Abstract. This paper describes the impact of the More Electric Aircraft (MEA) on the environment and the main advantages the electrified aircrafts
can offer. Because of high demand of the MEA on the electrical energy, a new generator need to be designed. The authors propose a novel
homopolar starter-generator which could replace both the starter and the generator and could offer higher efficiency and reliability. The principle of
work of the new machine has explained and the new machine design has been presented.
