Aerodynamic Measurements of Maneuvering Brown Long-Eared Bats

Dryad hosts data from a study examining the aerodynamics of maneuvering flight in brown long-eared bats (Plecotus auritus). The dataset links kinematics and aerodynamics, derived from particle image velocimetry and high-speed filming of bats performing sideways maneuvers in a wind tunnel. It was authored by Per Henningsson and last updated in June 2020.

Use Cases

• Analyze asymmetries in lift and thrust/drag forces during wingbeat upstroke and downstroke to model maneuver mechanics.
• Train models to classify the three main aerodynamic modes (lift asymmetries during downstroke, thrust/drag asymmetries during downstroke, thrust/drag asymmetries during upstroke) from kinematic sequences.
• Correlate high-speed filming data with particle image velocimetry outputs to validate aerodynamic force predictions for animal flight.

Strengths

• Data is derived from controlled wind tunnel experiments combining particle image velocimetry and high-speed filming.
• Findings challenge prior predictions, showing bats more frequently use upstroke than downstroke to generate maneuvering asymmetries.
• The dataset is openly available under a CC0 1.0 public domain license.

Limitations

• The dataset scope is limited to a single species (Plecotus auritus) performing basic sideways maneuvers, limiting generalizability.
• Sample size and specific data volume (rows, columns) are not provided in the input description.
• Data collection occurred in an artificial wind tunnel environment, which may not fully represent natural free-flight conditions.
