ONLINE ANALYSIS CAPABILITIES DEVELOPED TO SUPPORT THE ACTIVE FLEXIBLEWING WIND-TUNNEL TESTS

A variety of on-line analysis tools were developed to support two acti ve flexible wing (AFW) wind-tunnel tests. These tools were developed t o verify control law execution, to satisfy analysis requirements of th e control law designers, to provide measures of system stability in a real-time environment, and to provide project managers with a quantita tive measure of controller performance. Descriptions and purposes of c apabilities that were developed are presented in this article along wi th examples. Procedures for saving and transferring data for near real -time analysis. and descriptions of the corresponding data interface p rograms are also presented. Although much of the on-line analysis capa bilities described herein are not technically new, the implementation for near real-time analysis to verify and evaluate controller performa nce is new, and is included in this special Journal if Aircraft issue for completeness in describing the AFW mind-tunnel testing. The on-lin e analysis tools worked well before, during, and after the wind-tunnel tests, and proved to be a vital and important part of the entire test effort.
