The goal of the present work was to upgrade the data
acquisition system (DAS) in the high-speed building of the
Turbopropulsion Laboratory (TPL) and to develop a high-speed
acquisition capability for pressure measurements for both the
TPL and the new Gas Dynamics Laboratory (GDL) . Based on the
use of the Hewlett Packard HP9000 Series 300 Computer as the
system controller, a 96-channel high-speed pressure DAS was
developed using Scanivalve ZOC-14 modules and a CALSYS2 000
calibrator. The system allowed acquisition times for current
wind-tunnel experiments to be revised from four minutes to
eleven seconds. Also, new software was written to acquire
data from existing rotary pneumatic Scanivalves and HP-IB
compatible instrumentation so that all other existing
acquisition capabilities were maintained in both laboratories.
