Resumen:
Insect-like hovering dynamics of flapping-wings is of great
importance for the engineering of micro-air-vehicles (MAV) and also of
importance to comparative morphologists. Given the rich variety of wing shapes,
sizes, and kinematics it is hard to determine optimal wing-flapping patterns,
in the sense of maximizing lift with minimal energy consumption. To determine
optimal wing geometry and kinematics we use a genetic algorithm that explores a
high-dimensional parameter space, including wing size, aspect ratio, axis
position, amplitude, phase, and frequency of
each of the three independent angular motions, including also a variety
of angular time function shapes. The fluid forces and moments on the wing that
allow to determine lift and energy consumption are evaluated using a model
previously developed by one of the authors. Different optimal solutions appear that are considered for
MAV, and also compared with actual insect flight patterns.
