) simulations, to allow for up to six degree of freedom (6- DoF) simulations. Inviscid, free-to-oscillate simulations of the Mars Science Laboratory (MSL) capsule at Mach 2.5 and 3.5 are used to evaluate different data reduction methods. It is found that many simulations may be required to get reliable data. The computed pitch damping coefficients show comparable trends to ballistic range data, though they differ in magnitude, particularly at high angles of attack. Preliminary viscous simulation results are presented, and show improved agreement with experimental data compared to the inviscid analysis. © 2012 by the American Institute of Aeronautics and Astronautics, Inc.
