DRIVING APPARATUS USING PIEZOELECTRIC ACTUATOR AND AIR VEHICLE THEREOF TO FREELY FLY FRONTWARD, BACKWARD, UPWARD AND DOWNWARD BY CONNECTING TWO DRIVING APPARATUSES AND BLADES THROUGH COUPLINGS

摘要

PURPOSE: A driving apparatus and an air vehicle are provided to make a flying object fly upward, downward, frontward and backward freely by realizing the motion of a bird or an insect's wings. CONSTITUTION: A flapping apparatus(300) and a lagging apparatus(400) comprise driving arms, rotors, piezoelectric actuators, housings, insertion grooves and guide slots respectively. The driving arms generate flapping or lagging displacement by adding force to the end of blades. The rotors rotate the driving arms vertically or horizontally. The piezoelectric actuators rotate the rotors by forming driving grooves in the rotors and inserting in the driving grooves. The housings store the rotors. The insertion grooves are formed in the housings to insert the piezoelectric actuators. The guide slots guide flapping or lagging movement passages of the blades by the driving arms. Thereby, an airplane to be freely flown upward, downward, frontward and backward is realized.
