Abstract:
A dragonfly-like miniature four-winged ornithopter, comprising: an airframe (101), two front flapping wings (102), two front wing connection members (103) with connecting rods, two rear flapping wings (104), two rear wing connection members (105) with connecting rods, a driving gear (106), a shaft gear (107), a first stage gear (108), two second stage gears (109) with connecting rods, two third stage gears (114) with connecting rods, two front ball joint connecting rods (110), two rear ball joint connecting rods (111), two engine connecting rods (112), two engines (113), and a brushless direct current motor. The dragonfly-like miniature ornithopter is based on a bionic design, is lighter overall compared to the existing fixed-wing and rotary-wing aircrafts, has a high energy utilization rate, is suitable for a low Reynolds number flight environment, and can be widely applied in low-speed and high-maneuverability flight scenarios.
