This paper describes research aimed at producing a shaft-line-embedded starter/generator for an aircraft gas turbine. This machine needs to run in a very high ambient temperature of around 350°C, whilst at the same time having a very high specific output. A review is made of possible designs that highlights potential mechnical and thermal problems and which eliminates the use of some machine topologies. The paper suggests that an outer rotating segmented rotor switched reluctance motor toplogy could satisfy all the thermal, mechanical and electromagnetic requirements. An initial protoype has been constructed to allow verification of the design and the design methods used. Preliminary results indictiate that the performance, size and thermal requirements can be achieved using a fully developed version of this machine. © 2005 IEEE.
