Low cost Small size – Wingspan < 15cm, weight < 500g Flight behavior changes Aerodynamics more common to small birds and insects
How can we simulate birds flight ?
Computational Simulation Simulating flapping wing flight Computational models of the fluid, structures and full morphing body dynamics
Bat Flight Extremely maneuverable animals Efficient and effective flapping vehicles Morphing membrane instead of feathered wings
Bat Flight Motion Capture Breuer Lab and Swartz Lab (Brown University) High speed stereo digital video capture in wind tunnels and flight cages Body motion tracking using markers Fluid measurements using smoke

The power of visualization Without a visualization the simulation would be only numbers People understand better the results by actually looking at the flight simulation They can visually compare the actual bat flight with the simulated one
