A new data acquisition, display and control system for the ARA transonic wind tunnel

A new data acquisition system has been designed and manufactured by the Systems Department of the Aircraft Research Association (ARA) Ltd. for use in their transonic wind tunnel at Bedford, England. This system is based on a Radstone single-board computer utilizing a Motorola 68020 processor operating on a VME bus. The calibration system, which is referable back to national standards, supplemented by a precision bridge circuit, constantly assures the user of the quality of data being recorded. The authors highlight the development of data logging at ARA and consider the system requirements and specifications. The most important constituent parts of the system are described, as are several planned enhancements.<
