Abstract:

We report video-rate imaging polarimetry observations of boosting rocket exhaust plumes obtained with the Lockheed Martin ATC Simultaneous Stokes Imaging Polarimeter (SSIP). The unique design of the SSIP, mounted to a tracking telescope, allowed us to acquire rocket plume imaging polarimetry over a period of minutes for each of three launches, observing the plume phenomenology at a variety of altitudes and aspect angles. Our data includes image polarimetry of solid and liquid rocket exhaust plumes and mixing of the two exhaust flow fields. We also present multi-spectral image data, showing for the first time distinct shock structures in the plumes at two wavelengths.
