| Abstract: | The aerodynamic properties of thrust-vectoring et vane were studied with motor test and numerical simulation. Based on the wind tunnel and jet experiments, the six-force model of motor was set up and the two experiments on motor ignition were carried out. Taking the 3-.D viscous turbulence and the similar geometry to true motor as models, the numerical simulation was processed. The results show that the experimental method and model are suitable, and the numerical simulation is consist with the experiments. |
