High Altitude Rocket Plume Structure: Experiment and Calculations

Abstract

Values of impact pressure and species number density measured in a wind tunnel experiment simulating a high-altitude rocket exhaust plume are compared with values calculated with a computer code. Considering a number of uncertainties in the absolute calibrations of the experiment, agreement is generally considered satisfactory for conditions in the mixing region between plume and free stream gases. However, in the forward part of the plume, the data suggests that free-stream gas penetrates further into the plume than the calculation predicts; the cause of this discrepancy is unknown.
