Abstract

The unsteady vortex lattice method is used to model the oscillating plunging, pitching, and flapping motions of a finite-aspect-ratio wing. Its potential applications include design and analysis of micro Unmanned Air Vehicles and in studying the high frequency flappling flight of insects and small birds. The results were verified by theory and in the plunging and pitching cases, by experimental data. The model includes free wake relaxation, vortex stretching, and vortex dissipation effects and is implemented using object oriented and parallel computing techniques. The results suggest that with a more sophisticated kinematic model of the wing motions and further parallelization of the code, the model will be able to simulate, and provide 3D visualizations of the wake in complex flapping flight, including hovering.
