Abstract:

Optical measurements have been made to determine the radiant energy emitted by diffusion flames from the following aircraft combustible fluids JP- 4, JP-5, JP-8, AVGAS, MIL-H5606B and MLO-68-5. Data was taken under sea level conditions and simulated altitude conditions up to 35,000 ft. The spectral range of data taken is from 200nm to 15um. Results indicate the majority of emitted energy is in the visible and near infrared. The major differences in the spectra taken at 35,000 ft. versus the spectra taken at sea level is the decrease in IR and visible energy, with an anticipated increase in UV radiation.
