摘要

For the dual-slot jet controlled two-dimensional shock vector nozzle, the effect of flow distribution on the vector performance of the nozzle is studied by RANS method, in which the total flow rate is unchanged. The results show that the flow distribution has no effect on the thrust coefficient. Increasing the downstream jet flow and reducing the upstream jet flow helps to improve the vector angle and vector efficiency, and the effect is obvious when there is separation and re-attachment between the two jets. Increasing the upstream jet flow and reducing the downstream jet flow will reduce the vector angle. The effect is not noticeable when the separation zone between the two jets is stable and no re-attachment. Maintaining a stable separation zone between dual-slot jet without re-attachment helps improve the vector performance of SVC nozzles. The dual-slot jet flow distribution should aim to eliminate reattachment of separation between jets.
