| Sumario: | A 3D combustion simulation research about the varied inlets crossing positions of the solid ducted rocket with two inlets is carried out to study the influence of inlets crossing position on the performance of solid ducted rocket with fixed primary fuel injection. The performance of solid ducted rocket changes greatly when the crossing position moves from the side far away from the inlet to the side near the inlet. And the temperature field distortion at the outlet of the combustor declines at first, then it rises, but it decreases in the end. When crossing position is at the center of the combustor, the nonuniformity of the combustor outlet reaches the maximum. While the performance of solid ducted rocket opposites with the temperature field distortion, that means, the lower the distortion, the higher the engine performance. When the temperature field at the combustor outlet is uniformity, the less nozzle lost would be gotten as well. |
