Abstract
The purpose of this study is to update the existing P-2V Wing Torsion/ Bending Structural Test to include computer-aided data acquisition and analysis. The system includes 20 displacement transducers, associated wiring and support framework, a dual DC voltage power supply, two Labmaster data acquisition expansion boards, an AT-compatible computer with 80286 processor and 80287 math co-processor, and ASYST software to perform all data processing. This study produced a computer package capable of significantly enhancing the utility of the basic wing torsion/bending experiment through real-time data acquisition and analysis. Manual data acquisition required approximately ten minutes per static load, with additional time for data plotting and analysis. Computerized measurements are conducted in several seconds, and the data is automatically plotted on a dot-matrix printer. This improved system allows for expansion of the experiment to include testing a larger variety of static loading problems and the basic instrumentation to explore the wing's response to dynamic loading.
