Not Available The proposed Phase I program targets the development of an integrated measurement system for characterizing advanced propuslion systems. Key to this system will be the use of computational modeling inconjunction with the development of advanced instrumentation. The modeling program will consist of two portions. First, a combustor kinetics code willbe implemented to predict combustor performance and emissions with higher hydrocarbon fuels, with calculations being applied both to the combustion tube of a pulse detonation engne and to a high-equivalence-ratio gas-turbine combustorwithconventional jet fueland air. Secod, a multi-dimensional computational code will be implemented to study important spatial and temporal behavior of relevance to instrumentation designand application. Advanced instrumentation willalso be demonstrated after choosing the most relevant techniques. A demonstration measurement of pressure and temperature is planned usng the dual-pump CARS technique. In addition, filtered Rayleigh scattering and laser-induced fluorescence will be applied. In each case, the test will be performed on a laboratory researc combustor. A fiber-optic-based probe willalso bedesigned for concentration measurements in cases where optical access is limited.
