Presentation Transcript

  1. Computational Bat Flight Visualization Victor Mateevitsi

  2. First attempt

  3. Flight in the 20th century

  4. Genesis • Aeronautical engineering used animal flight • Unmanned Aerial Vehicles (UAV) • Uninhabited Micro Aerial Vehicles

  5. Uninhabited Micro Aerial Vehicles • Low cost • Small size • Wingspan < 15cm, weight < 500g • Flight behavior changes • Aerodynamics more common to small birds and insects

  6. How can we simulate birds flight ?

  7. Computational Simulation • Simulating flapping wing flight • Computational models of the fluid, structures and full morphing body dynamics

  8. Bat Flight • Extremely maneuverable animals • Efficient and effective flapping vehicles • Morphing membrane instead of feathered wings

  9. 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

  10. Videos • http://breuerlab.engin.brown.edu/research/batflight.html

  11. Videos

  12. 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
