Bird Flight 101: Explaining The Mysteries Of Airflow & The Bird
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… WebTheir wings are long and pointed and can span up to 2.3 metres (7.5 ft), the largest wing area to body weight ratio of any bird.

WebSep 11, 2015 · Birds have wings that are attached to the torso with truly massive muscles compared to the rest of the bird. These wings would need to use a kinematic chain similar to humans do when jumping. This kinematic chain would connect the arm musculature to the wings and allow strength from the chest muscles to be passed through to the wings. can alexa\u0027s voice tone be changed
