CFM的RISE计划提出的新引擎跟传统的涡桨引擎有什么区别？图中展示的是advancing open fan，其更通俗的称呼是桨扇，与安-70上的设计颇为相似，也可理解为先进开式转子。从本质上讲，对转桨扇与对转涡桨之间的差异，类似于传统涡扇与涡桨之间的区别。桨扇的叶片设计更接近于传统风扇，其主要工作环境在跨音速区域...
图中展示的是advancing open fan,其更通俗的称呼是桨扇,与安-70上的设计颇为相似,也可理解为先进开式转子。从本质上讲,对转桨扇与对转涡桨之间的差异,类似于传统涡扇与涡桨之间的区别。桨扇的叶片设计更接近于传统风扇,其主要工作环境在跨音速区域,叶片数量通常在10至18片之间,且对转的两级叶片数量并不相同。
propulsive efficiency of the engine. The advanced open fan architecture to be demonstrated as part of the RISE program will fly at the same speed as current single-aisle aircraft (up to Mach 0.8, or 80 percent the speed of sound) with a noise signature that will meet anticipated future ...
渲染:CFM 国际正在通过其 RISE 计划推进先锋技术,包括 Open Fan 等先进架构。 “我们正处于项目在真实硬件上进行真实测试并取得实际进展的阶段。” 通用电气航空航天公司副总裁兼工程总经理穆罕默德·阿里 (Mohamed Ali) 在最近于纽约举行的通用电气投资者日上谈到了 CFM 可持续发动机革命性创新 (RISE) 计划。他的话...

CFM announced theRISEproject in June 2021, with plans to enter service in the mid 2030s.[6][7] 【参考译文】CFM 在 2021 年 6 月宣布了 RISE 项目,计划于 2030 年代中期投入服务。[6][7] 6. CFM的未来 | The future of CFM In the early 2000s, CFM launched a new cutting-edge technology...
We are excited about this new engine, but we also think we need to remain flexible. If fuel prices continue to rise, we will need to raise the bar even higher and introduce even more advanced technology. For the next three years, we are pursuing parallel paths: the LEAP-X advanced turbo...
