Structural Tests of Aerodynamic Surfaces: A Systems Approach to Analysis and Design
One of the primary tasks in structural ground testing of aerodynamic surfaces is to resolve complex, curvilinear pressure fields into applied test loads. A systems approach is presented which optimally performs this analysis and integrates it with major subsequent phases of the engineering operation: specifically, correlation of actual/theoretical shear and moment curves, selection of loading pad geometry, test fixture analysis, and graphical display of the results. Computer programs are available to calculate these results rapidly using curve fitting and statistical methods modified for test data evaluation.
