A high power efficient Eh6G dye laser pumped by a copper vapor laser was developed with longitudinally pumped geometry and jet stream on the basis of this theory.
First, free wake analysis was carried out to calculate the rotor wake geometry and the downwash around the engine jet space.
首先应用自由尾流分析技术来计算旋翼尾迹和发动机绕排流空间的洗流速度。

Results show that the effects of incoming Mach number and the nozzle geometry are pronounced, while the jet-momentum ratio has little affects on the gains defined here.
