Dimensional analysis of spring-wing systems reveals performance metrics for resonant flapping-wing flight. [PDF]
J R Soc Interface, 2021 Flapping-wing insects, birds and robots are thought to offset the high power cost of oscillatory wing motion by using elastic elements for energy storage and return. Insects possess highly resilient elastic regions in their flight anatomy that may enable

The aerodynamic effects of wing–wing interaction in flapping insect wings
Journal of Experimental Biology, 2005 SUMMARYWe employed a dynamically scaled mechanical model of the small fruit fly Drosophila melanogaster (Reynolds number 100–200) to investigate force enhancement due to contralateral wing interactions during stroke reversal (the `clap-and-fling'). The results suggest that lift enhancement during clap-and-fling requires an angular separation between ...
