Numerical studies have been carried out using a validated two-dimensional standard k-
omega turbulence model for the design optimization of a thrust vector control system using
shock induced self-impinging supersonic secondary double jet. Parametric analytical
studies have been carried out at different secondary injection locations to identifying the
highest unsymmetrical distribution of the main gas flow due to shock waves, which produces
a desirable side force more lucratively for vectoring. The results from the parametric studies …
