Aerodynamic force platform
- The aerodynamic force platform as an ergometer
Summary: An accurate method for measuring the time-resolved aerodynamic power generated during free flight using direct force measurements from an aerodynamic force platform and the measured 3D wing velocity.
- How the hummingbird wingbeat is tuned for efficient hovering
Summary: Integrating aerodynamic, kinematic and muscle recordings confirms Weis-Fogh's hypothesis that hummingbirds and flies converged on a wingbeat driven by elastic recoil that incurs low induced power to hover efficiently.
