Automatic Data Retrieval from Rocket Motor Holograms.

Abstract

This thesis describes a technique of obtaining particle size information from holograms of combustion products. These data are needed to improve predictive capabilities of propellant performance, to provide input related to ammonium perchlorate (AP) - aluminum interactions for steady-state combustion models and to provide in motor particle size distributions to allow more accurate predictions of damping in stability analysis and two phase flow and exhaust plume signature. This study describes the use of Itex/PC software for the filtering and processing of the hologram images to reduce speckle and also, improves a Fortran program which had been written before to extract the particle feature size data from the modified image. The final step shows the statistical particle feature data exhibition by using the STATGRAPHICS (Statistical Graphics System) software. Keywords: Hologram, Image analysis, Speckle, Image action, STATGRAPHICS, Aluminum, Combustion chambers, Solid rocket propellants, Theses, Speckle interferometry. (jes)
