Abstract:

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 highspeed acquisition capability for pressure measurements for both 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 CALSYS2000 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.
