Computer Control Interface to Operate Turntables in the Test Section of a Wind Tunnel

摘要

The Low Speed Wind Tunnel at the Aeronautical and Maritime Research Laboratory (AMRL) has, as part of its system, two interchangeable chambers, known as test sections where models to be tested are mounted. One of the requirements of a recent upgrade to the Low Speed Wind Tunnel control and data acquisition system was the ability to precisely position the turntables using computer control. This report describes the electronic hardware and software developed to enable computer control of the turntables by wind tunnel personnel.
