摘要
通过流场数值仿真计算方法对环喉型塞式喷管进行了研究,对比计算了不同外流条件下塞式喷管的流场结构和性能。分析表明该塞式喷管的结构方案独特,具有稳定的高空高速性能,与传统的钟型喷管相比低空性能更优异。
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.
