Some Factors Controlling the Development of Electrical Ignition of Aero Engines

Published online by Cambridge University Press:  28 July 2016

Extract

The conditions in which the various parts of the ignition system of aero engines have to operate have during recent times become much more onerous than hitherto. Many of the developments which have occurred in modern engines have caused the emergence of new problems so far as the ignition system is concerned, and have made older problems which had been only partially solved, even more difficult. This paper presents a review of some of the more important factors which are involved, an account of how the problems which have arisen have been solved, and indications given of limitations which still exist in various directions.
