Flapping propulsion
WebJan 16, 2024 · A conceptual design of bionic Autonomous Underwater Glider (AUG) is introduced, with a pair of flapping wings. The immersed boundary method is employed and Navier–Stokes equations are solved to investigate the propulsive performance of the bionic AUG with Aspect Ratios (ARs) of the flapping wings varying from 0.36 to 5. The … WebSep 22, 2024 · The propulsion system also includes elastic elements for energy recovery, hence is an imperative part of this class of energetically demanding flapping vehicles. A video is provided in the electronic supplementary material for the propulsion system shown in figure 1 built using commercial off-the-shelf components.

WebMar 3, 2024 · Cetacean propulsion by a periodic flapping motion of their fluke is considered and studied on a benchmark flexible straight wing. The aim of the study was to validate low-order models for this configuration. WebUndulatory Swimming. For a wide variety (perhaps a majority) of fishes, the dominant propulsion mechanism involves wagging or "flapping" the aft-most portion of their body, namely, their caudal or "tail" fin. Because the caudal fin is attached to the rest of the fish body, flapping of this fin is achieved by moving forward portions of the fish ...
