摘　　要：通过分析航空发动机和燃烧驱动CO2气动激光器的相似性,探讨了将航空发动机改装成CO2气动激光器的可行性.提出了涡轮喷气CO2气动激光器的概念和基本框架,分析了其中涉及的各项关键技术和初步解决方案.针对典型航空发动机的工作状态,设计了阵列喷管型面,并对小信号增益和喷管内流场分布进行了数值计算.结果表明,利用航空发动机燃气可以获得较高的小信号增益,涡轮喷气CO2气动激光器存在其合理性和可行性.The combustion driven CO2 gasdynamic laser（GDL） is similar with advanced aero-engine.The possibility of refitting a CO2 GDL from an aero-engine was discussed here,then the conception,basic frame and key techniques were analyzed.A nozzle figure was designed in allusion to the typical working condition of aero-engine,small signal gain and flow field distribution were calculated primarily.The result that high small signal gain is achieved shows that CO2 GDL based on the turbojet is possible.
