通用电气 GE36 (General Electric GE36)是一种实验性飞机发动机, 由涡轮风扇发动机和涡轮螺旋桨发动机结合而成,被称为无涵道风扇发动机 (UDF)或桨扇发动机。由通用电气航空开发,[3] 同时,其CFM国际的平等合作伙伴斯奈克玛参与了 35% 的开发。[4] 由于石油输出国组织解除了石油禁运的限制,GE36 的开发于 1989 年被取消。
2021年,CFM国际再次提出了同为无涵道风扇发动机的Rise发动机计划,宣称能比当前已商用化的产品能再减少20%的燃料使用,并已经进行了100次以上的测试。[5]

With potential fuel savings of up to 45% over the best high bypass turbofans, and at speeds of Mach .8, the UDF will mean major cost reductions and greater profitability for the airlines. This engine can also be scaled to any thrust size, to serve a wide variety of aircraft.
