Design, construction, and testing of an aero‐engine starter‐generator for the more‐electric aircraft

Abstract

This study describes the design, construction, and testing of an aero‐engine starter‐generator and its associated power electronic converter. A high‐speed, permanent magnet machine and a dual‐channel machine‐facing converter with an electrical power offtake rating of 95 kW have been developed for a small civil turbofan application. The study also describes the more‐electric architecture into which the machine and converter are integrated and reviews the multi‐faceted performance specification, which is a common feature of machines of this type.
