Abstract
An experimental investigation was conducted to determine
if there is a relationship between the cold flow characteristics
of velocity, pressure distribution, and turbulence intensity
and the reacting flow performance and combustion characteristics
of a solid fuel ramjet. The effects of configuration
cind air flow changes on the above characteristics were examined.
Average regression rates and combustion efficiencies were not
significantly affected by changes in configuration. These variations
in test conditions significantly affected the centerline
turbulence intensity but not the near-wall turbulence intensity
in cold flow. The use of bypass resulted in decreases
in regression rate and efficiencies for all cases. Attainable
performance appears to be most strongly related to near-wall
turbulence intensity/mixing and to the amount of fuel reaching
the aft mixing chamber.
