This report describes a method of semiconductor resistance measurement using controlled energy levels and a digital processing oscilloscope to acquire and process test data.
This report describes basic methods, typical results, limitations, and technical variables which may provide some relative performance expectations for different lots of the same material, or comparison characteristics for different materials. This testing alone does not assure satisfactory operation in the engine, i.e., there is not a direct relationship to actual engine performance.
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.
