Flapping wings enable flying animals and biomimetic robots to generate elevated aerodynamic forces. Measurements that demonstrate this capability are based on experiments with tethered robots and animals, and indirect force calculations based on measured kinematics or airflow during free flight. Remarkably, there exists no method to measure these forces directly during free flight. Such in vivo recordings in freely behaving animals are essential to better understand the precise aerodynamic…

Design and analysis of aerodynamic force platforms for free flight studies

New advancements in the design of the aerodynamics force platform are described and explained, a novel instrument that can directly measure the aerodynamic forces generated by freely flying animals and robots, and the design principles can also be translated to other fluid media.

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.

Fluid moment and force measurement based on control surface integration

The moments and torques acting on a deforming body determine its stability and maneuverability. For animals, robots, vehicles, and other deforming objects locomoting in liquid or gaseous fluids,

High Fidelity Aerodynamic Force Estimation for Multirotor Crafts in Free Flight

Using the experimental framework for estimating multirotor free-flight forces, a closed-form expression which incorporates Reynolds number and rotor-rotor interaction effects is developed, which accurately estimated rotor performance during various vertical flight conditions with a high degree of accuracy.

Aerodynamics of bird flight

Unlike airplanes birds must have either flapping or oscillating wings (the hummingbird). Only such wings can produce both lift and thrust – two sine qua non attributes of flying.The bird wings have

Nonintrusive 3D fluid force measurements are still challenging to conduct accurately for freely moving animals, vehicles, and deforming objects. Two techniques, 3D particle image velocimetry (PIV)

Flapping wing aerodynamics: from insects to vertebrates

By comparing flapping flight across insects and vertebrates, it is identified how their morphology and kinematics govern both shared and distinct aerodynamic mechanisms, and open research questions in animal flight are highlighted.

The biophysics of bird flight: functional relationships integrate aerodynamics, morphology, kinematics, muscles and sensors

Research at the interface of the systems used in flight control is reviewed and several common themes are discussed, including wing velocity about the shoulder, shape within the wing, and angle of attack.

All animals flap their wings in powered flight to provide both lift and thrust, yet few human-engineered designs do so. When combined with flexible wing surfaces, the resulting unsteady fluid flows

Aerodynamic effects of flexibility in flapping wings

It is shown that aerodynamic forces can be controlled by altering the trailing edge flexibility of a flapping wing, which can be useful for wing design for small robotic insects and, to a limited extent, in understanding the aerodynamics of flapping insect wings.

Pigeons steer like helicopters and generate down- and upstroke lift during low speed turns

This work examined net aerodynamic forces and body orientations in slowly flying pigeons (Columba livia) executing level 90° turns and found that pigeons achieve low speed turns much like helicopters, by using whole-body rotations to alter the direction of aerodynamic force production to change their flight trajectory.

Wing inertia and whole-body acceleration: an analysis of instantaneous aerodynamic force production in cockatiels (Nymphicus hollandicus) flying across a range of speeds

Investigating the variation in instantaneous aerodynamic force production during the wingbeat cycle of birds flying across a range of steady speeds found that the inertial power requirements of downstroke were consistent with the assumption that nearly all wing kinetic energy in downstroke was applied to the production of aerodynamic forces and therefore should not be added separately to the overall power cost of flight.

Transition from leg to wing forces during take-off in birds

Measurements of both leg and wing forces during take-off and the first three wingbeats in zebra finch and diamond dove reveal a novel transitional role for the first wingbeat in terms of force production, underscoring the relatively low contribution of the wings to initial take-offs.

It is vital to test the metabolic costs of intermittent flight to understand why some birds use intermittent bounds during slow flight, and experimental designs of maneuvering and stability should measure inertial and aerodynamic forces.

The aerodynamics of avian take-off from direct pressure measurements in Canada geese (Branta canadensis)

These observations suggest that tertials provide weight-support throughout the wingbeat, that the wingtip provides thrust during upstroke and that the kinetic energy of the rapidly flapping wings may be dissipated via retarding aerodynamic forces (resulting in aerodynamic work) at the end of downstroke.

Lift production in the hovering hummingbird

It is shown that while the hummingbird wing is strongly influenced by similar sharp-leading-edge aerodynamics, leading edge vorticity is inconsistent, and a near-continuous lift production through wing turn-around, previously unknown in vertebrates, able to contribute to weight support as well as stability and control during hovering.
