Contents Notes
A test program was conducted to determine the size and distribution of JP-4 fuel droplets when fuel was dispersed at a constant fuel nozzle exit velocity into a subsonic airstream. Testing was conducted at free-stream flight velocities ranging from 200 to 400 knots at altitudes ranging from 12,000 to 25,000 feet with flow rates of approximately 13, 75, and 290 1bm/min. Holograms of the fuel droplets were taken 18 feet downstream of the fuel nozzle exit plane. Representative histograms of fuel droplet size distribution and average fuel droplet diameter are presented. Average fuel droplet diameter was not significantly affected by any of the test variables. All arithmetic average fuel droplet diameter data were within a 19- to 36-micrometer band.
