Experimental investigation on effect of fluid structure interaction in ma micro air vehicle

Abstract

Micro aerial vehicles are tiny forms of unmanned air vehicles. These types of MAVs are suitable for military surveillance and aerial photography due to its small size, weight, low noise and the ability to escape detection radar. Since it is advanced most of the unmanned aerial vehicles have become smaller in size. These types of aerial vehicles are normally operated at low Reynolds number and the materials used for the wing structures are thin and light weight. Hence, the effect of fluid-structure interactions plays an important role in the aerodynamics performance. Birds and insects animated among humans created the desire to fly. They examined the structure of wings that helped birds and insects to fly. Since aerodynamics parameters vary with wing shape and structural deformation, this study will be useful for the people who are going to develop the same in future for surveillance or biochemical sensing at remote or hazardous areas.The experiment was conducted using a low-speed wind tunnel that can be operated at a minimum speed of a fan. The speed of the fan can be controlled by a regulator and calibrated for different free stream velocities. The model is attached to a three-component balance system and the balance is attached to the sting. The three-component balance can detect the axial and perpendicular or normal forces and bend along an axis perpendicular to the axial and normal axis. newline
