Data Acquisition and Processing Software for the Low Speed Wind Tunnel Tests of the Jindivik Auxiliary Air Intake

Abstract

Data acquisition software has been developed for the wind tunnel tests of the auxiliary air intake of the Jindivik pilotless target aircraft in the AMRL Low Speed Wind Tunnel (LSWT) using the new Pressure Systems Incorporated (PSI) 8400 Measurement System under the control of an IBM PS/2 computer. The recent upgrade of the data acquisition system for the LSWT and the replacement of the mechanical Scanivalve pressure measuring system with PSI electronic pressure scanners has required major modifications to be made to existing software. To minimise the changes needed and to provide compatibility with data processing for previous tests the data acquired by the PSI electronic pressure equipment are transferred to the dedicated LSWT DEC PDP-11/44 mini- computer for storage and processing. This report describes the development and operation of new software for the LSWT tests of the Jindivik auxiliary air intake.
