Bird Aerodynamic Experiments
The senior author’s research in the area of skin friction reduction by compliant coatings led him to investigate the aerodynamic properties of bird feathers. Three separate experiments performed during the last several years are reported in this paper. The experiments are: (1) relation between the compressive modulus of bird feathers and bird maximum level flight speed (2) the effect of flexible slotted-tip feathers on the wing-wake vorticity and (3) the effect of owl leading edge barbs on lift and drag characteristics of wings.
