Holography in Dust Erosion Facilities

Abstract

Extensive application of holographic techniques has been made in the ground test facilities at the Arnold Engineering Development Center (AEDC) for particle-field analysis and flow diagnostics. The instrumentation requirements of dust erosion facilities include a dynamic evaluation of the dust cloud, including size, number density, velocity, and distribution of dust particles. Holography has provided a unique method of performing such an evaluation. The system developed at AEDC and currently in routine use is discussed in detail. Design criteria and system capability are analyzed. It is shown that the holography system provides data which cannot be obtained with other existing instrumentation.
