WebSep 4, 2024 · Research published recently showed that the Andean Condor—the heaviest soaring bird, at 35 pounds—flaps less during flight than any other free-ranging bird. After following eight Andean Condors for five years, a team of European and Latin American scientists found that even young birds soar about 99 percent of their flight time.

Similarly, in the heaving gait, the flapping wing makes its drag–thrust transition at constant $2Af/U=0.16$. The difference in the numbers, between 0.28 and 0.16, reflects the difference in the gaits used by the flapping wing.
WebJan 29, 2024 · Recent research by Taha et al. [ 2, 3] shows that coordinating the wing pitch angle with the wing swing movement improves flight aerodynamics. This paper presents the synthesis procedure for a one degree-of-freedom flapping wing mechanism that coordinates the wing swing and pitch angles to achieve a specified performance.
