Chaotic Response of Aerosurfaces with Structural Nonlinearities
Abstract
An analytical and experimental research activity is being performed to investigate the chaotic response behavior of aerosurfaces containing discrete structural nonlinearities. Chaos is the paradoxical emergence of random-like motion in completely deterministic nonlinear systems. This research is developing an understanding of an aerosurface containing discrete structural nonlinearities. The dynamic behavior of a rigid aerosurface has been investigated analytically and experimentally. The rigid surface analysis and test activities are to be continued. A flexible aerosurface will be designed and fabrication begun during the second year. The third year of the program will move to test and analysis of the flexible aerosurface. Studies have been performed for a long range of rigid aerosurface configurations and various root spring stiffnesses and nonlinearities. Test apparatus has been designed and fabricated to experimentally demonstrate the nonlinear behavior of a rigid aerosurface containing discrete structural nonlinearities. Wind tunnel testing for the rigid aerosurface configuration has been initiated and evaluation of the results of the wind tunnel tests is underway. Initial design and fabrication of the rigid aerosurface dynamic test setup was completed.
