Convolution/Volterra Reduced-Order Modeling for Nonlinear Aeroelastic Limit Cycle Oscillation Analysis and Control
Cameron S. D. Brown,Gregory McGowan,Kilian Cooley,Joe Deese,T. Josey,Earl H. Dowell,Jeffrey L. Thomas +6 more
TL;DR: In this paper , a methodology for leveraging a combination of linear (through convolution integrals) and nonlinear (through Volterra series) reduced-order modeling (ROM) development was demonstrated on both a two-and three-degree-of-freedom (2DOF and 3DOF, respectively) aeroelastic system.
Proceedings ArticleDOI
A novel experimental mechanics method for measuring the light pressure acting on a solar sail membrane
TL;DR: In this paper, a gravity-based measuring method for light pressure acting on membrane is presented, which can not only be applied to study the dynamics characteristics of solar sail membrane structure with different light forces, but could also be used to determine more accurate light forces/loads acting on solar sail films and hence to enhance the determination of the mechanical properties of the solar sail membranes structure.
Journal ArticleDOI
Revisiting the Fundamentals of Control Surface Reversal Including Nonlinear Effects
TL;DR: Control surface reversal is a classical aeroelastic phenomenon commonly investigated during aircraft development as discussed by the authors, and it occurs under static equilibrium between the elastic restoring torque and the aerodynamic force.
Nonlinear Reduced-Order Modeling of Limit Cycle Oscillations of Aircraft Wings and Wing/Store
TL;DR: In this article, a method for calculating transonic limit cycle oscillations (LCO), flutter and other nonlinear aeroelastic phenomena has been developed to solve the general 3D Euler and Reynolds Averaging Navier-Stokes (Eulen/RANS) equation.
