An advanced linear motor system for electromagnetic launch: development and opportunities

The requirement for launching aircraft, in the future, from electric powered aircraft carriers has led to an interest in electro-magnetic launch systems to replace the steam catapult. This paper will discuss the successful development of an advanced linear motor launching system. The electro magnetic catapult system (EMCAT) will be explained along with descriptions of the major components. The results of some of the hardware testing will be revealed and the implications of these results on a full system will be discussed. In addition the advantages over a steam catapult, system maturity, impact upon ship design and potential future application for the technology are also discussed.
