Scientists at the Royal Veterinary College, London reveal surprising aerodynamic behavior during bird’s flight, using LaVision measurement technology
Tuesday, 11. February 2020
The research group of Professor Richard Bomphrey and Professor Jim Usherwood, from the Royal Veterinary College (RVC) in London, has successfully used LaVision’s Helium-filled Soap Bubble (HFSB) generator and LED illumination to gain new insights regarding the aerodynamics of bird flight.
Using the large-scale nature of LaVision’s HFSB seeding together with the eye-safe LED volumetric illumination and high-speed imaging, the researchers at RVC could visualize the aerodynamic footprint of various birds of prey (hawks and owls).
Quantitative analysis using our state-of-the-art Shake-the-Box (STB) processing algorithms allowed the researchers to draw valuable conclusions from the 4D particle tracks, including a detailed view on the unexpected behavior of the tail feathers of the birds.
