The aim of the present work is the development and modal analysis of hummingbird inspired MAV flapping wings. Carbon nanotubes (CNTs)/epoxy nanocomposite is chosen as the material for wing fabrication. The nanocomposite has been developed and characterized using dynamic mechanical analyzer for its dynamic viscoelastic properties. Wing designing is done by obtaining the data points from 2D full-flexed giant hummingbird wing image using digitizer. The fabrication of wings is done using molding manufacturing technique. Wing mold is made out of Perspex sheet using laser engraving machine. Modal analysis has been performed in air/normal environment and vacuum chamber. The results are used for determining the repeatability of wing manufacturing technique, too. A 3D model of wing is used for computational modal analysis using commercial finite element software ANSYS. The results from experiments and ANSYS simulations are compared and found in good agreement with each other.

Flapping wing micro air vehicles (FWMAVs) are small unmanned aircrafts or flying robots which are intended to be used for surveillance, reconnaissance, biochemical sensing, targeting, tracking, etc. To perform such missions, MAVs are required to do some specific operations such as hovering; slow and high speed flying; quick landing and takeoff , etc. During flapping motion through surrounding air, wings experience inertial and aerodynamic forces. For making successful flights in such conditions, wings must have properties such as flexibility, strength, low weight, long fatigue life, etc. For producing such properties, wing material plays a crucial role. Most of the research related to MAVs is based on aerodynamics and controls. Present research is based on materials and structural aspects of flapping wings. Here materials used are carbon fibres for making wing skeleton and polyethylene for wing membrane. The design for the wing of 113.8 mm length is inspired from giant hummingbird's wing. The wing sketch was developed in gambit software by taking position data, generated using digitizer, from printed image of hummingbird wing. Developed sketch was printed and used, as a guide, for making the wing skeleton. The polyethylene film with adhesive was laminated on the skeleton at 150 ºC. Natural frequencies, nature of mode shapes, and damping characteristics of fabricated wings are determined here.
