ORNITHOPTER FLYING ACCORDING TO A WING FORMED IN THE BODY, WHICH IS MOVED UP AND DOWN

摘要

PURPOSE: An ornithopter is provided to minimize resistance in a section in which acceleration is changed so as to effectively perform aviation according to fluttering. ;CONSTITUTION: An ornithopter comprises a body(100), a wing pivot axis(20), a wing(30), a drive motor(40), a rotating speed change unit(50), a wing driving shaft(60), a flutter driving bar(70), a wing rotation driving shaft(80), and a wing rotation driving bar(90). A support bracket is projected downward inside the body. The wing pivot axis penetrates the upper part of the body and rotatably combined with the body. A driving connecting bar is formed in the center of the wing pivot axis. The wing is rotatably combined with both ends of the wing pivot axis. The drive motor is fixed to the inner side of the supporting bracket of the body. The rotating speed change unit is fixed to the bottom of the support bracket of the body and outputs constant angular velocity of 360 degrees of a common input shaft continuously rotating in connection with the drive motor as different velocities through an output shaft. The wing rotation driving shaft penetrates the lower part of the body and continuously rotates in connection with the output shaft of the rotating speed change unit. A first crank is installed on both sides of the wing driving shaft.;COPYRIGHT KIPO 2011
