A scaled experimental investigation has been conducted to determine the wall static pressure distributions of a shock induced axisymmetric fluidic vectoring nozzle with a slot in its divergent section when the nozzle pressure ratio(NPR) was 3～10 and the flow flux ratio of the secondary flow injection to the primary flow(Ws/Wp) was 0%～20%.The results indicate that the internal flow characteristics are complex 3-Dimensional

for the secondary flow injection resulting in discrepancy of the circumference wall static pressure.NPR and Ws/Wp influence greatly the wall static distributions and under certain conditions they would influence the flow of the convergent section of the nozzle.When NPR=4

Ws/Wp≥15%

the shock waves may hit the lower flap which is farthest to the secondary flow injection in circumference direction

separating flows and bringing on higher wall static pressure.
