随着向多电动飞机（MEA）的转变，一个关键的研究领域是开发商业上可行的系统，这些系统可靠、高效、质量低，并且与当前和未来飞机的功率和多路复用要求兼容和相称。在旋翼机中，采用更多的电力系统来取代传统的机械和液压系统的速度被认为比固定翼飞机要低得多。然而，最近有越来越多的证据表明，四重电动尾桨（ETR）是一个技术上可行的解决方案。本文展示了支持四个独立发电机的最可靠配置的方法，这些发电机需要为四路尾桨驱动器提供动力，并考虑到每个独立通道中的功率损失、目标可靠性设置和支持可靠性分析所导致的故障严重程度。得出的结论支持特定的发电机混合串并联配置，并确定了与齿轮箱可靠性相关的进一步工作，这些工作支持该配置的可靠性实现。
With the move to more electric aircraft (MEA), a key area of investigation is the development of commercially viable systems which are reliable, efficient, low mass, and are compatible and commensurate with the power and multiplex requirements of current and future aircraft. In rotorcraft, the pace of adopting more electric systems, to replace conventional mechanical and hydraulic ones, say, is perceived as being much lower than in fixed wing aircraft. However, recently there has been growing evidence to suggest that a quadruplex electric tail rotor (ETR) is a technically viable solution. This paper shows the methodology to support the most reliable configuration of the four independent generators required to power such a quadruplex tail rotor drive, and takes account of the failure severity due to power loss in each independent channel, target reliability setting, and supporting reliability analyses. The conclusions drawn support a particular hybrid series-parallel configuration of generators, with identification of further work related to the gearbox reliabilities which support the reliability attainment for the configuration.
