Parametric grid fin design study for the T3 vehicle within SALTO

Kurzfassung

Numerical simulations were conducted to investigate the aerodynamic performance of grid fins for a reusable first stage, within the SALTO project. The influence of the descent trajectory was taken into account. This study provides a systematic overview of the geometric parameters of grid fins and their effects on mass and steering forces generated. The results are compared to a baseline geometry. Parameter combinations were analysed that lead to a slightly lighter and aerodynamically improved geometry.
