Conceptual Study of the LB/TS (Large Blast/Thermal Simulator) Instrumentation, Data Acquisition and Facility Controls System.
Abstract
A conceptual study of a comprehensive instrumentation, data acquisition and control system supporting the Large Blast/Thermal Simulation Facility (LB/TS) addressing physical sensors; optical sensors, data acquisition, reduction, and display; facility controls; calibration systems; software, interface hardware; and associated equipment is described. Physical sensors for measurement of pressure, temperature, heat flux, strain, displacement, and acceleration are discussed. Over ten candidate optical/non-intrusive measurement systems are evaluated for temperature, displacement, flow velocity, and other measurements. Three basic data acquisition systems--a conventional digital system, an analog tape system and a hybrid analog/digital system--are evaluated to acquire process data from over 100 blast wave, flow field, thermal radiation simulator (TRS), and target response sensors. A system for monitoring of the facility status and control of the facility operation is also described. The complete sensor, data acquisition, and control system as developed in this study will provide for robust, durable operation in the high-enthalpy, impulse environment of the LB/TS. Keywords: Impulse facilities; Blast waves; Instrumentation; Data acquisition systems; Physical/intrusive sensors; Thermal radiation simulators.
