Soot Particles Size and Concentration Determination from a Kerosene/ Gaseous Oxygen Rocket Plume

This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A799853. The abstract provided by the Pentagon follows: An experimental investigation was conducted to measure soot properties and concentration, and infrared signature of the plume of a kerosene/ gaseous oxygen rocket motor. Multiple-wavelength measurements were used to obtain soot parameters. It was found that the multiple-wavelength technique appeared to work well for obtaining soot properties and concentration. The results implied that the soot particulate was very porous for the most fuel-rich conditions and became more compact as the 0/F ratio increased.
