To describe typical ignition systems in general usage and their parameters that warrant considerations during the development of a gas turbine engine. To describe those parameters in gas turbine engine design and, in particular, burner configurations that influence the type selection and performance of the ignition system. To indicate the areas where future work may uncover important effects having a direct bearing on certain interrelated parameters, with resultant benefits to both the engine and ignition designers. To provide the designer of gas turbine engines with a working knowledge of the interrelation between engine performance objectives and the part played by ignition in meeting the objectives. To present a definitive collection of standard references, nomenclature, and descriptive terminology sufficient to provide a basis for design approach in specification of gas turbine ignition systems. To stimulate further work necessary in the development of knowledge of the unknown, interrelated parameters.
