Paper Abstract

Substantial progress has been made toward the development and application of fast instrumentation for multispectral plume radiation measurements in high altitude simulation facilities. Fast instrumentation permits short duration testing which in turn reduces the heat load and minimizes the chamber recovery time without the addition of costly pumps. Required measurements include the spatial and spectral distribution of plume radiation from the vacuum UV through the IR. Although several instruments are still in the development stage, at this time we are reporting on the successful application of four instruments: an electronographic camera was used to obtain vacuum UV plume images for the first time; mid UV spectral emission data were obtained with a 1/8-meter Ebert-Fastie spectrometer; a thermal imaging camera provided IR spatial images of the plume in four different spectral bands: and a rapid scan Michelson interferometer acquired IR emission spectra. All these measurements were accomplished within a 1-2 sec engine firing time.
