Abstract

Numerical predictions by coupling the aerodynamic code DLR TAU with trajectory optimization program REENT-6D for different atmospheric models are presented in this paper. Using balloon data and existing models, an atmospheric model has been developed and showed better agreement between numerical and experimental results than conventional atmospheric models. Firstly, roll rates are compared with experimental flight data. Secondly, the estimated error of the positioning system HNS is taken into account for starting conditions. Lastly, measured pressure data are compared to numeric. Assuming the fins of the first stage are skewed, the agreements of numerical coupled calculations with flight measurements are adequate.
