Wing Shapes and Flight - Stanford University

The shape of the wing is important in determining the flight capabilities of a bird. Different shapes correspond to different trade-offs between advantages such as speed, low energy use, and maneuverability. Two important parameters are the aspect ratio and wing loading. Aspect ratio is the ratio of wingspan to the mean of its chord (or the square of the wingspan divided by wing area).

WebWing loading is the relationship between total body mass in grams and total wing area, it is expressed as grams of body mass over wing area in cm square. One example is Long-tailed Hornbill (Tockus albocristatus) which weighs about 297 gram has wing loading of 0.175 has light buoyant flight. Birds use mainly three types of flight, distinguished by wing motion. When in gliding flight, the upward aerodynamic force is equal to the weight. In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight. For specialist soaring birds (obligate soare…

WebSep 11, 2015 · Birds have wings that are attached to the torso with truly massive muscles compared to the rest of the bird.
