本文介绍了一种低排放、50kw汽轮发电机的研制。它给出了一个详细的描述，有利于混合动力电动汽车在不同的驾驶周期驱动的关键设计特点。虽然涡轮发电机是为混合动力汽车设计的，但其他应用，如备用和一次发电，将受益于它的特性。这些特点包括极低的废气排放、低成本、高可靠性、高燃油效率、紧凑的设计和低噪音水平。汽轮发电机是相对独特的，因为涡轮，压气机叶轮和发电机都安装在一个单一的，共同的轴是由空气轴承支撑。这些特点消除了变速箱和油润滑的需要，通常发现在传统的汽车和燃气涡轮发动机。根据美国能源部混合动力汽车推进计划，联合信号公司为福特汽车公司开发了50千瓦涡轮发电机。涡轮发电机被设计成适合于汞貂的发动机舱。联合信号公司最初在美国陆军的APU开发项目中证明了这一创新概念。为该计划开发的单元已经在实验室和陆军车辆测试中积累了600多个小时的操作。ASME版权所有©1998
This paper describes the development of a low-emission, 50-kW turbine-driven generator called a turbogenerator. It gives a detailed description of the key design features that benefit hybrid electric vehicles driven in various driving cycles. Although the turbogenerator is designed for hybrid electric vehicles, other applications such as standby and primary electric power generation will benefit from its characteristics. These include very-low-exhaust emissions, low cost, high reliability, high fuel efficiency, compact design, and low noise levels. The turbogenerator is relatively unique in that the turbine wheel, compressor impeller, and electrical generator are all mounted on a single, common shaft which is supported on air bearings. These features eliminate the need for both the gearbox and oil lubrication commonly found on conventional automotive and gas turbine engines. AlliedSignal developed the 50-kW turbogenerator for Ford Motor Company under the DOE Hybrid Electric Vehicle Propulsion Program. The turbogenerator is designed to fit into the engine compartment of a Mercury Sable. AlliedSignal originally proved this innovative concept in an APU development program for the U.S. Army. The unit developed for that program has accumulated over 600 hours of operation in laboratory and Army vehicle tests.Copyright © 1998 by ASME
