• W2125733279 abstract "The objective of the present work is an numerical analysis of flutter elements of a typical airfoil using a classical method with direct eigenvalue method for the undamped case (forced oscillation). The dynamic coupling of the airfoil structure into two-dimensional aerodynamic flow was simulated with ultra-low Reynolds number so that the aeroelastic mo- tion of the airfoil in the flow could have simulated in the time domain. The intention was to determine the flutter elements in the small wings (like a Micro air vehicle), using a two- dimensional aerodynamic code based on Virtual Boundary Method, suitably coupled to the airfoil structural characteristics. The symmetric NACA 0012 airfoil was choosed to simulate the time history of flow parameters. The airfoil was considered as a rigid section, supported by translational and rotational springs, so that only heave and pitch degrees of freedom are permitted at the point of support. The pitching and heaving movements where simulated sep- arately. The effects of forced oscillation were analyzed an attack angle of0 o for heaving, and vertical oscillation of±0.1 of chord length; pitching of±2 o with frequency (sinusoidal),fs , of 1Hz, 2Hz, 5Hz and 10Hz. The effects of the reduced frequency (k), amplitude of forced oscillation (h) and the maximum non-dimensional flapping velocity (kh) on the thrust genera- tion were analyzed. The pressure coefficient CP, lift L, lift coefficient CL, drag coefficient CD and pitching moment M about the support point were computed. The results obtained were compared and agree with the literature ones. The problem of calculating the response of a system subject to an external excita- tion (forced oscillation), since the mathematical model and of the structure properties (natural frequencies, damping factors and natural modes of vibration) from the input and output in- formation, in general is a difficult problem to be solved and form part of the class of inverse problems. Among the methods that treat these problems, the analysis modal methods are char- acterized by direct calculation of the modal parameters of the structure and, computationally, these parameters can be determined directly from the simulation results, in the time domain" @default.
