Dragonflies have elastic wings with varying section camber. Fore- and Hindwings with a phase shift.
Aircraft wing parameters of PreCAD software have been adapted to these requirements.
Experimental data are needed for simplified but somewhat realistic simulation.
Various flight mode observations are being analyzed.
Work in progress!
Animation with rigid wing arbitrary flapping and phase shift only
4D Model with flapping, phase shift, flexible wing camber and bending
