Title:
ORNITHOPTER
Document Type and Number:
WIPO Patent Application WO/2018/028569
Kind Code:
A1
Abstract:
Disclosed is an ornithopter, with the specific structure of an airfoil being made into a single-side breathable structure. In the case where the airfoil flutters downwards, air does not pass through the airfoil, resistance is produced and becomes a lifting force and a driving force of the ornithopter; during the process of the airfoil fluttering upwards, the airfoil is in a breathable state so as to reduce air resistance without impeding the lifting force of the ornithopter; and after the airfoil of the ornithopter flutters downwards to generate the lifting force and a forward thrust force, the resistance is maximally reduced during the process of the airfoil fluttering upwards, and the energy consumption is reduced, thereby solving the problems of existing ornithopters being unable to fly with a load and the flight duration being short.
