Abstract :

Air-jets, laterally injected into a high-speed flow through axisymmetric convergent�divergent nozzle are investigated to present the effects of the air thrust vectoring within the framework of an innovative propulsive system. The very complex 3D flow field parameters distribution and character aerodynamic features were studied. For the purposes of the numerical analysis, fluent code with additionally implemented user-defined file is applied. Different nozzle geometries, models with injected high-speed lateral streams are numerically simulated to determine how parameters and flow conditions affect the thrust vectoring. Valuable experimental data were compared with the results obtained from the numerical simulations. The laterally injected air-jets are an innovative concept for thrust vectoring that could has various applications in practice.
