This Aerospace Standard establishes the diameter - pitch combinations of ISO metric 60 screw threads recommended for use in the aerospace industry for metric module shaft of bearing retaining screw threads.
To describe typical ignition systems in general usage and their parameters that warrant consideration 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.
