Abstract:

This report covers the development of a modern model mounted wind tunnel data acquisition and processing system called MDARS, short for Modular Data Acquisition and Recording System. During this Phase, prototypes of the model borne components and the pc interface were developed. The system was then installed in a HP-MaRV model for demonstration testing in AEDCs wind tunnel B. Following these tests the performance and durability of the system was analyzed and lessons learned were identified and incorporated into a production version of the system. These activities resulted in a proven data system, ready for marketing. The MDARS uses modern high density surface mount components in a compact modular bus arrangement which allows a size which can be accommodated by most wind tunnel models. It also allows the system to be controlled and data to be acquired by a modern personal computer thus decreasing or eliminating dependence on facility data systems. The system multiplexes all data channels and converts all analog signals digital. The remote system communicates with the Control Personal Computer by fiber optic cable. The use of MDARS will reduce facility data system dependence while reducing test set up costs and schedule delays. Wind tunnel testing, Data acquisition systems.
