Automated aerodynamic performance estimates for flapping flight
The aerodynamic performance of freely flying birds is inherently difficult to measure directly without interfering with their natural flight. Many current methods thus combine kinematic parameters derived from high-speed video with theoretical force and power models. However, these methods often require manual tracking of points in each frame of a video to obtain kinematic data. This project ut...
متن کاملUnsteady aerodynamic forces of a flapping wing.
The unsteady aerodynamic forces of a model fruit fly wing in flapping motion were investigated by numerically solving the Navier-Stokes equations. The flapping motion consisted of translation and rotation [the translation velocity (u(t)) varied according to the simple harmonic function (SHF), and the rotation was confined to a short period around stroke reversal]. First, it was shown that for a...
متن کاملSymmetry breaking leads to forward flapping flight
Flapping flight is ubiquitous in Nature, yet cilia and flagella, not wings, prevail in the world of micro-organisms. This paper addresses this dichotomy. We investigate experimentally the dynamics of a wing, flapped up and down and free to move horizontally. The wing begins to move forward spontaneously as a critical frequency is exceeded, indicating that ‘flapping flight’ occurs as a symmetry-...
متن کاملFlapping wing flight can save aerodynamic power compared to steady flight.
Flapping flight is more maneuverable than steady flight. It is debated whether this advantage is necessarily accompanied by a trade-off in the flight efficiency. Here we ask if any flapping motion exists that is aerodynamically more efficient than the optimal steady motion. We solve the Navier-Stokes equation governing the fluid dynamics around a 2D flapping wing, and determine the minimal aero...
متن کاملQuantitative Measurements of Forward Flapping Flight Using Image Processing
A method for automatically calculating the flight kinematics of a flapping bird flying on a relatively dense background environment was developed. The algorithm is able to calculate the bird’s flapping frequency, wingbeat phase, forward velocity, and forward acceleration with good accuracy with the use of only one camera. Image processing was used for extracting the bird’s silhouette from the b...
