| Abstract: | An annular throat plug nozzle is studied by the calculation method of flow-field numerical simulation.The flow-field structures and the characters of the plug nozzle under the condition of different freestreams are compared and calculated.The structure design of the plug nozzle is unique. The analysis shows that the plug nozzle has stable performance at high altitude and high speed,and has more excellent low altitude performance in comparison with the bell nozzle. |
