在燃气涡轮发动机,特别是齿轮传动式涡扇发动机上的领导与创新“使您当选了美国国家工程学院院士,请您谈一谈令世人瞩目的普惠公司齿轮传动式涡扇发动机哪些创新改变了游戏规则呢?保罗·亚当斯:齿轮涡扇TM发动机采用普惠公司研发的齿轮系统,能使发动机风扇在不同于低压压缩机和涡轮机的速度下运转,因此发动机涵道比可以增加到超出传统配置可以实现的水平,而且在减小燃油消耗和降低噪音方面产生了阶段性变
Leadership and Innovation on Gas Turbine Engines, and Geared Turbofan Engines in particular, ”Brought You to the National Academy of Engineering, United States, to Talk about What’s New in a Pratt & Whitney Geared Turbofan Engine Changed the rules of the game? Paul Adams: Gear Turbofan TM engine Pratt & Whitney developed a gear system that allows the engine fan at a different speed than low-pressure compressors and turbines, so the engine bypass ratio can be increased beyond The level at which traditional configurations can be achieved, and the phased change in fuel consumption and noise reduction
