Demonstration of a flight capable system for plume spectroscopyA small, rugged, high-speed/resolution Fabry-Perot interferometer (FPI) based spectrometer has been developed for detecting the spectral signatures of eroding rocket engine components during ground tests and/or flight operations, with a view to use in future rocket engine health-management systems (HMSs). A flight-capable HMS will furnish prognoses and responses to incipient engine failures, as well as diagnoses of wear and degradation during maintenance. Attention is given to the development of a prototype FPI spectrometer for demonstration and validation testing at NASA-Marshall.
