Structural analysis of different materials used in ornithopter for better strength and application

Abstract

An ornithopter is a biomimicry of a flying bird or insect which is power-driven by an electronic powered battery and mechanical components such as a gearbox and spars. These bio-inspired flying robotic vehicles are being inspected and developed for various applications in their field but are currently not at that level to have a successful flight. It is not easy to select a such material for better achievement and performance of an ornithopter which must withstand not only aerodynamically forces applied on it but also damages occur during its performance segments just like as take-off, cruising, different altitude, landing, or any activities enrolled by ornithopter. The core objective of this paper is to provide a material for an ornithopter that gives a better stand respect to applied load i.e., stress and varying strain limit from the initial low to its fracture point with respect to materials like Aluminium alloy, E-glass fibre-honeycomb, Titanium alloy, Carbon fibre etc. A FEA analysis is done to understand these problems and to analyse the various elements to make sure suitable material has been chosen.
