| 摘 要： | 对于高能激光器来说 ,晶体材料输出窗口因吸收致热而无法正常工作。自由旋涡气动窗口利用超音速自由旋涡来密封低压的激光腔。本文提出了确定气动窗口所需自由旋涡气动特性的过程 ,讨论了特征线方法在非对称超音速喷管设计中的应用 ,该喷管被用来产生自由旋涡流动。

| Abstract: | The crystal window of high power laser can not work in gear because of the heat caused by absorption of high power beam . The supersonic free vortex segment is usually employed to seal low pressure laser cavity. In this article the procedures are described for determining free vortex segment properties. Characteristics method is used to design nozzle which produces free vortex segment. |
