Abstract:

This lecture series covers the recent advances of planar optical measurement techniques with respect to their applicability to gas turbine component tests. During the last years much progress has been achieved in various known techniques, and new methods have been developed from which a significant increase of the experimental output of propulsion tests and therefore remarkable cost reduction can be expected. To bring this status into the knowledge of the propulsion specialists is the aim of this lecture series. Its theme is focused on laser measurement methods for the analysis of the internal flow and reaction processes in propulsion engines. It will address techniques for the measurement of flow velocity, flow density, pressure, temperature and species concentration. Only those methods are introduced which are far enough developed to be applicable to the rough test conditions of propulsion experiments. The course will inform the audience about the fundamentals of the advanced measurement techniques, as well as demonstrate their use in the context of practical applications. The material in this publication was collected from the research centers of the different NATO nations. It will transfer to the propulsion engineers in a condensed manner the information of the newest capabilities of modern test techniques thus providing the knowledge base for tomorrows measurement instrumentation of propulsion test facilities. NATOs specific interest in sponsoring this event is based on the requirement for engines of extreme performance characteristics which cannot be realized without further improvements of both CFD and measurement technologies.
