The characterization of tandem and corrugated wings
Y Lian, T Broering, K Hord, R Prater - Progress in Aerospace Sciences, 2014 - Elsevier
Dragonfly wings have two distinct features: a tandem configuration and wing corrugation.
Both features have been extensively studied with the aim to understand the superior flight …

Performance augmentation mechanism of in-line tandem flapping foils
LE Muscutt, GD Weymouth… - Journal of Fluid …, 2017 - cambridge.org
The propulsive performance of a pair of tandem flapping foils is sensitively dependent on the
spacing and phasing between them. Large increases in thrust and efficiency of the hind foil …

The effect of phase angle and wing spacing on tandem flapping wings
TM Broering, YS Lian - Acta Mechanica Sinica, 2012 - Springer
In a tandem wing configuration, the hindwing often operates in the wake of the forewing and,
hence, its performance is affected by the vortices shed by the forewing. Changes in the …

The four-flipper swimming method of plesiosaurs enabled efficient and effective locomotion
The extinct ocean-going plesiosaurs were unique within vertebrates because they used two
flipper pairs identical in morphology for propulsion. Although fossils of these Mesozoic …
