Title
Aerodynamics Of Soft Flapping Wings Of Caudipteryx
Abstract
This study explores the aerodynamic capacity of feathered forelimbs of Caudipteryx, the most basal non-volant maniraptoran dinosaur, with particular focus on flapping during terrestrial locomotion on a flat, horizontal substrate. In order to seek this subject, Caudipteryx and its wings have been modeled theoretically based on measuring the fossil data of Caudipteryx (IVPP V12344 and IVPP V12430). We divided the wings into various elements to enhance the analysis accuracy, and lift and thrust forces were estimated using a mathematical model and metabolic energy required to flap the forelimbs was estimated. Here we show that flapping feathered wings of flightless Caudipteryx would generate small amounts of aerodynamic forces based on our kinematic assumptions. Although the function of pennaceous feathers in oviraptorosaurs is uncertain and the feathers of dinosaur were believed not to originate for flight, theoretical analyses indicate that the feathered wings of Caudipteryx, could have produced small aerodynamic forces in rapid terrestrial locomotion. The winged Oviraptorosaurs utilized their feathered wings to produce aerodynamic forces in cursorial activities. Modeling of flapping while running showed similar limited aerodynamic force production.
