  • Numerical simulation was applied to study internal flow structure and performance of counterflow thrust vectoring nozzle with geometric configuration. Results indicate that thrust vectoring angle increased with the increasing of slot height and terminal angle when the jet was not attached to the collar, while resultant thrust ratio decreased. Suction second flow shifted from coflow to counterflow, while the mass flow rate increased. The thrust vectoring angle decreased with the increase of terminal angle; resultant thrust ratio firstly increased but then decreased. During the procedure of increasing terminal angle, suction second flow shifted from counterflow to coflow, and mass flow rate was less than 2%, but decreased and then increased.
