Conceptual Study of Ornithopter for Better Future Performance and Application

Abstract

An ornithopter is a power-driven aircraft that utilizes a flapping mechanism. This paper summarized the research and development carried on Unmanned Aerial Vehicle (UAV) till date and reclaims the efficiency on ornithopter namely the flapping frequency, Reynold number, kinematics, transmission system and flapping mechanisms. The present investigation explores the design of a biologically inspired flying Unmanned Aerial Vehicle. For its execution, varied of analyses of flight mechanics, stability, and the control of flapping motion. The theoretical techniques involved in the construction of an ornithopter have investigation for surveillance, military application, spy work, and rescue operations. Additionally, the material used for construction of ornithopter is also discussed. The benefits of the flapping mechanism for are not limited. This paper also reviews the research and development done on the previous UAVs and from small birds to large birds. In this paper the experimental analysis has been done on the ANSYS Fluent on a semi elliptical wing design with a wingspan of 0.25m which delivered the output of how the wind flow and pressure can affect the efficiency of a flapping wing according to the varying angle of attack. This concluded the selection of a material with low stiffness.
