The synthetic flow field of Vectoring control of a primary flows with dilator using microjet actuators was Numerical studied by the overall flow field calculation model-X-L model. The result shows that the primary flows with dilator deflected larger than no one. And the angle of dilator has an optimal value. The reason of primary flows deflected was analyzed. There are three stage sections that the “low pressure closed reticular flow region” results in non-equilibrium of pressure along the primary jet’s orifice; the microjet roll sucked and the primary flow coupled in each other in the near catchment area; the microjet and the primary flow coupled in each other in the far catchment area.
