摘要
自由旋涡气动窗口利用非对称喷管产生的超声速自由旋涡射流来密封高能激光器低压的激光腔,通过射流的动量改变来平衡环境与激光腔之间的压力差。提出了一种超声速自由旋涡气动窗口的设计原理和方法,讨论了其设计过程,对该种结构的自由旋涡气动窗口进行了设计和实验测试。测试表明,超声速自由旋涡气动窗口能够按设计参数运行,满足激光腔密封的要求,而且具有良好的光学质量。
Supersonic freevortex aerodynamic window (ADW) is employed to seal lowpressure lasercavity. In this article the procedures are described for determining freevortex aerodynamic window. Freevortex nozzle is designed and the performance is measured. The experiments show that the freevortex aerodynamic window can operate on design parameter and has a good optical quality.
