Model Bourne Data Management System for Wind Tunnel Testing
Abstract
This report covers the preliminary design of a modern wind tunnel data processing system capable of producing immediate test results in engineering units by employing an on board model mounted data multiplexing and signal processing unit communicating through a minimum of through sting wiring to its own personal computer based data acquisition and processing system. Up to 1000 channels of data can be acquired at speeds up to 83K samples per second. Since the system is modular it can be fitted to a wind range of models with a minimum of hardware modification. Also, since gains and sampling rate & sequence are computer controlled, needed adjustments to data processing can be made from a keyboard, without hardware changes, even while a test is in progress. The work accomplished in this project included all circuit design, component selection, circuit board design and breadboarding and verification of the overall design operability. At this point, the design has proceeded to the point where it is ready to be prototyped during a Phase II effort. During the proposed follow on work, the system prototype will be tested to verify its performance during bench and wind tunnel testing following installation in a suitable model. At the completion of this work, the system will be ready for commercial application.
