A DESCRIPTION OF THE CONTROL AND READOUT SYSTEM FOR A FORCEDOSCILLATION BALANCE

Abstract

A control and data acquisition system was built and used in forced-oscillation tests of aerodynamic models in the 16-Foot Transonic and 16Foot Supersonic Tunnels of the Propulsion Wind Tunnel Facility, AEDC. The drive is electrohydraulic and is controlled by a position feedback loop. The data acquisition system provides the information required for the on-line determination by a digital computer of the degree of model dynamic stability or instability in pitch. The design, analysis, theory of operation, and general fabrication of the system are covered. (Author)
