In order to study the thermal protection characteristics of the cooling circuit of the aero-vector nozzle actuator under dynamic conditions, the reciprocating motion process of the actuator was numerically simulated by using the Fluent dynamic grid technology, and a high temperature test bench was built to verify the correctness of the simulation model. The thermal protection effect of the actuator cooling circuit under the static and reciprocating conditions of the piston rod was compared and analyzed, and the distribution law of the flow field, pressure, flow rate and temperature of the actuator under dynamic condition was obtained. The results showed that the inlet and outlet flow rate increased greatly when the piston rod moved, so the thermal protection effect of the cooling circuit under dynamic condition was significantly better than that under static condition. The stator and sleeve sealing temperatures under dynamic condition were reduced by 29.2 ℃ and 8.0 ℃, respectively, and the cylinder temperature was reduced by 35 ℃ compared with the static condition. This indicated that dynamic calculation can predict the thermal protection performance of the actuator in real working condition more accurately. The research could provide a powerful analysis tool and design reference for improving the structure of vector nozzle actuator.
