In this thesis, a modified iterative methodology is proposed, which improves upon existing work in literature by including geometrically nonlinear large rotation effects along the wingspan as an additional downwash into the methodology to improve the fidelity of the calculated loads. It is found that when the airframe is highly flexible, significant increases in the critical wing root loads are observed, as well as substantial changes in the trimmed aircraft configurations.A sensitivity analysis is performed on aircraft wing loads due to geometric nonlinearity, with respect to a number of conceptual design parameters. The parameters found to be most significantly affected by geometrically nonlinear effects in dynamic aeroelasticity are the out of plane stiffness of the aircraft and the position of the aerodynamic centre of the wing.Changes in stiffness are found to have highly nonlinear effects on the resultant bending moments, requiring full calculation of the entire design space.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
