SNOB/GREG CALIBRATOR DEVELOPMENT

THE OBJECTIVES OF THIS WORK ARE TO ESTABLISH THE DESIGN REQUIREMENTS, TECHNICAL FEASIBILITY A BASIC DESIGN, AND A COST DATA BASE FOR DESIGNING AND CONSTRUCTING A LOW COST BUT ADEQUATE CAPABILITY FOR CALIBRATING PRESSURE INSTRUMENTATION USED FOR MEASURING DUSTY BLAST FLOW. IN PARTICULAR SUCH A CALIBRATION FACILITY WOULD BE CAPABLE OF CALIBRATING SINGLE AND MULTIPLE SNOB/GREG PROBES AT THE FLOW SPEEDS AND DUST DENSITIES OF INTEREST TO DUSTY FLOW EXPERIMENTS CONDUCTED IN LARGE AND SMALL HE FIELD TESTS AND IN SHOCK TUBE TESTS. THE CALIBRATOR IS SORELY NEEDED FOR ESTABLISHING THE ACCURACY OF DUST FLOW INSTRUMENTATION FOR THE MISTY PICTURE EVENT AND SIMILAR SUCH TESTS. AT THIS POINT NO POTENTIAL COMMERCIAL APPLICATIONS HAVE BEEN IDENTIFIED FOR THE CALIBRATOR.
