| Abstract: | The previous papers have offered the distant vision of an all-electric aircraft?one which fully exploits the intrinsic features of electric power and electronic controls. This paper examines the path to that vision and the barriers along the way?some of which appear relatively easy to overcome while others are more formidable. It is interesting to conjecture what an all-electric aircraft will look like. The all-electric technologies may offer many design options and this paper suggests some tantalizing possibilities. The National Aeronautics and Space Administration (NASA) has sponsored or conducted a number of activities to foster the development of an all-electric airplane. The results of these activities are presented. Finally, in a look to the future, two NASA new initiatives are briefly discussed. |
