A fluid thrust vectoring nozzle model was established, and the numerical simulation was used to study the model and flow. When the control slot was closed at the same time, the control slot did not work and the main direction was in the central region. When the control slot opens at the same time, due to the influence of the mainstream low pressure, the outer air flow flows into the mainstream from the upper and lower air inlets respectively, and the mainstream flow increases slightly. The main flow will not deflect when the upper and lower air inlets are opened or closed at the same time, thus verifying the accuracy of the calculation model. When one side of the air inlet is opened and the other side of the air inlet is closed at the same time, the external gas flows into the mainstream from the open side of the air inlet and impacts the mainstream. As the mainstream is impacted asymmetrically, it deflects to the closed side of the entrance. Fluid thrust vectoring nozzle has the advantages of simple structure and high control efficiency.
