Effects of deformation and vibration characteristics of wings on flapping flight
Mechanical Engineering Journal, 2015 The dragonfly wing is passively deformed under flapping and has the strength to withstand high flapping frequency simultaneously. These characteristics of deformation and vibration of the wing are important for flapping flight.

Formation of the leading-edge vortex and spanwise flow on an insect-like flapping-wing throughout a flapping half cycle [PDF]
, 2013 This paper presents an experimental investigation of the evolution of the leading-edge vortex and spanwise flow generated by an insect-like flapping-wing at a Reynolds number relevant to flapping-wing micro air vehicles (FMAVs) (Re = ~15,000 ...

Periodic and chaotic flapping of insectile wings [PDF]
The European Physical Journal Special Topics, 2015 Insects use flight muscles attached at the base of the wings to produce impressive wing flapping frequencies. The maximum power output of these flight muscles is insufficient to maintain such wing oscillations unless there is good elastic storage of energy in the insect flight system.
