Development of Tailless Flapping Wing System With 2.4 GHz Wireless Communication
ABSTRACT: Recently, there have
been studies on characteristics of flapping motion of small birds and insects
in flight where in that size category; flapping wing designs excel over their
fixed wingcounterparts. Despite that, complexities of wing motion and
biomechanism of birds andinsects added many difficulties to build an efficient
flapping mechanism, especially thatwithout tail configuration. In an attempt to
overcome such difficulties, two motor-driven flapping wing system micro aerial
vehicles (FW-MAV) were developed without tailconfiguration. First FW-MAV has
one DC motor to drive its wing motion and optionally magnetic actuator for
maneuverability. The second FW-MAV has two DC motors that can separately
generate flapping wing motion. In addition, 2.4 GHz wireless communication wasalso
implemented to both FW-MAV to remotely control the wing actuators. Then to
evaluate their flight efficiency, flapping motion of the two FW-MAVs were
evaluated based on kinematics simulation and flapping frequency test
measurement. Further, thrusts produced by both FW-MAVs were also measured and
compared. Based on the measurement, FW-MAV with two motors was about 4% heavier
than the other FW-MAV, but it can generate about10% larger flapping angle and
about 3 times of thrust.
